Found an English translation of a Belgian (in French) article about damascus production



Looking at the end of the 'ribbon', one can understand the various patterns that can be produced by alternating the tiny iron bars with steel. The 'Damas' illustrated certainly looks like what Lefever (and others) called 'Horse-shoe' damascus.

Lots of new stuff on the 'Damascus Barrels' PictureTrail
http://www.picturetrail.com/gallery/view?p=999&gid=16082038
including an amazing Parker brl with 'Terell' in the damascus pattern.
Posted By: Drew Hause Re: Damascus explained - 05/08/07 05:04 PM
The strips of iron and steel in the 'ribbon' shown will produce a pattern similar to "Bernard" damascus. Also note the tiny 'roses' in the right barrel.

Posted By: Drew Hause Re: Damascus explained - 05/08/07 09:36 PM
Just had a very gracious offer from one of the regular contributors here to share illustrations of about 30 damascus variants. My long suffering but much smarter spouse will get it scanned and added to the PictureTrail on arrival and I'll post when it's up.
Would still like to add high resolution close-up pics of some high grade Parker and LC Smith damascus. Please send by JPG attachment to revdoc2@cox.net and thanks!

Dave Miles comes through again! He has a copy of the excellent article covering the Belgian damascus barrel makers from the April 1976, American Rifleman "Making Damascus Barrels"
Send me your e-mail address if you'd like me to forward the copy (please tell me I can't get in trouble for this!)

Thank you both! Brings thots of geezers before they were, old guns that weren't and dogs that knew what they needed to know to please their masters long before there were rings or trials.

Oh, and I like the fact that the rib is joined to a piece of homogenous steel for the doll's head, too.

Here is a thread about making damascus for knife making. The guy that is doing this is not a barrel maker of course, but he is some sort of Guild-equivalent master of this sort of work. He has some video clip of the early part of the process and some discussion of what's happening.

There are lots of pretty knives out there, but his are a "cut above" the rest. Pun perfectly appropriate.....

Meanwhile some beautiful barrels here and I could stand to learn a lot about the different English damascus guns that I have (3 rifles, and several shotties).

Found some more excellent pics of Lefever and Baker damascus on the Greg Martin Auctions site, including this Optimus (which might be Truk Extra or extra fine Turkish damascus)



I also asked the Remington Society if they can come up with the name used on E and D Grade 1894s. Should have the 1899 Parker catalog reprint soon and the poster illustrating about 30 kinds of damascus (which we'll scan and post.)

Many thanks to Pete M who graciously shared a c. 1900 product brochure by a Belgian brl maker. Some detail was lost in the scanning and posting, but it's up now http://www.picturetrail.com/gallery.fcgi?p=999&gid=16082038
Interesting findings include several examples of a One Iron Crolle-Twist Laminate and 5 grades of "Turkish damascus" which appears to be what US gunmakers primarily used, but which was given names like "Boston, Oxford, Washington, American Flag, Horseshoe, etc." for marketing. The Lefever brls in the previous post look like either 1st quality Bernard or Leclere.
Posted By: PeteM Re: Damascus explained - 05/13/07 01:44 AM
Dr Drew,

Glad you got it. Here are some more images.

Remington 1894 C grade - Star Damascus. Notice the rib.


Embedded name Zenobe Gamme. Dr Gaddy once posted some actual photos of this type of work. I just did not save them. Maybe some else did. Hopefully they will post them.


From Puraye's Le Damas. Identified by Gaier as one of the last workshops still making damascus tubes circa 1920


Modern Damasteel. A very different product with some resemblance to traditional damascus

Let us remember that Damascus knife blades are completely differeent from Damascus gun barrel. Both are beautiful, however. I have obtained a bunch of twist and Damascus steel baeel cut offs that I am going to have made into knife blades. For the proper edge hardness, there will be a center core of regular knife steel. Should be very neat.

Rev, I sure would like to add to my American damascus/twist files if you have anything...I only have a few bits and peices and some of are for faux damascus...You don't have to answer if you don't want to, I am aware that American damascus and faux damascus were "off limits" subjects [here] in the past...we can exchange info privately if you think it may help to avoid a pissing match by angry readers..
.
Did you happen to catch that episode of Globe Trekker (in Spain) were they claimed the history of damascus steel is interwoven with the history of flaminco (sp?) music and dance?
Posted By: Rocketman Re: Damascus explained - 05/24/07 07:11 PM
RC - didn't see that episode. Were they refering to the twisted laminate we refer to as damascus for gun barrels, or were they refering to actual Damascus blades made from Wootz. The two are different. I've never heard of Spain being a developer of laminate metal.
Posted By: Drew Hause Re: Damascus explained - 05/24/07 07:16 PM
Robert: I suspect everything shown on the 'Damascus Barrels' PictureTrail is English or Belgian
http://www.picturetrail.com/gallery.fcgi?p=999&gid=16082038
and I only have one 'Faux damascus' pic (the last one)

Missed the Globe Trekker episode. Lots of stuff out there about damascus blade production (much less about gun barrels). The Moors controlled much of Iberia from 700-1200, and Grenada until 1492, and no doubt brought sword blade 'technology' with them. These folks claim the Flamenco came from Middle Eastern Dance http://www.middleeasterndance.net
Posted By: Robert Chambers Re: Damascus explained - 05/25/07 02:29 AM
according to the program that I saw...there is a valley in Spain were it is said that Flamenco music got it's start aganst the constant backdrop of ringing anvils that went 24 hrs a day on both sides of the valley.
.
Twenty years ago I read where farriers across Europe saved the worn and headless horse shoe nails for re-use in the damascus steel process. It was theorized that the nails had enhanced grain properties due to the horses constant pounding on the cobblestones. These nais were then straightened, filed, and welded with a blacksmith weld, into long somewhat square rods. These rods where then filed, to open the grain, and bundled into packets, with ground bone dust, to be forged and twisted into damascus or composite steel. This is probably nothing new to you guys.
.
What interests me is the damascus [gun barrel] steel that was made near Ithaca and in New York City and Boston. I guess I'm also interested in the damascus steel axes and hatchetts from around America, but mostly the the ones made by the Seneca Indians in Lackawanna NY, some under the name Buffalo Black Axe. The federal government played a role in setting up the steel industry in Lackawanna, mainly to employ the Senacas who were being forced to give up their hunting and gathering metheods of survival. I've heard, but not seen, that some of the best L & IJ White carpenters tools where available with Seneca made damascus. L & IJ White hand tools have always been too pricey for me to collect.
.
Jerry Swinney once explained to me how the barrels makers of Motts Corners (near Ithaca), who made thousands of barrels for the Civil War effort, continued past the war into barrel steel for sporting guns. It was this skilled human resource coupled with the hydraulic water power thats exists in both Ithaca and Motts Corners that led to the founding of IGC. Before Jerry passed, I photographed most of his material. Now his edited notes are available commercially for about $300 in three volumes. I don't know if the Motts Corners material made into his books [posthumously]...glad I got a unedited copy the way I did.
.
Once again my digital camera is loaned to a friend who is taking a run at ebay...tomorrow or Saturday, when I get it back, I'll start posting some hard evidence for your files...
.
seems to me the the American Rifleman published an article on American damascus hatchetts and axes (in the 20's)
.
Rocketman, maybe I am mistaken, but wasn't Nikolas Bis from Spain? Isn't the Bis name synonymous with European damascus?
.
Rev, is that damascus picture trail your doing? It's great!...Either way, did you notice in the photo labeled "ribband" wound around a mandrel, that there is something strange. I think that winding was a factory reject that couldn't be finished...and it looks as though someone has purposly altered it to cover their tracks (as to winding and proper welding)
Posted By: PeteM Re: Damascus explained - 05/25/07 04:22 AM
Robert,

Interesting information. I was able to turn up 2 names in the 1870 census, John B Lull (or Luff) and Benjamin Losey. Both listed their occupation as gunbarrel maker. This is for the Caroline, Tompkins County, NY census track, which for all practical purposes takes in Motts Corner.

What is IGC?

For a picture of Swinney

Posted By: Robert Chambers Re: Damascus explained - 05/25/07 05:14 AM
Pete...Yes... I think the water driven forge at Motts Corners became Losey & Lull (partners) for a period before becoming a blanket factory...One of the Losey decendants is, or was a member of this bullitin board system a few years back...IGC is Ithaca Gun Co...That's a great picture of Jerry...he looks like the actor from the movie "Cocoon" in that picture...I met Jerry around 1980 and kind of modeled my research/collecting after him...he told me some wild stories...based in fact...the most unusual was shortly before he passed, I was taking photos of his hand written files, fast and furious, while Larry Shuktnect was taping voice interviews with him. During one of these interviews, Swinney claimed that the unsolved mysterious common denominator that ran completely through his body of research was...how very many of the gunsmiths, that he spent his life chronicling, had passed away from tuberculosis (with no other explanation)...
.
People think the Swinney files are the definitve work on NYS gunsmiths...but I can assure you, those files are only the tip of the iceberg...

Posted By: Dave M. Re: Damascus explained - 05/25/07 10:54 AM
How about this early Parker Twist barrel, that is mostly steel, with little iron. Thus the gray color.


Posted By: Rocketman Re: Damascus explained - 05/25/07 10:58 AM
RC - couple of things. The horseshoe nail thing was very likely done, although I've heard several versions. There would have been no special properties imparted. But, they were a good source of salvage steel.

I'd bet on the gunsmiths' demise from "tuberculosis" was actually silicosis from grinding barrels. Brit barrel makers had the same problem.

Sorry, but I don't know any details on Bis. Lot of good stuff here. Keep it up!!
Posted By: Drew Hause Re: Damascus explained - 05/25/07 12:53 PM
Dave's barrels are very interesting and I've been following the thread about them on the PGCA Forum and was waiting to add them to the PictureTrail after something definitive was decided http://www.parkergun.org/forums/forum1/3714.html
One of the articles I've found states that STEEL STAINS BLACK AND IRON WHITE/SILVER after the acid etching. Is this correct? so the brls have a LOWER steel/iron ratio than the usual damascus? Dale told Dave that he thought the brls didn't take color because of the high steel content? Apparently Parker briefly made their own damascus brls?

Mike: I would like to add your 'American Flag' brls to the PictureTrail. Please include the make, grade, and year of production. You can post the pic here or send by JPG attachment to revdoc2@cox.net and thanks!
Posted By: Drew Hause Re: Damascus explained - 05/25/07 02:04 PM
Just called Dale Edmonds, who was quite helpful. He confirmed, and apparently Dr Gaddy discussed in the 97' Double Gun Journal articles, that iron turns black and steel turns white, probably because the oxidation is removed much easier from the steel. Issue settled
Posted By: Robert Chambers Re: Damascus explained - 05/25/07 02:57 PM
DaveM...whats that patent date on the barrel flats of your Parker? It looks like Apr ?? 1876...can you tell me that exact date please?
.
sorry, I don't understand the info about mostly steel and a little iron....maybe someone can explain...
.
I thought steel was an iron alloy, made tough by forcing carbon into iron ...aren't the black lines in damascus and twist actually the carbon (martinsite) that was folded into the steel? (carbon from bone and coal)...
.
Please don't get overly technical with the answer...if you could, explain it in a way that could be understood by the thousands of uneducated men who actually made all the damascus/twist barrels. The men who made these damascus barrels knew full well that the objective was to fold and drive carbon into the iron for a stronger, tougher material that could withstand the forces and pressures involved with the end product. stahl- stand fast
.
Rocketman...the thing that gave wootz damascus its charachteristic properties was primarily the naturally occuring impurities at the location of the site where the iron ore was collected. The ironmongers smelting and carbon folding techniques may be reproducable in other parts of the world, but without the original ore source, you can't clone wootz. The thing I find interesting was the forging techniques used by the smiths who used wootz billets. Those techniques can be used on any damascus, especially scrap double shotgun barrels...and guys are...3 or 4 years back, a guy offered me (4 sale at a gun show) a ladder damascus bowie...the guy is an advanced Cattaraugus knife collector, and he named it as "ladder damascus"...I'm not interested in ladder damascus, unless it's real wootz. Far flung as it may sound, I have Albert Paley's hand crank forge from when he was a young man. I live only about 75 miles away from his studio in Rochester NY, also the home of Jerry Swinney. About 15 years ago I used it to forge two damascus swords for and with my two nephews, had I known about the wootz techniques back then, perhaps I would have used them. That was the last of my damascus/twist experiments
Posted By: Rocketman Re: Damascus explained - 05/25/07 04:36 PM
Carbon can't be mechanically driven into iron - it must "disolve" in a high heat environment. The chemical combination of iron and carbon forms an alloy we call steel (carbon content over about 0.05%). The folding and heating process exposes more area of the iron to carbon and, thus, increases the rate of absorbation. Case hardening uses the same chemical process, but doesn't expose as much of the steel to the carbon rich casing material. The hazard of mechanical introduction of carbon is that any carbon not absorbed (or contaminate material) will be included in the final metal as a very weak spot. The larger the inclusion, the more detrimental to the strength of the base metal. Removing all extranious material and arriving at a known and controled carbon content, along with avoiding cooling shrinkage voids is the holy grail of steel making. Old time craftsmen did some very amazing work considering the tools, ores, and knowledge they had to work with.

Wootz has been replicated and documented. It produces a nice blade steel, but nothing special compared to modern alloys. Of course, it would have seemed magical to anyone used to using an iron/low carbon blade. Its claim to fame was being workable at low enough forging temperatures to not burn out the naturally occuring carbon and, so, leave you with a fairly high (for the time) carbon alloy. I believe the trick is a very narrow level of mangnese (I could be wrong on that alloying component). Anyone else remember the reports on this?
Posted By: Drew Hause Re: Damascus explained - 05/25/07 04:54 PM
Some interesting infro on Wootz steel, the first by a damascus expert at Iowa State:
http://www.tms.org/pubs/journals/JOM/9809/Verhoeven-9809.html
Looks like it's vanadium and molybdenum that cause the damascene appearance of Wootz
http://met.iisc.ernet.in/~rangu/text.pdf
http://www.brisa.fi/wootz3.html
http://en.wikipedia.org/wiki/Damascus_steel

I couldn't find anything about Wootz being used for gun barrels or 'pattern welded' (what we call damascus) steel.
Posted By: Robert Chambers Re: Damascus explained - 05/25/07 05:52 PM
Rocketman...I have driven and folded carbon into mild steel more than I should have, I could have been working for money during that time. The technique is like reloading in that you're stuck adhering to a few concepts that can't be deviated from or falure will occur. For the moment, forget the 30-50 inch continous blacksmith weld that is required for one tube, and try welding the basic lap joint. Without the coal dust and fresh (unburned) ground bone in between the two pieces, to outgas carbon while welding you will get a "cold weld"...Cold welds are where most failures occur. Probaly by not removing all the scale before welding. If you adhere to time tested techniques, like applying the bone to the surface to be welded directly from your sieve, there is little chance of a bone chunk causing an inclusion the way residual scale will. Even if you apply too much bone in one spot, it simply burns off. I spent several years during and after college on the edge of anvil
Posted By: Robert Chambers Re: Damascus explained - 05/25/07 06:57 PM
WOW!!! Great wootz links...is that true taht some wootz steel can exeed 20% [Brisa link]? I find that VERY hard to believe...Wiki says 2% not 20%...and I'm shocked to see hyperbole on that wikipedia page and links.
.
One of the wiki links has an article about, what used to be called, the DSRT damascus steel reseach team...somewhere in the attic I have a picture of those guys from the 1980's...
.
Oh yeah...the one thing not covered on those pages, so perhaps it's not correct, is how damascus steel got it's name. Under the heading "Origin of the Term" it offers only one plausable explanation and cites several others, but doesn't list the long accepted version that the first carbon steel billets or cakes came from merchants who traded out of Damascus Assyria. Worldwide people began to associate those "cakes" with Damascus [the city] despite their true origin on manufacture. Much the same that we call all reciprocating saws "Sawsall" or an adjustable wrech a "Cresent Wrench", no matter who made the saw or wrench... Water pump pliers we call Channelocks.
.
Simply stated, the misnomer of damascus spread before the knowledge of true origin.
Posted By: Utah Shotgunner Re: Damascus explained - 05/25/07 11:55 PM
Drew,

I was disapointed to find that something in my gunroom corner where this gun has been stored till it gets its renovation has really turned the colors dark. Even with bright sunlight this was the best I could do.

The gun is an Ithaca Flues, Grade 1 1/2 with 28" barrels.

Thanks Mike and the pattern is nicely demonstrated in that pic. Did Ithaca call that 'American Flag' damascus? It looks alot like the 'Bernard' pattern I posted on the top of p. 3. What year production?
We'll get it added to the PictureTrail and thanks again!
Posted By: Utah Shotgunner Re: Damascus explained - 05/26/07 02:12 AM
I have generically heard it called 'American Flag' but I don't know if Ithaca used that terminology. 'Etoile' is I believe the correct name for this pattern.

Walt ????

I'll try to get a picture tomorrow when the sun is overhead. It was on the horizon when I took these pictures and I had a hard time keeping my shadow off the barrels.

Per the list on this site it was produced in 1912.

I think the additional 'stripes' in the example I posted are the reason for the 'American Flag' name but they are both versions of etoile.

Here's a late 1860s Laminated steel barrel on a nice Scott BL. I think at that time, the British laminated steel was of the highest quality. I think the finish on these barrels is the original from the Scott Factory.

Posted By: Drew Hause Re: Damascus explained - 05/26/07 04:14 PM
Very interesting Daryl. The rib is clearly twist, but the brls look like the 'Damascus Higny' or 'Damascus Leclere 3rd quality' illustrated on the Higny poster http://www.littlegun.be/arme%20belge/artisans%20identifies%20h/a%20higny%20gb.htm
Probably a 'One Iron Crolle' variant.

Revdoc, there may be a similar look, but consider that the British Laminated was one of , if not THE best, of that period. I believe it was best in the tests often reported , was it by Greener ? Now, when we think of Belgian Laminated, we take a step back, as it is usually the lowest grade offered and on the lowest grade guns. I think you will find a different quality in the British Laminated Steel. I also see laminated steel on P. Mullin guns of the same period. His guns sold for up to $300, when that would almost buy a house with servants. Of course, his guns originated in Birmingham and he finished them to the very highest level, but with no engraving.
Posted By: Drew Hause Re: Damascus explained - 05/26/07 06:38 PM
You are correct Daryl: From Dr Gaddy- "The top barrels in the famous Birmingham Proof House destructive tests in 1891 were three-iron British Laminated Steel barrels. Laminated Steel barrels were made the same way as Damascus barrels but had higher (usually 70% ) high quality steel in the composite." Unfortunately, his damascus barrel board did not include an example of 'British Laminated.' I already added that pic to the PictureTrail and will correct the caption and thanks!
Posted By: Daryl Hallquist Re: Damascus explained - 05/26/07 06:52 PM
Revdoc, we see lots of Damascus samples, laminated samples, twist samples, then take these and multiply them by the number of various sources. It all gets confusing, but to my , admittedly engineering trained mind, it would be wonderful to have an article that showed all these barrels, from all the sources, side by side. Maybe you could do an article for DGJ or similar ? Now, I don't know if writing is your interest, but maybe someone could pick up this gauntlet and do a broadranging article with good photos from each era and source.
Posted By: Drew Hause Re: Damascus explained - 05/26/07 07:38 PM
It's also clear that 'reading' the damascus pattern requires knowledge of the grade of the gun.
Thanks for the encouragement Daryl, but a. I'm not that smart yet and b. almost all the pics on the PictureTrail were 'borrowed' from internet auction sites, pics from threads on gun forums (PGCA, LCSCA, here, etc.), and pics sent to me. I have not scanned nor posted any pics from books, but probably do have some legal exposure nevertheless. I'm comfortable putting the pics up, in that I have no commercial interest in the PictureTrail, they came from the 'Public Domain,' and civil action against me would cost more than it would accomplish (I hope!)
Anyway-my intent with the PictureTrail was to provide a resource, and thanks to Dave Miles and others, I'm most thankful the some of Dr Gaddy's contributions were not lost. Hopefully, Dave will add some of these threads to the FAQ section (and we've e-mailed about that.)

REB87...What? ...AF touch mark on Liege barrels...marked S Sutherland...on a George Ferriss patent...??? Is that correct? It is rumored that George went to France...possibly something to do with Ferris wheel...but that is the wrong George Ferris..
.
the George Ferriss that was issued pat # 119834 is spelled with double s...Ferris (wheel) is single s
.
It's not that I don't believe you, it's just that the Belgians would rather leave the name off of the gun, than pay royalties to some New York Yankee.
.
A couple of years back on this bullitin board system, several members chatted it up over some Belgian made double that was made on Lefever patents...I say "bull"! Either that gun does not exist, or perhaps it's a converted Belgian muzzleloader from back in the days when Lefever was converting muzzle loaders into breech loaders like the Barber and Lefevers..
.
I can see the patent Ferriss breech on your barrels, but with an August Francotte touchmark, I guess it's possible, as Francotte seemed to be one of the few Liege makers that paid royalties rather than just make an improvement on other designs ,giving them a means of circumventing the original patent,like the Deforney Holland ejector system.
.
If your gun is in fact made on a George Ferriss patent, it belongs in a museum. If it's originally made that way ,and not converted, with ANY Ferriss markings, it should probably be in the Liege Arms Museum...so...I'm guessing it's a converted gun or a Belgian design rip-off (post 1871) only because the gun seems to be too good (interesting) to be true...which is it?
.
Utah...your Flues 1 1/2 barrels are exactly the "stars and stripes" pattern known as American Flag Damascus...American Flag Bunting Damascus would have been a more accurate description, but since everyone knew what bunting was back then, there was no need to include the word. Bunting was popular back then, it's relatively rare today...

Here are some more pics of said gun.
It is marked "Fine Laminated Steel S Sutherland" on the rib.

It is marked "GH Ferriss Patent" on the left plate, "October 10 1876" on the right.

OK ...it's not the patent breech that I first thought, but wow, that gun still belongs on a museum...I thought you had an example of the cap lock breech loader as can be seen in patent 119834...Geo Ferriss had many patents, but none that I have are on on that date...Rather than sway anyones interpretation of your photos along with the proofs and touchmarks, I will just show the two shotgun patents that I have and hopefully many observant eyes will result in an accurate understanding of this extremely unusual double...This gun deserves it's own thread. Even if it stalls for months 'til the right bits of Belgian data surface..That MG brevete number on the action flats will probably corresponde to that patent date. Maybe that patent will answer some questions. More likely, it'll create more questions...I'll try to run it down..
.
I can't help but wonder about the Belgian connection...Did George try to market his design abroad, like Browning and Newton did, or was he already connected to the Belgians because of his ordnance designs?

In my opinion damascus steel, as with all other alloys, has never reached the degree of sophisication as it has in recent decades [except for maybe the high art of the Prince Phillip, Remington, or Terrell type damascus]...Well here are some leads for anyones American damascus files...
.
In 1937, there was a company in Rockford Ill. by the name of Damascus Steel Product Corporation. They held a patent for a meat cleaver, but that couldn't have been their only product...Of course 1937 is very late for damascus barrels...
.
In 1856, John Nevill and Lemuel Curtis recieved a patent for simplified damascus substitute [alloy] assigned to J P Farrar of the "Damascus Steel Manufacturing Company"...kind of early for the golden age of double shotgun production, but none the less, another lead.

Posted By: Robert Chambers Re: Damascus explained - 05/28/07 02:33 PM
Thanks...I didn't have the Mannesmann patent...Bradley and Eose didn't have drawings to post pics of...but I really want to thank you for getting the ball rolling on American made damascus. In the past, damascus experts rejected any notion that other than "uncle Bob" (or someone) at Ithaca, damascus simply was not produced in America. In fact damascus steel, the earliest available form of carbon steel, was produced to some degree, in nearly every industrial nation.The information you've posted points to the the real truth about damascus actually being rolled rather than forged since c1880's. In the past at this BBS system, that kind of information, that flies in the face of common long held beliefs, could have got you a gang bashing here. Everyone took Greeners forging information and used it as a corner stone. I seriously doubt that any of the post 1890 barrels were forged. I'm guessing that post 1890 barrels make up 95% of the damascus doubles out there. It's been a long time since I read the Eose patent, but I think rolling damascus weighed heavy into it, and that was 1863..
.
It's hard to believe that most of these guys actually think that a team of 3 Belgian Elves, working for Lochet-Hebron, worked for days hand forging each tube, as pictured in Greener's book. Yeah right! Then they added shipping to America where the workers at Ithaca Gun Co, knit the barrels together, built a gun around them, the sold it for $40 retail.
.
Most of damascus barrels that we see were machine wound onto a negative draft mandrel, and rolled off the assembly line like hotcakes. [no pun intended...wootz cakes] Probably some of the, stubborn about tradition, Brits, continued to hand forge a little later but it wasn't Greener.
.
Pete, one last thing...about your last post...it's made up of highly concentrated data that leads directly to volumes more information. The problem is, all the hours of work it takes to construct such a posting is lost once the thread dies. Had you printed it, photographed it and posted the image, readers could save your entire post as 1 image. This way, your hard earned posting would never die and have a better chance of getting into the hands of the next researcher. With all the time you've already spent, I don't feel right about asking for more. I was just hoping that some future researcher could stand on your shoulders for a better look....

I don't have much trouble understanding how the "irons" or composite rods could be sized, thinned, stretched between rolls. How precisely are the edge welds achieved once the spiral is on the "negative draft mandrel"? Is there an unstated suggestion here that somewhere in the northeastern U.S. existed a powered hammer akin to a predecessor of the Rotoforger which Ithaca used on the steel billets for the 37. Different ends here I admit. If the output of Belgian hammer jockies wasn't up to he demand, where's the equipment or the record of the equipment that replaced them? The patent drwg of the faux applique machine is interesting. Where's the drwg of a machine that could make the real McCoy?

I've followed this thread with some interest. I would like to suggest that anyone that is interested in damascus steel try to get hold of a copy of "Damascus Steel" by Manfred Sachse. I am unaware of any book that covers the subject more throughly than this one. The copy that I have belonged to Oscar Gaddy and I purchased it from his wife after he passed away.

I'm not sure whether it is possible to scan and post some of the pictures that are in the book but I believe that the information in this book may clear up some of the questions about damascus manufacture.
Posted By: Robert Chambers Re: Damascus explained - 05/28/07 10:41 PM
Rabbit, I wouldn't mix in hammer forging just yet...and if you really want to understand barrel damascus, try to avoid the overwhelming volumes of blade technology {which is mostly forged}...the reason the mandrel had negative draft (slightly tapered) was so it could be removed easily.
.
Reb87...about your Spencer...there are several different names associated with that design...The "Norwich" and Torkelson are just two...hopefully someone, who lives near Norwich or Worcester Connecticut, will take the time to sort out the evolution of the Norwich gun...somewhere I have a Torkelson that is very similar to your Spencer..seems To me that Torkelson was associated with Iver Johnson, John Lovell, Andrew Fryberg, and Martin Bye among others. The evolution of the Norwich or Worcester gun has yet to be roughed out, let alone examined closely...

Posted By: rabbit Re: Damascus explained - 05/29/07 01:16 AM
Bob, I can't imagine why the edge welding method would go out the window simply because the master and his gang aren't fast enuf. Hammers can't be ganged, made into shaped swages, powered by hydraulic ram? How precisely would these strips be welded if not by pressure? Surely you're not suggesting heliarc in 1863. As for "negative" draft, if you had been around patternmaking or toolmaking for any molding or casting trade, you'd know that there is just draft (taper). Never heard the word negative used in the several years I spent around tooling for hand-laid fiberglass and vacuum-formed plastics. The only context I can think for the concept of positive and negative is in the relationship of plug to tool to final product.

jack
Posted By: Robert Chambers Re: Damascus explained - 05/29/07 02:46 AM
Edge welding didn't go out the window...you can't make damascus or twist tubes without edge welding...and whats all the talk about rotary hammers and heliarc? I guess I wasn't specific enough when I said don't mix in "hammer forging" referring to Ithaca's rotary forge that's 50 years later than the period of interest here. Hydraulic rams? trip hammers never had hydraulic rams? You've lost me...
.
Edge welding can be easily achieved with heat, pressure, and borax...impact is not necessary, it's just another way of delivering pressure...

I didn't use either the word "impact" or "triphammer", Bob. In fact if you look closely, you'll see that I used the word "pressure" which can be applied, as you say, by the momentus momentarius or the squeezus sustainus ha ha ha ha. Indeed the RotoForger may not be in the line of descent from whatever method and mechanism you're suggesting. What is? Hollow ram on the end of the mandrel that bucks up the edges of the spiral. Cmon, what ARE YOU talking about (in specifics of course)?

Jack,

Good questions. From my very limited understanding in reading some of Claude Gaier's work. The relationship between the US and Belgium can be traced back to the American Revolution. (Belgian Gunmaking and American History by Gaier.) Gaier notes the huge volume of firearms destined for American shores after the revolution began. We are aware that during the American Civil war there were official and some not so official observers from Europe. One of the lessons that the Belgians took home was the impact of mechanization in the making of firearms. Several companies took this to heart. Gaier points to FN and Pieper as taking up the "new way" of using factories and machines. ("Quatre siècles d'armurerie liégeoise" by Gaier. Also "Les hommes, les armes et les machines du Chevalier Pieper & Cie 1859-1957" by Michel Druart.) This was stepped up over time. We like to think of a Belgian cottage industry in sporting firearms. This was also true. Gaier notes the there was almost a class hatred between the cottage firearm maker and the factory worker.

I stated all that for a reason. I have pictures of both methods. The end of damascus production in any reasonable volume was some time in the 1920's.

Since the formation of the EU all patents are now under one authority. I have tried to use their web search engine to find exactly the sort of patents you are asking about. Unfortunately, my attempts are futile and frustrating. There is something I am not getting, but the results are always worthless. I guess, I should start trying to pry that information out of the American patents. You are correct, some one was making these machines. If we can identify an American source and date it, we are closer to understanding.

Also, Robert's caution about damascus for blades is correct. It is a different product. Which is why I did not attempt to track that Rochford reference above.

Rabbit, There were damascus barrel makers in America, but very few...relatively none, when compared to Europe and England...during the hey-day of American double production it seems as though not one American damascus maker could not compete with the Europeans makers in both numbers or cost..American makers chose the fluid steel alternative, as the Europeans eventually did.

Didn't all heavy industry, in Liege, crash during WWI or WWII, or was Liege spared?

Although I have no saved proof to offer, I was told, that after WW II, a few Val Trumpia gunsmiths (desparate consumers of Liege forgings) bought out Manufacture Liegeois's drop forges, dies, or fixtures. Shortly afterwards, the Val Trumpia double shotgun production numbers climbed like never before while the Liege smiths re-tooled.
.
If the Liege sporting gun industry wasn't interrupted during WW II, why then would the Italian gunsmiths be so desparate as to buy their tooling?

Pete...If you could narrow it down at the US patent office, there will probably be a European classification number to cross reference...But I won't waste my time on such a pursuit...I've been searching for years for any related patent to the venerable Belding & Mull without success. There are more dispensing and metering threads than I can view. The machinery patents that you seek could be buried in any number of classifications with all the various sub-catagories or threads. Could be in a winding thread, could be in a seam welding thread, or it could be in a manufacturing process thread. It's probably in several threads. But who knows...you might get lucky by patent searching the names of known makers of damascus/twist steel. If that doesn't work, it's going to be hard row to hoe. Maybe Gaier's book will offer some search names...Bob

I think part of this has to do with profitability. If you are going to start making barrels, then you will be looking to the rifle and hand gun markets as well. From at least 1890 to 1920's American policy implemented a series of tariffs on imported goods. So, the Belgians, English and German barrel makers had to be offering a unique / affordable product. In addition, makers like Heuse had American agents competing for business here.

Quote:

From the little research I have done. After WWI there was a great outcry about German atrocities in Belgium, mainly forced labor. I do not believe the factories themselves were damaged. After WWII the a lot of the heavy industry of Belgium was damaged by Allied bombing and the ground war that ensued. So there had to be a major rebuilding effort.

Quote:

The Italians were in even worse shape after the war. A lot of damage was done during the German retreat and again the bombing campaign.

Hopefully, some one with more detailed knowledge of this period will respond.

Pete...I know nothing of the import tariffs but this....and I am reluctant say this, as it will surely be interpreted as "fighting words" by some...but here goes...
.
Back in the 19teens an immigrant Austrian apprenticed gunsmith by the name of Fred Adolph of Genoa and Rochester New York imported Austrian and other high grade guns into America. He advertised that he made the guns to cover the fact that he was in fact importing the guns in pieces in order to skirt the import tariffs. Because of the Fred Adolph stories, and the fact that his close personal friend, Chas Newton (a lawyer and owner of Newton Rifle Corp.), also tried to follow suit as a barrel importer for his own factory, I think barrels (and parts) were exempt from any stiff tariffs...I can elaborate on the Newton barrel importing effort if you would like.
.
As for the Italians being heavily damaged, maybe the Val Trumpia region was spared becuase of it's location away from the shores, way up north. By the way...I was told that as a general rule (not always), you can locate family origins by the last vowel. Families whose name ends in "o" or "a" are from sothern Italy (traditionally)...Family names that end in "i" are from the north, like Bernadelli, Zanotti, and Beschi...just in general though

The tariffs started out as a protectist move for the American farmer. They had the opposite effect. McKinley gained national recognition with his 1890 tariff. The tariff wars in Congress raged for almost 30 years. The actual tariff rates and those items on the list changed back and forth. I believe that the barrel tubes incurred 1 rate, while finished barrels a higher rate. One of Wilson's campaign planks was to do away with the tariffs, which to a certain extent he did.

A Puck cartoon attributing the Republican defeat to the McKinley Tariff. With McKinley as Napoleon leading his troops out of Russia.


I am surprised there aren't more stories about "black market" gun parts. Yes, what more do you have about Newton.

Pete
Posted By: Robert Chambers Re: Damascus explained - 05/29/07 07:16 PM
I like to think that I have the most of the big picture when it comes to the the evolution of the Newton barrels. I've been a long time wildcatter, shooting a .220 Dean (blown out swift), .256 Sabad (Vom Hofe), .30 Reis, .256 Newton, and I recently acquired a ".30 Nedgley" barrel by Neidner Rifle Corp. but I haven't started on it yet. The area where I live is wildcat country, maybe because of Newton's influence on local interests, but whatever the reason, Western New York has been the home of well over a dozen wildcats. Most notably the 25.06 (.25 Newton to .25 Neidner to 25.06 Rem) .338 Winchester (.33 Newton with a belt) and 6.5 06 (.256 Newton)
.
That being said, it's important to note that Newton abandoned the .25 caliber bullet for the 6.5, not because of the liability of the .25 getting into the wrong guns as some have suggested, but because Mauser, Steyr, and Sauer where already tooled for 6.5. ... WW I, and the tremors that led up to it, created enough difficulties, that ultimately Newton changed horses mid-stream and abandoned importation from Mauser and Sauer, and just imported a rifling machine from Steyr (in 6.5). The machine arrived in several shipments of parts and upon assembly, no one could get to work correctly. In a letter to Newtons investors, he explained that one of his large expenses was the high cost of paying his "model maker" (Emil Flues) to work exclusively trying to make the machine work. After months of wrestling with it, Newton brought in a barrel expert (Harry Pope) to work out the remaining kinks...which he did...and to this day, if you know what your looking for, you can still buy a Newton rifle, hand finished by Flues with Pope rifling.
Posted By: Robert Chambers Re: Damascus explained - 05/29/07 07:46 PM
Oh yeah... I have the remains of Harry O Dean's files and unpublished manuscripts...He was a gun writer for several gun magazines after WW II ...and big Newton enthusiast/researcher/writer and for what ever the reason he was also photographer for Marlin, Ithaca, Savage Fox, Crossman and others. I got the manuscripts and negatives, but unfortunately all the factory photos were stolen by Joe Reece and the "high tech burglary gang" along with Charles Newton's personal Austrian drilling marked Fred Adolph, Genoa New York. The gun can't be missed as it has a gold C N cypher where the top lever should be. There's a picture of the gun in his files. They stole Harry's entire collection from his widow a few weeks after he died.

Many thanks to those of you who suggested Keith Kearcher to my younger brother. His Greener G60 (he found the grade marking not on the trigger guard but on the fore end iron) just back today from having had his barrels refinished, sighting ivory bead replaced, ebony diamond insterts restored, stock glass bedded and action tightened up. Keith measured the minumum bore wall thickness at .035. I think this one will be a good shooter for many years to come.

I'll leave it to my brother to post more photos, here is a photo of his damascus. Keith turned the gun around in record time (under 4 weeks). I think these barrels are the highly prized three iron. My brother just got the Greener book and wonders if these are the silver, stub, or other version of Greener's damascus.

Kearcher would certainly know, but they look like high grade Bernard. When was the Greener made?

Thanks. Another member based on the SN dated it to the late 1880s.

Well... turn of the century Parker catalogs state their damascus is hammered and turned, which doesn't support my belief that most skelp barrels were rolled onto the mandrel rather than hammered inch by inch. Of course the catalog makes no attempt to clarify that they don't actually make the barrels, they simply purchase them from various sources (on a far away continent), which makes the process way beyond their control. So I'm not buying it...but here is the data for anyone wishing to add to their damascus files.





Posted By: Drew Hause Re: Damascus explained - 06/01/07 05:39 PM
Robert- that's where the quote on the 'Damascus Barrels' PictureTrail album intro page originated
"These fine barrels are not worked and twisted so neatly and nicely that they may look beautiful alone, but rather for the reason that greatest lightness, combined with greatest durability, may be produced." (from the 1899 Parker Bros. catalog)

I'd like to add a few more interesting/meaningful quotations if anyone has a good one.

The white is iron and the dark is steel. Did we not decide it was opposite just the other day?
Posted By: Drew Hause Re: Damascus explained - 06/01/07 08:56 PM
Yes, the Parker catalog was one of the sources of my original confusion-but per other sources, Dale Edmonds, and Dr Gaddy- it's IRON turns BLACK and STEEL turns WHITE.
Posted By: dbadcraig Re: Damascus explained - 06/01/07 11:42 PM
So does it stand to reason that the barrels with the most steel (white swirl) in them are the superior barrels and thus, the percentage of white the barrel, a fair indication of the quality of a damascus barrel; or is there anything good about having iron in a barrel?

It would appear that in the Greener photo I posted above, there is a lot of steel in those barrels (is this an example of the famous 70% Birmingham damascus...actually it looks like it might have a bit more than 70% white swirl)?
Posted By: Drew Hause Re: Damascus explained - 06/02/07 12:10 AM
On p. 380 of 'L.C. Smith "The Legend Lives"', the damascus barrels as graded by Hunter Arms are shown, and the steel % described as follows:
English Stub Twist- 52%
Good Two Rod Damascus- 60%
Good Four Stripe Chain Damascus- 60%
Fine Three Rod Damascus- 67%
Finest Three Rod Damascus- 70%
Choice Three Rod Herring Bone Pattern- 70%

The Greener brls may be 'Bernard', which was available in several grades. Please see Ferdinand Drissen's 1897-1898 price sheet:

More notes on American damascus if anyone is still interested
.
In early 1864, Walter Baker of Ilion NY (very near Lisle NY. then home of W H Baker, but I don't know if they're related)recieved a patent for a trip hammer that was specially designed for making gun barrels (patent 41669)...one of the reasons I'm mentioning this patent, is to show the tail end of hammering, and that by the late 1860's the shotgun industry had already adopted the higher volume production techniques. I am hoping that the thread contributor with access to the Tompkins County directory will cross check the name of Walter Baker, to see if he appears anywhere near Motts Corners (prior to 1863). I'll check Jerry Swinney's files for the same.
.
In 1865, Ethan Allen recieved a patent for twisting, winding, and welding damascus shotgun barrels. The patent, 48249, goes into details of the process. One the witnesses is Sullivan Forehand. Then, exactly one year later Ethan recieved another patent for soldering the tubes together through internal flaming. Again Sullivan Forehand was a witness. Ethan Allen resided in Worcester Mass at the time of both patents
.
In 1869, a patent was issued to Selah Hiler of Harlem NY for improvement in the manufacture of gun barrels in which he states that "sucessive rolling operations" is the "usual" (manufacturing process) (by 1869). This is not the only reference to the rolling of damascus shotgun barrels in the historical record, but it is the last time I will spend trying to convince the guys still holding onto the thousands of hammering elves concept. (samurai barrels)


.
Lastly, although this is not for American made damascus, I thought that you might be interested to know that winding was not the only technique used for making damascus barrels. In 1892, Franz Meixner of Austria recieved a U.S. patent for a new departure in damascus barrel making that involves many cones stacked around the mandrel. This technique offers a much higher surface to surface area for welding, and theoretically offers a far stronger damascus barrel than anything seen before. (US pat 477763)


I hope I'm adding to the understanding and not inadvertantly adding to the misunderstandings involved with damascus steel shotgun barrels...Please note how the great missing chapter of American double evolution keeps cropping up ...Worcester

Here's a copy of Ethan Allen's damascus patent. I decided to post it only because it's a very interesting read. Please say if this data is overly technical.
Posted By: PeteM Re: Damascus explained - 06/04/07 02:56 PM
Walter Baker is 33 in 1870. Born in England and works in the armory. He lives in German Flats, NY with his wife and 4 children.

William H Baker is 44 in 1880. He lives in Manlius, NY with his wife and 7 childern, the youngest a boy named Walter. William H Baker is listed as being born in NY.

Of course, I could have these 2 names very confused...

Worcester is interesting. It is the home of the Bay State gun company which was later purchased by Hopkins & Allen. Bay State used several patents by W.H. Davenport, who later sold single barrel shotguns under his own name.

By the way. Nice work finding the trip hammer patent.

Drew,

I like the price list. I have seen similiar, but never so complete.

Pete,
You sure nailed it down at light speed. With W H and Walter being only a year apart and born on different continents, I guess it's highly unlikely they're related. Also, Walter's being born in England, makes it unlikley that he ever worked for the dyed in the wool outfit later known as Losey and Lull (in Motts Corners) Thank you Bob

After all this is your topic...and you have taught me 10X more about damascus barrels than anyone...I was hoping that you would say whether or not I'm adding to the understanding or whether I'm being overly technical. I figured that the biggest contributions I could add, is to dispell the erred concepts that damascus was never produced in America and the samurai barrel notion. I hope you see this data as positive advances in the understanding of damascus barrels. If not, just say so and I won't contribute further...Bob Chambers

Unfortunately, in Medicine anyway, what passes as 'truth' usually changes every few years Hard to argue with copies of patents however! And your, and Pete's, contributions, and every pic posted with a different damascus pattern, have been extremely valuable.
Posted By: Daryl Hallquist Re: Damascus explained - 06/04/07 06:26 PM
I believe the book, Espingarda Perfeyta or The Perfect Gun, written in 1718 shows the "cone" method of making Damascus barrels. Of course, not called Damascus then. Interesting a patent for something similar over 150 years later.

Do you have a patent number for the Selah Hiler patent? I want to read it. Rolling mills became essential for the gun industry. Curious to see if the patent talks about low / high carbon etc.

Your information is very valuable. Do not stop.

Pete,
Thanks, that means a lot more coming from top quality contributors/researchers like you and Rev. I really admire the way that Rev leaves records (picuretrail) to be added to at any time. His data collection will probably outlive all of us.
.
The reason I didn't post the Hiler patent (34961)is because his patent marks the beginning of decarburized/compressed steel shotgun barrels (1869)...it would be another 20 years before the industry really began to utilize this technology. More to follow...
Posted By: Robert Chambers Re: Damascus explained - 06/05/07 01:24 PM
There seems to be several patents and many records of barrel makers in New York City in the mid to late 1800's. It must have been a sort of "hub" for barrels makers and iron workers.
.
I don't know what to say exacly so again I'll just blurt it out...3 years ago, at this website, I would have been tarred, feathered, and run out of town on a rail for suggesting that not all damascus guns have samurai barrels (in fact relatively few)...but now that the age of ignorance has passed, I have become a fisherman of sorts. I'll explain,...for example...now that Ethan Allen's patent has been posted, I'm waiting for someone to come forward with an early Allen shotgun, where there can be no doubt that it is actually American made damascus....especially if the barrels are dovetailed together completely down the barrel...The other maker to watch for American damascus is Wesson, I suspect his barrels were sometimes American made but I have no evidence yet. Once we learn how to recognize Allen damascus, hopefully we will be able to recognize it if it appears on other guns...thanks again...Bob Chambers
Posted By: Robert Chambers Re: Damascus explained - 06/05/07 01:34 PM
Pete,
If your interested in the demise of damascus, you may want to read 1005115 (1911)...it was issued to Franz Hatlanek of Kladno Austria...Kladno is also the home of Poldi steel including "anti-corro steel" but I have not yet connected Hatlanek and Poldi except for proximity and trade. At the very least, they where competitors if not associates. My guess is that Hatlanek was an employee at/for Poldi. I'm assuming Poldi is also someones last name and not just the name of that large Austro-Hungarian steel producer located in Kladno.
.
also the exclusive horse shoe nail period was 1800 - 1825, after that there were more variations to choose
.
true hand hammered damascus (stub/twist/skelp/mingled), like Rigby damascus (Dublin), became economically unfeasable in the percussion era. If someone thinks they have a hammered damascus gun, it had better be percussion or a converted percussion (like Barber & Lefever)...past that, you better have documentation that shows that maker (or makers supplier) was still hammering so late. The only breech loading exceptions that I have seen had high relief Rigby damascus recievers and rolled damascus barrels. Both were Irish guns.
.
True Damascus steel (capital D) better known as "wootz" actually originated in Kurdistan. At least that seems to be the general consensus. Perhaps Rev already stated that, and I'm re-hashing old ground.

I have two, and have had several other Ethan Allen trapdoor shotguns. Their Damascus varied by grade. In 1869 they offered Fine Stub Twist on their $100 gun, and Fine Laminated on their $150 gun. A special gun, not serial numbered , was made for G.H. Coates, the foreman of the Allen factory. It's barrels are marked Finest Laminated. These guns are interesting in that the bottom half of the breech of the gun, approximately 2 1/2" wide x 3" long x 1" deep, appears to be made from the same piece of "steel" as the barrels.
Posted By: PeteM Re: Damascus explained - 06/05/07 07:16 PM
The Allen in Hopkins & Allen was Charles H. Allen. Hopkins & Allen was formed in 1868 in Norwich, Conn.

Ethan Allen was from Massachusetts. He was born in 1806 and died in 1871.

Reb87 has brought up a very important point. Ideally an Allen trapdoor double will surface. the words, Patented Nov. 25 1890 has been recorded on Hopkins and Allen shotguns. That date correspondes to patent 441395, issued to Martin Bye and assigned to Sullivan Forehand. Both patent and shotgun were toplevers. Allen died (1871) only 6 years after the trapdoor patent was issued. His successors , Forehand being one of them, continued on with the Worcester gun trade after his death. It would be very hard to concieve that Forehand and the others produced no double guns from 1871 to 1890...surely there were many, but again we are into lost chapter of American double evolution...the Worcester gun...I guess that makes all Worcester doubles suspect, especially the early toplevers (pre1890)...Wish I could be more definitive but I never got around to buying the book by Harold Mouillesseaux about Ethan Allen...maybe that book will yield some information or clues, if anyone has it...I'll take a picture of Torkelson damascus barrels and post it, but I think that's way too late.

Posted By: Robert Chambers Re: Damascus explained - 06/06/07 03:25 AM
One of the Irish doubles with the high relief Rigby damascus recievers, that I mentioned in an earlier post, is a Joseph Harkom, 12ga, round action,front action hammergun, Jones rotary underlever, straight grip, with what looked like rolled damascus barrels to me. I think the gun now lives somewhere near Syracuse NY. So for good examples of late hand hammered Rigby damascus take a look at the Harkom rotary underlever reciever. There is little to no engraving, but instead the action is 100% high relief damascus.
.
I once bought a caplock T. Mortimer, 20ga, fully engraved, str grip double, with high relief silver damascus barrels and raised proofmark silver soft plugs on top from Dutchman Woodworks for $300...I loved it for a few years and let it go for $375 to a friend from Batavia NY...wish I hadn't...I never knew much about that gun or the origin of the damascus. The main reason I bought it was because it was the only piece of silver damascus I had ever seen.
Posted By: C. Kofoed Re: Damascus explained - 06/06/07 03:26 AM
Unfortunatley, I think the Liege museum is still closed. They have been "refurbishing" it for several years.

Krupp "Nirosta" (patent 1912) is another stainless that may have originated at Poldi. At that time in the company's history, Krupp had enough money to buy anything he wanted like patents and whole armorplate companies simply for the technology.

Early on, A. Krupp's pride and joy was his huge steam hammer "Fritz". By 1864 he had 7000 men using it to make "fluss stahl" barrels amoung other things; by 1871, he had 10,000 men. When "Fritz" failed in the mid 1880's, Alfred Krupp installed a 5000-ton hydrulic press for his now 20,000-man workforce. It was no different in Liege, Gardone, Birmingham, Suhl or New Haven; the industrial revolution had hit gunmaking by the 1860s(It all started with Watt's engine in 1782 and was going "full-steam" in England by 1800). The British need us too, and came to America for mass-production rifle-making machinery from Robins and Lawrence of Windsor, Vermont and Ames Mfg. Co., Chicopee Falls, Mass. With it, they to equiped their arsenal at Enfield. There, by 1858, they were turning out 2,000 rifles a week. (Tate, 1997). Greener, himself, mentions using "17 different machines to shape stocks".

I could'nt help but think by the mid 1860's Damascus barrels were at least partially machine-made--ultimately, a dollar is a dollar; machines were cheaper and more efficient, then as now.

It still takes the touch of human hands to make a good gun, however, now as then!
Posted By: Robert Chambers Re: Damascus explained - 06/10/07 06:29 PM
Sorry for the late addition...this may help someone identify their damascus barrels maker.
.
In 1894 a British patent was issued to Eugene Joris of Fraipont Belgium, who lists himself as a "manufacturer", seeking a patent for a new metheod of manufacturing damascus tubes. He prefaces his patent by stating that "damascus tubes in use up to the present time consists in rolling the steel band into a spiral".
His new patent damascus is comprised of 16 longutudinal rods, without a mandrel, that can be welded by rolling in a press or by hand hammering.
.
the key info is that another damascus craftsmen has been identified including city of origin..the patent number is 1981, it was issued in 1894....And yes, there were still a few stragglers interested in hand hammering well into the 1890's... NOTE...Not to be confused with Belgian gunmaker Jean Joiris of Wandre Belgium...jor not joir
Posted By: Robert Chambers Re: Damascus explained - 06/11/07 03:44 AM
Rocketman,
To quote yourself "Carbon can't be mechanically driven into iron - it must "disolve" in a high heat environment."

I know what you mean, the carbon must be absorbed on a molecular level, but when you're standing there with the tongs in one hand and a hammer in the other, molecular injection is not the model the old timers had you thinkin' about. You layer and sometimes folded (rarely) the carbon (ground bone and charcoal dust) into your separate bars. After welding with heat and hammer, the single massive bar is twisted hot with borax and the remaining slag is driven out using heat and hammer.
Well at least this is the technique I was taught or maybe my perception of what I was taught.(30 yrs ago)
.
Well I could sense that you weren't buying that concept, and it's easy to see why...I'm not in disagreement with you, I just didn't want you to go away thinking that I had my ass on completely backwards...so in defense of erred (maybe) concept, I would like to post his page from a book published by Johns Hopkins University press (1960's)


Maybe you can't mechanically drive carbon into steel, but we didn't know that, so we went ahead and did it anyway...My blacksmithing experiments, unlike my case color experiments, rarely resulted in defeat. Bob Chambers
.
P.S. except for the common beginners mistake of forging the billet way too wide, I can think of no other reason to make longitudinal folds. The longitudinal folding technique allows the smith to concentrate the high carbon area at the cutting edge of the blade (in the crease). Wrong or right, that was the idea. Keep in mind that I learned farm implement smithing, the only kind still in existence in these parts. 100+ years ago, this technique was used when making implement blades out of regular mild steel. Nowadays most steel choppers just run over the cutting edge with some hardface welding rod and grind it sharp, the technology has changed, but the idea is the same.
Posted By: Rocketman Re: Damascus explained - 06/11/07 06:12 PM
RC - I have no issue with what you do/did at the forge, only how you describe it. To be effective, the carbon must be exposed to the steel at high enough temperature to chemically combine. By repeated heating, folding, and hammering, you "kneeded" the steel much as one "kneeds" bread dough to mix in a little extra flour. By making the steel flow in the heating, hammering, and welding steps, you exposed a lot of new surfaces to the extra carbon you added. This increased the amount of steel exposed to extra carbon and allowed for a much more uniform alloy. A ten pound bar of iron would need less than a tenth of a pound of carbon added (absorbed) to become a serious high carbon alloy. The trick is, of course, to carbon without burning out the carbon in the surfaces exposed to air.

I have no reservations as to admiration of blacksmithing skills.

Thanks, I knew we were on the same page. I was thinkin'...that you were thinkin'...that I wasted all that time, barkin' up the wrong tree, rather than teaching myself damascus steel making.

Did you see that new damascus solid rods are available as raw material for gun barrels and jewelry manufacture(?) directly bubble wrapped from Bombay, India? Some say wootz originially came from India. I've also heard or read Sri Lanca (Ceylon), Kurdistan, Persia, Assyria (nearby to Damascus City), and even Sweden. Is Kurdistan the general consensus?

Posted By: Rocketman Re: Damascus explained - 06/11/07 08:24 PM
I doubt there is any hope of proving where Wootz originalted. It would have been widely traded as it was highly desirable stuff.

I'd bet on the re-emergence of barrel damascus - only highly automated.

STILL working on the PictureTrail. Have found 3 excellent examples showing 2-, 3-, and 4-Iron Crolle patterns in which you can clearly count the number of 'scrolls' between the 'ribband' weld lines. This works fairly well in "Turkish" and "Horseshoe" Crolle patterns, not so well in others as the weld lines can be difficult to distinguish.

The 'ribband' weld lines are seen clearly in this 'Black and White' refinished Two Iron Crolle pattern. Within the weld is one 'scroll', representing one 'iron' or 'blade', and 1/2 of the adjacent 'iron' on each side. F Grade Lefever:



Three Iron Crolle has two full scrolls with a 1/2 scroll on each side. LC Smith 'Finest Damascus':



Four Iron Crolle:
Three full scrolls between two 1/2 scrolls within the ribband weld lines. Baker Presentation Grade:

VERY nice Casey C. The second and third are both 'Two Iron Crolle'; a full scroll between two 1/2 scrolls within the ribband weld lines. The third has thicker lines and a more open scroll that has been called 'Horseshoe'
The beautiful Ithaca is 'Stars and Stripes' or 'American Flag Bunting'-stars within the scrolls-and I'll be adding that pic to the PictureTrail and thanks!

"English workman Thomas Smith... 1822.. Harper's Ferry armory... His blows upon a twisted barrel (to quote Mr A.H. Waters) followed each other like the taps of a woodpecker, scarcely leaving a square without the marks of his copper hammer."


This is from "Fire-Arms Manufacture 1880", U.S. Department of Interior, Census Office. They are discussing barrels - Truing or Straightening of Barrels. I thought the reference to a "twisted barrel" significant.

Robert,
Look for water, railroad lines, steel producers and / or armories....

More sources of American made, hand hammered, twist/skelp barrels are...any guns made by, or with barrels made by, A V Sill of Buffalo NY, Miller brothers of Rochester NY, Losey & Lull of Mott's Corners NY. but mostly Levi Coon of Ithaca NY. The site, where in 1883, W H Baker established Baker Manufacturing>Ithaca Gun Works>Ithaca Gun Company, is a particular site on Fall Creek known as "Triphammer Falls". This site was once he site of (gun barrel maker) Levi Coon's triphammer untill about 1830. This site had been named after Conn's triphammer. By 1834, Levi had re-established himself at Mott's Corners only about 3 miles east. Coon's barrel making continued on, later to become Losey & Lull, until one by one most of their skilled employees went over to work for Baker at the very site Coon had left 50 years beforehand, Triphammer Falls. But it was not the loss of the skilled labor pool that ended Losey & Lull's barrel making business, it was Remingtons new "Cast Steel" barrels being manufactured only about 60 to the miles north.

Perhaps I pay not enough attention....where are the weld seams/lines on the "laminated" tubes? Am I just not looking hard enough or are they done by a slightly different process?

Posted By: Drew Hause Re: Damascus explained - 06/17/07 03:41 AM
Mark: I've not been able to find anything which explains the difference between 'Laminated' and 'Crolle', but Dr Gaddy said the production method was similar. And I can't identify the ribband weld lines either- which might explain why Three Iron British Laminated Steel was the winner of the 1891 Birmingham Proof House Trial.
Posted By: Drew Hause Re: Damascus explained - 06/17/07 03:55 AM
Glad this came up and here we go:
"Damascus or twist-steel barrels are made by layering alternate strips of steel and iron then welding them together. The strips are then twisted until they resembled a screw, three of these wound strips are then welded together, wound around a steel mandrel, then welded and hammered into a barrel tube. Laminated steel barrels are a bit different. They start with a ball of steel and iron that is then hammered into long strips and twisted, then, like their Damascus cousin, wound around a mandrel, welded and hammered into a barrel tube."

The description the revdocdrew just gave us has only one subtile difference in it between the two kinds. Starting from a ball or starting from strips. I believe we need to see someone make some of these patterns to grasp the methods of manufacture. Thanks to all who posted here! Great subject! David
Posted By: PeteM Re: Damascus explained - 06/18/07 12:34 AM
That is a very good definition. Just remember that is a gunmakers definition. A blade maker would view the "lamination" as damascus.

The gunmaker starts with a billet. This is heated, then hammered, ie forge welded.



This animation shows how a blade maker approaches it. They keep welding, drawing out and folding the billet.

Wow you guys what an amazing site, I am no good with computers so you will have to bear with me, I do not know how to add pictures but I have some that you may like on the damascus picture trail, perhaps I can send a disc to someone and they can add them for me. I am from the uk my grandfather blacked and browned gun barrels all his life like his father and grandfather before him they have done this work for over 150 years ( I am still tracing the familly tree!) they are well known for their work here, when my grandfather had the business in london they finished the barrels for all the well known makers Purdeys, Boss, Holland and Holland, Rigby etc, he started in the trade at 12 and his first job was to go around all these famous firms with a hand barrow collecting and delivering all the barrels. if you guys are interested in what happened to this gun finishing familly let me know. Also I have a set of miniature muzzle loaders that my grandfather made everything works on them, he made everything by hand including damascus barrels, there are two flintlocks and two percussion a single and double of each, I would love to put some pictures on here

Posted By: barrel browner Re: Damascus explained - 06/20/07 07:43 PM
The first barrel is a blacking job using a rusting process, the second is the miniature muzzle loaders my grandfather made, he started making them in the late sixties as a hobby,the only work he did not do was the engraving that was done by Ken Hunt, I will sort out some more pics of the barrels, ( if anyone has a pair or piece of scrap Star or bernard barrels I would be interested as I have not seen these before), As I have already said my grandfathers familly were well known for there work, when he trained me he was 73 and I was 15, he passed away without writing down or telling me his secret formulas I have all the old formulas his father and grandfather had written down but he had perfected it and modernised it in the 30s but kept it all in his head! anyway the last picture is a set of three iron damascus barrels that I have done one side only showing before and after I am now forty and I want to be known for my barrel work I am not there yet but I am sure this site is going to be a great help, I would also like to say a big thankyou to the late Oscar Gaddy he was a great help to me when I started doing this work again his advice helped me recreate the old fashioned english finish

Excellent observation Mark (and I think we've seen those guns in another thread?)



Marked 'Laminated Steel' but certainly appears to be a 'large scroll' Crolle, but I can't discern the ribband weld lines clearly to call 2- or 3- Iron.
I'd look for Belgian proofmarks on the brls.

Posted By: Drew Hause Re: Damascus explained - 06/26/07 02:00 AM
Still working on getting damascus patterns identified. This large scroll Two Iron Crolle pattern might be "Boston Damascus"-anyone with a similar pattern?

Posted By: 775 Re: Damascus explained - 06/26/07 03:22 AM
Yup.....on the way. But I call that as a "one iron"........only one core( or "star" ) between the weld lines?

My example should be up tomorrow morning, #2 Flues, 1912ish, marked "LLH".

Methinks the core of the "ribband"...or is it the "skelp" appears as a star, or cross...as it would be the least likely to twist and give a pattern during the whole twisting and forging process.

Hence the dense "core", with less figure.....but the radiating ends that give the "croll"

Some of the other examples offered up would support this, no?

Best,
Mark
Posted By: Robert Chambers Re: Damascus explained - 06/26/07 03:52 AM
In reference to Rev's most recent photo...above

Please, could someone explain how the crosses can go from black to white...so close on the skelp?...

what seems to be the most simple pattern, at first glance, now looks mystifying to me...

Are mixed crosses common, and I've just not noticed it before?

Rev, Thanks for the course in damascus barrels, will there be a written test? I feel like I should have paid tuition...well, sort of...
Posted By: 775 Re: Damascus explained - 06/26/07 04:04 AM
I am with you on that Point Robert!

My guess is the small strips that make up the bar are composed of various length "bits"...and thus vary the "bright" and "dark" stars? That, or they are slightly off center and you get the alternating pattern?

I could be way off on several levels on this....would expect it actually, but thought it would be good food for thought?

Best,
Mark
Posted By: Robert Chambers Re: Damascus explained - 06/26/07 05:10 AM
Bits...thats a good guess...but now it's everywhere...in fact I can't find one that's not mixed...even the one the picture trail "Terrell" is mixed...I have some reviewing and head scratchin' to do...my guess is wire...not only was the technology 'old hat' in Europe, so late in the industrial revolution, but wire can be intracately woven, drawn, twisted, welded, and flattened into a skelp...it can be so intracately woven, that you could write a name like Terrell, but the diameter of the wire billet would be so large, that it may have been drawn through a series of rollers into a long wire, before being flattened into a skelp...it's always been my guess for the other lettered barrels (Prince Albert or the word REMINGTON) ...so now my "wire" guess has broadened to include crolle...there are many other factors as to why wire technology is a strong candidate for reverse engineering at least one type of rolled damascus barrels...
Posted By: Drew Hause Re: Damascus explained - 06/26/07 01:24 PM
Once again, the more the think you know, the less you really do!

Mark: the pattern certainly looks like two 1/2 scrolls between each ribband weld BUT Dr Gaddy's One Iron example seems to show one 'smashed and smudged' full scroll between the weld lines



On the ? Boston pattern, I'm calling the round and symmetric scroll as the center, with two 1/2 scrolls on each side (that don't form another round scroll) =Two Iron.

And re: the 'stars' between the scrolls, you can identify some that are 1/2 black (iron) and 1/2 white (steel)! Since we're looking end-on at the twisted billet of alternating iron and steel, the size of the 'star' depends on how small and tightly wound the rod was. And it seems the higher quality Crolle has smaller scrolls and 'stars' between them. And the color of the star depends on which tiny rod within the billet happened to be on the outside of that twist? Please tell me that makes sense

And I just read in a Double Gun Classics e-zine that Daniel Wesson is reported to have ordered 400 sets of barrels from a Belgian source, 200 of which had "Wesson" spelled out in the damascus pattern. Has anyone seen one?



Posted By: Drew Hause Re: Damascus explained - 06/26/07 03:37 PM
This Two Iron Crolle also appears to have a indistinct weld line down the middle of each scroll, though the ribband weld is more obvious

Posted By: Drew Hause Re: Damascus explained - 06/27/07 08:04 PM
Here are the brls on the c. 1890s Greener at Cabelas which is being discussed on another thread



Much less symmetric and 'more open' scroll pattern but with the same weld line in the middle of each scroll. I believe this is also Two Iron crolle and both white and black 'crosses' can be seen (it helps to 'zoom' the pic.)

Now we have an explanation for 'Laminated Steel', and much more!

http://books.google.com/books?id=-QUtAAA...I6tLQ#PPA160,M1

Journal of The Federation of Insurance Institutes of Great Britain and Ireland, 1904 "Gun and Small-Arms Factories" by A.E. Patrick, p. 149-175
From 'Gun Barrels' starting on p. 159:

The iron for the manufacture of sporting gun barrels was formerly made from finest scrap iron, such as old horse-shoes, nail stubs and the like. In preparing the metal for the old-fashioned laminated steel barrels, a number of scraps were collected of various proportions, the clippings of saws, steel pens, and scraps of best iron, which were placed for some time in a shaking barrel for cleansing, and then hand picked, in order that any pieces which had the appearance of cast iron might be removed. They were then cut into pieces of the same size, melted together, gathered into a bloom, and the mass placed under a tilt hammer, welded into a block of iron which was immediately rolled into bars. The bars were then cut into regular lengths, and the required quantity laid together and fastened into a faggot, this faggot was again heated in the furnace and hammered and rolled into rods of the size required by the barrel welders. The supply of fine old scrap does not now meet the demand, so at the present time the metal for gun barrels is made from a mixture of the best iron ores. The iron is made into rods, and subjected to hammering and rolling, which condenses the metal and increases the ductility and tenacity by elongating and densifying the fibres. The faggots are heated and welded seven times during the process of manufacture of the best barrel metal. The iron for the manufacture of gun barrels is made in square rods of various thicknesses for the best barrels, and in flat rods for plain twist or scelp barrels. To give the Damascus figure the square rods are first twisted, the operation being carefully overlooked to guard against one portion being twisted more rapidly than the other. This process is repeated until the rod is perfectly twisted and a regular figure in the barrel insured. It is this twisting of the rods that makes the difference between a best barrel and a common one. All Damascus barrels must be made of twisted rods. Plain twist or scelp barrels are made from plain straight rods or ribands. It is the twist in the rods that cause the figure to appear in the barrels and all iron so twisted is called "Damascus," from the town Damascus, where a similar process was first practised for the far-famed Damascus sword blades. The prepared rod is either joined to other rods or coiled and welded into a barrel singly. Damascus barrels are made from one, two, or three twisted rods, and occasionally the Continental makers use four to six rods together. The Damascus barrels, as made in England, are usually manufactured from three twisted rods, which is quite sufficient to form a very fine figure in the barrel. Laminated steel barrels are twisted and the rods welded in the same manner as the Damascus, but the rods are composed of superiour metal containing a larger percentage of steel. The rods having been twisted and the required number welded together, they are then rolled at a red heat into ribands. The ribands are then twisted into spiral form, again heated, and the coil well hammered until thoroughly welded. The proportionate amounts of the different descriptions of metal in a barrel determine its quality. Best English Damascus and modern laminated steel contain 60 per cont. of steel. The amount of steel is determined upon before making the metal into faggots for the last time. If for scelp barrels, the strips of iron are twice the thickness of the steel, the faggots being formed of alternate layers of iron and steel. In single iron Damascus barrels the proportion of iron is not much less than the steel, and although not passing through so many processes as the best barrels, is still far superiour in quality to ordinary iron. In twisting the rods every care is taken to keep the edges of the iron and steel strips to the outside, for it is the twisting of the different metals that gives the various figures in the finished barrel. The steel being hard, resists the acids employed in the browning process and retains a white or light brown hue, whilst the iron, or softer metal, is so acted upon by the acid as to be changed into a dark brown or black colour. There is nothing in the process calling for any particular notice as far as fire risk is concerned. If in a suitable building there is no more risk than in a smithy, and in the whole course of my insurance experience I can only remember having one claim for a smithy being destroyed.

Posted By: Drew Hause Re: Damascus explained - 08/05/07 02:39 AM
Jack:
Claude Gaier's Four Centuries of Liege Gunmaking sheds some light on the connection between US and Belgian firms. Ernest Heuse-Lemoine (1834-1926) from Nessonvaux was a major force in the Vesdre Valley for barrel making. He maintained agents in London, Birmingham, and New York and his firm supplied the Belgian royal court. Every 3 years he would travel abroad and upon his return, would be met by a band in celebration because he always came back with more work orders than his own firm could handle. He would then distribute some of the work to smaller barrel makers in the Vesdre. Gaier states that Heuse-Lemoine supplied damascus barrels for at least 50 years to US makers, and that he invented the names of "Boston" and "Washington" damascus especially for the American market.
Posted By: Jerry V Lape Re: Damascus explained - 08/05/07 02:39 AM
Boston didn't come in last, it was included in the top 30 best steels for barrels. There were lots of others of less value. Note that none of the twist types are listed, nor are steel skelp formed barrels steels.
Posted By: Drew Hause Re: Damascus explained - 08/05/07 03:08 AM
From The Gun and Its Development, W.W. Greener, 8th edition, 1907

The word laminated, as the designation of a gun barrel, arose from the fact that…thin strips, plates, or laminae of steel, piled alternately with iron plates, formed the composite metal. They differ from Damascus in so far as the iron and steel are differently arranged in the pile, so that instead of a decided curl in the figure there is only what may be termed “herring-bone” lines running spirally round the barrel from end to end.

Hey Drew,

Nice synopsis. Normally I would have doubts about Pieper as a source. However, Pieper and Remington seemed to have a special relationship. He was licensed to produce several of their guns. He also seemed to have a special relationship with Colt. Some of the Bayard pistols are direct Colt imitations. They may have felt an affinity for his company. He did model it heavily on what he observed during the American Civil War. In particular the reliance on mechanization for manufacturing.

I finally obtained a copy of "Bayard Les hommes, les armes et les machines du Chevalier Pieper & Cie 1859-1957" par Michel Druart. It is ok. Unfortunately he attempted such a broad survey of Pieper's life, career and legacy that many things are just not mentioned.

Pete
Posted By: Drew Hause Re: Damascus explained - 08/09/07 09:19 PM
Well, I've found out some more stuff so did a bit of editing, so here it is:

Named patterns used by Remington
London (Stub Twist), Twist, Laminated, Boston N. (Horse-shoe pattern), Boston 2 S.J. (large scroll 2 Iron Crolle), Oxford 2 & 4 S.J. (smaller scroll 3 Iron Crolle in several different patterns), Chain J, Etoile 3. B.P., Legia P. (Herring-bone pattern), Washington N 3. B.P. ("Stars & Stripes" or "American Flag Bunting"), Chine P ('mottled'), Ohonon 6 S.T. (similar to Bernard I), and Pieper P.
The Remington Damascus salesman's sample rod is shown on p. 275 of Charles Semmer's Remington Double Shotguns.

The significance of 'S.J.' (Boston 2 and Oxford 2 & 4) is uncertain, but could be Simonis-Janssen http://www.littlegun.be/arme%20belge/art...moulin%20gb.htm
'J' could also be one of the Janssen families http://www.littlegun.be/arme%20belge/artisans%20identifies%20i%20j%20k/a%20janssen%20gb.htm
The meaning of 'B.P.' (Washington N and Etoile) is unclear.
Claude Gaier's Four Centuries of Liege Gunmaking states that Ernest Heuse-Lemoine of Nessonvaux named both "Washington" and "Boston" patterns for the US market. http://www.littlegun.be/arme%20belge/artisans%20identifies%20h/a%20heuse%20gb.htm
Boston N. and Boston 2 first appear on the Model 1878. Boston and Washington patterns are also found on Baker and Ithaca guns.

Damascus barrels with possible Belgian maker's marks include 'HP', frequently found on Oxford 4, likely Henri Pieper http://www.littlegun.be/arme%20belge/artisans%20identifies%20p/a%20pieper%20en%20tete%20gb.htm Oxford patterns are used from the Model 1876 to the 1900 KED.
An Etoile pattern 1894 Pigeon has a fused 'JP', possibly the mark of J. Pire & Cie, a large munitions firm established in Liege in 1885 http://www.littlegun.be/arme%20belge/artisans%20identifies%20p/a%20pire%20gb.htm

Remington graded the damascus barrels on Model 1894 guns as follows:
A Grade: "Two stripe Damascus" (Boston)
B Grade: "Three stripe Damascus" (Oxford and Chain J)
C Grade: "Finer Damascus" (Etoile and Washington)
D Grade: "Very fine (Four stripe) Damascus" (Chine and Ohonon)
E Grade: "Finest Damascus" (Peiper and Legia)

The Model 1900 was offered with Remington steel (K) or Two stripe Damascus (KD).

And I wonder if the Beretta 'Thonon' is the same pattern as the Remington 'Ohonon 6 S.T.'
Posted By: PeteM Re: Damascus explained - 09/05/07 03:44 PM
Well, Thonon-les-Bains (Thonon-the-Baths) is a town in France. As best as I can make out, ohonon is a Welsh word. None of online dictionaries will translate it though.

The pattern I would like to see is what Beretta called Japanese.

If you have on the early Beretta guns, 1900-ish or earlier, please do post an image.

The Remington "Chine P" pattern could be either 'China' or 'mottled' (which is what it looks like.) Would love to be able to compare that to the Beretta 'Japanese.' You know there had to once be a 'Salesman's Damascus Sample' like Remington's.
Posted By: PeteM Re: Damascus explained - 09/18/07 04:17 AM
OK, some more suppliers, info.

Found on Lefever damascus barrels, ADH.
ADH was the trade mark of Delvaux-Heuse. This was a joint venture between two powerful companies. Jacques Delvaux and Heuse held a joint patent for the making of damascus, circa 1892.

Thonon
There were at least 20 different Belgian companies that operated under the name Thonon. It was in use from approximately 1836 to 1941. At least one, Fernand Thonon, was the proud distributor of arms to courts of Italy and the court of the Grand Duchy of Luxembourg.

So, I think it might be safe to assume that the Beretta catalog reference to Thonon damascus was produced by Fernand Thonon & Co.

Tuesday Oct 9 at 8pm PBS will air a Nova episode titled "Secrets of the Samurai Sword" in which the trailer hints at using modern technology to unravel the mystery of the steel......there is enough similarities between samurai sword steel and damascus, that surely we will all learn something applicable.

Robert,

Sounds interesting. I am currently working on a lead from my readings. Gaier believes that 1683 is a key date in the development of European damascus development for gun barrels. The defeat of Kara Mustafa Pasha by Jan III Sobieski at Vienna was a winfall for European gunsmiths. Suddenly thousands of damascus barreled guns could be examined.

He intimates that while the crusades had made Europe aware of damascus blades, it was the defeat of the Ottoman army that advanced damascus barrel technology used in shoulder arms for Europe. This technology was refined by Europeans to reach it's zenith in the 19th century.

The Japanese development is important. They only had Akome iron sand instead of the standard iron ore. Yet because of the ama-no-habuki bellows, which unlike western bellows, allow more oxygen, thus a hotter forge. They were able to reduce the impurities and became masters at controlling the hardness of the metal.

There is much theorizing today that wootz steel was dependent on impurities found in the local ore scource.

The fall of Vienna was a waterfall event for European gun makers. Eventually all military technology finds it's way into the private sector.

"Gaier believes that 1683 is a key date in the development of European damascus gun barrels. The defeat of Kara Mustafa Pasha by Jan III Sobieski at Vienna was a winfall for European gunsmiths. Suddenly thousands of damascus barreled guns could be examined."

This COULD be a foundational observation as to 1. how damascus made it to Europe and 2. why 'pattern welded' iron/steel barrels were developed in the first place.
Islam forbids the depiction of Allah or Muhammed, and the creative/artistic efforts of the different Islamic people groups were focused on Calligraphy and Architecture. There are 6 major script patterns, called Shish Qalam in Persian and Turkish.
These sites are helpful:
http://www.islamicart.com/main/calligraphy/index.html
http://www.sfusd.k12.ca.us/schwww/sch618/Calligraphy/Islam_Arabic_Calligraphy.html

This is Farsi script called Ta'liq and popular among Persians, Turks, Arabs, and Moslim Indians. The repetitive pattern of swirls is similar to 'Turkish' crolle.



This is Naskh script which is somewhat like 'Horse-shoe' crolle.



Could damascus have originally been inspired by 'Wootz/Crucible' steel (which is NOT pattern welded) and made in an attempt to reproduce Islamic Calligraphic patterns?!?

Posted By: PeteM Re: Damascus explained - 10/05/07 04:40 AM
I think to look for Arabic in the patterns would not result in a typical barrel or blade. To look at a culture's sense of art and decoration as it was carried from one media to another makes a lot of sense. "We" have been decorating hunting weapons for thousands of years. The British engraving of the 1800's was flowing from the Victorian "culture". It is what appealed to them. In the same way, the blades and barrels of the Ottoman empire were decorated in a manner that flowed from their culture.

I remember Oscar once referenced Leo S. Figiel, "On Damascus Steel". So at the time, I purchased a copy. I read through it and put it away. I recently picked it up again. Figiel spends the majority of the book dealing with blades. Only the last chapter really digs into barrel making. A lot of the examples are styles of mechanical damascus that were never copied in western Europe. ( I do wish I had written down all the sources Oscar mentioned.... )

Put succinctly, neither crucible nor mechanical damascus were a European invention. The technology did not suddenly appear and then just disappear. There is a lot of history and cultural intercourse occurring to produce even simple damascus shotgun barrels.

In understanding how it all came about, the contribution of each culture along the way and how it eventually ended, we learn.

Some people are only interested to know where those damascus barrels on their what ever shotgun came from. That is fine. A subset of all this has been to identify Belgian makers and understand the commerce that occurred. As tariffs were raised in the US, the Belgians responded with product that met the need and the price. The flip of this seems to be that some English firms went out of business because they could not compete with the Belgian labor rates (still working this piece).

A bit of trivia...Liege was under siege in the 1300's. It eventually fell. It is the 1st known use of hand canons during a siege. Liege was important because of it's long tradition as a center for bladed weapons.

I know how often I have dismissed the damascus blade as a dead end when researching damascus barrels. But I think, in a small way, I am beginning to understand why Oscar considered Figiel important. The blade evolved from crucible (or bloom) to mechanical damascus. The damascus blade was a necessary step to the damascus barrel.

Posted By: rabbit Re: Damascus explained - 10/05/07 09:51 PM
I'm buying exactly this much of it. If steel is difficult to make in large quantities you combine it with something more readily available. Quite common for even late 19th C. plane irons to be a laminate of steel and soft iron--the iron for the body, the steel for the edge keeping. Also, there are dozens of traditional constuction techniques that rely on the repetitive iteration of weaving, lacing, cross-battening. Planked boats and stick-built houses, baskets, wattle fences, cane weaving, crochet, macrame, all follow this model. You may be able to spill bore a barrel but it's easier if there's already a piercing from the mandrel it's struck on. Big machine tools indulge the modern urge to hog everything out of the solid. Surface appearance is probably incidental initially but is made into a "trademark" art. Wow, look at what we get when we twist it this way with this many elements. I imagine the barrel makers understood hoop strength and how to attain it. If their product had a distinctive look that tied it to their manufactory, so much the better.

Drew-

Allow me to be among your first customers, I am sold. In fact I would be surprised if there was no connection between damascus and the Indo Persian and/or Islamic Arab cultures.

It would surprise many to learn that Western culture owes a great and long unacknowledged debt to the Indo Persian culture and the later Islamic Arab culture. Without Arab scholars and libraries much of the ancient Greek and Roman knowledge which now forms the basis for many of our laws and much of culture would have been lost forever had we not "re-discovered it".

It would also surprise many to learn that English is an Indo European language or to learn that "Arian" as a regional designation, is in fact "Iran." The similarity in the two words is not co-incidental. Speaking of words; in Farsi the word for father is "padar", mother "madar", brother "baridar", and the word for right "rost" to mention only a few. Familial and common words tend to evolve less over time.

People, ideas and technology moved around back then, only more slowly. As I am sure you will note, one only has to look to the Bible to see how Paul and the early church managed to move around.

While on the subject of common ground, Jews, Christians and Moslems all worship the God of Abraham. That Catholics and Protestants have killed each other for years over real and imagined difference "worth dying over", it really should come as no surprise to anyone that greater differences (those between these three major religions) have proven fuel enough for senseless killing. Passions are high this day and age, but it should not blind the pursuit of truth in any forum.

Joe doesn't mind the Arabic numerals. And I don't mind the concept of predecessors, influences, borrowings. I'm sure it was Money See, Monkey Buy, Monkey Copy on all the trade routes. So long as you don't attribute a strong consciousness of the historic lineage to the rank and file, I don't see a problem. So some Templar Knight liked his booty so much he got somebody to copy it and it stuck as the fashion. I'm not too happy looking for specific carpet patterns which suggest specific barrel patterns. Most people take the ball and run with it. If they slavishly copy, they're usually copying the ball that Dad ran with. Clearly the survival of the name Damascus is a pointer to the geographical origins of ferric composites.

Posted By: Drew Hause Re: Damascus explained - 10/05/07 10:36 PM
Then again maybe Jack is right
Since "God hath made all men of one blood", all people groups likely have a shared creative/artistic nature, which will manifest itself with shared images and patterns within a unique cultural context. The swastika is widely used in Eastern religions: Hinduism, Buddhism, and Jainism, AND by the Navajo Nation.
Sure is fun to think about though!
BTW: as Doug said, western Europe was in the middle of the 'Dark Ages' when the Indo Persians figured out how to make steel. And the Philistines gave iron to the Hebrew people about 1000 BC.

We might owe the Chinese for the earliest Damascus they were forging steel blades in the 4th and 5th century and had the best steels. Japan was the country that took it and refined it. During the Heian period(794-1185) the japanese made great progress improving the imported steelworking techniques. It was in the Kamakura period (11858-3333) that they refined the technique of using high carbon steel folded over low carbon steel to make steel of great strength. The first damascus was designed for strength not beauty. The Japanese steel was folded into a very fine grain,i have never seen any that was twisted. I believe twisting it for designs was most likely a European invention, don't realy know.

W.W. Greener in "Modern Breech-Loaders" states on p. 101 that "Barrels were first grooved or rifled at Vienna, about the year 1498." Coupled with p. 77-78, "Mr. Hallam, referring to the authority of an Arabic author, infers that there is no question that the knowledge of gunpower was introduced into Europe through the meands of Saracens, before the middle of the thirteenth century; and no doubt its use then was more for fireworks than as an artilierist projectile force. There is good evidence, too, that the use of gunpowder was introduced into Spain by the Moors." And what kind of folk were the Moors? Anyway, if they rifiling to prevent fouling and using gunpower as an accelerate in the later part of the 15th century, then what type barrel were they utilizing?

“Something has been said about the chemical excellence of cast iron in ancient India, and about the high industrial development of the Gupta times, when India was looked to, even by Imperial Rome, as the most skilled of the nations in such chemical industries as dyeing, tanning, soap-making, glass and cement... By the sixth century the Hindus were far ahead of Europe in industrial chemistry; they were masters of calcinations, distillation, sublimation, steaming, fixation, the production of light without heat, the mixing of anesthetic and soporific powders, and the preparation of metallic salts, compounds and alloys. The tempering of steel was brought in ancient India to a perfection unknown in Europe till our own times; King Porus is said to have selected, as a specially valuable gift from Alexander*, not gold or silver, but thirty pounds of steel. The Moslems took much of this Hindu chemical science and industry to the Near East and Europe; the secret of manufacturing "Damascus" blades, for example, was taken by the Arabs from the Persians**, and by the Persians from India.”

Great stuff guys.
M. Sache in "Damascus Steel, Myth, History, Technology Applications" states that BOTH pattern-welded Damascus AND wootz Damascus blades were first produced around 500 A.D.
In terms of shotgun barrels, it's going to be very important that we don't mix blade production techniques (folding laminates) with damascus barrel techniques (twisting laminates and welding the ribband edges.)

per http://www.memagazine.org/may07/features/straight/straight.html
the English were first introduced to the 'hand cannon' in 1429 at the siege of Orleans.

I'm going to go ahead and re-post some links for infro on Wootz steel, the first by a damascus expert at Iowa State:

And here is a section of a book discussing cast iron cannon barrel and damascus gun barrel production. It states that damascus gun barrels were being produced in Turkey by the late 1500s

Drew-

Agreed, but don't you think the material iron/steel in question and concepts for working the materials are most likely related? It would stand to reason early barrel makers were drawn from the ranks of those who had access to and were schooled and skilled in working in those particular materials. This may have also formed the basis for the common esthetic you noted in your earlier posts.

While blades may be folded and barrels twisted, lamination is the common technique and one that would appear to have originated hundreds of years before damascus shotgun barrel production.

The German blade smiths have done a lot of study into the history and making of damascus. While we currently seem to be lacking extentive documentation, there had to be German barrel makers producing damascus tubes.

This is a close up of a pattern welded spearhead circa 800 AD


A blade with pattern welding, circa 1700-1800


Another good source for following the middle eastern theme is Robert Elgood, "Firearms of the Islamic World: in the Tared Rajab Museum, Kuwait". The Victoria and Albert Museum in England have held exhibits of oriental, Persian, Indian, Ottoman firearms. Some are exquisite examples of pattern welded damascus. This same museum has a large collection of iron work from around the world.

I remember Oscar mentioning the importance of blacksmiths working with structural and decorative iron. The source was one he uncovered at the university library. I tried to obtain a copy and was stumped. I spoke to him on the phone about it and he just laughed. The "book" was an old doctoral thesis on file there. I guess it helps to be a university professor.

Joseph Manton along with the young Purdey and Boss were so inspired by the beautiful pattern on his Magic carpet that they decided to use it in the pattern of their Damascus shotgun barrels.

Posted By: dbadcraig Re: Damascus explained - 10/06/07 12:56 PM
....likely not too far from the truth, except the magic carpets were sail, then later steam!

The cultural and economic exchange was going on through the East India Company starting in the 1600s. For centuries, England being an island nation of sea faring traders had unrivaled access to world markets.

No doubt commerce, particularly with the older civilizations such as India included the exchanges of ideas and technology not just raw materials.

Even without the possible technological underpinnings, "British Orientalism" and the oriental esthetic may have influenced the barrel patterns. During the time-frame in question (circa 1800s), oriental themes and tastes (e.g., carpets, tea and fine china) were high fashion.

All these traditional processes are laborious and repetitious (following a sequence of instructions hundreds and thousands of times). You don't engage in that kind of discipline and tedium and then hide your love away by deciding that a monochromatic rug would be somehow easier because you could wear your fingers out without producing the universal references. Similarly, you'd have to be a scammer caught in a technological transition to blue over your taffy-pull barrels rather than etching up the patterns which attest to exactly what the barrels are and how constructed. The obvious quibble with the prima facie correspondance of pattern and motif between very different processes is that not all iterative processes are capable of the same subtlety of representation (a twist which will produce a vine on the surface of a gun barrel is not something I've seen). The simpler geometric abstractions (four-rayed star)can be discovered in the possible patterns of twisted steel and iron on the surface of a barrel; the sinuously "organic" as well as the geometric are possibilities in your rugs. I'd say that your rugs have a more extensive vocabulary than your barrels. What both share is a proud statement about the processes of premodern technology.

Geez, you mean you guys can understand that jargon? I still don't think I said concisely what I meant to say, to wit, that it seems to me that "stretching" an expensive but strong and necessary material by adding a less expensive material which just happens to allow a contrasting surface appearance to be "developed" is a matter of economy of means directed at the primary end of utility (read desirable degree of hoop strength). Then the patterns would be incidental to the main achievement. I don't think the rug patterns appear in quite the same context of scarcity and technological limitation.

However, looking back at the calligraphy, I'm beginning to see in the 3-D shading the suggestions of ribbons of ink which could indeed be imagined as the spiraled irons of a damascus barrel. The sorrows of gin.

I do not believe the rugs and the barrels are on a 1-1 level regarding the patterns. It is not like over laying fingerprints. I do think that a culture perceives objects and patterns and dismisses others. I think that it is worth looking at calligraphy, rugs, wrought iron, etc to better understand why a culture found one thing acceptable, another beautiful and yet another trash. I think we also learn about ourselves. Perhaps, when we look at a damascus barrel, we are not seeing it the same way the maker intended. Yet we do find it some how pleasing to eye. Certainly some of the names if not most were descriptive. Yet I fail to see the bunting or flags in the damascus.

There is the story of conquistador ships sailing into a bay. The local people looked at the ships and could not see them. The conquistadors came ashore and the local people saw them. When the Spanish pointed to their sailing ships to explain how they had arrived, suddenly the ships could be seen by every one. Such a thing was just not possible to their minds at first.

Pete (and others)-

Very good points. If we have the ears to hear... .
Damascus barrels are perhaps so very interesting because they stand as a testament of art, craftsmanship and technology. Often the greater the art form the more room there is for interpretation by the viewer. Sometimes in art and literature the interpretation varies greatly from the intention of the artist and often the artist wishes only to be thought provocative. If we were discussing fluid steel barrels or paper clips, most likely the discussion would have been ended long ago. I suspect the craftsmen of these damascus barrels would be flattered to know that both their genre and expressions was the present subject of discussion.

But at what point did it turn from utility to art( at the stage of blades, barrels, etc.)? Or was it ever in the form of utility? We should be far enough removed in time to look beyond the conquerors and their religion to look at the byproduct of the agression as the transfer of technology. Or if it's regarding the events of today, it could be attributed to the cyclic nature of history.

This is a great discussion, relevant to double guns, and certainly a subject of some academic interest. I'm suggesting it started the other way around; an attempt at decorative metallic art was fortuitously found to be of superior utility. Was it function following form??

Well said Doug,
Not that I know anything about identifying American Indian artifacts, but don't ethnic anthropologists identify (say) a fragment of pottery or a rug, as being Navaho (or some other tribe), by the similarities of patterns that appear on their handmade objects? The manufacture of pottery and techniques of rug weaving are even more different than weaving rugs is to weaving damascus.
It likely that Rev's observation is appealing to my notion that at least SOME mass produced damascus was done with WOVEN and rolled wires, rather than stacked bars and straps. I'm convinced that rolled damascus was far cheaper to produce than the hand hammered older brother, and for that reason dominated the market. When somebody claims to have a hand hammered double (I call it a samurai gun) I figure it had better be percussion or earlier. except in rare cases like the Schilling that John Mann posted a photo of recently. One thing for sure, it's not beyond the realm of possibility to think that someone might carry their concept of ornamentation or weaving from one handmade object to a different medium of handmade objects. In fact it's quite plausable...(and without psychedelic drugs)
One question to ask is...does Mohammed's Ladder appear on any rugs of middle eastern origin? Personaly, I don't think the Persian or Indian blade patterns look much like the (woven) damascus crolle barrels that we are comparing them to...but the similarities between the writing and the rugs...makes me think that he's onto something worth examining.

How then can we seperate, or unwind, the utility and art, or from and function, as it is has been wound in history much to the like of unwelding a Damascus barrel or blade to see it's humble beginnings? From a technical background, I would assume(antithesis of exactitude) that art would have been applied to, derived from or composed of technical innovation.

Raimey-

Interesting inquiry and it goes to the heart of the matter. Utility and art are not mutually exclusive concepts and often in nature and in man's pursuits when form most closely follows function , even such things as soup can labels, we find what can be appreciated as art.

I am looking at my display case right now where I have among many interesting things, an old family Testament and an arrowhead. The bible is signed and dated in 1828 in what was common penmanship of the day. The arrowhead I found in our front pasture some 40 years ago when I was walking home from school one day.

Is the work of these individuals, who would hardly have considered themselves artists strictly a question of function or is there some artistry or self-expression at work in this? This is subjective; each, the common written word and the arrowhead served very utilitarian purposes, but in them, at least to my eye there is also art.

Doug

Mohammed's ladder, kirk narduban or the Ladder of the Prophet pattern from a Kurdish dagger, with several "rungs" of the ladder which are alterations in the background pattern running perpendicular to the length of the blade.

And Raimey is likely correct.
Posted By: rabbit Re: Damascus explained - 10/07/07 11:20 PM
Unless I mistake, stocks, receivers and possibly barrels have all been overlaid with carbon fiber composite. The fact that the chosen resin is transparent and the roving pattern visible IDs the material and the construction method. How many would choose such a gun based on aesthetics? OK, some of us would as the appearance attests novelty and being the first on your block etc.

It is interesting that so much of the current aesthetic limits decoration in favor of seamless, smooth all-of-a-piece surfaces--huge extrusions, acres of plate glass, undifferentiated chunks of polymer. Too bad. I've always thought that gunhammers should look like cocks or sea dragons and windoors should have many tiny bottle bottom "lights", preferably about 12 over 12.

Pete brings up the inability to see beyond your experience. Railway coaches initially looked precisely like a coach without the four but with a single "iron horse" out front.

I don't see any problem with blades being laminar and barrels not being merely laminar. If once upon a time in the west someone applied the word Damascus to a "state-of-art" technology, they were certainly paying tribute to its co-opted antecedents in furrin parts.

In your case, calligraphy was a style which was used by the esquire types, learned individuals, in the propagation of history(who belonged to who, what belonged to who and how much is who indebted to whom). In being a student of history required by my profession, I have read countless pages of documents in calligraphy and from first staring at one page for a day(much like the Spanish ships referred to in an earlier post) I am able to read it without incident. But it takes time and effort. In a short amount time in the line of history, we are at 1st paralized upon seeing the form. The Lost Lake point, or whichever it is, was a tool for survival. I have a good friend who is a napper and can make a duplicate of any point shown to him. But 1st the arrowhead was a tool. Now it is displayed as art which really depicts the lifestyle and times of the original user. And I'm not considering the jewelry and the like the Indians valued or traded.

You lost me at widoors...are you referring to windows that are made up of spun glass centers (that kinda resemble the bottoms of coke bottles)? Those aren't bottle bottoms, those are the thick, less tranparent centers of large panes of window glass left over from tin-float glass production.

Here is the problem...we don't have that mind set anymore...years back men knew basically that carbon could be folded into the composite steel...even though the metalurical molecular absorbtion wasn't understood...it stands to reason that one fold won't do it and the more the folds, the more uniformly or thoroughly the carbon was folded in, resulting in a stronger material. The more the folds, the stronger the steel. This type of mind set travelled well...even to the cowpoke out west, buyin' a furrin gun...I believe that it was this mind set that drove barrel industry to produce finer and finer damascus.

We have such along way to go in our understanding of damascus...how are we ever going to deal with the "false gates" that were used to protect the trade secrets...
Posted By: rabbit Re: Damascus explained - 10/08/07 12:11 AM
Good point, Robt. about the cheap panes in the center. I forgot or never knew. Yesterday's cheap is today's artistic. Does however make my point that the prisoners of antique fashion can not always easily distinguish conscious artistry from the residue of process. The conjecture of a wire rather than rod and strap bundle is interesting also. Would that explain the capability to "bring up" names on damascus ribs?

Ross-

I think it is very interesting! What is also interesting is that the fore end covers this spot, so the craftsmen may have actually skillfully placed these "flaw" where they would not be seen. My barrels were likely mass-produced in Belgium, at least as mass produced as damascus could have been. Yet still show evidence of human workmanship. I actually think such "imperfections" adds to the character (and hope they are only cosmetic for the sake of my fingers as I use this shotgun quite a bit). WW Greener reported that 18 pounds of prepared gun iron were required to weld an ordinary pair of 12 gauge barrels. Of course that represented the finest English damascus barrels. I would expect that the Belgian barrels on my shotgun were manufactured with the bottom line in mind. While cosmetics were likely of secondary concern (unless the placement of the imperfection was simply by chance), perhaps cosmetics were of sufficient concern that the craftsmen placed the imperfection in a location where it would not be seen.

Also, on my barrels in this spot you can see what appears to be the wire stub ends as the dots.

Doug
Posted By: PeteM Re: Damascus explained - 10/08/07 04:32 AM
Mostly from English sources... there were at least 300 heating done per tube. A set of barrels would take 3 men two working days to complete. In conversations I have had, I have "heard" a lot of speculation about auto-hammers, etc, but no one has been able to document their use by the damascus makers...

I am guessing... the small "flaw" could simply be an unevenness in the original pieces that made up the billet. A bit of iron over laps the steel where it shouldn't.

There is so much more work to do. We really have not documented, speculate yes, why it all stopped. Was it the rising labor rates, the lack of raw materials, a shift in the economy, buyers simply stopped buying damascus, people simply stopped buying doubles, take your pick....

How important was the American market? Did the tariff wars in congress have an impact on the trade? If they did and the Belgians were the winners, who lost? Was there a Spanish or Italian center for damascus barrels? Who were those makers? We see German guns with damascus tubes. Where the Germans buying the tubes or making their own damascus.

Many other questions....

Posted By: ellenbr Re: Damascus explained - 10/08/07 01:29 PM
Here is a selection from W.W. Greener's Modern Breech-Loaders in detailing barrel making techniques as described by W.W. Greener or his father W. Greener. I don't want to state the obvious or be redundant. So if anyone wants to see the 2 pages this text is contained within, let me know & I'll try to take a pic of it.

"The generality of barrel-makers spoil this metal by an attempt to obtain figure; for all extreme twistings in the rod depreciate the metal by separating the fibres: to borrow a simile, they obtain only an over-twisted rope. This is not only disadvantageous, but useless; for the extreme density of the metal renders the figure difficult to be shown distinctly, as acid acts upon it but slightly, and never so well as on metal fabricated from two differently constructed carbonised materials."

I usually see worksmanship like that on cheapo Belgian or Spanish guns. That thing looks pretty crude to me. I would not shoot it either.
Let me present a quote from very well respected expert (seen references about his work on the other side of the Atlantic):
"Many US shooters are playing self-styled proof-house experts by deciding that their foreign-mde guns can withstand 'X' level of chamber pressure."
Many seem to put faith in Euro C.I.P. 65mm shells some of which can generate above 60MPa of gas pressure.


Posted By: reb87 Re: Damascus explained - 10/08/07 05:45 PM

Im not sure what you mean by crude. Someone dinged the barrel lug with a hammer or something but the Baker guns especially the early ones like mine are very well made and machined to a high standard.








Posted By: dbadcraig Re: Damascus explained - 10/08/07 06:58 PM
reb87-

I would be proud to own that shotgun! It looks very nice to me. I am certainly no expert, but the "imperfection" or disruption of the damascus pattern on your shotgun doesn't appear to be a repair but rather a part of the manufacturing process. Like the imperfection on my Meriden, it appears to have been situated for the sake of cosmetics. If so the manufacture and assembly of these barrels was not haphazard. That may be all this is, a cosmetic. It would appear, given the location in the breach area that the craftsmen of the day considered it no serious safety defect.

I'll leave to Drew or others far more informed to discuss the use of Belgian made barrels on fine shotguns, but I suspect the list is long and includes some shotguns within the higher ranks (even some English make). No doubt the English have a well-deserved reputation for making the best barrels. I have read, however, that even some of the English makes imported damascus from Belgium.

If price is a reflection of where the Baker shotgun was placed in the pecking order, your Baker was no slouch. It was priced at $22.50 in the 1908 Sears catalog (when an LC Smith with fluid steel barrels cost $25 an Ithaca with damascus stub twist cost $24 and my Meriden hammer gun with damascus cost $13.59).

Posted By: Drew Hause Re: Damascus explained - 10/08/07 07:24 PM
This Very Fine Four Iron Crolle is on a Baker Presentation Grade. A quite similar pattern is found on Colt 1883s, Remington 1894 D grades, and Parker DH. We know Baker obtained damascus barrels from Charles Spirlet & Arthur-Delvaux-Heuse and Colt from Plunger-Riga & Heuse-Riga Fils. Remington used several makers, mostly H. Pieper and Ernest Heuse-Lemoine of Nessonvaux. We're still working on Parker's source.

The response I received from Dennis Dodds at the International Conference On Oriental Carpets http://www.icoc-orientalrugs.org/about.shtml
"Damascus steel patterns share and extend the tradition of Islamic ornamenation. Its adaptation to designs on western weaponry is plausible, due to the popularity of adopting Eastern design elements by the West, especially during the 16-18c." He suggested a 1949 book that might have more information. The search continues!

Claude Gaier's "Four Centuries of Liege Gunmaking" sheds some light on the connection between US and Belgian firms. Ernest Heuse-Lemoine (1834-1926) from Nessonvaux was a major force in the Vesdre Valley for barrel making. He maintained agents in London, Birmingham, and New York and his firm supplied the Belgian royal court. Every 3 years he would travel aboard and upon his return, would be met by a band in celebration because he always came back with more work orders than his own firm could handle. He would then distribute some of the work to smaller barrel makers in the Vesdre.

Under one name or another, Pieper or their companies made firearms for nearly a century. The genius of Henri was his early adoption of the American factory system for arms production. Nicolas expanded the business. He is noteworthy for 2 reasons, his early hiring of women in the factory, side by side with men (some thing that did not take place in America until WWII). Also his large scale production of hand guns, which was the Pieper-Bayard mainstay for decades.

Henri Pieper was descendant from his German father, Heinrich Pieper. In the nearly century they were in business they produced rifles, shotguns, cartridges, machine guns, pistols, revolvers, and many military arms. It is easy to say, "They made junk" because at times they did. It also easy to say, "Their guns won just about every award and exposition in Europe", because at times they did. There is a misconception that they flooded the American market with cheap guns. They certainly sold their share of firearms under various trade names in the American market. However, they were not alone. It is simply too easy to assign all JABC to Pieper. Upon closer examination of these firearms, we often find other maker's trademarks and stamps.

Henri was followed in the business by Nicolas. I am not going to get into an exact history, nor listing of guns. It is simply too long.

Some names, trade names, etc associated with various Piepers;
Demi-Bloc, Centaure, Diane, Adler, Bayard, Eagle Gun Works, E.Leroy, P Couronné, The Leader, Royal Gun Works, Premier Arms, Compound Damascus, National Arms, Le Rationnel, Heny Arms

Nicholas Pieper, was in business 1906-1927, 1928-1932 making pistols and other arms with Jean Warnant and Hippolyte Thonon.

In The Gun, or a Treatise on the Various Descriptions of Small Fire-Arms, Greener described 9 different gun barrels at that time, and in general was extremely critical of the quality of British gun barrels being produced:
1. Damascus from only two sources: Mr Clive of Birmingham and George Adams of Wednesbury
2. Wire-Twist Iron
3. Stub-Twist Iron or Stub Damascus. Made from horse-nail stubs (iron) mixed with coach spring steel, fused into a "bloom of iron", then hammer forged into rods, rolled into threads, which were then wrapped around a mandrel and welded.
4. Mr Wiswoulds Iron Barrels and a similar product called Silver Steel. These are described as ¾ steel and ¼ iron and from the description may be Two Rod Laminated Steel
5. Charcoal Iron (without steel) – inferior to Stub-Twist
6. Threepenny Skelp Iron
7. Twopenny/Wednesbury Skelp
8. Sham Damn Skelp which apparently was stained to look like Wire-Twist
9. Swaff Iron Forging made up from small scrapes of lockplates and gunscrews

Posted By: ellenbr Re: Damascus explained - 10/14/07 11:13 PM
In my opinion and from what I have read, an addition that the Wire twist was from horseshoe "stub" nails and other quality irons(saws, pen making waste, etc.) may be required. One of the others, maybe Charcoal Iron, was composed of old coach springs which was considered inferior metal. This was described in "Gunnery in 1858" I believe.

Charcoal Iron refers to the smelting process.

Large tracts of forest were destroyed to provide charcoal to smelt the ore into iron. As time went on other sources of fuel were sought out. The logical replacement was coal. However, the final solution was a coal derivative, coke. So, most smelters turned to coke. The Belgian damascus makers complained bitterly about coke smelted iron. They prized the charcoal produced iron above all other.

It turns out that coke introduces silicon impurities and a certain amount of sulfur, which makes damascus production difficult.

Pete
Posted By: Drew Hause Re: Damascus explained - 10/15/07 02:43 PM
Greener measured the strength of the barrels (strongest to weakest) as:
Wire-Tist
Stub Twist
Charcoal
3d. Skelp
Damascus
Wiswould’s
Clearly at some point, damascus and laminated steel production was refined and improved to the point that British Laminated Steel was the winner of the Birmingham Proof House Test of 1891.


And for all you home chemists-here you go (I don't believe OSHA would approve of this stuff )

On the Staining of Barrels
There exists innumberable recipes, and in fact almost every maker has his own method. The first I have found to answer uncommonly well, and which it would be a difficult matter to excel. It consists of the following ingredients:-
1 oz. Muriate Tincture of Steel
1 oz. Sp. Wine
½ oz. Muriate of Mercury
¼ oz. Stong Nitric Acid
1/8 oz. Blue Stone
1 quart Water
These are well mixed, and allowed to stand a month to amalgamate. After the oil or grease has been removed from the barrels by lime, the mixture is laid with a sponge, every two hours, and scratched off with a steel-wire bruch every morning, until the barrels are dark enough; and then the acid is destroyed by pouring on the barrels boiling water, and continuing to rub them until nearly cool.
Posted By: PeteM Re: Damascus explained - 10/15/07 03:24 PM
Drew is posting a historical note. Not to be attempted today.

Muriate of Mercury, just the thing NOT to have around the house. Mercury was used by the hat makers of 19th century. After enough exposure the term "Mad as a Hatter" was a real observation. It was also used in the original Dageurrotype process. Mercury fumes were used to develop the exposed silver plate. Again with the same result on the end user.

More very interesting Greener stuff. The latest Julia's auction included a Greener SxS Item # 3274 with the top rib stamped "Inventor of Laminated Steel" !? Unfortunately, date of manufacture was not included. I've found no patents for barrel steel for Greener BUT this from The Science of Gunnery, as Applied to the Use and Construction of Fire-Arms by W.W. Greener, 1841 may be Greener’s description of his claim for inventing Laminated Steel:
“I have had as high as three-fourths of steel to one of iron, and where proper attention is paid to clipping of the steel to pieces, corresponding with the (horse-nail) stubs, and properly mixing the whole, welding (in an air furnace) and forging by the heavy hammer, reducing by a tilt ditto, and rolling down to the…rod, a most excellent, tenacious, and dense body of iron is obtained; while, by cutting into lengths of 6 inches, bundling a number together, and re-welding them into a bar, you gain an increased density and tenacity…rendering it…considerably more powerfully strong than any explosive fluid ever yet compounded could burst…”

I also found The Mechanics Magazine, Museum, Register, Journal and GazetteJuly, 1849 Ed. J.C. Robertson
"Paper read on the Manufacture of the Finer Irons and Steel, as Applied to Gun-Barrels..."
Greener described a new method of barrel production using scrap steel from old coach springs.

And more great reading available on-line
The Science of Gunnery, as Applied to the Use and Construction of Fire-Arms 1841 Oxford
http://books.google.com/books?id=ThYkeKlemD8C&dq=w+greener+barrel+patents

“The Syrians were formerly celebrated for their skills in working of iron. Damascus barrels were not to be obtained, at certain periods, at a price less than their weight in silver. The elaborate mixtures of their barrels, swords, &c., entitle them truly to the honour of being the best iron workers…”

“Mr Hallam refers to the authority of an Arabic author…that there is no question that the knowledge of gunpowder was introduced into Europe through the means of Saracens (used to refer to Arabs living in Northern Sinai and a generic term for Moslems) before the middle of the 13th century…”
Greener dates the first use of cannon by the English to the battle of Werewater in 1327 and the invention of portable fire-arms by Italians in 1430.

A reference to the Epistle of the Secret Arts of Friar Bacon is found on p.18

“Our manufacture of inferior gunnery has certainly reached a depth of infamy which never any manufacture in the world reached…”

“Mr Whitehouse, of Wednesbury…has succeeded in obtaining a figure, or as late writers have termed it, “Watering or Jowher”, attests the attention and assiduity he must have devoted to the subject, for the variety is great and handsome…
A many conjectures have been advanced, and an endless discussion created, to account for the Watering or Jowher in oriental sword blades, and genuine Damascus barrels. Anything approaching the truth is seldom met with…”
“The most endless variety possible may be attained; a figure with the carbonized material, showing only the ends or edges of various lamina, or portions of the face of that lamina, may with equal facility be obtained…
It would be a never-ending task…to endeavour to describe a tithe of the varieties that might be made, and have been. The French and Belgians are very expert at this sort of ornamental work.
I have clearly shown, that whatever other qualities Damascus possesses, strength is not one of its properties.”

Gloria a Dios found this C.G. Bonehill (unfortunately without date of manufacture) on an old Greg Martin auction site. The pattern very much looks like that illustrated in Greener's book for the early 1800s English Mr Wiswoulds Iron Barrels-linear rather than scroll. This may represent the earliest attempt at Laminated steel (which looks like herring-bone.) Anyone with a similar pattern?? date of manufacture of your gun?

Posted By: PeteM Re: Damascus explained - 10/17/07 02:27 AM
Figel, "On Damascus Steel"
Figel has a picture of a matchlock rifle from India, circa 1700. He identifies the pattern as herringbone. It bears a close resemblance to the Bonehill barrels. However, the method of fabricating the barrels was very different. I believe this matchlock is held by the Victoria and Albert Museum. So is it possible it was on display when that Bonehill was made?

Henry Blochmann, Henry Sullivan Jarrett, "The Ain i Akbari By Abū al-Fazul ibn Mubārak", Published 1873
Detailing the rule of Akbar about 1590 A.D. in India. Akbar took great interest in the fabrication of firearms.

From Volume 1 of 5.
Quote:
ON MATCHLOCKS
These are in particular favour with His Majesty, who stands unrivalled in their manufacture, and as a markman. Matchlocks are now made so strong, that they do not burst, though let off when filled to the top. Formerly they could not fill them to more than a quarter. Besides, they made them with the hammer and the anvil by flattening pieces of iron, and joining the flattened edges of both sides. Some left them, from foresight, on one edge open but numerous accidents were the result, especially in the former kind, His Majesty has invented an excellent method of construction. They flatten iron, and twist it round obliquely in form of a roll, so that the folds get longer at every twist then they join the folds, not edge to edge, but so as to allow them to lie one over the other, and heat them gradually in the fire. They also take cylindrical pieces of iron, and pierce them when hot with an iron pin. Three or four of such pieces make one gun or, in the case of smaller ones, two. Guns are often made of a length of two yards those of a smaller kind are one and a quarter yards long, and go by the name of bamdnak. The gunstocks are differently made. From the practical knowledge of His Majesty, guns are now made in such a manner that they can be fired off, without a match, by a slight movement of the cock.

These cylindrical pieces can be used to form yet another pattern that has no equivalent in Europe. It is known as the "Circle and Rose", which Figel has pictures of as well as diagrams of fabrication techniques that may have been used.

The Bonehill is most likely of the 1880 -1895 time frame. There is a good chance it came directly to USA in the relatively large orders of 1880-1890, before implementation of the McKinley tarriff of 35% plus $6. I have seen similar guns, but not that barrel pattern.
Posted By: Drew Hause Re: Damascus explained - 10/17/07 06:55 PM
Thanks! It was very much my hope that it was earlier and could identify the time frame for Mr Wiswoulds Iron Barrels. It doesn't look like any Laminated Steel I've seen. Oh well-the search continues
Posted By: Rocketman Re: Damascus explained - 10/17/07 07:26 PM
rdd - keep in mind that those barrels could have been laying around in someone's shop for a long time before being used in this gun. Anybody's guess when, where, or from whom Bonehill got them. The USA guns were on the cheap/machine made side for Brit guns. So, these could easily have been some bargain basement barrels. I'd not be surprised if they were of Belgian origin, either. To get any kind of fix on them, we need to seem more similar with something identifiable as to source and/or age.

Rev,

Getting back to your Greener recipe and method, does that read correct? Just keep applying coats of rusting formula for a whole day and card just once a day?

The boil would give a black, not brown, correct? Thought the English guns were mostly "Browned"?

I have the day off, it's hot and humid with a good breeze. Busted out the LMF that has been sitting around unopened for nearly a year and am giving a "Brown" finish a try.

No worries on the mercury Rev, am trying the "process" with Laurel Mountain Forge solution.

Yup, read that link a while back(and saved it, thank you), seems to be a "black" process though and thought the Greener method still possible with modern chemistry for a "Brown"?

Eureka-now THIS is interesting!!
?SILVER-STEEL FOUND?

In The Gun, or a Treatise on the Various Descriptions of Small Fire-Arms by William Greener 1835, Mr Wiswould’s Iron Barrels and a similar product called Silver Steel are described as ¾ steel and ¼ iron which were also fused into a “bloom”, welded under tilt hammers, then rolled into rods. This might represent early Two Rod Laminated Steel as the 'billet' did not start with the 'piling' of alternating iron and steel strips, but the fused iron and steel mixture which was then flattened into strips, twisted, wound around the mandrel, and welded.
In William Wellington Greener's The Gun and Its Development, 1907, Junior stated that Silver Steel was "used by the author."
A percussion W. Greener 12b #19707 is on the Julia auction site which is stamped "Inventor of Laminated Steel" on top rib. Unfortunately, no close up of the barrels is provided, nor the date of manufacture.
This Keith Kearcher refinished late 1880s Greener G60 was felt to have Bernard I damascus BUT it seems more likely that this is Silver Steel, and does resemble the illustration in the 1935 book



I believe someone here sent me that pic. Anyone else out there with a Greener with similar barrels??

"Laminated steel barrels differ but slightly from those known as 'Damascus.' The former were first made by Mr. W. Greener (senior), of Birmingham, about 1850, and were composed of three parts steel and one part iron. At the present time the best English damascus, as well as laminated steel barrels, contain over 60% of the harder metal, and there is little perceptible difference between Damascus and a laminated Damascus barrel, as both are of very similar workmanship and materials."

Drew-

The gun barrels pictured belong to my younger brother's Greener and I have actually held and fired that shotgun before Keith worked on it. This is really a very sweet shotgun by the way, Keith not only did the barrels but he bedded the stock and tightened up the action, which wasn't too bad as found. The gun has a lot of very well done engraving and really all it lacks is ejectors to make it "all tricked out" and I strongly suspect that as anyone ordering that shotgun could have afforded anything he wanted...the owner simply had no use for ejectors.

When I began to understand, thanks mostly to you, that the white of a damascus barrel represented steel, I too was amazed at these barrels because they had more white pattern than dark (almost the reverse of the typical pattern).

Are "silver steel" barrels rare?

The definition of "steel" is what I took note of in reading some of Greener's publications. If I understand it correctly, they deemed iron(horsenail stubs, saws, etc.) to be better than steel. And then the types of barrels, all with some addition of steel. But as I have said, I think their school of thought changed with time.

Good barrel, receiver, and wood photographs are difficult to take. The closer you can get, the better. The best backgrounds are solid (not patterned) light grey or light blue. It's hard not to get a flash reflection when the photograph is taken inside, so photos are best when taken with filtered sun (just slightly overcast) outside. OR use a sheet of Kleenex over the flash. Orient the barrels left to right (horizontal) rather than on diagonal (hard to crop) and NOT looking from breech end toward muzzle. And be sure and use the 'close up' function on your digital camera. Please try again

Although Wootz/Balat/Crucible steel is not pattern welded, it may have been the inspiration for damascus steel, and found some neat reading here including the report of Maj. General Pavel Anossoff on "Bulat"

From http://met.iisc.ernet.in/~rangu/text.pdf

"Wootz...was coined when European travellers from the 17th century onward came across the making of steel by crucible processes in Southern India in the present day states of Tamil Nadu, Andhra Pradesh, and Karnataka. Wootz was the Anglicization of 'ukku', the Kannada word for steel."

“Wootz was the first high-quality steel
made anywhere in the world. According
to reports of travelers to the East,
the Damascus swords were made
by forging small cakes of steel that
were manufactured in Southern India.
This steel was called wootz steel.
It was more than a thousand years before
steel as good was made in the West.”

Need some help gentlemen. Raimey and I have been discussing Dig's great new book, and it was my hope that he would attach names to some of the English damascus patterns.
This pattern seems to be typical for high grade English guns-a small scroll Three Iron Crolle but with what looks like a weld line down the middle of each row of scrolls (making identifying the true ribband weld line quite difficult)





Was there a 'name' associated with this pattern? Thanks!

There is a very similar pattern in black & white in Charles Semmer's "Remington Double Shotguns" on page 272 defined as: "Style: Oxford 2 S.J. - Model 1882, Grade 4." If you have the text, have a look and let me know as I am on the hunt. Also, on page 271, "Style: Twist - Model 1889, Grade 2" has the repeating bands in a London style. I would venture to guess that the twist pattern is an even number of "steel" and iron. And your pattern is an odd multiple of "steel" and iron. What do you know about the Belgian pattern 3 Iron Crolle(number of braids & the like)?

In Dig's book on page 85, a "G Grade" looks to have the same repeating pattern but there is a lot of glare in the pic. Any "G Grade" Greener pics in your bag of tricks?

Last, in Greener's "The Gun" 9th edition on p. 235, "The true English Damascus barrel is prepared from three rods, twisted as described and put together as shown in the twisted riband, and is know technically as three-iron Damascus: the silver-steel Damascus is similarly made, but of different metal piled in a different order." So I now would guess that could be some variant of "Silver-Steel Damascus." Thoughts, waaaaay off base?

I'm re-posting the Keith Kearcher refinished late 1880s Greener G60 which might be 'Silver Steel' (courtesy of Doug Craig)



The difference between Damascus and Laminated is:
1. Higher steel content
2. Better quality steel
3. Fewer twists of the rods
4. The steel and iron is mixed together in a "bloom" which is then welded, pounded, and rolled into rods. The rods are then twisted and wrapped around a mandrel like damascus. Damascus, however, starts with separate thin strips of iron and steel which are twisted and welded together.

The usual laminated pattern is, therefore, an irregular mosaic of iron (black) and steel (silver)



BUT might have a distinctly 'herring-bone' linear pattern

OK all you right-brain challenged philistines. I believe it was rabbit who volunteered to have a gin or five and provide an official determination as to the connection between Arabesque and Damascus steel.

From Ernst Kuhnel The Arabesque; Meaning and Transformation of an Ornament, 1949. Translation by Richard Ettinghausen, 1977

"Although it was the Arabs who invented the motif and fixed its image, Muslim artists of all tongues, Iranians, Turks, Indians and Berbers used the arabesque and provided new variants. At times, Western draughtsmen were also unable to escape the charm of these strange patterns, which for a while even turned into a European fashion.
As in the case of other scrollwork, the arabesque, too, consists essentially of stem and leaf. However, while the botanical identity of the grapevine or acanthus is more or less reserved in whatever application it might be found, there is no such organic connection in the case of the unnatural, bifurcated form of the arabesque. It can present itself as being squat or stilted, compact or loosely composed, smooth or with a rough surface, ribbed, feathered, or pierced, painted, round or convoluted, simply outlined or with a spirited contour…serial arrangement with mirror images or upside-down repetitions, the creation of calyx or palmette forms by means of reciprocal duplication, the articulation through geometric strapwork or through cartouches and medallions.
One of the main applications of the arabesque was its combination with epigraphy. In the whole Islamic world, the preferred decoration of buildings and objects was the written, pious phrase and the surprising wealth of resulting calligraphic is well known…inscriptions were usually bedded on a ground of bifurcating scrolls…"

Doc-

Not everyone will see, or will admit to seeing, what you see (I do by the way). You could be totally wrong. In the study of history and the study of other human events, one learns that just as it is difficult to know cause and effect the instant a thing happen, it can be equally, if not more difficult to know this upon reflection. E.g., we struggle to understand the recent history of powered flight (who did or who copied what.)

But the evidence is piling up in favor of the connections you are making between non-European (much less non-English) influences in the patterns/motifs, and perhaps even in the technology and there has been very little evidence to suggest otherwise.


Doug
Posted By: ellenbr Re: Damascus explained - 10/23/07 02:26 AM
revdocdrew:

I don't know if I totally agree with the difference. I don't think that the iron & steel is mixed before being fused and experiencing the 3 ton forge hammer for the Laminated. It is the steel only, from mild steel parts, that is fused. I believe the alternating rods or steel and iron are later. The steel is made from the bloom.

The main difference in Laminated & Damascus is the quality of steel, as you stated & the number of flat bars from the twisted rope lathe. Before the Laminated barrel can be made "The gun-iron makers not get a long strip of mild steel the thickness required, and then a bar of superior iron the same size;.." Also, Laminated is made from 2 rods "with the inclinations of the twist running in opposite directions." And Damascus is composed of 3 rods.

It seems that the definition of Laminated & Damacus change as time marches on; therefore, the definition of Laminated & Damascus will be time varying. I believe that iron starts out as a major percentage and steel lands up being higher later on. Also the rods or iron & steel are different sizes & shapes. In Greener's 9th edition, he mentions old and new laminated.

All above from Greener's books.

Posted By: Drew Hause Re: Damascus explained - 10/23/07 04:27 AM
Raimey-you may be correct, and both Greeners confuse me by mixing the names of the different barrel material. In The Gun, or a Treatise on the Various Descriptions of Small Fire-Arms 1st Edition 1835 W. Greener discusses the manufacture of
Stub-Twist Iron on p. 24
(Steel and iron)...after being properly mixed together, they are put into an air furnace and heated to a state of fusion, in which state they are stirred up by a bar of the same mixture of iron and steel, until by their adhesion they form a ball of apparently melting metal. During this process the bar has become sufficiently heated to attach itself to the burning mass, technically called a bloom of iron...By this mode of manufacturing, the iron and steel are so intimately united and blended...
He also described the bloom in reference to Mr Wiswould’s Iron Barrels and Silver Steel.
In The Science of Gunnery, as Applied to the Use and Construction of Fire-Arms, 1841, He discusses the "bloom" again on p. 98 & 109.
On p. 154 of Gunnery in 1858: Being a Treatise on Rifles, Cannon, and Sporting Arms, he discusses Silver Steel and common Twist Steel (though at other places uses the term 'Silver Damascus'), states "I make my own laminated steel" (is it Silver steel?) then discusses the bloom mentioning ONLY steel and no iron?!
On p. 167, he seems to be promoting some (his?) superior barrel material. "The mixture of a portion of steel with the stubs having clearly shown an improvement...we have had as high as 3/4 of steel to 1 of iron. Where proper attention is paid to the clipping of the steel to pieces, corresponding with the stubs, and properly mixing the whole, welding and forging by the heavy hammer, reducing by a tilt and rolling down to the smallest description of rod, a most excellent, tenacious, and dense body of iron is thus obtained."
I remain confused

Now Joe, I'm just trying to make this here hemp into rope--not smoke it so don't get your knickers in a twist. I don't know that Doc's view of things even differs much from the R&D approach of Tom Edison or Uncle Dupee's flubber mixers.

Confused I am and the more I read the more confusion there seems to be on the surface. So, as you have stated depending on which Greener & which book the terms "damascus", "iron", "laminated" & "steel" seem to have varying definitions. It is probably due to changes in barrel technology and their desire to sell barrels and guns. W. or W.W. Greener both would have made fine politician, speech stumpers and the like, if they weren't already.
If you get a chance look the definition of laminated in "Modern Breech-Loaders: Sporting & Military and add it to the mix. Is there anyone around that knows how the rods were to be combined to achieve a desired pattern? Or are there recipes stashed somewere in archives.

Came up with this:
"Damascus or twist-steel barrels are made by layering alternate strips of steel and iron then welding them together. The strips are then twisted until they resembled a screw, three of these wound strips are then welded together, wound around a steel mandrel, then welded and hammered into a barrel tube. Laminated steel barrels are a bit different. They start with a ball of steel and iron that is then hammered into long strips and twisted, then, like their Damascus cousin, wound around a mandrel, welded and hammered into a barrel tube."
From The Shotgun Encyclopedia by John Taylor

It would be a fascinating trip to explore the Belgian Patent office (if I spoke French.) It's likely most of the Belgian damascus patterns were patented, and likely the patents were ignored as all the members of Syndicat des Fabricants de Canons de Fusil de la Vesdre made 'Bernard', 'Boston', etc.
Desire Mineur, of Prayon, Liege, claimed exclusive rights to "Chain-pattern" damascus in 1904, despite the fact that the pattern had been used for at least 20 yrs.
Posted By: ellenbr Re: Damascus explained - 10/23/07 01:24 PM
revdocdrew:

Also, examining the core definition of laminated requires the use of strips. Either Greener was about the only authority on damascus barrel making or he lifted the plates or figures from someone who did because almost all the sketches I have seen either reference of look curiously familiar to Greener's. What year was Tayor's book or what was his reference. Being redundant, I still subscribe to the thought that the mixture in making Damascus changed with time(amount iron > steel, then amount steel > iron). But what was the definition of iron in the beginning?

But you have to be correct in your statement because in Dig's book laminated steel is defined as being "made from best quality steel scrap mixed with some charcoal iron and worked under a forge hammer repeatedly until the close and even grain desired was achieved." I just need to rationalize it for myself because if you read some of Greener's ramblings in "Modern Breech-Loaders", it is not so apparent unless you know the composition of the "mild steel" and others that are mixed.

Unfortunately then, as now, words mean simply what the writer intends for them to mean, and once an opionion or statement is made, it is repeated thereafter over and over until it is established as 'common knowledge.' Dig's statement about laminated steel being made with charcoal iron is a new one. It is very likely that production techniques changed significantly through the 1800s. Certainly Greener thought damascus was weaker than Stub Twist in 1835. Some form of Laminated steel seemed to be the barrel of choice for high grade guns in the 1860s-1870s, then English Three Iron Crolle (at least by Purdey), then Whitworth steel by the 1890s.

Lascelles, Simon Fraser Lovat 1886

A Short History of Gun-making starts on p. 83
http://books.google.com/books?id=MT9NF4B...and%22#PPA51,M1
Best Silver Steel Damascus barrels contain over 70% of the finest steel, and it is the systematic twisting and arrangement of the iron and steel bars, as they are welded together and beaten into a flat ribbon before being coiled into the form of a tube, that give the beautiful figure or pattern observed in a first-class twist barrel...
Laminated steel barrels differ but slightly from those known as 'Damascus.' The former were first made by Mr. W. Greener (senior), of Birmingham, about 1850, and were composed of three parts steel and one part iron. At the present time the best English damascus, as well as laminated steel barrels, contain over 60% of the harder metal, and there is little perceptible difference between Damascus and a laminated Damascus barrel, as both are of very similar workmanship and materials.

From the Journal of The Federation of Insurance Institutes of Great Britain and Ireland, 1904 "Gun and Small-Arms Factories" by A.E. Patrick, p. 149-175 From 'Gun Barrels' starting on p. 159
The iron for the manufacture of sporting gun barrels was formerly made from finest scrap iron, such as old horse-shoes, nail stubs and the like. In preparing the metal for the old-fashioned laminated steel barrels, a number of scraps were collected of various proportions, the clippings of saws, steel pens, and scraps of best iron, which were placed for some time in a shaking barrel for cleansing, and then hand picked, in order that any pieces which had the appearance of cast iron might be removed. They were then cut into pieces of the same size, melted together, gathered into a bloom, and the mass placed under a tilt hammer, welded into a block of iron which was immediately rolled into bars. The bars were then cut into regular lengths, and the required quantity laid together and fastened into a faggot, this faggot was again heated in the furnace and hammered and rolled into rods of the size required by the barrel welders. The supply of fine old scrap does not now meet the demand, so at the present time the metal for gun barrels is made from a mixture of the best iron ores. The iron is made into rods, and subjected to hammering and rolling, which condenses the metal and increases the ductility and tenacity by elongating and densifying the fibres. The faggots are heated and welded seven times during the process of manufacture of the best barrel metal. The iron for the manufacture of gun barrels is made in square rods of various thicknesses for the best barrels, and in flat rods for plain twist or scelp barrels. To give the Damascus figure the square rods are first twisted, the operation being carefully overlooked to guard against one portion being twisted more rapidly than the other. This process is repeated until the rod is perfectly twisted and a regular figure in the barrel insured. It is this twisting of the rods that makes the difference between a best barrel and a common one. All Damascus barrels must be made of twisted rods. Plain twist or scelp barrels are made from plain straight rods or ribands. It is the twist in the rods that cause the figure to appear in the barrels and all iron so twisted is called "Damascus," from the town Damascus, where a similar process was first practised for the far-famed Damascus sword blades. The prepared rod is either joined to other rods or coiled and welded into a barrel singly. Damascus barrels are made from one, two, or three twisted rods, and occasionally the Continental makers use four to six rods together. The Damascus barrels, as made in England, are usually manufactured from three twisted rods, which is quite sufficient to form a very fine figure in the barrel. Laminated steel barrels are twisted and the rods welded in the same manner as the Damascus, but the rods are composed of superiour metal containing a larger percentage of steel. The rods having been twisted and the required number welded together, they are then rolled at a red heat into ribands. The ribands are then twisted into spiral form, again heated, and the coil well hammered until thoroughly welded. The proportionate amounts of the different descriptions of metal in a barrel determine its quality. Best English Damascus and modern laminated steel contain 60 per cont. of steel. The amount of steel is determined upon before making the metal into faggots for the last time. If for scelp barrels, the strips of iron are twice the thickness of the steel, the faggots being formed of alternate layers of iron and steel. In single iron Damascus barrels the proportion of iron is not much less than the steel, and although not passing through so many processes as the best barrels, is still far superiour in quality to ordinary iron. In twisting the rods every care is taken to keep the edges of the iron and steel strips to the outside, for it is the twisting of the different metals that gives the various figures in the finished barrel. The steel being hard, resists the acids employed in the browning process and retains a white or light brown hue, whilst the iron, or softer metal, is so acted upon by the acid as to be changed into a dark brown or black colour. There is nothing in the process calling for any particular notice as far as fire risk is concerned. If in a suitable building there is no more risk than in a smithy, and in the whole course of my insurance experience I can only remember having one claim for a smithy being destroyed.

"Iron" should mean relatively pure iron as they knew pretty well how to make that. "Mild steel" shold mean non-heat treatable steel - around 0.2% carbon content. I don't think they were very sophisticated in identifying carbon content in heat treatable steels. Springs were most likely in the 0.7% - 0.9% carbon content region. The "bloom" was at welding temperature, so the steel was annealed, but the iron and steel chips were not totally melted. If melted, you would have wound up with simply lower carbon steel due to the inclusion of iron. The chips, wheter iron or steel, retained their identies.

Control of this process would involve the ratio of iron to steel, the grade of both iron and steel, chip sizes, uniformity of welding, and the amount of hot working and cold working of the rods produced from the bloom. Patterning should have been random, but probably got some orientation due to chip shapes and hammering.

I'd agree that terminology, materials, and measurements changed dramatically during the production period. I'd also bet that most patterns were "trade secret" rather than patented. Trade secrets tend to disappear with the last man standing.

Raimey - you aren't going to crack the speed of sound in a gun barrel. The powder gas is hot enough that you won't go that fast. Also, no amount of pressure will cause the gas to exceed Mach one (speed of sound for existing conditions and not a fixed velocity) in a straight wall bore. A convergent nozzle section can achieve Mach one, but you must add a divergent section to exceed Mach one. Excess pressure will only increase the density of the gas, but not the velocity, as you approach the speed of sound. Post back if any of that begs questions - I ought to be able to explain it.
Posted By: ellenbr Re: Damascus explained - 10/23/07 04:11 PM
So, pV = nRT has a larger effect than the velocity itself, which is at or greater than the speed of sound in a vacuum?

The pressure/volume/temperature relationship doesn't have a lot to do with sonic velocity. There is no sonic velocity in a vacuum as there is no sonic part - you have to have a fluid present to have an sonic pressure waves. No waves, not wave velocity.

Exactly Peter. W. Greener claimed to have invented Laminated Steel, but I've found no patent, nor did he name his invention. With his penchant for self-promotion (ie. Greener cross-bolt & Greener side safety) one would think 'Greener Laminated Steel' would be found stamped on his guns.

I see. I was referring to the nominal speed of sound and was thinking of the wave of a laser beam in a vacuum with an index of refraction of 1. My error. What is the max velocity that the expanding gas accelerates the shot charge down the tubes? Well, at the barrel/outside interface does the shot charge have the greatest velocity? I am interested as to how the speed of the whole lot of wad(possibly a little powder) & shot makes the transition from below the speed of sound to a velocity greater than the speed of sound. Doesn't the group velocity of the shotstring travel near or above 345 meters per second, or am I mistaken? Thanks for taking the time to educate me.

JOe: I quizzed Mr. Highsmith about the Brits Damascus & the impact of the Moor's influence on barrel types. His response was that I need to forgot researching such an unpopular & worthless topic and research something worth while like the Limey's Whitworth steel. And much like Jackie Gleason's response to a "germane to the situation", Mr. Highsmith said that the Moors were G**D*** Rednecks and don't bring them up again.

Ideal. Then that would equate Silver Steel Damascus to Laminated Steel and the old laminated steel would have been similar to 2 rib-band twist after experiencing the 3 ton forge hammer?

That's how I interpret Greener's statements going back to 1835.
BUT as much as I hate to bring this up, in the original Birmingham Proof House test of 1891, as published in The Field, BOTH "Laminated Damascus" (British and Foreign-no doubt Belgian) AND "Laminated Steel" are described.

A "twist" in the laminae of steel definition: "...it is advisable to state here that, so far as known, the strongest forged or twist barrel is the laminated steel now usually termed "stub-Damascus," made of three twisted rods to the riband.

The word laminated, as the designation of a gun barrel, arose from the fact that early in the last century thin strips, plates, or laminae of steel, piled alternately with iron strips or plates, formed the composite metal from which they were made. The differ from Damascus in so far as the iron and steel are differently arranged in the pile, so that instead of a decided curl in the figure there is only what may be termed "herring-bone" lines running spirally round the barrel from end to end. Technically, laminated steel is a name metallurgists apply to faulty steel. It has been used in the gun trade for more than half a century in quite a different sense, as here stated."

I re-read the portion of chapter X dealing with gun barrels. It seems that there are possibly 1/2 dozen laminated definitions.

History of Science and Technology in Islam






The Arabic Origin of Liber de compositione alchimiae


The Origin of Damascus Steel In Arabic Sources [1]

1. Introduction

The main function of this paper is to make available to historians generally a selected number of passages in Arabic medieval literature (some of which were hitherto unpublished) which bear upon ferrous technology. There are other numerous sources which are not cited here. Thus, this paper is not exhaustive in this respect. For each source, an English translation is presented followed by the Arabic text.

Thus, Section 2 below quotes al-Kindi on the location of steel centers, and Section 3 gives al-Biruni's description of Damascene crucible steel production. The following section from al-Jildaki describes what seems to be the production of pig iron and cast steel, and so on.

The review of sources concludes with Section 8. No attempt is made to draw general conclusions, except that the evidence adduced seems ample to demolish the commonly held notion that Damascene steel was produced only or mainly from Indian wootz steel, or that Damascus was not a center for producing steel. Section 8 locates iron mines in the Damascus region, and documents the persistence of the ferrous industry there down to modern times.

2. AI-Kindi on Sources and Centers of Production

Among the extant works of Abu Yusuf b. lshaq al-Kindi (fI. 850), "the philosopher of the Arabs", is "A Treatise (Addressed) to some of His Brethren Concerning Swords" رسالة إلى بعض إخوانه في السيوف The treatise contains much useful technological information. But we shall be content in this paper to give al-Kindi's classification of the various kinds of iron and steel from which swords were being made. The passages below have been excerpted from this treatise [2]

Natural and not-natural iron:

“Learn that iron from which swords are forged is divided into two primary or main divisions: natural (as mined) and not-natural (i. e. manufactured). Natural iron is divided into two divisions: shaburqan شابورقان and it is the male, hard iron which can be heat-treated قابل للسقي by its nature, and narmahin (narm-ahin), which is the female soft iron which cannot be heat-treated by its nature. [Swords] can be forged from either of these two kinds or from both combined. Thus, aIl kinds of swords made of natural iron fall into three kinds: shaburqani, narmahani, and those made of a combination of both.”

اعلم أن الحديد الذي تطبع منه السيوف ينقسم قسمين أولين: إلى المعدني والذي ليس بمعدني، والمعدني ينقسم قسمين: إلى الشابورقان وهو المذكر الصلب القابل للسقي بطباعه، والى النرماهن وهو المؤنث الرخو الذي ليس بقابل للسقي بطباعه ، وقد يطبع من كل واحد من هذا الحديد مفردا ومنهما معا مركبين. فجميع أنواع السيوف المعدنية ثلاثة الشابورقانية والنرماهنية والمركبة منهما.

Not-natural or manufactured iron or steel:

"Iron which is not natural (i.e. manufactured) is steel or fuladh فولاذ . 1t means the refined or purified المصفّى. It is made of natural iron by adding to it while smelting sorne (ingredients) for purifying it, and for decreasing its softness, until it becomes strong, flexible, susceptible to heat treatment, and until its firind فرند appears.” [3]

فأما الحديد الذي ليس بمعدني فهو الفولاذ ومعناه المصفا ، ويصنع من المعدني بأن يلقى عليه في السبك شيء يصفيه ويشد رخاوته حتى يصير متينا لدنا يقبل السقي ويظهر فيه فرنده.

Three main qualities of steel:

“This steel is divided into three divisions: the antiqueالعتيق, the modem المحدث , and the non-antique, non-modern. Swords may be forged from all these steels. Thus, there are three kinds of swords: the antique, the modern, and the non-antique, non-modern.”

وهذا الفولاذ ينقسم إلى ثلاثة أقسام إلى العتيق والمحدث والى لا عتيق ولا محدث وقد يطبع من هذه جميعا السيوف. فانواع السيوف الفولاذية ثلاثة: عتيق ومحدث ولا عتيق ولا محدث.

"Antique" means top quality steel:

" Antique is not related to time (or age) but it indicates the noble or the generous qualities, as when it is said "an antique horse" meaning a noble horse (of good breed). That (sword) which has the noble qualities is "antique", no matter in which age it was forged. At the extreme end of the "antique" is its opposite in meaning, I mean that (sword) which is deprived of the qualities of the "antique". That is why it was given an opposite name, i. e. modern, even if was forged before the time of `Ad [4]. Those (swords) which have sorne qualities of the "antique", but which are deprived of sorne of its qualities, are the swords which exhibit sorne of the qualities of the "modern". Therefore, these swords are given a name in the middle between both, and they are classified as non-antique, non-modem even if they are forged in ancient or modern times. Sword- makers called some of these swords "non-antique", and called some others "non-modern".

ولم تذهب من عتقها إلى الزمان بل إنما تذهب من عتقها إلى الكرم كما يقال فرس عتيق يراد به كريم. فما لحقته خواص الكرم فهو عتيق في أي دهر طبع. والطرف الأبعد من العتيق هو ضده في المعنى أعني ما عدم خواص العتيق فلذلك سمي بضد اسمه أعني محدث وان كان قد طبع قبل زمن عاد. وأما الآخذة بعض خواص العتيق وحارمة بعض خواصه فهي التي وجد فيها بعض خواص المحدث فسميت أيضا باسم متوسط بين الاسمين فقيل ليس بعتيق ولا محدث وان كان متقدم الزمان أو حديثه؛ فاختص الصياقلة لها اسم لا عتيق في بعضها ولا محدث في بعضها.

Three kinds of "antique" or quality swords:

“The antique are divided into three kinds. The first and best in quality of all is the Yemenite; the second is the Qal`i قلعي [5]; and the third is the Indian.”

فالعتيق ينقسم ثلاثة أقسام أولها وأجودها اليماني ثم ثانيها القلعي ثم ثالثها الهندي.

Swords forged from imported steel:

Some swords were called non-native غير مولّد. They were forged from imported steel. Some Khurasani swords for example were forged from steel imported from Sarandib; and this is the case in several other cities.

Swords forged from local iron:

“As for those native swords مولّدة, they fall into five kinds. Of these are the Khurasani, the iron which is produced and forged in Khurasan; the Basriyya, the iron of which is produced and forged at Basra; the Damascene, the iron of which is produced and forged at Damascus; the Egyptian, which is forged in Egypt. Swords in this category may be forged in other places like those of Baghdad, of Kufa, and a few other places, but are not attributed to such places because of their scarcity. These are all the types of swords which are made from manufactured iron, I mean from steel.”

وأما المولدة فتنقسم خمسة أقسام. منها الخراسانية وهي ما عمل حديده وطبع بخراسان. ومنها البصرية وهي ما عمل حديده وطبع بالبصرة. ومنها الدمشقية وهي ما عمل حديده وطبع بدمشق قديما. ومنها المصرية وهي ما طبع بمصر. وقد يطبع في مواضع غير هذه كالبغدادية والكوفية وغير ذلك من المواضع القليلة ولا تنسب اليها لقلتها. فهذه جميع أنواع السيوف المذكورة من الحديد المعمول أعني الفولاذ.

3. Al-Biruni on Damascus Crucible Steel

The next passage is from Kitab al-Jamahir fi ma`rifat al-jawahir الجماهر في معرفة الجواهر (A Compendium of Mineralogy( written by the celebrated savant, Abu al-Rayhan al-Biruni (973 -1048). Two main manuscripts were consulted. The first is Ms. Topkapi 2047 from Istanbul, and the other is Ms. Casiri 905 from the Escorial. Similarly, the book printed in Hyderabad was also consulted (Kitab al-Jamahir, edited by E. Krenkow, Hyderabad, 1936/37). Al-Biruni says:

“Mazyad b.`Ali, the Damascene blacksmith, wrote a book describing swords that were specified in al-Kindi's treatise. He commenced by dealing with the steel composition and the construction of the furnace (kur) as weIl as with the construction and design of crucibles, the description of (the varieties) of clay, and how to distinguish between them. Then he instructed that in each crucible five ratls of horseshoes and their nails should be placed, which are made of narmahin, as well as a weight of ten dirhams each of rusukhtaj روسختج , golden marcasite stone المرقشيشا الذهبي and brittle magnesia. The crucibles are plastered with clay and placed inside the furnace (kur). They are filled with charcoal and they (the crucibles) are blown upon with rumi bellows. each having two operators, until it (the iron) melts and whirls. Bundles صررare added containing ihlilaj (myrobalan), pomegranate rinds, salt (used in) dough, and oyster shells أصداف اللؤلؤ , lit. pearl shells, in equal portions, and crushed, each bundle weighing forty dirhams. One (bundle) is thrown into each crucible; then it (the crucible) is blown upon violently for an hour. Next, they (the crucibles) are left to cool, and the eggs are taken from the crucibles.”

ولمزبد بن علي الحداد الدمشقي كتاب في وصف السيوف الني اشتملت رسالة الكندي على أوصافها. ابتدأ العمل بنصاب الفولاذ وصنعة الكور وعمل البواطق ورسومها وصنعة أطيانها ثم أمر أن يجعل في كل بوطفة خمسة أرطال من نعال الدواب ومساميرها المعمولة من النرماهن ومن كل واحد من الروسختج والمرقشيشا الذهباني والمغنيسيا الهشة وزن عشرة دراهم ويطين البواطق وتودع الكور وتملأ فحما وينفخ عليها بالمنافخ الرومية كل منفاخ برجلين الى أن تذوب وتدور وقد أعد له صررا فيها اهليلج وقشر رمان وملح العجين وأصداف اللؤلؤ بالسوية مجرشة في كل صرة أربعين درهما يلقى في كل بوطفة واحدة. ثم ينفخ عليها نفخا شديدا بلا رحمة ثم تترك حتى تبرد وتخرج البيضات عن البواطق.

4. Al-Jildaki (commenting on Jabir ibn Hayyan) Discusses Pig Iron and Cast Steel

lt was found that Ms. no. 4121 of the Chester Beatty Library, contains a part of Kitab al-Hadid (The Book of lron) of Jabir ibn Hayyan, that is given in the course of a commentary by al-Jildaki (fi. c. 1339 -42). The following text from this Ms. is of great significance for the history of metallurgy:

“Chapter: Learn, brother, that it is your comrades who found (from founding, melt metal يسكبون) iron in foundries (especially) made for that purpose after they have extracted it (the ore) from its mine as yellow earth intermingled with barely visible veins of iron. They place it in founding furnaces designed for smelting it. They install powerful bellows on all sides of them after having kneaded (يلتّون) a little oil and alkali into the ore. Then fire is applied to it (the ore), together with cinders (الجمر) and wood. They blow upon it until it is molten, and its entire substance جسمه وجسده is rid of that earth. Next, they cause it to drop through holes like (those of) strainers, (made in) the furnaces أكوار so that the molten iron is separated, and is made into bars from that soil. Then they transport it to far lands and countries. People use it for making utilitarian things of which they have need.

As for the steel workers, they take the iron bars and put them into founding-ovens مسابك which they have, suited to their objectives, in the steel works. They install firing equipment أكوار into them (the ovens) and blow fire upon it (the iron) for a long while until it becomes like gurgling water. They nourish it with glass, oil, and alkali until light appears from it in the fire and it is purified of much of its blackness by intensive founding, night and day. They keep watching while it whirls for indications until they are sure of its suitability, and its lamp emits light; Thereupon, they pour it out through channels so that it cornes out like running water. Then, they allow it to solidify in the shape of bars or in holes made of clay fashioned like large crucibles. They take out of them refined steel in the shape of ostrich eggs, and they make swords from it and helmets, lance heads, and all tools.” (see Arabic text below)

From these two descriptions it seems safe to state that the first process describes the production of pig iron (or cast iron), and that the second one describes the production of cast steel from pig iron.

5. lron Foundries in Damascus in the Twelfth and Thirteenth Centuries

Reference to iron foundries in Damascus in medieval times can be found in Arabic literature. Thus, in the book $ubh al-a`sha (Cairo: Ministry of Culture) by al-Qalqashandi (d. 1418), when discussing government departments in Damascus during the Ayyubid dynasty (1171-1250), the foIlowing statement occurs (vol. 4, p. 188):

“Of these are several smaIl military departments شدود such as the department of foundries شدّ المسابك for iron, copper, glass, and others.”

ومنها ....شدود صغار متعددة كشد المسابك من الحديد والنحاس والزجاج وغير ذلك.

Then, (on p. 190), al-Qalqashandi speaks about departments of the civil service in Damascus and says:

“Of these is the civil department of foundries نظر المسابك and the executive in charge of this department is the counterpart of the officer in charge of the military department of foundries شدّ المسابك who was mentioned above when dealing with military officers (men of the sword). “

The History of Damascus City ناريخ مدينة دمشق (Damascus: Arab Academy of Science,1954) by Abu al-Qasim `Ali ibn al-Hasan, known as Ibn `Asakir (d.1177), mentions (vol. 2, p. 58) the sites of iron foundries in Damascus.

6. Distinction between lndian and Damascus Steels in Arabic Literature

Zayn al-Din al-Dimashqi al-Jawbari(d.1232) wrote his book A Selective Book on Revealing Secrets المختار في كشف الاسرار ( printed Damascus, 1302 H) as a guidebook on how to discover cheating methods adopted by various trades and crafts. Chapter eight is on "revealing secrets of manufacturers of arms ". The following passage occurs (p. 61):

“They have a prescription for a (good) cutting sword: Indian steel or Damascus steel is taken and a sword is made of these steels which is strong (thick) in the middle and thin at the edges, with evenness such that no place is stronger than the other. Then, if it is heat-treated with the above-mentioned water, nothing can oppose it.”

ولهم صفة سيف قاطع: يؤخذ فولاذ هندي أو دمشقي فيعمل منه سيف قوي الوسط رقيق الجوانب متساويا لا يكون موضع أقوى من موضع ثم يسقى من الماء المتقدم ذكره سابقا فانه لا يقف قدامه شيء .

The passage below shows that the term "Damascus steel" was current during the fourteenth century. The quotation is from a manual on quality control by Dia' al-Din Muhammad al-Qurashi, known as Ibn al- Uhkuwwa, (d. 1329). The book is Ma`alim al-qurba fi ahkam a-hisba معالم القربة في أحكام الحسبة ( ed. Reuben Levy, Cambridge, 1938; repr. Baghdad, Muthanna), p. 224:

“An honest and trustworthy (individual) from among them (the artificers) is chosen (as inspector). He prevents (them) from mixing steel needIes with (those made of) armahan (soft iron, narmahin) for, when sharpened, they may be taken for those made from Damascus steel. Therefore each quality should be separate from the other, and he should take an oath from the artisans to follow these regulations. ”

يعرف عليهم رجلا ثقة أميتا من أهل صناعتهم يمنعهم أن يخلطوا الإبر الفولاذية مع الارمهان لأنها إذا سنت جاز أن تختلط بالفولاذ الدمشقي بل يكون كل صنف منها على حدته ويحلف الصناع على ذلك.

7. The Firind or the "Damask" Pattern on Blades

All Islamic swords that were made from "Damascus steel" or from steels of similar quality showed the peculiar pattern that was referred to in Arabic literature as firind or "jawhar" فرند ، جوهر. The processes of producing steels in crucibles were practiced in Islamic lands mostly from native iron ores as we have shown above.

From al-Kindï's treatise, we learn that the "Damask" pattern or Firind الفرند or jawhar الجوهر is found in all manufactured steels. According to him, swords made from natural steels (non-manufactured, Shaburqan) have no pattern or "firind". When speaking about the firind of swords made from natural steel, al-Kindï states:

“These swords show no firind when treated with tarh [6] طرحor when treated otherwise, and aIl their iron is one colour.”

وهذه السيوف لا فرند لها في طرح ولا غيره وحديدها كله لون واحد

On the other band, aIl swords made from manufactured steel show the "firind" in varions degrees. Al-Kindi describes the "firind" or pattern of all types of manufactured steels and of swords produced in various localities in Islamic lands, and of Indian steel.

Al-Biruni in his above mentioned book (al-jamahir) gives a very interesting interpretation of the cause behind the formation of the firind or pattern in steels. It is due, in his opinion, to the incomplete mixing of two components of steel in the crucible: soft iron (narmahin) and its water (dus دوص):

"As to (iron) which is made from narmahin and its water which flows before it when it gets rid (of its impurities), it is caIled fuladh فولاذ (steel).

وأما المركب من النرماهن ومن مائه وهو الذي يسبقه الى الجريان عند التخليص فهو الفولاذ

Then he states:

“Fuladh (steel) in its composition is of two types. Either all that is in the crucible, narmahin and its water, is melted equally so that they become united in the mixing operation and no component can be differentiated or seen independently, and such steel is suitable for files and similar tools (and one may imagine that shaburqan is of such type and of a natural quality suited to hardening); or the degree of melting of the contents of the crucible varies, and thus the intermixing between both components is not complete, and the two components are shifted يتجاوز and thus each of their two colours (components) can be seen by the naked eye and it is called firind.” [7]

وحال الفولاذ في تركيبه على قسمين اما أن يذاب ما في البوطقة من النرماهن ومائه ذوبا سواء يتحدان به فلا يستبين أحدهما من الاخر ويستصلح للمبارد وأمثالها ، ومنه يسبق الى الوهم أن الشابورقان من هذا النوع وبصنعة طبيعية تقبل لها السقي؛ واما أن يخلف ذوب ما في البوطقة فلا يكمل الامتزاج بينهما بل يتجاوز اجزاؤهما فيرى كل جزء من لونيهما على حدة عيانا ويسمى فرندا.

AI-Biruni gives his definition of the two components of steel (which give rise to the firind) at the very beginning of the chapter on iron and he states:

“Narmahin is divided ...into two types. One is (narmahin) itself, and the other is its water which flows from it when it is melted and extracted from stones, and it is called dus دوص, in Persian it is called astah, and in the area of Zabilstan, ru رو, because of its speed of flow and because it overtakes iron when it is flowing. It is solid, white, and tends to be silvery.”

ثم ينقسم النرماهن ... الى ضربين أحدهما هو والاخر ماؤه السائل منه وقت الاذابة والتخليص من الحجارة ويسمى دوصا وبالفارسية استه وبنواحي زابلستان رو لسرعة خروجه وسيقه الحديد فب الجريان. وهو صلب أبيض يضرب الى الفضية.

Al-Biruni’s interpretation of the cause of the firind or pattern in Damascus steel is reminiscent of the modern interpretation of modern historians of metallurgy who were studying the secret of Damascus steel for the last two centuries.[8]

8. Iron Mines in the Lebanon and Anti-Lebanon Ranges

The Geographer, Shams al-Din Abu `Abd Allah al-Maqdisi (also known as al-Muqaddasi, d. c. 1000), in Ahsan al-taqasim fi ma`rifat al-aqalim أحسن التقاسيم في معرفة الأقاليم (Leiden: Brill, 1906; repr. Baghdad, Muthanna), p. 184, when speaking about iqlim al-Sham (i. e. Syria) states that there were iron mines in the mountains of Beirut.

وبه معدن الحديد في جبال بيروت.

In like manner, al-Idrisi (d. c. 1160) in Nuzhat al-Mushtaq fi Ikhtiraq al-Afaq نزهة المشتاق في اختراق الافاق (see Eilhard Wiedemann, Aufsötze zur arabischen Wissenschaftsgeschichte, vol. 1, p. 740) reports that iron ore in large quantities was being mined in the vicinity of Beirut and transported to all parts of Syria.

The famous travel account, Rihlat Ibn Battuta رحلة ابن بطوطة (Beirut, Sadir, 1964), contains a remark by the author (p.62) to the effect that when he stopped over in Beirut in 1355, iron was being exported from there to Egypt:

ثم سرنا الى مدينة بيروت ... ويجلب منها الى ديار مصر الفواكه والجديد

Dawud Ibn `Umar al-Antaki (d. 1599) in his Tadhkira تذكرة داود الانطاكي (Cairo, n.d., p. 111) defines iron and describes the manufacture of steel from soft (female) iron in crucibles. He states that iron originates from Sham (i. e. greater Syria), Persia, and Veniceز

ويتولد بالشام وفارس والبندقية

In the eighteenth century (between 1792 and 1798), the German traveller, U. I. Seetzen, in his Reisen (Berlin, 1854), Bd, 1, pp. 145, 188-191, reported that the ferrous industry in the Lebanese mountains was still flourishing. Operations involving mining, smelting, and the fabrication of steel implements were in full swing.

In the nineteenth century, W. M. Thomson, who lived in Syria, refers in his book The Land and the Book (London, 1886) to iron in the Lebanese mountains and to iron ore mining and smelting, which operations were still going on in about 1834.

In 1921, I. M. Toll wrote a paper on the Mineral Resources of Syria (Engineering and Mining Journal, vol. 112, 1921, p. 846) with a map showing the iron ore deposits. He describes the quality of iron ores and the locations of iron ore mining which was still going on in some localities. He states, however, that smelting of iron in the mountains of Lebanon came to an end in about 1870 due to scarcity of wood and fuel and the low price of imported iron.

9. Concluding Remarks

The selections presented above represent only a small portion of the Arabic sources bearing on the history of steel technology. Even so, they raise the question of how it came to be generally accepted that the role of Damascus was that of a commercial distribution center only.

The answer seems to be somewhat as follows. As the industrial revolution got underway early in the nineteenth century, European steel makers sought to emulate the quality of Damascus blades and that of the "wootz" steel then being imported into Britain from India. It was natural that their investigations should focus upon regions where the techniques were then known to be actively practiced, especially India. Thus, Syria and other Islamic lands came to be ignored. The literature on the subject of Damascus steel is considerable. The interested reader will find much of it referred to in Cyril S. Smith's A History of Metallography (Chicago: The University of Chicago Press, 1960). Curiously enough, Smith makes no mention of the work of Eilhard Wiedemann, who in Beitrage XXIII and XXV of Aufsätze zur arabischen Wissenschaftsgeschichte (Hildesheim - New York: Georg Olms Verlag, 1970) gives German translation of numerous passages from Arabic material.

Wow skatr-thank you!

So what do we (sorta) know about Laminated Steel?

From English Sporting Guns and Accessories by Macdonald Hastings - "The gunmaker Rigby of Dublin, made the first Damascus barrels; but they did not come into general use untill after 1825. Prior to that, barrels were twisted out of horse shoe nails. Damascus barrels (only remotely to do with the place called Damascus) were worked into their beautiful herring-bone patterns by the mingling of iron and steel. Even the new barrels were only reluctantly accepted by the sportsman." This may be the first description of Laminated Steel barrels.

The Gun, or a Treatise on the Various Descriptions of Small Fire-Arms 1st Edition 1835 by W.W. Greener
Discussed Silver Steel and Mr Wiswoulds Iron, the description of which suggests early Laminated steel.

The Science of Gunnery, as Applied to the Use and Construction of Fire-Arms, 1841, may be W.W. Greener’s description of his claim for inventing Laminated Steel - "I have had as high as three-fourths of steel to one of iron, and where proper attention is paid to clipping of the steel to pieces, corresponding with the (horse-nail) stubs, and properly mixing the whole (into a 'bloom' of molten metal), welding (in an air furnace) and forging by the heavy hammer, reducing by a tilt ditto, and rolling down to the…rod, a most excellent, tenacious, and dense body of iron is obtained; while, by cutting into lengths of 6 inches, bundling a number together, and re-welding them into a bar, you gain an increased density and tenacity…rendering it…considerably more powerfully strong than any explosive fluid ever yet compounded could burst…"

Shooting By Baron Thomas de Grey Walsingham, Sir Ralph Payne-Gallwey, Lord Charles Lennox Kerr, Archibald John Stuart-Wortley, Gerald Lascelles, Simon Fraser Lovat 1886
"Laminated steel barrels differ but slightly from those known as 'Damascus.' The former were first made by Mr. W. Greener (senior), of Birmingham, about 1850, and were composed of three parts steel and one part iron. At the present time the best English damascus, as well as laminated steel barrels, contain over 60% of the harder metal, and there is little perceptible difference between Damascus and a laminated Damascus barrel, as both are of very similar workmanship and materials.

The Birmingham Proof House Test of 1891 as published in The Field included barrels described as:
1. Belgian and English Laminated Damascus
2. Machine-forged English Best Laminated Steel, 3-Rod and 2-Rod
3. English hand-forged 3-Rod Best Laminated Steel

In the 9th edition of The Gun, William Wellington Greener stated that he used Best Silver Steel, but in earlier editions referred to Silver Damascus. He also compared ‘Old-fashioned laminated steel (75% steel), ‘Modern Laminated Steel' (60% steel), and ‘Laminated Damascus.’

Some c.1870s Parker Hammer Lifter barrels are marked "Twist" on the top rib, but are clearly laminated steel. The Parker 1899 catalog lists "Fine Laminated Steel" for Quality I & H hammer guns, which is a grade below the "Fine Damascus" used on Quality G guns. It is likely One or Two Rod "Laminated Damascus" of either an English or Belgian source.
The 1888 Colt Patent Firearms catalog also has a quality gradation from Twist to "Laminated" to Damascus and Hunter Arms used “Laminated Steel” on Quality No. 1 L.C. Smith guns 1892-1898.

Posted By: Rocketman Re: Damascus explained - 10/24/07 12:28 PM
Raimey - There are three distinct sets of gas involved in a gun discharge. So far, I have been speaking of the gas evolving from the powder burn. It is hot enough that the speed of sound in it will be higher than we normally associate with gun discharge velocities. The second gas set is the air in the barrel in front of the wad. It will be compressed by the discharge, but much will flow out of the barrel prior to the shot exceeding its sonic velocity. The third set is the air outside the barrel. It will have typical sonic velocity.

The shot in the barrel will acclelrate to some velocity based on pressure of the powder gas on the wad base, friction of the wad/shot to barrel, and back pressure of the air in front of the wad. The powder gas can't flow at supersonic speed without passing through a nozzle, but doesn't need to as it can flow fast enough at subsonic (for it) speeds to achieve the needed shot velocities. The air in front of the shot is simply pushed out and we know that its compressive pressure is less than the pressure of the powder gas as shot loads continue to accelerate in long barrels. As the shot load exits into the ambient air, it may well be above the sonic speed of that air. Remember, sonic speed depends on temperature of the gas (air). As the shot charge exits the muzzle, a sonic shock wave will form on the bow of the charge and will trail away from it until the charge drops below sonic velocity. Muzzle velocities for shotguns typically range from 900 fps (slow) to 1500 fps (very fast). Typical sonic velocity of ambient air at the earth's surface is around 1100 fps.

How fast? Well, as I recall the limit for powder gas in a barrel is around 10,000 fps. If you need to go faster, you need a rocket or a rail gun.

Again, if that is not clear, ask questions - I should be able to explain this.
Posted By: ellenbr Re: Damascus explained - 10/24/07 01:51 PM
Excellent description. You must be a Rocket Scientist as I had many post grad classes with folk destined to work in that area for MICOM(ARDEC(?)) on Redstone Arsenal. So what is the peak temperature in the barrels & is it a linear or non-linear relation to the sonic velocity? Last, typically, where will the shotcharge experience the highest velocity(1/2 way down the tube, 3/4s the way, just outside the tube)?

Kind Regards,

Raimey
rse
Posted By: Rocketman Re: Damascus explained - 10/24/07 02:08 PM
The peak temperature will be within the shotshell hull and will occur during the time of peak pressure. The pressure will peak within the first couple of inches of shot travel; usually early within this period. Shot acceleration is directly tied to pressure, so the peak acceleration will be very early in the shot travel. Peak velocity, however, will occur at the muzzle as the shot continues to accelerate all the way down the barrel; at least for useful barrel lengths. The acceleration is down to around 20-40 additional fps in the last few inches. If you were to make a long enough barrel, the friction forces and air back pressure would eventually equal the force of the powder gs pressure and the shot would stop accelerating; longer and the shot would actually slow down.

Speed of sound in a gas is typically related to the square root of the temperature; higher temperature equal higher speed of sound. So, it is non-linear.
Posted By: ellenbr Re: Damascus explained - 10/24/07 02:33 PM
So, the first derivative of velocity has a practical application almost everywhere even, in the realm of hunting/shooting. Back to a Damascus type question: will the effect of the shotstring/wad reaching the sonic velocity at the muzzle have any different effect on Damascus versus fluid steel, for useful barrel lengths? Thanks for your time, Rocketman.

"So, the first derivative of velocity has a practical application almost everywhere even, in the realm of hunting/shooting." Yes, indeed and boy howdy it does!

The first appearance of a sonic shock wave is outside the muzzle, so there is no influence on the barrel, whether steel or damascus. Good question, IMO. Questions?
Posted By: ellenbr Re: Damascus explained - 10/24/07 03:00 PM
Rocketman:

Excellent, excellent exchange of information of my rambling questions and your precise, descriptive answers. I was deeply curious as I am trying to develop a particle model of the shotstring exiting the tubes. Currently, Roster seems to be a hot topic, but I had quizzed him and he inferred that it would be quite difficult. Many Thanks.

Kind Regards,

Raimey
rse
Posted By: Rocketman Re: Damascus explained - 10/24/07 04:35 PM
Thank you for the kind words. Glad to share any info in my posession.

While I agree with Roster that your model would be difficult, let me add a bit of fuel to the fire. IMO, shot acts as a fluid in the choke constriction. That is, it is experiencing internal pressure due to the powder gas pressure behind it and the pressure of the air being forced out of the barrel. The shot can't support shear forces, but is confined by the barrel. As it exits the muzzle, the shot pieces "push off" of each other as the relieve the pressure they are under. Some of the "push-off" is in a sideways direction and causes pellets to depart with a small sideways velocity, along with their axiel velocity. This sideways velocity is what we see as dispersion. Further, the air trapped within the shot column is pressurized and expands as soon as the shot clear the barrel. Some of the expansion creates a "sideways" wind that also imparts some sideways velocity to the shot pieces.

Now, the good part. When a fluid flows through a constriction, such as a choke cone, the velocity must increase to maintain mass flow rate. The increase in velocity comes at the expense of pressure; the pressure drops. The drop in pressure reduces the pellet to pellet push-off and the "sideways" wind. Therefore, dispersion is reduced. We know that the velocity of the shot charge is incresed by about 1 fps per 0.001 of constriction. So, the increase in velocity is confirmed.

That could be helpful in your model.
Posted By: ellenbr Re: Damascus explained - 10/24/07 06:21 PM
Once again, great info. That confirms what I had in mind. The front little speed demons who take the brunt of the cone are pushed to the wayside to the outer portion of the pattern in the fringe area and begin to lag behind with a slower individual velocity. And what you've described would account for the change in the traverse direction as opposed to the longitudinal. I haven't replicated Mr. Brister’s experiment just yet. Fluids, thermo, etc. will yield a very complex model. The only thing missing is plasma.

I contacted the German Gun Collector's and inquired for any information they may have gathered for German sources of damascus or any Germanic centers that may have produced them.
They very kindly responded, with correspondence from Axel Eichendorff responding to Dietrich Apel.

In part, here is the response:
Quote:

...Suhl, Ferlach, Brescia, Eibar and you name them, some smithes tried their hands in forging damascus barrels, bur few progressed beyond simple twist patterns.

...H. Anschuetz in 1811 claimed Suhl made damascus "equal to any else in the world", but he also wrote to promote Suhl gunmaking!

....Zimmer: Die Jagd-Feuergewehre,1877, p.15:
"figured damascus is predominantly forged in the villages on the banks of the river Vesdre between Liege and Verviers and is shipped from there all over the world.
In other gunmaking places mostly only lower qualities are produced, in Suhl for instance only simple twist barrels are produced, the better tubes without exception are bought in through Liege."

....There is precious little literature on the anonymous damascus Smithes.
Still the best is a series of articles by Manfred Sachse, himself an accomplished damascus master smith, published in the DWJ from 1978-1982.
To find out something about the individual smithes and their families, you will have to delve deep into the archives of the respective towns.


Once again the name of Manfred Saches surfaces.
So we have some dates with some more possible lines of research that will need to be followed...

Found another neat on-line book with a perspective other than Greener's

Shooting Simplified By James Dalziel Dougall 1865
http://books.google.com/books?id=BkACAAAAQAAJ&dq=w+greener+barrel+patents

A variety of iron termed “silver steel” is preferable to all others.
(Unfortunately there is no description of the production process)

It will at once be seen that the necessary time taken by three workmen in this cold-hammering process very much enhances the value of fine barrels. It is in this part of the process that the continental workmen are deficient…We have great faith in English pluck and muscle. No foreigner strikes a blow upon the anvil like your English workmen…

p. 18 There are various kinds of flaws in barrels, such as “cracks”, “sand holes”, and what are technically termed “grays.” They are those little specks in the iron…from rust showing more upon them than upon the smoother surface.
(What follows is a discussion of the various barrel flaws)

Silver Steel
http://simple.wikipedia.org/wiki/Carbon_steel

Quote:
Silver Steel or high-carbon bright steel, gets its name from its appearance, due to the high carbon content. It is a very-high carbon steel, or can be thought of as some of the best high-carbon steel. It is defined under the steel specification standards BS-1407. It is a 1% carbon tool steel which can be ground to close tolerances. Usually the range of carbon is minimum 1.10% but as high as 1.20%. It also contains trace elements of 0.35% Mn (range 0.30%-0.40%), 0.40% Cr (range 0.4%-0.5%), 0.30% Si (range 0.1%-0.3%), and also sometimes sulfur (max 0.035%) and phosphorus (max 0.035%).

Posted By: ellenbr Re: Damascus explained - 10/27/07 01:48 PM
With Mr. Chambers post on "America-Made Damascus", he notes p. 220(which I assume is the same in the 9th edition) for barrel info. There "The wire twist barrels - not an imitation of the figure of coiled wired-were made by Barrois of Paris at the end of last century" with Barrois & Marolles, who seems to have written a text-English translation in 1789, both being noted. William Dupein had a twist gun barrel patent in 1798. And "In 1806 J. Jones patented a method of making barrels from scelps or strips coiled a mandrel so that the edges overlapped, and then welded together at the edges of the strips. Stub barrels, made from old horse-shoe nails, were greatly in vogue at the commencement of this century." A process different from the ones in Spain or France. "The horse-shoe nail stub barrel was the first attempt to produce a figured barrel in England." "Scelp or plain rods were first twisted, afterwards the strips of the horse-shoe nail iron were twisted in like manner; and the introduction of Damascus iron followed shortly afterwards(1820)." Mr. Wiswould and Mr. Adams, both of Birmingham, were given credit.

Posted By: PeteM Re: Damascus explained - 11/01/07 02:47 PM
I am going to "cross post" this here, I already posted some of it to the American Damascus thread.

Charles Semmer's "Remington Double Shotguns". He has a chapter, though short, on damascus. Pictures of such items as Boston, Boston SJ, Washington, Ohonon, Chine damascus are all there. I have not gone over every b&w picture in the book, but he identifies a good number of patterns. The Remington Museum has a "Salesman's Rod" with sections of various damascus patterns on it. Each was clearly stamped as to the type / figure.

In that chapter Semmer suggests an interest thing. This is not primary source, but more of reminisce of Del Grego. Del Grego claimed that he remembered old time Remington employees talking about making damascus barrels and what hot work it was. Semmer suggests that Remington was not buying finished or rough tubes, but rather forged damascus billets. He further suggests that they may have had an American source.

Again, none of this is primary source and much is speculation on the part of Semmer, I believe. But it does cause me to think. Were there American sources for such a product? Were the British or Belgians exporting these? If there was a source, it would be almost impossible to trace without company records.

Certainly every American gun maker I have looked at in any depth employed a blacksmith or two. Was this part of their duties, at least in some companies?

"Game Guns & Rifles", Richard Akehurst:

Quote:
For instance it was not possible, at an economic cost, for London makers to forge their own twist barrels; W. Fullerd, of Clerkenwell, was the last in London who specialised and excelled in the art, carrying on the unequal struggle until his death in 1833.
....
William Fullerd of Compton Street, Clerkenwell and Charles Lancaster of Tichfield street...supplied leading gunmakers, such as John and Joseph Manton and, in his early years as a gunmaker, James Purdey.
After this the trade moves to Birmingham. He also Lancaster as finisher who would purchase the tubes from Birmingham, bore and file them and sell them to the London trade. Fullerd would produce the barrels from start to finish.

Akehurst describes and names the type of steel used to make twist barrels. From best to worse: 'Stub Damascus', 'herring-bone', 'Threepenny skelp', 'Twopenny skelp' or 'Wednesbury skelp' and finally 'Sham damn skelp'.

Posted By: PeteM Re: Damascus explained - 11/10/07 10:34 PM
I received my copy today of "Damaszener Stahl: Mythos, Geschichte, Technik, Anwendung" by Manfred Sachse. This 1989 13"x11" book of 253 page is devoted to Manfred's research into damascus history and it's production. Most of this well indexed book is about bladed weapons. He does, however, have a chapter exclusively on damascus barrels. Manfred is the only publish modern researcher on the subject who has spent considerable time at the avail. In addition, he set up a forge where he produced damascus faggots weighing from 3 to 5kg and even produced some as large as 1.5 tons. He has experimented with producing most of the damascus types and patterns he has observed.

Some interesting bits from the book.

In 1863 near Nydam, Denmark 2 ships were found buried in a bog containing damascus swords from the 4th to 6th century.

Francois Clouet (1751-1801) director of the Daigny steel works in France actively recruited workmen from Liege and Franchment to aid in the production of damascus barrels.

In 1798 William Dupein in England was developing a process for damascus production. The work was carried on by J. Jones who received a patent in 1806.

In 1804 Nicolas Bernard was producing damascus barrels in Versailles.

Anton Crivelli of Milan (circa 1822) was working with damascus barrels. He wrote a paper in which he mentions Nicholson, O'Reilly, Wilde of Sheffield and Clouet.

In 1828 Anossov of Russian became a major producer of damascus barrels.

In 1829 Cavaliere de Beroaldo Bianchini writes a paper about damascus barrels from Vienna.

He also mentions Juan Sanchez De Miruenna of Spain as being a producer.

He identifies the later 19th centers of production as Liege, Birmingham, St. Etienne, Suhl and Brescia. In 1906 Liege produced 850 tons of damascus barrels. Of this there were enough to make 156,000 damascus sxs shotguns.

While Liege became the center of damascus barrel production, Solingen equaled Liege as the center for damscus hilted weapons.

An observation from Sachse. Gas or Oil fired furnaces are a waste of time for damascus production, as they result in high levels of decarburization.

He defines something called "Concealed Damascus". Apparently the surface is ground until no texture or "water marks" remain.

By the way. Thanks to Doug Mann who recommended this book back at the begining of this thread. It took forever to find a copy

We have seen these images as graphics...
As soon as I get a chance, I will update these with better images. These are pictures of actual billets being assembled and formed.













The question in my mine, has been, what became of the manufacturing resources in Nessonvaux once Belgium lost it's dominance in the firearms industry. Here is part of the answer, Imperia Nessonvaux.

Earlier in this thread, there was a discussion of patents related to damascus. This patent was referenced

WILLIAM ROSE of Halesowen, England
39174 - IMPROVEMENT IN THE QUALITY AND ORNAMENTATION OF METALS
Issue date: Jul 7, 1863

Robert made a comment about machine production of damascus. Here is the segment he was referring to:

I took another look at the Ethan Allen patent, 48249.
http://www.google.com/patents?id=hTIAAAAAEBAJ&dq=48249&jtp=1

It finally dawned on me that Allen is doing something very different. Figiel shows this same technique, of splitting a solid damascus cylinder, but states that it was used during the 17th century in India.

So, Allen is re-inventing this ancient technique. One that was never used in 19th century Europe. It is truly a shame that significant production was not achieved by Allen.

Earlier in the thread Daryl H made mention of "Espingarda Perfeyta" or in English "The Perfect Gun" which was 1st published in 1718.

This is the original cover. The book is written by 3 brothers who dedicate the work to King John 5th of Portugal.


Here is a plate from the book showing workman making barrels.


They describe at least 2 methods for making barrels. The first involves a twisting of metal of various gauges to form the barrel. They also describe the "Catalan" method of spiral wrapped barrels. Two men work on the same piece-the authors stress the negative effects on accuracy of working at this strenuous trade while tired-and the tools of the trade are scattered on the ground, as well as some partially finished section. Great care is emphasized to produce the strongest barrel possible to with stand very stout loads.

A couple of thoughts. 1st this is after the siege of Vienna. They make mention of procurring steel from various city states through out Europe. 2nd Portugal would have been a natural setting for this transition of technology from the Isalmic world.

This is prior to the siege of Vienna. So Hartmann is not making copies of captured arms. Elgood is unclear as to whether or not damascus barrels were being produced in Ferlach. Hartmann is nearly 65 years before Liege was producing damascus. Both Liege and Ferlach lost their lead in the manufacturing of firearms about the same and for the same reason, namely the Napoleonic wars. After the formation of Belgium and Independence was declared, Liege once again resumed it's old production volumes.

Pete, the illustration of the Damascus being made in Portugal is interesting . It shows the various gauges and tools used .
Posted By: PeteM Re: Damascus explained - 11/29/07 02:11 PM
Daryl,

Yes it does. The brothers seem very intent on communicating the importance of those gauges. They talk about them quite a bit and went so far as to have them illustrated as you point out.

Language becomes confusing as I dig further back. They seem to use "Catalan" as their term damascus barrels. Others site this book and use Catalan to denote the locking mechanism. Certainly when referring to Eibar, Catalan is used for their (Spanish) enhanced flintlock. Actually the term Misquelet is used to describe the type of firearm being produced by some.

I am still not clear at what point the Italians come into this picture. They were certainly a player at this early stage. Just can't find enough documentation yet. There is a book, "Brescian Firearms: From Matchlock to Flintlock - A Compendium of Names, Marks & Works Together with an Attempt at Classification" by Nolfo de Carpegne that may be of some help.

I just have to be careful to not get caught up by lock development.

This may be of interest to you.
from the book "The Gunsmith's Manual" 1883

"Gun-Barrels -Best Materials for.- The barrels of the finest and best guns, either Damascus, or other steel, or iron, are formed as made in Europe and England, of scraps of iron suited to the purpose, and selected with great skill and the greatest possible care. These scraps, which are usually bought up about the country, are placed in what is called a "shaking tub"-a vessel which is violently shaken and rocked about by machinery or otherwise(depending on the particular locality)for the purpose of scouring and brightening the scraps. This done, they are carefully picked over by adepts, who cull out the unsuitable pieces. So rigid is the culling that it often happens that out of a ton of scoured scraps not more than one hundred pounds weight of them are chosen as suitable for going into the best barrels.

Among the scraps usually thought to be best are old chains that have been used for many years, the wear and rust of time having left only the best elements of the iron. The Damascus steel, which has attained to so high a reputation, got it by being manufactured out of old coach springs. Of course it is not all made of coach springs now, but it was in years ago; agents then travelled all over the country hunting and buying them up, paying a much higher price for an old broken spring than a new one would cost it's owner.

On Making Gun-Barrels.-The selected scraps to be worked into gun-barrel material are cut into small pieces and thrown into a furnace, where they are exposed to intense heat until fused,after which they are brought forth an adhering mass and placed under a hammer, which drives them together and forges them into bars. The bars are next rolled into thin plates, and then cut into strips twelve inches long and six inches wide. The very best guns are made of a combination of iron and steel. Both materials having been rolled and cut into sheets of exactly the same size, these sheets (one-fourth of an inch thick) are piled upon each other alternately to the number of thirty, and subjected to a welding heat; they are than driven together under a five-ton hammer into a consolidated slab. The slabs so formed are next worked down into one-fouth inch square rods. the more the material is hammered and worked the better it is. The rods are next twisted until they present the appearance of a strand of rope, some rods being twisted to the right and others to the left. Two rods with opposite twist, are heated to the welding degree, placed upon each other, and rolled together; they are now in a narrow slab, presenting that fine curl of "grain" peculiar to the damascus, or that beautiful wavy figure peculiar to the laminated steel,as the case may be. The next operation is to coil one of these slabs around a mandrel in a spiral form, and weld it securely under the blows of hand-hammers. It is now a gun-barrel in the rough.

Finishing and Proving.- The rough barrel goes from the welder to the borer,where it is put through the process of "rough boring." From the "rough borer" it goes into the hands of the "fine borer"
who bores it out smoothly and to near the size it is to be when finished. Another operator then takes it in charge and dresses it to smoothness externally, then the "tester" takes it and dips it into strong acid, which soon shows any imperfection in either twist or welding that might exist. If not perfect, it is sent back to be worked over; if all right, it passes to the next department, where it is straightened inside. This part of the work is governed entirely by the eye, and hence demands the services of a workman of great skill, and experience.

Having been "passed on" by the "staightener", the barrel goes to the "turner", who turns it in a lathe until the outside is true and correspondingly straight with the interior, and is exactly of the required weight. If the arm is to be a double-barrel shotgun, the barrel next goes into the hands of a workman who joins it to another barrel with the utmost nicety; to attain which, levels and other suitable instruments are brought into requisition, Like the man who staightens the bore , the man who joins the barrels must be a workman of great skill.

The next operation is to braze on the "lumps;" then next in order , the ribs are put on. Now comes the "proving." The rear ends haveing been securely plugged, they go to the proof department, where is placed into each barrel fully four ordinary charges of gunpowder; then, atop of this, a wad of strong brown paper, rammed securely down, then a leaden bullet large enough to exactly fit the bore, and then another wad of brown paper. The charge is fired, and if the barrels stand the ordeal unfazed, they are ready to be fitted to the action; otherwise, they go back to be worked over. In some houses the "proving" is done before the barrels are joined together."

Thanks Pete! It's likely the gun writer guys were as guilty then as they are today of repeating the same information from previous sources, but every addditional bit adds to our fund of knowledge.

"The selected scraps to be worked into gun-barrel material are cut into small pieces and thrown into a furnace, where they are exposed to intense heat until fused, after which they are brought forth an adhering mass and placed under a hammer..."
This is additional confirmation of the formation of the 'bloom' (which Pete M previously illustrated and which jOe has trained his pup to produce ) as the first step in the production process.
Posted By: PeteM Re: Damascus explained - 11/30/07 05:47 PM
Here are some early examples.... A Greener Pinfire. I suspect a few horse nails got used here.






This maybe the oldest European produced damascus example that I have seen so far. A French double flintlock. On this gun Etienne, Brevette, 1000 Francs and Morian all appear. I believe the only way to truly date this example is by the locks.







Notice the "lack of control" in both examples. The later Greener gun showing more "control" than this very early (circa 1790) French gun. But neither shows the control that we see in last quarter of the 19th century nor the extreme control that is achieved in the early 20th century, when names could be incorporated in the welding.

The French gun has very obvious Islamic influence in the production of the damascus. They did not have the same sources of steel as the Islamic makers did, so they adapt the technology. While not on a par with high end Islamic produced damascus, (better, ie, more technically refined barrels had been produced in India at least 100+ years earlier) this is still a very respectable effort.

I am still searching for the "turning point". The point at which carefully arranged billets of known material are arranged and worked to produced a specified product. The exact "turning point" may be lost to history.

PeteM,
When Oscar was alive and often used to post examples of his work here, I had a pretty good quality colour printer. The quality of his work was so outstanding that I got into the habit of printing off everything that he posted here. I was also playing around with refinishing some scrap barrels as a learning experience. I corresponded directly with Oscar about the process on several occasions. He was good enough to e-mail some colour photos of his work to me which may or may not have been published elsewhere, I really don't know. This was before I retired and as I had a commercial-duty laminator in my office at the time, I laminated all of that stuff, as well as scanning, printing, and laminating his series in DGJ. I have all of that stuff set up in a 3-ring binder. I don't think that the lamination would interfere with re-scanning what I have but the process would be lengthy, the file huge, and when completed, I have absolutely no idea how to post it here.

Ron: thanks to Dave Miles, I have some of Oscar's stuff on the Damascus Barrels album http://www.picturetrail.com/gallery/view?p=999&gid=16082038
My primary interest is in identifying the named damascus patterns, and the Belgian makers who produced the barrels used by US gunmakers.
Did Oscar have a file of London, Birmingham, Boston, Chine, Oxford, etc.? I'm especially interested in examples of 'Leclerc', 'Parisien', and named English damascus patterns. Thank you.

I find them crawling on the leaves. Drew dissects them, names them and put 'em on the shelf. (Hmm, sounds like he does all the work.)

Any insights you can offer from Oscar's research or your own are most welcome. Because of his great effort, I think we have made some progress.

My Rosetta stone is different than Drew's. I keep looking for the 1st documented maker who was assembling billets to control the final product. I think it is 6 to 5 that it occurred in Liege or St Etienne, but have no hard data at this time.

There is still more to come about the Islamic and Hindu origins...

Posted By: PeteM Re: Damascus explained - 12/04/07 04:22 PM
I should add the following information. We know that in 1771 Jean Jacques Perret published "L'Art du Coutelier". In it he describes the process of twisting ribbons. Many of the tools shown resemble what is later seen in the damascus barrel shops. There is a partial English translation at:
http://damascus.free.fr/f_damas/f_hist/perret.htm

There is no indication that he was able to control the look of the final product.

Also, Verhoeven and Pendray have recreated the process of recreating damascus blades. This is very similar to the work of Manfred Sasche. Here is an article that they published some years ago. Interesting microscopic picture is included in the article.

"The labor bestowed upon the manufacture of (Stub Twist) barrels was exceeded alone by that of the operatives of Damascus arms; and to such an extent was the hammering of the lusty smith carried, that it was not unusual for a mass of stubs, weighing from forty to fifty pounds, to be reduced by repeated beatings to a rod sufficient only to make a single barrel. By this long and arduous process the utmost ductility, tenacity, and purity were acquired, which rendered these (barrels) superior for safety and shooting-powers…"

Another hidden treasure discovered. The most detailed description of 'machine made' Damascus, with an explanation of the edge welding by "jumping" and mention of using two different tube segments for breech and "fore part."

http://books.google.com/books?id=inQCAAA...rjiY4#PPA335,M1

A. - Damascus metal is a mechanical mixture of steel and iron.
B. - This mixture is affected in the following way: A number of small this sheets of iron and steel, being placed alternately – are firmly wired or boxed together, heated in a furnace, and welded into a solid mass.
C. – The mass is then rolled out into long thin square bars or rods.
D. – The rods are then cut up into convenient pieces.
E. – Each piece is then heated and placed in a machine, in which one end of the piece is fixed, and the piece is rotated from the other end – the result being that the piece is twisted or corkscrewed very finely.
F. – The rods are rolled of various thicknesses, according to the number of rods in the particular barrels to be made. The finer the barrels are required, the smaller is the diameter of the rods, and the greater the number of rods required for a barrel.
G. – Two, three, four, or six rods are then taken, and are heated and welded together at the sides. Thus is made a flat strip, a little more than two, three, four, or six times wider than a single rod.
H. – Damascus barrels are made usually in two parts, fore part and back part, the back part being made of thicker metal than the fore part.
I. – This is done to avoid having to roll the strip taper from end to end, and to enable the welder to “jump” the barrel more powerfully than he would be able to “jump” a full length barrel.
J. – The strip is heated and rolled into a ribbon (ribband).
K. – This ribbon is cut into convenient lengths, one length sufficient for a fore part or back part, as the case may be.
L. – The ribbon is then (either with or without being heated) twisted round a round rod (mandrel) in a machine, and thus formed into a spiral tube.
M. – The spiral tube is then heated and welded by “jumping” the edges of the spiral together and hammering round the sides. This process is generally effected thus: an iron rod is inserted into one end of the spiral, and spiral placed in furnace, and when heated sufficiently, the welder withdraws the spiral from the furnace by means of the rod, and places it horizontally under a specially-made trip hammers, and “jumps” it hard vertically on an iron block let into the hearth floor, in order to force the edges of the spiral together. The hammering and “jumping” are repeated alternately as many times as required. The spiral is thus made into a rough tube. The tilt-hammer is not always employed; hand-made barrels being made by a welder and one or two strikers using welding hand-hammers.
N. – The two tubes, fore part and back part, are then heated at their joining ends and welded into one, and they then form a finished rough tube.
O. – It will be seen that (1) The essential factor of Damascus is steel. (2) That the various processes are effected with the object of interlacing the fibres of the metal and directed their length round the barrel instead of in a line with the rest of the barrel; so that, should the barrel burst, the fracture may follow the direction of the fibres and be impeded also by the interlacing of the fibres and the two metals, instead of being from end to end of the barrel, as it might be in case the fibres of metal run in straight line with the length of the barrel. (3) A Damascus barrel is heated many times. (4) The welding surfaces (a) of the thin plates, (b) of the twisted rods, (c) of the spiral, (d) of the two tubes, back part and fore part, into one. (5) In each of these processes parts of the tube are liable to be over-heated and the steel in them then damaged. (6) In each of these processes small imperfections in the welding are possible and most often occur. Those defects are often invisible til the barrel is finished or nearly finished, and, although the barrel may be perfectly safe, they are unwelcome eyesores to both buyer and seller of a gun.

p. 70 Part III On The Manufacture of Fire-Arms, And Modern Improvements.
http://books.google.com/books?id=0XJeF_o...w3u60I#PPA70,M1


Starting on p. 87 Forging of Gun-Barrels
A description of Stub, Stub-Twist, Wire-Twist, Damascus-twist, Stub-Damascus, Charcoal iron, Threepenny skelp iron, Two penny or Wednesbury skelp, and Sham-damn skelp.
The most approved modern method of converting…(horse-shoe nails)…into (Stub-Twist) gun-barrels after carefully sorting and picking the, to see that no cast-iron or impurities are mixed with them, is first to put about half a hundred weight into a large cast-iron drum or cylinder, crossed internally with iron bars, through the centre of which a shaft passes, which is connected by a strap with a steam-engine, and the revolution of the drum actually polishes the nails by their friction against each other; they are then sifted, by which every particle of dust is removed. The steel intended to be mixed with them is clipped by means of large shears, worked by the engine into small pieces, corresponding in size to the stubs, and afterwards cleansed by a similar process. About 40 lbs. are thrown on to the inclined hearth of an air-furnace, where they are puddle or mixed together with a long iron rod, and withdrawn in a mass called a bloom, almost in a state of fusion, to be welded under hammer of three tons weight, by which it is formed into a long square block: this being put in, at another door of the same air-furnace, is raised to a bright red heat, and drawn out under a tilt hammer of a ton and half weight, into bars of proper size to pass the rollers, by means of which it is reduced to rods of the required size.
p. 95 Possibly a description of what was later termed Laminated Steel
For the finest description of (Stub-Twist) barrels, a certain proportion of scrap steel, such as broken coach-springs, is cut into pieces and mixed with the iron by the operation called puddling, by which the steel loses a considerable portion of its carbon, and becomes converted to mild steel, uniting readily with the iron, and greatly increasing the variegation and beauty of the twist. In whatever manner the iron may be prepared, the operation of drawing it out into ribands for twisting is the same. This is effected by passing the bars, while red hot, between rollers until extended several yards in length, about half an inch wide, and varying in thickness according to whichever part of the barrel it may be intended to form: these ribands are cut into convenient lengths, each being sufficient to form one-third of a barrel: one of these pieces is made red hot and twisted into a spiral form, by placing on end in the prong of an iron rod, which passes through a frame, and is turned by a handle, the riband being prevented from going round without twisting by means of an iron bar placed parallel to the revolving rod. The spiral thus formed is raised to a welding heat, and dropped on to a cylindrical rod, which being struck forcibly on the ground (called jumping) the edges of the spiral unite, and the welding is then completed by hammering on the anvil. The other spirals are added according to the length of the barrel, and the forging is finished by hammering regularly all over. The ends of the spirals should be turned up and united at each junction of spirals, to avoid the confusion in the twist occasioned by merely dropping one spiral on anther; but this is rarely done. Wire-Twist, of any degree of fineness, may be obtained by welding alternate laminae of iron and steel, or iron of two qualities, together; the compound bar thus formed is drawn into ribands, and twisted in the same manner as the preceding.
p. 96 The iron called Damascus, from it’s resemblance to the celebrated Oriental barrels and swordblades, is now manufactured in great perfection in this country, as well as in France and Germany, and may be varied in fineness or pattern to almost any extent, according to the various manipulations it may undergo. One method is to unite, by welding 25 bars of iron and mild steel alternately, each about 2 feet long, 2 inches wide, and ¼ of an inch thick; and having drawn the whole mass into a long bar, or rod, 3/8 of an inch square, it is then cut into proper lengths of from five to six feet; one of these pieces being made red hot is held firmly in a vice, or in a square hole, to prevent it from turning, while the other end is twisted by a brace, or by machinery, taking care that the turns are regular, and holding those parts which turn closer than others with a pair of tongs, the rod is by this means shortened to half it’s original length, and made quite round. If only two pieces are employed to form the riband, one is turned to the right, and the other to the left; these being laid parallel to each other are united by welding and then flattened; but if three square rods are used, the centre one is turned in a contrary direction to the outside ones, and this produces the handsomest figure. By these operations the alterations of iron and steel change places at every half revolution of the square rod composed of twenty-five laminae; the external layers winding round the interior ones, thus forming when flattened into a riband, irregular concentric ovals or circles. The fineness of the Damascus depends on the number and thickness of alterations; but when wound into spiral form, and united on its edges by jumping, the edges bend round and the figure is completed.

This was on the cover of American Rifleman, April 1960. It is identified as being produced by A. Mohiev of Liege, 1770-1780, an early fowling piece.




I believe this may show what can be considered as pattern welded damascus. In 1771 Jean Jacques Perret published "L'Art du Coutelier". In it he describes the process of twisting ribbons. Many of the tools shown resemble what are later seen in the damascus barrel shops. So are we looking at one of the earliest examples? Without seeing the full barrel, it is difficult to tell. Unfortunately, there is no other information about this piece.

Posted By: PeteM Re: Damascus explained - 12/16/07 02:04 PM
Drew,

Yes that is the gun I posted earlier. I believe that our "definitions" fail with a piece this early.

This is a an example of a Misquelet Lock. It was most likely produced in the late 1600's in Europe. It is a good example of the heavy trade that was occurring between European makers and the Ottoman empire. Very often the barrels would be acquired and the gun built around them. This one is a cheap knock-off of the period. Unable to acquire the damascus barrels. For more about this trade see, Robert Elgood, "Firearms of the Islamic World" and also Anthony North, "Victoria & Albert Museum Islamic Arms".





Pete

The misquelet lock was in use for a very long time. This is a much later example circa 1800, again made for "the trade" within the Ottoman empire. What appears to be a damascus barrel is in fact known as damascene. A technique that was used to decorate the barrel surface. It was often done using silver or gold. This one is another type of faux damascus. The damascene is attempting to duplicate crolle. This would have been done using "stamps" while the barrel was being worked in the forge. Manfred Sasche duplicates this technique in his book.





Some of books mentioned are difficult to obtain and certainly they are relatively expensive. Here is a decent on-line tome worth looking at:George Cameron Stone
"Glossary of the Construction, Decoration, and Use of Arms and Armor in All Countries and All Times", 1999.

"Definitions" for this subject are sensitive to time and culture. What we refer to as damascus was generally known as "watered steel"

One of the difficulties that has to be over come to produce damascus is controlling the output of the smelting process. Both steel and iron have to be produced to create damascus. This takes a high level of technology. We know that this level had been reached in Europe shortly after firearms were 1st introduced.

"Some Aspects of the Metallurgy and Production of European Armor"
By Craig Johnson, first published in the Armored Proceedings Symposium Notes, 1999.
Quote:
The processes for turning iron ore into a workable material were known throughout Europe, Asia, and the Orient since antiquity. The product that was normally produced was wrought iron and later cast iron. Wrought iron never achieved a fully liquid state. A furnace held in the 1100°C to 1200°C (abt 2000°F-2200°F) range would allow the reduced iron particles of the ore to coalesce into a mass with the majority of the silicates liquefying and draining away as slag. What remained would be a spongy looking mass called a "bloom," the refining of which was accomplished by heating and hammering repeatedly to drive additional slag out and close any voids, resulting in a bar or plate of wrought iron. Iron produced in this way consists of large ferrite crystals and some slag inclusions and would have to be carburized to achieve a steely state. This carburization may have been accomplished in the furnace by lengthening the time the bloom is left in, tempreture increases or increases in the ratio of fuel to ore
.....
Cast iron needs the reverse process to be usable as a steel product. The material needs to be reduced in carbon content and this is usually accomplished by passing air through a stream of the liquefied iron onto a charcoal hearth, known as a finery, or "Walloon Furnace". There is some conjecture that such a process was being used in the pre Alpine valleys as early as the mid 13th century. By the 15th C. the Northern Italian production centers were casting iron cannon, which may indicate the technology was available in previous centuries to manipulate liquid iron. This also may have been the process used in Styria. The method for decarburisation by forging together cast and wrought iron and allowing carbon diffusion to take place resulting in a steel material is described by Biringuccio in Pirotechnia (1540) though this would be a difficult proces to control. Some have thought this maybe the "Brescisian Process" but this was probably a finery of some sort that was misunderstood by Biringuccio. The "Brescisian Process"may have been a source for the large amount of steel needed by the Milanese armorers.

In "Principles: The Manufacture Iron & Steel" by I. Lowthain Bell, 1884, he states "In the work of Agricola, bearing the date of 1556, there is no allusion to the Blast-furnace; the only arrangement described for obtaining iron being a kind of Catalan hearth, in which the product, as we have already seen, is malleable and not cast iron. About 1618, as we learn from Dud Dudley's Metallum Martis, this unfortunate pioneer in the manufacture of iron was engaged in his attempts to substitute pit coal for charcoal;..."

And regarding Catalan furnaces: "No serious attempt has been made to revive in this country the obsolete and almost forgotten Catalan furnace-much less its more humble predecessor, the low hearth of Asia and of Africa."

"I have had no opportunity of inspecting such a furnace as that previously referred to, and described to me by Colonel Grant;"(Dr. Percy is also mentioned as a source) ... "Some Catalan furnaces, which I had an opportunity of examining in North Carolina, were near 3 feet from back to front...."

So what was North Carolina producing, rail?

And also, I found patent No. 9,999 - Thomas Warner, of Chicopee, Mass - Improvement in Twisted Gun Barrels-Patented September, 6th, 1853. Did he make barrels himself was was he employed by another?

Raimey,

Interesting material. I get lost in this long thread and often have to go back and search to see if a subject has been covered.
Thanks for digging up the Warner patent. He was briefly mentioned, but not his patent. This is a partial replay of an earlier quote.

From Fire-Arms Manufacture 1880. U.S. Department of Interior, Census Office.

Quote:
The earliest use of decarbonized steel or gun-barrels is generally credited to the Remingtons, who made steel barrels for North & Savage, of Middletown, Connecticut, and for the Ames Manufacturing company, of Chicopee, Massachusetts, as early as 1846. It is also stated that some time about 1848 Thomas Warner, a the Whitneyville works, incurred so much loss in the skelp-welding of iron barrels that he voluntarily substituted steel drilled barrels in his contract, making them of decarbonized steel, which was believed by him to be a a novel expedient. The use of soft cast-steel was begun at Harper's Ferry about 1849. After 1873, all small-arms barrels turned out at the national armory at Springfield were made of decarbonized steel(a barrel of which will endure twice as heavy a charge as a wrought-iron barrel), Bessemer steel being used until 1878, and afterward Siemens-Martin steel.

Some early "sources" can drive you mad. Given Lowthain Bell's statements and the official Government document, one would have no idea what Warner was really up to. I wonder if Mr Bell even knew of Ethan Allen's work or some of the barrels that had been made by Parker. But we at least have a clue that Warner was making barrels for a government contract.

Warner provides no drawings with his application: http://www.google.com/patents?id=PAxLAAAAEBAJ&dq=9999+Warner&jtp=1
At least they are not online. A couple interesting statements though from his application.

What a perfect description of the role that damascus played!
Quote:
The object of my invention is produce a barrel which for given weight of metal shall present greater strength to resist the explosive force of gunpowder, and which shall avoid the liability of imperfect seams along the length.

Then he makes a some what confusing statement;
Quote:
...take a bar of iron of suitable quality and size, after it has been sufficiently and equally heated twisting it in the manner of twisting a strand of rope until the required twist has been given. I then upset it endwise to compact the mass.

He would have had no way to know that he was duplicating a well known technique used by Islamic barrel makers. Figiel has illustrations of these solid bar barrels. The Islamic barrels makers were willing to absorb the waste to produce a stronger barrel. Exactly when wrapping a ribbon around a mandrel made it's appearance is still elusive.

By the way, where did you find a copy of Bell?

Thanks for the insight and I too was concerned that it was somewhere on a previous post on this long thread.

Bell- Elder's bookstore in Nashville. My father-in-law, until his passing in 2006, was a rare book collector. So, today while visiting my spouse's family, I made the rounds to the rare bookshops with the little time I had. I was reluctant to purchase it, but I couldn't pass up an original. I also picked up "Patent Office Report Part 1 1853" as well as "Report on the Commissioner of Patents for the year 1861." No photo on Warner's patent, just verbiage. Bell- it's going to take me a little time to scan thru it. But Bell covers all the processes you mention plus Krupp on removing phosphorous from pig iron.

Dr. Drew:

This is an additional post just for you. Bell-ref above-"It is believed that the most ancient method known for making steel is an invention of Hindoo origin. In its fragments of wrought iron, made in the rudest way direct from the ore, by means of charcoal, was melted in pots in the presence of vegetable matter. The resulting steel is known in the market as "wootz," and containing as it does nearly 1.75 per cent, of carbon, possesses great hardness."

"Many years ago I witnessed the manufacture of steel in Rhenish Prussia as performed in a small refining fire. The hearth was about 2 feet square, the fuel used was a mixture of charcoal with a little coke, and the material treated was the pig iron and spiegle-eisen of the country." ......" ...and the presence of manganese in the spiegel enabled the German manufactures of Siegerland to furnish a very high class quality of steel in the primitive appliances referred to."

Raimey,

Good for you on purchasing those books.

In the Catalan furnace (circa 700 AD) iron ore and charcoal were charged vertically in the top, resulting in a "loupe" or ball of iron which was "hooked out and hammered into a bloom".
http://www.tf.uni-kiel.de/matwis/amat/def_en/articles/steel_collector/early_progress.html

No clue if this type of furnace was still in use during the 19th century in the US. Why anyone would choose such an outdated method?
For more steel making links: http://www.tf.uni-kiel.de/matwis/amat/def_en/kap_5/advanced/t5_1_5.html

I just picked up: FIGHTING IRON, A Metals Handbook for Arms Collectors by Art Gogan. It should arrive in about a week.

I was thinking the other day. It would be great if some one developed a simple glossary for some of this. Between wootz, laminated, twist, Bessemer, damascus, etc some times my head spins.

Tors ou torches
Ruban tordu tin

Pointelle' twist

What the Belgians called 'Laminated' but was twist, but they also make true 'Laminated steel'
Maybe it would be better to just figer' out how they made the stuff

Posted By: PeteM Re: Damascus explained - 12/27/07 02:14 PM
Very good Drew. How do we begin to create definitions?

If I take a pile of scrap. Chop it up. Heat it red hot. Hit with a hammer, is that damascus? Didn't say I was wrapping it around anything. Didn't say I was making a barrel from it. What if the scraps are homogenous? No iron / steel mix. I want to say that the product from the above process is not damascus. But then, I have to throw out all wootz barrels.

So maybe it is damascus if there is a visible pattern?

More horse-shoe nail talk and possibly an answer as found in "Engines of War: ... " Henry Wilkinson(grandson of Henry Nock) - 1841 from one of Drew's last 1/2 dozen posts.

He mentions an arsenal in Dresden "where there is an old Buchse(u w/ double dot) during the time of Henry VIII which used pyrites on a matchlock. So, is there any additional info on the old arsenal at Dresden?

Engines of War:… - Henry Wilkinson -1841

“In order to make stub-iron, old horse-shoe nails, called stubs, are collected, then packed closely together, and bound with an iron hoop, so as to form a ball about ten or twelve inches in circumference; which, being put into a furnace or forge-fire, and raised to a welding heat, is united by hammering, and drawn out into bars of convenient lengths, for the purposes intended. This method is adopted for the locks, furniture, and breechings of all best guns, and is to a certaint extent practiced for barrels, … immense numbers of horse-shoe nails are imported from France, Holland, Sweden, and other parts of the continent, in casks containing from 16 to 18 cwt. each.” From here he describes the process of tumbling and cleaning the nails so that “every particle of dust is removed.”

Maybe the truth about horse-shoe nails:
“It need hardly be remarked, that the advantage to be derived from the use of the horse-shoe nails does not arise from any virtue in the horse’s hoof, as some have imagined, but simply because good iron is, or ought to be, originally employed for the purpose, otherwise the nails will not drive into the hoof; and the iron, being worked much more, is freed from its impurities, which can only be effected by repeated workings.”

“Stub Damascus is merely one square rod of Damascus iron twisted and flattened into the riband for forming the barrel.”

“Wire-twist, of any degree of fineness, may be obtained by welding alternate laminae of iron and steel, or iron of two qualities, together; the compound bar thus formed is drawn into ribands, and twisted in the same manner as the preceding.”

“The iron called Damascus, from its resemblance to the celebrated Oriental barrels and sword-blades, is now manufactured in great perfection in this country, as well as in France and Germany, ….”

He goes into detail of the number of bars for the riband that one be twisted opposite the other. If 3 are in order, the center is twisted opposite the outside two bars. And finally he states: “The fineness of the Damascus depends on the number and thickness of the alterations;

Google Tannehill State Park. In the seventies they rebuilt an old blast furnace and produced iron. The Tannehill iron works started as a bloomery. Peter

Peter,

Thank you very much for educating me and perhaps a few others. http://www.tannehill.org/tsphist.html WOW! 22 tons of iron a day circa 1863. So, logically, they were familiar with the design. We can assume there were other Catalan Furnaces in operation.

Excellent Dr. Drew.

I concur on the direction of the "Damascus Road" going thru North Africa. And as I have posted previously, Bell states that Colonel Grant composed sketches of primitive forges in operation in the interior of Africa. "In this drawing, two natives, each working a pair of single-acting bellows, are seen urging the combustion of a small heap of charcoal situate midway between the two. The ore, in small pieces, is added from time to time, with fresh supplies of fuel; and this is continued until a mass of iron of the required dimensions is obtained." He also notes that Colonel Grant ventures a total yield of "a dozen pounds per day."

'Horse-shoe' would be 'Coarse leaf large scroll asymmetric crolle.'



"economic compound coiling process" is no doubt a trade name for 'machine made' damascus. Not a clue (yet) as to Pointille but the "English Damascus Rosetta Stone" is out there in some little Midlands industrial museum

First, can you attach names or types to the pics posted for Homeless?

Back to Bell - "Manufacture of Iron and Steel"-1884 - Bell describes where the coal, coke & ore veins are located in each country. This post is mostly for France & Belgium. Bell describes furnaces 55 1/4 feet high at the Department of the Meurthe between Pont a Mousson and in the Nancy district. Coke was brought in from the Ruhr - Saarbruck(62 miles), Anzin(277 miles) and Ruhrort(215 miles). At St. Dizier, "an old seat of the French iron trade" a constructed canal allowed the transport of Prussian coke. There were works at Fourchambault and St. Etienne which used ore from La Voulte on the Rhone and Barcelona(Spanish connection?) and were "dependent on that sic(ore) from Mokta in Africa" as well as Elba(Napoleon - able was I ere I saw Elba).

In Belguim in 1882 only 1/6 of the ore used was native at the Liege furnaces. By 1878 the furnaces were totally dependent on ore from Luxemburt for pig iron. Also in 1878, Spanish(mines of Bilbao) and African ores were imported to process for Bessemer iron. So there had to be a long standing relationship between the mines within Spain & some of the African countries. This connection could have been established early on by a transfer in technology, i.e. the "Damascus Road"??

The relationship and knowledge goes back very far. The Viking's had established trade with Byzantium centuries earlier. They were importing wootz for their swords as early as 900 AD. During this time they also controled the Rus. Who later became the Russians. Much of this is documented in:
Blöndal, Sigfús. The Varangians of Byzantium. London: Cambridge. 1978
Ellis-Davidson, Hilda Roderick. The Viking Road to Byzantium. London: George Allen & Unwin. 1976

Look for the armor and sword making centers. Every time you find one, there is evidence of wootz. Many of these centers grow and evolve into making firearms. The perret was a blade making tool that was adopted to make damascus barrels. Daryl and I had chatted about the Viking connection some months back in email. I guess I never posted any of that information here. I will have to dig it up again...

Complicating the topic with armour: as recorded by Philip de Comines and cited in "Engines of War:..." where when the Italian knights were unhorsed and couldn't rise due to the weight of their armour and were chopped-up like cord wood with axes, were
there any suits of Damascus armour, decorative or not?

Raimey,

I have not looked at a lot of armour. It is a complete topic unto itself, so I tread very lightly. We have a couple of collections here in the Chicago area. The pieces I have seen show no resemblance to Wootz. At the same time that fully armoured knights were riding around, gun powder was beginning to come into it's own. The closest I have seen were damascene swords. These have nothing to do with wootz or damascus. It is a term used to describe highly decorated pieces, such as swords.

Remember the whole Crusader myth about the damascus swords that could cut a piece of falling silk. No talk of damascus armour. As for the axes that did the cutting of fallen knights, a good chance they were wootz.

Drew,

I keep coming back to the Fall of Vienna. Here is a good example of why. This miquelet is Albanian / Greek in origin. The lock dates to the late 1600's. The barrel has heavy damascene and the stock is in the Ottoman style. Take a good look at the damascus barrel. It is not Wootz, but pattern welded. They were not able to produce a discernable pattern, but all the elements are there. The only question is the barrel's origin. Who was producing pattern welded damascus this early? It was not coming from Liege or St. Etienne or Eibar. Perhaps Hungary? The silver leaf hides some of the detail.

Drew,
Thanks for the chronological table.
Remember the saying 'What goes round, comes round'?
Well I note that history shows the important role played in iron and steel production by India.
Here are a couple of maybe historic anecdotes.
As a young apprentice engineer in Birmingham I was brought up with such Industrial Giants in and around Birmingham as Guest Keen Nettlefold (GKN)possibly the largest manufacturer of threaded fasteners in the World and Round Oak Steelworks the company famous (infamous?) for producing the barrel for Saddam's Supergun.
Sadly both companies are now gone, Round Oak is now a shopping mall and all of GKN's threaded component manufacturing machines were bought by an Indian and shipped to India to produce fasteners there.
Result is we now buy fasteners from India that shred their threads like helicoils, nuts supplied blank without threads cut, spring washers without spring, etc., because they are cheap.
To me it all harks back to when W.W.Greener complained about Belgian Damascus and forced the Birmingham Proof house to conduct its trials documented in Richard Akehurst's book.
Bring on the Revolution (Industrial of course).

Damascus blade history:
http://damascus.free.fr/f_damas/f_hist/perret.htm


c. 1100 B.C. – Iron was first forged in India
384 B.C. - Aristotle describes the fabrication of sword blades in the Near East and India.
c. 300 B.C. – Crucible steel/Wootz was forged in Southern India.
c. 200 B.C. – Cast iron was forged in China
c. 500 A.D. – Near Nydam, Denmark, a ship sinks with a cargo of pattern welded sword blades. The Vikings (793-1066) used similar blades.
711 A.D. - The Moors (Muslim N. African Berbers and Arabs) gained control over most of Spain until 1212, and were not defeated in Grenada until 1492. Pattern welded sword blades were being produced in Toledo by 1000.
850 A.D. – Abu Yusuf ben Ishaq al-Kindi describes Damascus swords.
c. 1000 – Pattern welded sword blades were also produced in Indonesia (Kris) and c. 1100 in Japan (Tachi).
1077 - Muslim armies capture Jerusalem, leading to the first Crusade in 1096 with the eighth and last in 1270.

Period in which pattern welded sword methodology (folding and hammer forging) was applied to gun barrel methodology (twisting rods composed of thin of layers of iron and steel, wrapping the rods around a mandrel, and hammer welding the edges.)

c. 1200 - Iron musket barrels were first made.
1526 - Ottoman occupation of Hungary until 1686.
1526 Mastro Bartolomeo Beretta (1490 – 1565/68) of Gardone delivers 185 arquebus barrels to the Arsenal of Venice.
1550 – Brescia locks are used throughout the Mediterranean and Middle East.
1557 – Ferlacher Genossenschaft founded.
c. late 1500s – Pattern welded gun barrels were manufactured in India by Ain I Akbari and in Turkey.
1634 – Hungarian gunmaker Caspar Hartmann made Damascus barrels for King Gyorgy Rakoczi I.
c. 1650 - Spain produced pattern welded barrels during the reign of Philip IV 1621-1665.
1683 - The defeat of Kara Mustafa Pasha by Jan III Sobieski at Vienna. Claude Gaier, in Four Centuries of Liege Gunmaking states this was the key date in the development of European damascus as suddenly thousands of pattern welded gun barrels were available for examination.
c. 1700 – Liege is producing Twist barrels.
1718 – Espingarda Perfeyta describes Twist barrel production in Portugal.
1771 - Jean Jacques Perret published L'Art du Coutelier and describes the process of ‘twisting ribbons.’

1798 - William Dupein obtains a British patent for a twist gun barrel of iron and steel.
1798-1799 - Gen. Napoleon Bonaparte's expedition against the Mameluks in Egypt and Ottomans in Syria and modern Israel. Upon his return, Napoleon expanded the production of Damascus barrels in St. Etienne and Liege into the First French Empire period 1804-1814.
1804 – Nicolas Bernard is producing Damascus in Versailles. His son Leopold (1832-1867) and Rene Leclerc were barrel makers in Paris in the early 1800s.
1806 - J. Jones is granted a British patent for a method of making barrels from scelps or strips coiled round a. mandrel so that the edges overlapped, and then welded together the edges of the strip.

Drew,

Well done!

A note to most readers. Some of the dates are approximations. Some are based on single sources. As more research is done, we will cross check sources whenever possible. We should be able to firm-up the dating.

The "Golden Age" circa 1830-1910 is was not included. It will require a little more effort. There are many "sources" for this period. Some of which do agree as to dating. The firmest dates will no doubt come from patent information. We are still looking for Russian, German, Italian, Spanish, etc patents from the Golden Age. The English, French, Belgian and American fronts are pretty well covered.

Also the Ottoman period of influence is still being researched. More than any other sphere of influence, the Ottoman's were response for the diffusion of gunmaking technology. They had established armouries throughout the Persian gulf. In some sweeping moves, they established gunmaking centers in the mediterranean which traded with western Europe. Additionally, they employed many Europeans in Istanbul for the purpose of making weapons.

If you have or know of sources to add to this work, please contribute. We are all learning.

"A Dictionary of Arts, Manufactures and Mines" By Andrew Ure, 1867
http://books.google.com/books?id=sIMDAAAAQAAJ&printsec=frontcover&dq=ure+dictionary

Interesting description of forge welding fluid steel barrels using a rollers and longitutidal seams.

Also, I believe the Clouet referred to here is Jean-Francois Clouet (1751-1801), director of the Daigny Steel Works. Whether that is true or not, the description of working damascus, though for blades is interesting reading.

Quote:
Barrel-welding by Machinery. — The barrels of musquets, birding-guns, &c., or what are called plain, to distinguish them from those denominated stub or twisted barrels, have of late years been formed by means of rolls, a process in which the welding is first effected on a short slab of thick iron, and then the barrel is brought down to its destined length and form, by repeatedly passing it between a pair of rolls, that have been previously grooved to the exact shape of the barrel intended to be made.
......

Clonet and Hachette pointed out the three following processes for producing Damascus blades : 1, that of parallel fillets; 2, that by torsion; 3, the mosaic. The first, which is still pursued by some French cutlers, consists in scooping out with a graving tool the faces of a piece of stuff composed of thin plates of different kinds of steel. These hollows are by a subsequent operation filled up, and brought to a level with the external faces, upon which they subsequently form tress-like figures. 2. The method of torsion, which is more generally employed at present, consists in forming a bundle of rods or slips of steel, which are welded together into a well-wrought bar, twisted several times round its axis. It is repeatedly forged, and twisted alternately ; after which it is slit in the line of its axis, and the two halves are welded with their ontsides in contact ; by which means their faces will exhibit very various configuration 3. The mosaic method consists in preparing a bar, as by the torsion plan, and cutting this bar into short pieces of nearly equal length, with which a faggot is formed and welded together ; taking care to preserve the sections of each piece at the surface of the blade. In this way, all the variety of the design is displayed, corresponding to each fragment of the cut bar.

The blades of Clouet, independently of their excellent quality, their flexibility, and extreme elasticity, have this advantage over the oriental blades, that they exhibit in tho very substance of the metal, designs, letters, inscriptions, and, generally speaking, all kinds of figures which had been delineated beforehand.

Notwithstanding these successful results of Clouet, it was pretty clear that the watered designs of the true Damascus scymitar were essentially different. M. Urcant has attempted a solution of this problem. He supposes that the substance of the oriental blades is a cast steel more highly charged with carbon than our European steel, and in which, by means of a cooling suitably conducted, a crystallisation takes place of two distinct combinations of carbon and iron. This separation is, he thinks, the essential condition ; for if the melted steel be suddenly cooled in a small crucible or ingot, there is no damascene appearance. If an excess of carbon be mixed with iron, the whole of the metal will be converted into steel ; and the residuary carbon will combine in anew proportion with a poriion o' the steel so formed. There will be two distinct compounds; namely, pure steel, and earburetted steel or cast-iron. These at first being imperfectly mixed, will tend to separate if while still fluid they be left in a state of repose ; and form a crystallisation in which the particles of the two compounds will place themselves in the crucible in an order determined by their affinity and density conjoined. If a blade forged out of steel so prepared be immersed iu acidulous water, it will display a very distinct Damascus appearance -, the portions of pure steel becoming black, and those of carburet ted steel remaining white, because the acids with difficulty disengage its carbon. The slower such a compound is cooled, the larger the Damascus veins will be. Tavemier relates that the steel crucible ingots, like those of wootz, for making the true oriental Damascus, come from Golconda, that they are the size of a halfpenny roll, and when cut in two, form two swords.

Steel combined with manganese displays the Damascus appearance very strongly.

A mixture of 100 parts of soft iron, and 2 of lamp black, melts as readily as ordinary steel. Several of the best blades which M. Bréant presented to the Société d'Encouragement are the product of this combination. This is an easy way of making cast-steel without previous cementation of the iron. 100 parts of filings of very grey cast-iron, and 100 parts of like filings previously oxidised, produced, by their fusion together, a beautiful damascene steel, fit for forging into white arms, sabres, swords, etc. This compound is remarkable for its elasticity, an essential quality, not possessed by the old Indian steel. The greater the proportion of the oxidised cast-iron the tougher is the steel. Care should be taken to stir the materials during their fusion, before it is allowed to ei:ol; otherwise they will not afford a homogeneous damasc. If the steel contains much carbon it is difficult to forge, and cannot be drawn out excipt within a narrow range of temperature. When heated to a red-white it crumbles under the hammer ; at a cherry-red it becomes hard and brittle ; and as it progressively cools it becomes still more unmalleablc. It resembles completely Indian steel, which European blacksmiths cannot forge, because they are ignorant of the suitable temperature for working it. M. lireant, by studying this point, succeeded in forging fine blades.

Experience has proved that the orbicular veins, called by the workmen knots or Oicrns (ronces), which are seen upon the finest Eastern scymitars, are the result of the manner of forging them, as well as the method of twisting the Damascus bars. If these be drawn in length, the veins will be longitudinal ; if they be spread equally in all directions, the stuff will have a crystalline aspect ; if they be made wavy in the two directions, undulated veins will be produced like those in the oriental Damascus.

PeteM:

As usual, excellent and informative posts. The pics are very similar to what I have seen near ore mines in reading other texts, that is until coke was discovered, or it's use in making steel as noted by the pioneer Dud Dudley in 1618 in "Metallum Martis". He had trouble from the get-go and about 50 years later Abraham Darby resurrected it. Before then, many of the furnaces were in the entrance or very near the mine. So, if one retraces the history of the mine, the direction of the transfer of technogoly may be discovered. Also, you can really see the impacts or effects of machines based on hydraulics which also worked the hammers.

British barrels that were labeled laminated steel were, by law, required to have a minimum of 60 % steel in the composite. High quality British laminated steel barrels did NOT look like twist barrels or have a twist pattern.. If you read Greener carefully, you will find that the barrels that came out on top in the 1888 trials were three blade (or iron) laminated steel----not twist. If you further read Greener on this subject, he describes the three blade laminated steel barrels as similar to three blade Damascus but assembled in a slightly different manner such that a herringbone pattern was produced on the barrels. They were probably assembled with the twisted ropes forming the ribands all having the same twist direction whereas normal crolle Damascus is made with the ropes having alternating twist directions. John Brindle's multi-part article on Damascus barrels in early issues of the DGJ also addresses the increased strength of Damascus compared to plain twist for welded pattern barrels.


And I remain confused
  • A 4 iron damascus barrel would have 4 Baguettes?
  • A twist barrel would not go NOT through the tordu (twisted) step?
  • A laminated barrel was a damascus with the twist arranged differently?

1. Four iron crolle starts with four 'irons,' 'stripes,' 'bands,' 'rods,' 'ribbons,' 'baguettes, or 'blades' and is made up of some combination of alternating layers of iron and steel.
2. The 'iron' used for a Twist barrel had no more than 50:50 iron/steel and was not twisted prior to being 'twisted' (wrapped) aroung the mandrel
From the Journal of The Federation of Insurance Institutes of Great Britain and Ireland, 1904 "Gun and Small-Arms Factories" by A.E. Patrick, p. 149-175 From 'Gun Barrels' starting on p. 159
"Plain twist or scelp barrels are made from plain straight rods or ribands. It is the twist in the rods that cause the figure to appear in the barrels and all iron so twisted is called "Damascus"...
3. There are several descriptions of Laminated steel at the beginning of the 'British Laminated Steel' album
http://www.picturetrail.com/gallery/view?p=999&gid=18063717
Short version for my pea brain: Twist and Laminated steel both start with the mixture of iron and steel fused together in a 'bloom' which is then rolled/hammered into rods. The rods for damascus are NOT fused together but are individual strips of iron and individual strips of steel. Laminated steel rods are twisted much less than damascus, but may still have a 'crolle' pattern and are then called 'Laminated Damascus' And laminated steel has a much higher ratio of steel to iron-usually 3-4:1


They may also have a linear pattern, but it is much less complex than 'Herring-bone' damascus.


Laminated usually has a very random black/white - iron/steel variegated pattern


The best description of the production of Twist, Damascus, and Laminated steel I've found follows:

Engines Of War: or, Historical and Experimental Observations on Ancient And Modern Warlike Machines And Implements, Including the Manufacture of Guns, Gunpowder, and Swords with remarks on Bronze, Iron, Steel, &c. Henry Wilkinson, M.R.A.S. London 1841
p. 70 Part III 'On The Manufacture of Fire-Arms, And Modern Improvements'
http://books.google.com/books?id=0XJeF_o...w3u60I#PPA70,M1

Starting on p. 87 Forging of Gun-Barrels A description of Stub, Stub-Twist, Wire-Twist, Damascus-twist, Stub-Damascus, Charcoal iron, Threepenny skelp iron, Two penny or Wednesbury skelp, and Sham-damn skelp.
The most approved modern method of converting…(horse-shoe nails)…into (Stub-Twist) gun-barrels after carefully sorting and picking the, to see that no cast-iron or impurities are mixed with them, is first to put about half a hundred weight into a large cast-iron drum or cylinder, crossed internally with iron bars, through the centre of which a shaft passes, which is connected by a strap with a steam-engine, and the revolution of the drum actually polishes the nails by their friction against each other; they are then sifted, by which every particle of dust is removed. The steel intended to be mixed with them is clipped by means of large shears, worked by the engine into small pieces, corresponding in size to the stubs, and afterwards cleansed by a similar process. About 40 lbs. are thrown on to the inclined hearth of an air-furnace, where they are puddled or mixed together with a long iron rod, and withdrawn in a mass called a bloom, almost in a state of fusion, to be welded under hammer of three tons weight, by which it is formed into a long square block: this being put in, at another door of the same air-furnace, is raised to a bright red heat, and drawn out under a tilt hammer of a ton and half weight, into bars of proper size to pass the rollers, by means of which it is reduced to rods of the required size.
p. 95 Possibly a description of what was later termed Laminated Steel
For the finest description of (Stub-Twist) barrels, a certain proportion of scrap steel, such as broken coach-springs, is cut into pieces and mixed with the iron by the operation called puddling, by which the steel loses a considerable portion of its carbon, and becomes converted to mild steel, uniting readily with the iron, and greatly increasing the variegation and beauty of the twist. In whatever manner the iron may be prepared, the operation of drawing it out into ribands for twisting is the same. This is effected by passing the bars, while red hot, between rollers until extended several yards in length, about half an inch wide, and varying in thickness according to whichever part of the barrel it may be intended to form: these ribands are cut into convenient lengths, each being sufficient to form one-third of a barrel: one of these pieces is made red hot and twisted into a spiral form, by placing on end in the prong of an iron rod, which passes through a frame, and is turned by a handle, the riband being prevented from going round without twisting by means of an iron bar placed parallel to the revolving rod. The spiral thus formed is raised to a welding heat, and dropped on to a cylindrical rod, which being struck forcibly on the ground (called jumping) the edges of the spiral unite, and the welding is then completed by hammering on the anvil. The other spirals are added according to the length of the barrel, and the forging is finished by hammering regularly all over. The ends of the spirals should be turned up and united at each junction of spirals, to avoid the confusion in the twist occasioned by merely dropping one spiral on anther; but this is rarely done. Wire-Twist, of any degree of fineness, may be obtained by welding alternate laminae of iron and steel, or iron of two qualities, together; the compound bar thus formed is drawn into ribands, and twisted in the same manner as the preceding.
p. 96 The iron called Damascus, from it’s resemblance to the celebrated Oriental barrels and swordblades, is now manufactured in great perfection in this country, as well as in France and Germany, and may be varied in fineness or pattern to almost any extent, according to the various manipulations it may undergo. One method is to unite, by welding 25 bars of iron and mild steel alternately, each about 2 feet long, 2 inches wide, and ¼ of an inch thick; and having drawn the whole mass into a long bar, or rod, 3/8 of an inch square, it is then cut into proper lengths of from five to six feet; one of these pieces being made red hot is held firmly in a vice, or in a square hole, to prevent it from turning, while the other end is twisted by a brace, or by machinery, taking care that the turns are regular, and holding those parts which turn closer than others with a pair of tongs, the rod is by this means shortened to half it’s original length, and made quite round. If only two pieces are employed to form the riband, one is turned to the right, and the other to the left; these being laid parallel to each other are united by welding and then flattened; but if three square rods are used, the centre one is turned in a contrary direction to the outside ones, and this produces the handsomest figure. By these operations the alterations of iron and steel change places at every half revolution of the square rod composed of twenty-five laminae; the external layers winding round the interior ones, thus forming when flattened into a riband, irregular concentric ovals or circles. The fineness of the Damascus depends on the number and thickness of alterations; but when wound into spiral form, and united on its edges by jumping, the edges bend round and the figure is completed.

On the recomendation of CC/dt, I was able to get on inter-library loan Purdey Gun & Rifle Makers, The Definitive History by Donald Dallas. This work is a comprehensive history of the company, the family,and the men that made the guns, as much as the guns themselves, and there was very little discussion of the barrels, and no mention of any specific named pattern nor, after the mid-1820s, if any barrels were out-sourced. I was able to establish the progression of barrels used from the excellent pictures. In summary: prior to the 1840s all brls were twist. In the 1840s-1860s Laminated steel and large scroll asymmtric 2- and 3- Iron Damascus appear



About 1870, a distinctly finer small scroll symmetric 3- and 4- iron pattern appears, very similar to the 'Finest' damascus used on D grade Parkers



c. 1890, most of the brls were Whitworth steel

Here are the details:

p.15
Purdey began producing his own barrels in the mid-1820s.
Prior to that time, most were obtained from Charles Lancaster (‘CL’ marked) or William Fullerd (‘WF’ marked)
p. 27
Barrels made by Purdey were stamped ‘JP’ after 1826
Also Thomas Evans ‘TE’ and Thomas Parkin ‘TP’ in mid-1820s.
No further mention of any out-sourced barrels thereafter.

1818 – 16b Flintlock #14 - twist
1821 – 14b Dbl percussion shotgun #287 – twist
1844 – 16b Dbl percussion rifle #3845 - Laminated
1863 – 12b Dbl Bastin/Purdey slide action pinfire #6424 – Damascus ?2 rod
1864 – First pattern thumb-hole pin-fire #6829 - ?Laminated Damascus
1866 – 12b Dbl First pattern thumb-hole #7225 – Laminated steel
1867 – 40 cal. Dbl Express rifle #7464 – Large scroll 2 Iron Damascus
1868 – 12b Second pattern thumb-hole #7745 – Large scroll 3 Iron Damascus
1869 – 12b muzzle-loading shotgun #7902 – Large scroll 3 Iron Damascus
1872 – 10b bar-in-wood hammer gun #8623 – First appearance of Fine small scroll annular 4 Iron Damascus
1873 – 12b bar-in-wood hammer guns pair #8998&9000 – same Damascus.
c. late 1870s – Introduction of Quality A – E
Jan. 1, 1880 - Pair #10614/10615 were delivered to Mr Hunt by James Purdey 'The Younger' with The "New Whitworth Fluid Pressed Steel".
1881 – Bar-in-wood hammer gun #11090 – same Damascus.
1885 Catalog - Quality A- Best Gun “The barrels of best Guns can if desired be made of Sir Joseph Whitworth & Co.s fluid pressed steel at an extra cost...
Quality B- “fine Damascus barrels.” No other mention of barrel material.
Crolle pattern illustrated is same small scroll, symmetric, annular, 4 Iron.
1884 – Beesley gun #11837 – same scroll pattern but 3 Iron
1886 – 8b hammer rifle #12371 – same scroll pattern but 3 Iron
c. 1890s – Guns illustrated had Whitworth steel.

Sure wish we knew if Purdey made that "Finest" Damascus after about 1870. The book states that Aston Snr. began with Purdey's in the 1850s, and his son, Harry, was also a barrel maker until 1930.

Raimey,

Most of it was being done in the rolling mills, for the fabrication and initial welding of the billet. I know there were machines for twisting the iron, but do not know if the rolling mill or the barrel maker was doing it.

The final steps of wrapping it around a mandrel, could have been done by machine, but I have found no proof of that yet.

I believe that by 1870 the mills were producing the forged billets and the twisting was mechanized in both England and Belgium. I have some patent numbers that I have tried to search for, but can not seem to get results with the Beglian patent database. It does not appear to go back that far even when I provide the patent number, applicant description and holder's name.

Pete,
Somewhere in my collection of files from others on this bbs, I had a picture of a machine that wound the ribbon of damscus on a mandrel.

I know there is a lot of opinion that all damascus was hand forged, but some of the later damascus has such a consistant spiral wrap and straight line of the forgeweld of the composite ribbon that I really think striking the material with a hammer would leave the forgeweld line with irregularities very visible.

Pete M-reference your post a few pages back about Siyaqat: It is a form of Arabic calligraphy. The Ottomans (Osmanli) were Turks, not Arabs. Some of the people that they conquered and subjugated were Arabs, and they did use some Arabic words, but most court and palace records and communications were conducted in Persian, using Arabic script such as Siyaqat for the chancery. For the uninformed or uninitiated, we use Arabic numerals for our mathematics, but the system or "language" is base 10.

If you have more detailed information about the records located in Istanbul, pleased advise and I will do what I can to research this at the local level.

The end of the damascus trade.

The technology to build damascus was mothered by the necessity to produce light barrels capable of handling the longitudinal and axial stress of gun powder ignition. This was in an age when it was common to produce a barrel by bending a flat piece of iron around a mandrel and welding it along it's entire length. The combination of iron and steel in tandem with the spiral wrapping produced a significantly stronger and safer firearm.

The reasons the trade ended are multi-faceted. While the destruction of the rolling mills, barrel production centers and decimated work force inflicted by WWI are primary, the trade would have ended eventually.

The change was rooted deep within the fabric of western Europe.

The industrial revolution progressed. Metallurgical developments produced stronger steels. Railroads were built. As the technology to produce stronger steels rose, so too did unionism and the shattering of the guild system.

For many decades, the owners had ruled like barons over their workers. They saw no reason to support state sponsored programs such as schools, health care and the like. They found the federal government intrusive and preferred to cling to their own regional ethnicity's. For a time this view was shared by the labor force. Eventually, as the owners increasing used machines, the workers where displaced. The guild could provide the training needed to learn a trade. The small cottage worker found themselves living in more urban setting with decreasing ability to control their own work habits.

As early as 1849 the S.S.M.O.A.L. or Société de Secours mutuels des Ouvriers Armuriers Liège ( Mutual Aid Society of Liege Arms Workers ) was formed. This early mutual aid society was largely geared to helping workers with things like housing, food, etc.

In 1886 the town of Liege called a meeting of the owners. They had a proposal for them. An establishment of a school to train workers. They suggested that the town would help fund such a school. They would seek funding from the federal government. In addition, they wanted the owners support. The owners drafted a response. They saw no need to educate their labor force. After all, the guild system provided all the education that was required.

One of the 1st truly modern firearms makers in Belgium was Fabrique National. FN was originally founded by a group of owners / investors, Henri Pieper being one, in 1889. It was based on the most modern technology. Large tracts of land were acquired. Huge factories rose, building after building. Labor was needed. There was a rush to the doors as people sought work. FN was looking at a new economy of firearms production. Before a gunmaker-owner simply set a rate for which he purchased parts. He could even pay cottage workers to do the final assembly. Guns per hour, became a new phrase on the owners lips. The work force suffered and finally walked out on strike in 1895. Strikes were not unheard of in Belgium, but were a rare thing for the arms industry. At this time the U.F.A Union des Fabricants d'Armes U.F.A ( Union of Arms Workers ) approached the officials of Liege. They lent their support and the L'école d'Armurerie de Liège ( School of Liege Gun makers ) was founded in 1897.

A sense of national pride was growing in Belgium. With the advent of the railroad, relatively rare and exotic commodities were becoming common place. Oranges, lemons, spices, clothing were now available. People had the bicycle as a means of transport. Things were looking up. The only problem was money. To purchase all this took cash. The owners were staunch. They had paid your father 2 francs per barrel, what made you think your barrels were worth 3 francs? Things came to a head in 1908. The barrel makers guild found themselves locked out. The people of Nessonvaux and Liege opened their hearts and their doors. They took in the children of the barrel makers guild and provided them with food and shelter.

One of the voices of change was Léon Troclet. He supported the workers cause. He called for even more schooling. Léon Troclet was one of the founders of the Belgium Labor Party and of the F.G.T.B. , La Fédération générale du travail de Belgique ( The General Federation of Belgian Labour ), one the largest unions in Belgium.

The strikes continued unfortunately. In 1912, Lochet factory was embroiled in a strike.

It's here, it's here
Our local library was able to get a photocopy through the ASU library of The Metropolitan Museum of Art, Vol. 16, No. 9, May 1958. An article was written by Stephen Grancsay, Curator of Arms and Armor "The new Galleries of Oriental Arms and Armor"
A new exhibit was opened to showcase the museum's extensive collection of arms and armor from India, Persia, Turkey, Japan, and Indonesia. Most of the article was devoted to swords and armor, and a c. 1600s Turkish shield was picture with a damascened pattern similar to 'Stars and Stripes' damascus.
from p. 249
The usual designation of a blade of watered (Wootz) steel is 'Damascus blade,' a name merely derived from a trading post of the caravans of East and West. It is well known, however, that the metal for the noted Damascus blades of medieval times was not made at Damascus but at Kona Samundrum near Nirma in Haiderabad. The finest blades seem to have been always made in Persia, often from imported Indian steel. Of all the signatures of oriental bladesmiths the most famous is that of Asadullah of Ispahan, the bladesmith of Shah Abbas the Great (1587-1628)...

Indonesian 'Kris' and Japanese blades are also discussed.

Little is said regarding the firearms in the collection BUT this is on p. 248
Their laminated steel-twist barrels were brought to a high state of perfection. It was after Napoleon's expedition to Egypt that Damascus barrels were sent to Europe and achieved so high a reputation that the method of making them was copied. In this process bars of iron and steel were placed in regular alterations and welded into one bar; then this bar, or several of them placed together, was twisted spirally and the whole welded. The patterns, like those on blade of watered steel, are intricate and ofter elegant.

A c. 1600s Turkish miquelet is shown with easily identifiable but crude Two Iron Crolle, and NOT twist.

Not alot of answers, but at least we know Two Iron Crolle barrels were being used by the Turks in the 1600s.

Great stuff. Circa 1600's pattern welded is truly very early stuff. Do they give a catalog number for the miquelet?

Quote:
Damascus Steel.—According to Demmin,* the treatment of steel known as "damaskeening" is no longer practised at Damascus. The metal used is a cast steel, in which-a strongly marked figuration is produced by the presence of crystallised graphite, which is rendered evident by the corrosive action of acids. In 1804 Clouth imitated the oriental Damascus steel, and Stodart and Faraday considerably improved the process of manufacture. At the present time artificial polished Damascus steel is largely made in France, whence it is exported to the East. It is also made for gun barrels at Liege, and for swords at Solingen and Passau. There are black, brown, and yellow damaskeenings, which are produced in the following manner :—Several bars of steel of different hardness, or of iron, cast steel, and steel, are welded together, hardened, and formed into sword blades. They are then treated with acids, where by the harder portions acquire a dark colour, whilst the softer portions remain bright.

The figurations appear wavy, striped, or mosaic-like, according to the manner in which the various bars were hammered together. The finest and most expensive variety is said to be the Liege Eenard damaskeening, which is formed of three bars welded together, each of which consists of seventy-two iron and seventy-two steel wires. The gun barrel is formed by smithing this compound bar, which is wound round an iron cylinder placed over a mandril. When finished, the iron cylinder is drilled out.

An imitation of damaskeening, which is used in Liege for cheap
sporting guns, is produced by affixing paper printed in lithographic ink on the surface of the finished iron or steel gun barrel, and into this dilute sulphuric acid is poured, which corrodes the portions of the barrel not protected by the ink on the paper. Ou heating the gun barrel, blue and brown colorations are produced

"A Description of Indian and Oriental Armour"
By Wilbraham Egerton Egerton, 1896

This is the most complete description of forge welded damascus barrels being done outside of Europe.
Quote:
It is said that the Persians distinguish by ten different names the varieties
of watering. One of the most prized and rare is that which takes its name
from the grains of yellow sand. There are, however, four main patterns
generally recognised :—
1. " Kirk narduban," meaning the forty steps or rungs of the laduer, in
allusion to the transverse markings of fine grey or black watering. The idea
is also expressed in an inscription on one of the blades, that the undulations
of the steel resemble a net across running water.

2. " Qará khorásán," nearly black, with fine undulations proceeding like
water either from the point to the hilt, or the reverse way.

3. Qará Tábán, " brilliant black," with larger watering and more grey in
tone.

4. Sham, or simple Damascus, including all other varieties.1
On the introduction of the use of firearms, the methodss long and perhaps
exclusively known to the Asiatics, of manufacturing sword-blades of peculiar
excellence, was transferred with' some modification to that of gun-barrels, and
are still in use.2

In Persia, Kabul, the Punjab, and Hind the same general principles prevail,
but the matchlocks of the last are held deservedly in the highest estimation.

In some parts of India the workmen prefer for the material of their barrels
the iron of old sugar boilers, but they use in Kashmir the iron of Bajaur (in
the country of the Yusufzai) as it comes from the smelting furnace, after
receiving a few blows whilst hot, which condense it into a rude kind of pig, the
weight of which varies from five to eight seers (10 to 16 Ibs.), and which sells
as high as 4d. a pound. The first process consists in cutting the pig when
heated into narrow strips witli a cold chisel, and in this operation the iron
loses one-fourth of its gross weight. Each of these strips separately is
brought to welding heat, and worked smartly under the hammers of two men
on a block of limestone as an anvil. When the slag is expelled, each strip is
drawn out by the hammer into a strap about 2 feet long and 11/5 inch broad,
and 1/5th inch thick. One of these straps has its ends so brought together as
to enable it to include about 20 other short straps cut up for the purpose,
some being placed on their edge, and others wedged in between the lengths,
во as to form a compact mass. It is then put into the fire and lightly heated,
receiving a few blows upon both faces as well as upon the edges.

It is next smeared over with a paste of clay and water, and when dried it
is exposed first to a light welding heat, and after a slight hammering to a
stronger heat, when it is vigorously and quickly beaten into four-sided bars
1 Cat. Mus. Zarkoe-Seloe,
p. 242. In addition to those, Sir Л. Burnes mentions " Akbaree,"
in which the pattern ran like a skein of silk the whole length of the Made, and " Beguraee,"
where it waved like a watered silk. '-
Moorcroft's Travels, p. 195. 1841.

about a foot long, and a finger's thickness. These are again heated, separated,
and drawn out into square rods about J-inch broad on each face. These are
then twisted from right to left, while the part which is to be twisted is heated
to a red heat nearly verging upon white. This process is repeated by heating
two or three inches at a time, and then cooling it with cold water, till the
whole rod is converted into a fine screw, which is made as even as possible.

To make an Iran barrel six or eight rods are required. When eight are
employed, four of them have the twist from right to left, and four from left
to right. Every rod after having been slightly heated is lightly hammered
on its two opposite sides equally, so that two sides have the threads beaten
down, and the two others have the threads standing, and retaining their
original roundness. Each rod is now made up of lengths of the same
direction of twist, and is laid parallel to the other, so that rods of opposite
twist are in alternate succession.1

The steel having been formed into bars is now ready for manufacture into
gun-barrels.2

The extremities of the bars are welded together, and the baud or skelp is
now ready for being formed into a hollow cylinder through being twisted
in a spiral line upon itself, which is begun at the breech or thicker end, and
continued to the muzzle. When the twisting is so far completed that the
edges of all the twists stand even, and the cylinder is nearly equal, it is coated
with a thin paste of clay and water, and is then ready for being welded.

A welding heat is first taken in the middle of the cylinder, and the edges
of the twists are brought together by the breech being struck down upon the
stone anvil perpendicularly for the purpose of jumping up the edges. The
welding is constantly repeated, so that the twist, which was jumped up, is
successively hammered when the heat is well on, till the barrel has been
welded up to the muzzle.

This process is then repeated, commencing from the middle to the breech,
and afterwards from the middle to the muzzle, during which an iron rod is
introduced at each end and tised as a mandril. A third heat nearly red is
now taken at the whole surface of the barrel, which is then made regular and
level by smartly hammering it. The barrel is then fixed horizontally through
a hole in an upright post and bored, after which its surface is filed, polished,
and prepared for bringing out the damasked lines. " Jauhar " is brought
out through biting the whole surface with " kasis," a sulphate of iron.

The barrel is completely freed from grease or oil by being well rubbed with
dry ashes and a clean rag. About three drachms of sulphate of iron in powder
is mixed with as much water as is sufficient to bring it to the consistence of
thick paste which is smeared equally over the whole surface of the barrel, the
nmzzle and breech being at the same time carefully plugged. About two
hours afterwards, when the metal has assumed a blackish colour, the coating
is rubbed oft', and the barrel cleaned as before.
1 Barrels
arc called " pechdár " when plain or simply twisted, "jnulmrdár " tvheu dunmsked.
For the latter the rods are disposed according to the kind of brilliant or damasked lines to be
produced, called either from the country as " Iran " or Persian, or from the figure, as " pigeon's
eye," " lover's knot," " chain," &c.
s Cf. Joiirn. Asiatic Soc. 1841,
p. 83.; Mooreroft, II., 195, 213,

The barrel is then smeared with a preparation composed of the same
quantity of sulphate of iron and four ounces of water, and is hung up in the
well.

Every gunsmith has, in the floor of his shop, a well about two yards deep,
the bottom of which is covered with a layer of fresh horse-dung half a yard
thick. Suspended by a string from the cross stick at the mouth of the well,
the barrel which has been covered with the mixture as before is taken out
every morning and cleaned with dry ashes and cloth, and hung up for 24
hours with a coating of the solution. This process is continued for 20 days
or a month till prominent lines are formed on the surface of the barrel,
separated from each other more or less by other depressed lines or grooves ;
the former will be found to have the same direction as that of the thread of
the screw in the twisted rods. The prominent lines when rubbed are bright
and of a colour somewhat approaching silver, while the depressed lines are
dark and form the pattern.

The " zanjir " or chain damask consists in the introduction of a band of
prominent and brilliant lines disposed like the links of a chain between
parallel plain lines of damask. The processes are the same as before described
in cutting up the " pig," and in reducing the strips into straps, but the " pie "
or " ghilaf " contains only eight lengths, which when welded is drawn out into
straps 1/2 inch broad and 1/8 inch thick. One of these straps being heated is
bent backwards and forwards upon itself in eight continued loops, each an
inch long, and is then worked up into straps 1/3 inch broad, and 1/16 inch thick.
Three of this kind of strap are required in this pattern, one for the chain and
two for the lines. The face of the iron anvil has a perpendicular hollow
about one-quarter of an inch deep, and about one-third of an inch across.
One end of the strap is laid while cold across this groove, and driven down
into it by a small chisel and hammer, by which the strap receives a bend or
angle. Its opposite face is then placed across the die near the acute elbow
made by the chisel, and is in like manner wedged into it, after which the
operation is reversed until the whole band is converted into a frill of loops.
This frill is then heated, and the operator holding one end with a small pair of
tongs brings two pairs of loops together leaving the ends open. This is
continued till the frill is much reduced in length through the loops of the
strap standing at right angles to its general direction. Different lengths of
frill are welded together, so as to form a ribbon six spans long, placed in
contact with two plain straps set on edge, and four rods, two on each side
twisting alternately, from left to right, and the reverse. The general band of
these seven straps is then treated as that for the " Irani " damask.

The chain damask is in general preferred to all other varieties, excepting
the silver twist. The Kashmiris still make blades for daggers in the same
way, as one which was made for the author at Srinagar to fit an Indian
jade handle is damasked, and Moorcroft relates that they made sword blades
for him to order, though they did not usually manufacture them. It is said
that " jauhar " is imitated in Hindostán by lines being traced in a coating
of wax laid over the metal, and the barrel being exposed to the action of
sulphate of iron.

Looks like Desire Mineur, of Prayon, Liege, had quite the chutzpah trying to claim exclusive rights to "Chain-pattern" damascus in 1904

Well you have to hand it to revdocdrew. I just got a copy of Heuse-Limoine, "Manufacture of Damascus Gun-Barrels" circa 1894. He states on page 4;

Quote:
The Barrels thus manufactured with good charcoal iron proved to be already a great progress with respect to solidity, but offered of the Damascus appearance which was visible by certain traces of the spiral produced by the appearance of the fibres or the varnish of the metal....

....almost like the designs on our hanging papers in our rooms, with the only difference, that in these the variety is produced by the colours on the surface, whilst the figures on the Damascus are produced by the substance or material like the designs or patterns in our linnen-weavers.

So, we have a major Damascus barrel maker of the period who sees the patterns of his barrels in wall paper and linen. Which leads full circle. The Victoria and Albert museum has examples of Walloon Turkish rugs...

Charles A. Herzog Sr. gave me some great pics of guns and his damascus production salesman's sample rod, so I made another album demonstrating the Parker hammerless damascus grades and the sample rod

I have a Double barrel shotgun with hammers. The apparatus that the hammers hit have been taken out. A gun dealer here in Spokane, WA says that is not a big deal. He was impressed with the shape the gun was in. It has a beautiful walnut stock and beautiful engraving on the metal. On the side it has Clark and Sneider engraved and on the bottom CE Sneider. One gun dealer could not find any proof marks and figures it was made in the US. He did not know anything about the shotgun but did say there was a CE Sneider that made hand guns. Do you have any information. The Shotgun was given to my father as a gift by some friends whose family came from the East Coast. It was his friends grandfathers gun and their family was wealthy which would make me guess that it was a very good gun made by a good gunmaker when their family acquired it. Any information you might be able to provide would be welcome. All of the people who would know about the shotgun have passed away.

Thanks for any help you can give me.
