Sorry Dtm but ed has an agenda, and we've endured it since about 2006. He of late has been having trouble recalling our discussions so this might help

Heating any shotgun receiver without controlling the temperature and heat duration is very dangerous and can damage guns and potentially harm shooters. in additional, if the receiver is heated to very high temperature, such as that required for the bone charcoal process to be effective, then the structure of the metal has been changed and should be tempered back to provide some elasticity. otherwise, the receiver is as brittle as glass and may crack or shatter upon firing of the gun. in my opinion, a low, controlled heat process, combined with specific chemicals is the safest way to recolor a shotgun receiver. so long as the heat is kept low and controlled the metallurgy is not changed and no harm is done to the gun nor is there any potential for danger to the shooter, due to incorrect heat treating, which is the inherent flaw in the use of the high heat bone charcoal process when applied to shotgun receivers.
this is exactly the potential disaster that can result in the use of the high heat, bone charcoal process to recolor a shotgun receiver. the gun becomes a potential bomb, without proper tempering of the metal after the coloring process is completed. the high heat bone charcoal process may work fine for some winchester rifle receivers, but it should never, never be used on a shotgun receiver.
i utilize the services of Ed Lander, for most of my repair and enhancement needs. Old Ed has over 60 years of experience in the gunsmithing trade and does fine work at fair prices. He has recolored literally hundreds if not thousands of shotguns receivers using his low controlled heat, chemical process. my criticism of those who case color shotgun receivers via the high heat bone charcoal method is well known, particularly by those who practice that black art as a business.
i do not know much more about old ed's case coloring process. he has developed his techniques over many years of trial and error. he even has different chemical formulas that simulate different factory colors for different guns, depending on when they were made. i believe he may use a potters kiln to precisely control heat. what i do know, is that his top priorities in all of his work are shooter safety and customer satisfaction.


He will now play the victim, simply seeking the truth, while cowardly hiding behind internet anonymity.
