After my first rust as per all instructions, I boiled my barrels. Instead of a black finish I get a red. What's wrong? Thanks. Ed

I Would suspect contaminated boiling water,suggest clean and polish again, re-rust and then boil in de-ionised water also called de-mineralised water from a supplier like Culligan dealer.

What rusting solution did you use , how many coats and did you
use logwood and ferrous sulfate in the water?

I think Dubbletrubble hit it. My heat source does not get the boil rolling. Only a simmer. I used diluted Laurel Mountain 1:1. The rusting was perfect. Boil not so much. Thanks everyone for their help. Should I strip the barrels and start over?

In Angier's book on Blueing & Browning, page 18, he mentions that any carbonate in the boiling bath will 'partly or entirely convert the carefully formed black oxide into fox-red carbonate: a most unwelcome accident that is hard to repair even with a coarse scratch brush.'
I suggest that your boiling water had become corrupted with carbonate (hard water?) and this caused your problem rather than any problem with the temp of the bath.
When blacking barrels, I rarely bother to push the tank temperature to a full rolling boil, I find that the black oxide forms very happily at anything over 92 degrees. Having the tank right up to temp doesn't even seem to speed the process.
I must admit to no experience with blacking Damascus and if this was what you were doing, there may be a different issue.

Toby: I had not thought of the water's PH. I use well water, next time I'll try distilled.

This is 5 rustings and 2 etchings on a 1899 L.C. Smith F grade Hammer gun with Stub Twist barrels. Humidity 88% in box, tray of warm water to accelerate rusting. Left from 4 hrs-12 hours (overnight). Laurel Mountain Forge Browner, first coat full, then dipped swab in water and then into LMF. Boiled for 5 minutes in distilled water, last 2 rustings, etched with Radio Shack 15% echant in about 85% distilled water for 5 seconds. Final, heated barrels warm to touch and coated with boiled linseed oil and let sit until hard.
