[QUOTE="shortgrass, post: 1023260, member: 24284"] Brownells (and maybe Midway) markets a formula for barrel browning made by Mark Lee. The depth of color can be varied by the amount and number of applications. Requires no fuming or boiling water tank, just the appropiate degreasers and a clean carding brush. Those yellow colors on the shotgun side plates, probably reminants of case colors. I've work with the original CCH charcoal process for over 20 years. A heat treat oven is required,,, a kiln would be real iffy as most kilns are top loading. You have to be able to remove the crucible and get it to a quench tank. Top loading kilns make that awful hard. Remember, you're dealing with temps above 1333 deg. F. That's hot enough that a minor slip will be disasterous! Aquiring old forumlas is like finding buried treasure, trouble is the stuff needed may be near impossible if not completely impossible to obtain. Charred leather was used in the past for CCH. Won't work now as the tanning process now uses chromium and that'll contaminate the works. Same situation found with browning & bluing formulas.
