Any of you metal artists have formulas for blackening brass and nickel silver? Want to file work it, darken it and then polish the highlights.

Brass black from birchwood casey works real well and is not very expensive.

I'll try that. Ever tried it on nickel silver?

I will give it a try right now and let you know.

It worked on a piece of clean nickle silver wire within 30 seconds. Followed by cold water rinse then wiped. Deep blue / black.

Man that was fast. I appreciate it. Might even post a pic if I get this knife done the way I want it to look. Thanks again snakewood3
