Industrial Chemicals .

Ive always used Phillips gun blue and have even blackened brass with it. Never liked the Birchwood Casey gun blue. To Me it's just watered down P?SS and doesn't really work that well.

I used products from this company when I made replica Webley oil cans, as I not only wanted to black the steel collar but darken the brass Valvespout assembly as well.

The Black Antiquing fluid contains Selenious Acid, and the Brown version contains Nitric Acid.

something I've looked into and a process called ebanol c is the best way
my mate showed me something called black magic ant that seemed to work and I'm told that oxy plus will black brass if it is boiled in it
I've not tried the oxy plus yet as i'll need to do it down the yard as it foams up a bit I was told
