I would have a look for the following book, Firearm blueing & browning by R H Angier

I saw that in another thread, I ordered the book of evilbay already =D

Can you get your hands on 70% Nitric acid and Sulfuric acid?

Sulfuric acid isn't a problem. I'm not sure on nitric acid though. Chemical supply places stock it obviously, but im not sure if its something I will be able to purchase. if anyone on Oz has info on whether is can be brought without special licensing im all ears

2% ammonium chloride would be diluted in destilled water?
