I am a gunsmith and have been restoring and re-bluing weapons for 12 years now with no issues. I have used Brownells Oxynate 7 with great success. Problem lately is Brownells hasn't had any salts to sell since I tried re-ordering last September. I need salts. So I found two old recipes for mixing my own salts and bought the components.
I am in need of some advice from someone who knows the proper mix for a home made tank mix. I have used Sodium hydroxide and Sodium Nitrate for my mix.
The 1st tank I used the mix was 5 parts sodium Hydroxide to 4 parts Sodium Nitrate to 1 gal. water. The parts came out very blochy and slightly brown in color The temp. was 265. I re-did my salts and tried it at 5 parts Sodium Hydroxide to 2 1/2 parts Sodium Nitrate to 1 gal. water. Same results.
I have never mixed my own product before so any advice will be of great help.
I have 14 weapons to blue right now and am in a pickle.
