Yeah,gidday everyone.
I have a few bluing formulas I have gathered but they all seem to use ammonium nitrate.
I can get my hands on only urea.
Can it be substituted ?
I have cal nitrate and pot nitrate as well.
Do I just pee on a barrel and let it rust then steam?
I tried hot blue caustic soda or something tanks many years ago and it did work but no thanks,not again.
Some of the bought solutions are unavailable over here and I’d rather do it myself anyway.
Any ideas for a cold/ rust blue quick or slow using easy find components.
I tried some sea salt and peroxide solution and let it rust then boiled it and it turned out a bit pity antqueekish pitted neglected looking on some steel which would favourably blend in with some of my guns.....but after something a bit more better.
Thnx
Bruce
