Hi
I'm trying to bet setup to blue small parts. I have used cold blue in the past with varying degrees of success. I would like to be able to achieve a more uniform finish. Anyone know where I can source gun bluing salts? I am considering using potassium nitrate but I don't want to buy something that is not pure enough.
