Greetings group.
Does anyone know anything about the chemical make-up of gun blue?
I have used it for years to identify stainless steel(a little bit on the end of a needle). Finally someone asked me questions about it and I had no idea.
Is there another way to quickly identify whether something is stainless steel or not?
Thanks!
