Hi everyone. I was wondering if the borax in the box of “20 Mule Team
Borax” in my pantry is the same as the borax that is used as an
antioxidant and flux for melting precious metals. I was going to buy
some borax, but want to know if I already have some I can use. I
wonder if what I have might contain additives that would make it a
bad idea to use for jewelry making. Anybody know for sure?
