Pre-treating crucibles

        The stuff works great for pre-treating crucibles and is
also a great detergent booster. 

How do you use the Borax to pre-treating your crucible?

How do you use the Borax to pre-treating your crucible?

I just heat the crucible with a torch and spoon in borax. While the
torch is still directed at the crucible, I turn and rotate it so that
the entire inner surface is coated. Then I tilt the crucible and
pour the excess molten borax out into the quench bucket. This gives
the crucible a very slick surface that gold won’t stick to.
