How do you get this to fire without blistering?
Cryolite is a notorious source of gases during
firing isn\'t it? I have found my cryolite to be
an unbelievably active melter, it eats right
through the clay in a test. Also, what about
fluorine fumes with this, is it safe to use?
I have no experience with this material.
