one question, are we talking oxidation or reduction? I'd love to find out, because at home I can only do oxidation, in class (when I sign up) it's reduction. Due to the fact that it's a 63 mile drive (one way), I've decided to stick closer to home and try to develop decent Cone 6 oxidation glazes.

If any of you who read this need a bed to sleep in during NCECA, we have an extra bedroom. We are only a few miles from the conference site and would enjoy the company.

This glaze just might be a stable glaze - that is a lot of cobalt however.

Expansion is a bit high but the crazing would be very hard to see.
