The Polar Ice data sheet has been changed. In the past we have been hesitant about firing it over cone 6. This is because it is just so vitreous and translucent that firing it higher seemed to be asking for trouble (like warping, blistering). But at cone 10R it is still resistant to warping. And fires this beautiful blue-white. The translucency, amazingly, is about the same: Incredible! This is among the most incredible pieces we have ever made in the studio here, it is hard to believe it is possible produce this kind of quality in a pottery studio.
