Crystal glazes are normally evaluated on the recipe level, people simply have a recipe that they know works and add colors to it. However there is a great benefit to knowing why crystals grow the way they do and what explains the variations in size, shape, color, etc.
|GRNTCG-GRANITE Crystalline Glaze
A type of ceramic glaze made by potters. Giant multicolored crystals grown on a super gloss low alumina glaze by controlling multiple holds and soaks during cooling
Glass vs. Crystalline
In ceramics, understanding the difference between what a glass and crystal are provides the basis for understanding the physical presence of glazes and clay bodies.
Ceramic glazes form crystals on cooling if the chemistry is right and the rate of cool is slow enough to permit molecular movement to the preferred orientation.
