The hydrated raw clay crystals are 12 per cent crystal-bound with water, which is how they are so flexible. As a result, Kaolin is an excellent source of Al2O3, which helps to chemistry the vast majority of glazes. Calcined Kaolin can be used in a wide variety of ceramics applications. It is brittle and softens around cone 35.
