Calcined Kaolin
Kaolin is pure clay mineral, having a fired chemistry of 1 part Al 2 O 3 and 2 parts SiO 2. But the raw clay crystals are hydrated, having 12% crystal-bound water. This is the secret to their plasticity. Al 2 O 3 is essential to the chemistry of the vast majority of glazes and kaolin is ideal source material. Calcined kaolin has many other uses ...
