Notes. Kaolin is pure clay mineral, having a fired chemistry of 1 molar part Al 2 O 3 and 2 parts SiO 2.However the raw clay crystals are hydrated, having 12% crystal-bound water. This is the secret to their plasticity.Calcining the material removes that water and alters the particle structure and shape, thus destroying the plasticity.
