How to Convert Kaolin to Calcined KaolinSue McLeod

 · The Solution. The solution is to replace some of the clay with calcined clay. Calcining is where the kaolin is fired to a temperature hot enough to remove the chemically bound water molecules from the clay particles. KaolinAl 2 O 3 ·2SiO 2 ­·2H 2 O → Al 2 O 3 ·2SiO 2 ­Calcined Kaolin. This pre-shrinking of the clay reduces the shrinkage of the glaze as it dries and as it s
