Calcined Kaolin Ceramic Arts Network

If kaolin is calcined at too high a temperature, say cone 04, the resulting calcine can contain hard lumps of clay. Such lumps don’t distribute their alumina and silica content as thoroughly within the glaze matrix. These lumps can only be broken up by grinding. Industry has found that calcining kaolin
