No. 1 Glaze
No. 1 Glaze Clay is a very high kaolin bearing selection with extremely low levels of carbon content. it provides excellent suspension to all types of glazes especially glazes containing a high percentage of frit which has soluble alkali. No. Glaze provides viscosity control range and excellent rheology for all glaze application methods and especially bell or cone applications processes.
