It provides excellent suspension to all types of glazes especially glazes containing a high percentage of frit which has soluble alkali. Number 1 Glaze provides viscosity control range and excellent rheology for all glaze application methods and especially bell or cone applications processes.\u003c\/p\u003e\n\u003cp\u003eOld Hickory ball clay is domestically and internationally accepted as the best clay for all glaze applications.

It is a fine ball clay (\u0026lt; 55%, \u0026lt;1 micron) used in clay bodies to add plasticity and improve strength. In a glaze, it is a source of Alumina and will enhance glaze suspension (see also Ball Clay).
