Description
 

Old Hickory Number 1 GLAZE CLAY


# 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. Number 1  Glaze provides viscosity control range and excellent rheology for all glaze application methods and especially bell or cone applications processes.

Old Hickory No. 1 Glaze is domestically and internationally accepted as the best clay for all glaze applications. The No. 1 Glaze clay is virtually carbon free (less than 0.1%) yet provides film strength that can withstand all overglaze techniques.

No. 1 Glaze clay has excellent suspension qualities which provide extended shelf-life for unused glaze. The high suspension value of the No. 1 Glaze clay combined with the excellent strength allows you to minimize, or eliminate expensive additives such as gums or binders.

The No. 1 Glaze clay has excelled in spraying, dipping, brushing, discoing and bell waterfall applications.

It is a ball clay mined in Kentucky . It is a fine ball clay (< 55%, <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). It is recommended by Ferro for use in fritted glazes.
