This is a secondary kaolin with an intermediate particle size distribution. It is primarily used in plastic forming processes where its particle size distribution and montmorillonitic mineralogy serves to impart green strength to the body. It contains low Fe2O3 and TiO2 content for applications where fired color is critical. It has also proven useful in glaze applications.
