A large particle size kaolin of low plasticity. It is a secondary clay and has been mined since the 1940s. It is a moderately coarse grained clay that imparts more plasticity to a casting mix than similar clays produced by fractionation. It is used in sanitaryware, artware, generalware, floor tile, electrical porcelain, chemical porcelain and special refractories. In addition to improving casting properties, this material has excellent pressing properties.

This material is well crystallized with kaolinite being the predominant mineral. There is a trace of muscovite and less than 0.5% quartz.
