This ball clay is a multi- purpose clay that has excellent pressing, extrusion, and casting qualities. It has a moderately fine particle size distribution and the high plasticity and dry strength is due in part to unique mineralogy of the clay. The low total carbon content provides excellent oxidation characteristics to a variety of ceramic process formulas.
