Material Notes:

This is a very high quality porcelain grade ball clay. It has fine particle size distribution for excellent plasticity and strength in pressing or plastic forming application. the low Fe2O3 and TiO2 provide high fired brightness to vitreous ceramic compositions. M-23 also has low carbon content for excellent oxidation qualities.Information provided by Old Hickory Clay Company
