Molochite is highly calcined low iron mineral consisting of 55% Mullite and 45% amorphous glass. This material is very white in color and ground to a number of specifications. It is an excellent addition to porcelains as a grog material.
Molochite can be used individually or in combination but seldom totaling more than 40% of the total clay body weight. Courser material is generally used for larger more textured work, finer for smaller smoother works.
