KAOLIN INFORMATION

Kaolin, also known as china clay, has a great number of uses. These include: ceramics, filler, pharmaceutical, absorbent, and many others.

Grades of KAOLIN

Kaolin Calcined Clay

KAOLIN CALCINED CLAY INFORMATION

This is a white clay which has been subjected to very high temperatures. This thermal treatment is strong enough to rearrange the crystal structure, creating a new product not seen in nature.
