GF-K21 kaolin clays is designed specifically for customers who wish to prepare quality glazes,casting slips or plastic bodies. 

With our unique combination of particle size  distribution, rheology and mineralogy, GF-K21 will improve casting rate and deflocculant response in traditional, automated and pressure cast applications. 

All grades are low in residue and carbon, and provide excellent suspension properties, stable viscosity and improved plasticity.  

All GF-K21 Kaolin grades are mined, processed and sized under rigid quality assurance programs.  

The result is consistent chemistry and rheology and uniform particle size distribution for a  controlled casting rate andpredictable firing performance.
