- A naturally occurring mineral of approximately 2/3 alumina and 1/3 silica. In most clay bodies, it is an inert grog of high quality and consistency. The grog particle is not round, but elongated, allowing greater blending with the clay matrix to improve strength and thermal shock resistance. A gray colored particle.
- WARNING: Contains free crystalline silica, which could lead to silicosis or other lung diseases after very long exposure. IRAC has classified crystalline silica as a carcinogen, based on evidence of carcinogenicity in experimental animals and limited evidence of carcinogenicity to humans. Wear a NIOSH approved respirator. For further information, contact: Rovin Ceramics at 734/424.3345
