This product is available from a variety of suppliers, (e.g.. Unimin Corp) and is useful as an inexpensive grog in clay bodies. The material has several advantages over traditional grog:
-It is available in select size ranges (e.g. 20-40 mesh)
-The particle shape is angular
-It is very inexpensive
On the minus side, the particles are hard and thus wear on trimming tools, pugmills, etc. will be greater. The particles are not absorbent, so the material will not route water to the surface during drying as well as traditional ground brick grog. Also, this is pure silica, so the dust hazard is greater.

Quartz is one of the most dangerous materials used in ceramics, yet it is irreplaceable. It is the most abundant mineral on earth, we must learn to use it safely.
Quartz is the main crystalline mineral form of silica (SiO2). White or milky quartz is an opaque white, greasy-looking, sharply angular very hard rock. Natural deposits of relatively pure quartz are p...
