Silica 200# AU

Silica 200#

Also known as Quartz or Flint.

The most common component used in glazes and bodies. 
This material gives glazes their glassy appearance. It is available in various mesh sizes from 30, 200 & 350 mesh.
It raises the melting point of glazes, and decreases thermal expansion. By contrast, it will increase thermal expansion in clays.
