Silica (Flint) 200 Mesh

Silica (Flint) 200 Mesh is a purified version of this much used material of glaze and claybody formulation. In clay and glazes, Flint provides the melting, or glassifying agents in a claybody that allow the material to fuse together.

Flint is used for hardness in glazes, and decreases thermal expansion. In claybodies, the expansion factor is exactly the opposite -- an increased presence of silica increases the thermal expansion.

Note: 200 Mesh is most commonly found in clay bodies, while 400 Mesh is used for glazes. See our Safety Data Sheets section under Customer Service for a downloadable copy of the SDS for this product.
