What matters
The parametersthat matter here
Feldspar melts during firing and binds the tile body; quartz adds silica, which strengthens the body and helps control shrinkage. We supply both, in 100 to 300 mesh.

Mesh grades
Four grades,potash and soda
A higher mesh number means a finer powder. All four grades are available in potash and soda types.
