This is the most common grade used in ceramic wall and floor tile, in glazes, and in frits for glazes and enamels. It also finds use in glaze and body stains, in bonds for vitrified grinding wheels, in electrical insulators, and as an auxiliary flux.

Different grades of the material vary in particle size (especially in the +325-200 range)

Density Mg/m3: 2.9
Weight (lbs/gal): 24.2
pH at 10% solids: 10-11
GE Brightness: 83
Hegman Fineness: 4
+325 mesh: 0.03%

W-10 has similar data except it is 19% +325 mesh (200 mesh grade). W-20 is 2.5% +325 mesh.
W-C-1 and DFSP are crushed.
