CaCO3

This is the most common source of calcium in glazes. It is a high temperature flux that gives durability and hardness to glazes.

Whiting 325 mesh – standard material used in pottery glazes. 98.0 % CaCO3 with 1% retained on a 325 mesh sieve

Calcium Carbonate alone is quite refractory but when mixed with feldspar or silica will start fluxing around 1100C. It is often used in low fire clay bodies as an addition to help with glaze fit. It is rarely used as a flux in stoneware or porcelains. This is the Eastern Version of Calcium Carbonate.
