Calcium carbonate (Whiting) is another main component in the production of ceramics. Calcium carbonate is an economical source of calcium oxide, which is needed as a melting agent at high temperatures, improves the mechanical and chemical strength of the glass body, and reduces shrinkage from firing.

Calcium Carbonate (Limestone) stabilizes glass, solving the issue of solubility and increases its hardness and chemical durability. It also plays a role in lowering the melting temperature of the batch by improving the melting kinetics.
