Calcite (Whiting) Omy Carb 10
In low-fire bodies, calcium carbonate is sometimes added in small amounts as a filler to reduce fired shrinkage and act as a whitener. It is also common to see 5% Whiting included in porous earthenware body recipes to prevent moisture expansion (which causes glazes to craze).Whiting is used in some pottery bodies. Under reducing conditions, it assists in the development of celadon colour. An excess will give a matt, dull or rough surface, especially in low-fired glazes.
