Whiting, Calcium Carbonate

SKU SKU 166 Categories ,



Whiting- Calcium Carbonate – CaCO3 (m.p. 4650o F/2570o C) is a finely ground powder composed essentially of pure Calcium Carbonate derived from Limestone, Chalk, or Marble. It is the most common source of Calcium in a glaze and clay body. In stoneware glazes (cone 7-12), it promotes a matt finish and produces a harder and more chemically resistant glaze. In stoneware bodies (cone 7-12) it acts as a flux (typically >3%), and it will increase shrinkage and strength by lowering the vitrification point and decreasing porosity.
