Formula: CaCO3

In stoneware glazes (cone 7-12), it promotes a matt finish and enhances chemical durability by producing 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 point of vitrification while decreasing porosity.
