Calcium carbonate provides the main source of calcium oxide needed for ceramic production, calcium oxide melts at 1,050oC, which improves the mechanical and chemical strength of the glass body and reduces shrinkage from firing.
Calcium carbonate is mixed with large quantities of ceramic to achieve the necessary expansion for the correct ratio between the ceramic piece and the glaze. Calcium carbonate is one of the two main ingredients in silica ceramic and a source of calcium oxide.
