Wollastonite - Wikipedia

Wollastonite is a calcium inosilie mineral (Ca Si O 3) that may contain small amounts of iron, magnesium, and manganese substituting for calcium. It is usually white. It forms when impure limestone or dolomite is subjected to high temperature and pressure, which sometimes occurs in the presence of silica-bearing fluids as in skarns or in contact with metamorphic rocks.

Calcium Carbonate Suppliers, CAS No.471-34-1

Calcium carbonate is known as whiting, and it is commonly used for many glazes in its white powdered form. The whiting acts as a flux material in the glaze when the glaze is fired in a kiln. Ground calcium carbonate will not scratch most materials such as glass and ceramics and have a moderate effect on softer metals such as copper.
