All About Wollastonite

Wollastonite is a little-known but extremely useful calcium-silicate mineral (CaSiO3) created when impure limestone, often in the presence of silica-bearing metamorphic rock, is subjected to high temperature and pressure. It is a relatively rarely-occurring mineral and is produced in a few places worldwide with only 3 mines in North America offering the product.
