Wollastonite Wikipedia

Wollastonite is a calcium inosilicate 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.

Wollastonite's greater readiness to melt at higher temperatures has a curious side effect: Glazes can tolerate higher SiO 2 (from the Wollastonite) and melt just as well or better. In glass and stone making wollastonite melts more readily (lower energy costs) and microbubble generation is lower than limestone-sand mixes.

Wollastonite Article about Wollastonite by The Free

Wollastonite crystallizes in a triclinic system, forming flat tabular crystals as well as radiated and conchoidal aggregates; its color is white and sometimes pink. It has a hardness of 5-5.5 on the mineralogical scale and a density of 2,780-2,920 kg/m 3. Wollastonite is formed by contact and plutonic regional metamorphism of limestones.
