Similar to garnet, wollastonite is a silicate mineral fairly widespread in its distribution. It was named in honor of the English scientist William Hyde Wollaston, who, in addition to his important discovery of dark lines in the solar spectrum and other notable achievements, created an endowment to be granted annually by the Geological Society of London. Wollastonite crystals typically appear glassy white, but may occasionally be found in shades of gray. The mineral is most commonly utilized in ceramics and paints.
