Gypsum
Gypsum is a mineral found in the shape of crystals as well as masses called gypsum rock. It is a very soft sedimentary mineral found in deposits all over the world. In Michigan, it is mainly found in the lower peninsula where it is mined from open quarries and underground mines.
Uses: Gypsum is used in fertilizer, drywall, sheetrock, cement and plaster of Paris. It is also used in toothpaste and make-up.
Color: Gypsum can be white, light pink, or have no color at all.
Fun fact! Did you know? Gypsum contains water molecules that allows drywall made from it to offer greater fire protection than building materials without it.
