How did the mineral gypsum get its name?

Gypsum (Hydrous Calcium Sulfate) The name gypsum comes from a Greek work meaning calcined or burned. Selenite, a variety of gypsum with colorless, clear crystals, gets its name from a Greek word for moon. Although generally a common mineral, gypsum has very limited production in Ohio.

How Is Gypsum Formed?

How is gypsum made? Gypsum is made up of oxygen, sulfur, calcium and water. As evaporation occurs the sulfur is not protected by the water and oxygen contacts sulfur bonding with it to form a sulfate (SO4 2). The sulfate then bonds with calcium (Ca) and water (H2O) to create gypsum.
