Elements that Form Gypsum. Gypsum. 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. Video of the Day.
