Construction plaster, gypsum wallboard

The most widely used form of calcium sulfate is the dihydrate, gypsum, which is an important raw material in the construction industry. It is used in the manufacture of Portland cement, in specialized plasters (known as gypsum plasters) for walls, in the production of wallboard, and in cement blocks and mortars. Gypsum is also used extensively in agriculture as a conditioning agent that adds both calcium ions (Ca2+) and sulfate ions (S042-) to the soil. The compound is also used as a raw material in the synthesis of other calcium compounds and in the production of plaster of Paris. 

The other type of ceramic material that came to be used is gypsum. Today, gypsum is used to make wallboards, molds, sculptures, and casts. Plaster of Paris, as the set gypsum is called, was used in ancient times in construction. It was also used to mold the front of the skull to depict the features of a dead person in the family.
