A gypsum block is made of gypsum plaster and water. The manufacturing process [1] is automated at production plants where raw gypsum (CaSO 4 ·2H 2 O) is ground and dried, then heated to remove three-quarters of the bound water and thus transformed into calcium sulfate hemihydrate (CaSO 4 ·½H 2 O), also known as gypsum plaster, stucco, calcined gypsum or plaster of Paris.
Homasote was widely used as wall sheeting from the 1940s into the 1970s. Due to the development of more fire-resistant gypsum board, it has decreased in popularity as a wall sheeting.
