White or yellowish, finely divided, odorless powder consisting mostly or entirely of calcium sulfate hemihydrate, CaSO4*1/2H2O. Forms a paste when it is mixed with water that soon hardens into a solid. Used in making casts, molds, and sculpture. Generally non-toxic.
Chemical Formula: CaSO4 = 0.5H2O
Water Solubility: 0.3 % at 77° F (NIOSH, 2016)
Specific Gravity: 2.5 (NIOSH, 2016)
Molecular Weight: 145.2 (NIOSH, 2016)
