Gypsum is a very soft sulfate mineral composed of calcium sulfate dihydrate, with the chemical formula CaSO4•2H2O. It is found in alabaster
Gypsum is moderately water-soluble (~2.0–2.5 g/L at *5 °C) and, in contrast to most other salts, it exhibits a retrograde solubility, becoming less soluble at higher temperatures. When the crystal lattice is heated it loses liquid water molecules to evaporation and thus gains solidity.
, Gypsum is hydrated calcium sulfate formed by the evaporation of brines , near to sea then hydration ,
