Rock gypsum is a chemical sedimentary rock. It forms by the evaporation of water (usually seawater) and the precipitation of dissolved minerals. Rock gypsum, unlike rock salt, does not have a salty taste, and is softer. Rock gypsum’s color is often a white, gray or brownish. It is usually microcrystalline and powdery looking. Rock gypsum superficially resembles chalk. Chalk is calcitic, and so will bubble in acid.
