Rock salt is the name of a sedimentary rock that consists almost entirely of halite, a mineral composed of sodium chloride, NaCl. It forms where large volumes of sea water or salty lake water evaporate from an arid-climate basin -- where there is a replenishing flow of salt water and a restricted input of other water.Gypsum is a soft sulfate mineral composed of calcium sulfate dihydrate (CaSO 4 ·2H 2 O). It is generally found in the form of rock and is white in color. Gypsum plaster is a paste formed by mixing the gypsum powder and water in a suitable proportion.
