Physical and Chemical Properties of Gypsum Mineral Gypsum was known as Spear Stone in old English since it takes a crystal-like form, projecting out of a rock like a spear. You can mill mix gypsum with water to get its original rock-like shape, and it can be hardened Properties of Gypsum ★ Gypsum is a soft mineral, that is moderately soluble in water. The water solubility of this mineral is affected by temperature. Unlike other salts, gypsum becomes less soluble in water as the temperature increases

Gypsum Mineral Uses and Propertie

  1. Gypsum is found in a number of forms and is of great economic importance. It is colorless or white but can be tinted light brown, gray, yellow, green, or orange due to the presence of impurities. Single, well-developed crystals can be blocky with a slanted parallelogram outline, tabular, or bladed
  2. Gypsum is composed of hydrated calcium sulphate and takes many forms, occurring as tabular, bladed and diamond shaped crystals. it also occurs in fibrous form, and in compact, granular masses, and as rosette shaped aggregates with included grains of sand. Gypsum varies from colourless to white, gray, yellowish, reddish, greenish, and brown

Physical properties. Gypsum (CaSO 4 · 2H 2 O) has a specific gravity of 2.32 and hardness of 2. It is commonly colorless, white, or gray. Shades of yellow, red, and brown result from impurities. Crystals, when present, are generally of tabular or prismatic habit and crystallize in the monoclinic system Gypsum is a hydrous, soft sulfate mineral, specifically a calcium sulfate dihydrate, which means it has two molecules of water in its chemical composition. This is seen in its chemical formula is CaSO 4 2H 2 0. When gypsum is heated and the water within the mineral is evaporated out, gypsum turns into a chalk or plaster, known as plaster of Paris Gypsum is a natural insulator, feeling warm to the touch when compared to a more ordinary rock or quartz crystal. Sheets of clear crystals can be easily peeled from a a larger specimen. Gypsum crystals can be extremely large - among the largest on the entire planet. A cave in Naica, Mexico contains crystals that dwarf the people inside

While both gypsum and anhydrite are basically calcium sulfate, the presence or absence of water molecules makes a big difference in their physical properties. At Mohs 1.5-2.0, gypsum is much softer than anhydrite (Mohs 3.0-3.5). The reason is that gypsum's attached water molecules increase the distance between its calcium ions and sulfate.
