As its name suggests, natural gypsum is mineral found in nature. Large Gypsum Deposits occur in many countries. They have form by crystallization of Saturated aqueous solutions in shallow marine areas. During this process, inversely to their solubility sequence, first the carbonates, then sulfates and finally chlorides deposited. This lead to the formation of gypsum deposits with thickness of a few meters up to, in exceptional cases, 400 meters. This deposits first consisted of gypsum. As a result of other storing sedimentation on the top of the gypsum and the corresponding rise in temperature, the gypsum (CaSO4 2H2O) was converted to anhydrite (CsSO4) so that the calcium sulfate deposits from the geological past consisted almost entirely of anhydrite.
Because of the geological history, gypsum rocks differs in terms of purity, color and rock fabric. On the MOH’s scale of mineral hardness, gypsum has hardness of 1.5 – 2.0. The density of gypsum rock is 2.2 – 2.4 kg/m2. Natural impurities are sediments which settled out together with the gypsum in the marine basins, such as Limestone, Marl, Clay and sometimes Sands, Bitumen or various saltes. Some of these natural impurities impart specific benefecial building physical properties to the products made from these materials, such as gypsum plasterboard.
