What is pure gypsum?
Pure gypsum is a white rock but sometimes impurities colour it grey, brown or pink. Its scientific name is calcium sulphate dihydrate and its chemical formula is CaSO42H2O. This means that, for every molecule of gypsum, there are two molecules of water. This is a most important fact in the gypsum story.
What type of rock is gypsum?
Gypsum is a mineral found in crystal as well as masses called gypsum rock. It is a very soft mineral and it can form very pretty, and sometimes extremely large colored crystals. Massive gypsum rock forms within layers of sedimentary rock, typically found in thick beds or layers.

Where do we get gypsum?
Gypsum is deposited from lake and sea water, as well as in hot springs, from volcanic vapors, and sulfate solutions in veins. Hydrothermal anhydrite in veins is commonly hydrated to gypsum by groundwater in near-surface exposures. It is often associated with the minerals halite and sulfur.
Is gypsum a lime?
Lime vs gypsum Lime is a carbonate, oxide or hydroxide of calcium. … Gypsum is calcium sulphate. It is also used to provide calcium ions in the soil, but does not have the effect of increasing soil pH. Gypsum is in fact a neutral salt, and therefore is used on soils with pH’s of greater than 7.
