Dimension stone - Wikipedia
Dimension stone is natural stone or rock that has been selected and finished (e.g., trimmed, cut, drilled, ground, or other) to specific sizes or shapes. Color, texture and pattern, and surface finish of the stone are also normal requirements. Another important selection criterion is durability: the time measure of the ability of dimension stone to endure and to maintain its essential and

Veins. Gypsum veins are of the variety often known as selenite, in which the gypsum is crystalline and glassy, occasionally taking a finely columnar form, known as satin spar. Such veins are formed by the solution of gypsum from the surrounding rocks or from other deposits, the material being reprecipitated in cracks through the rocks.

Purity Determination in Gypsum Application Note Gypsum
Natural Gypsum Gypsum is a mineral found in natural rock. It is extracted either by quarry ing or mining. Pure gypsum contains 79.1% calcium sulfate (CaSO 4) and 20.9% chemically bound water (H 2O). However, since gypsum is a natural material, pure gypsum is rarely found. Natural gypsum typically contains up to 15 to 20% impurities such as lime,

Gypsum - Chemical Formula, Properties, Types, Uses and FAQ
Gypsum rock is first mined or quarried, then crushed and ground to a fine powder. It then goes through a process called calcining where heat at 350 degrees is supplied to the gypsum powder which removes 3/4th of the water molecules. Hemihydrate is the name of calcined gypsum which is then used in gypsum board, gypsum plaster, and other products.
