calcium sulfate
Quick Summary
Calcium sulfate (CaSO4) is a white salt that occurs in nature in various forms, including anhydrite and gypsum. In its hydrated form, it is used as a building material, and in its anhydrous form, it serves as a drying agent. Anhydrite, a mineral form of calcium sulfate, is found in evaporite deposits and is used in plasters and cement. Calcium is a metallic element abundant in Earth's crust and is essential for life. Calcium sulfate compounds are found in nature and have various industrial applications.123

ale…brewed with water rich in calcium sulfate, are made with top-fermenting yeast, and are processed at higher temperatures than the lagers popular in the United States. Pale ale has up to 5 percent alcohol content, while India pale ale—a variety of pale ale—typically has more; both usually have even stronger…
