Gypsum is a sulfate mineral, containing calcium and sulfur. It is in fact the most common sulfate mineral. It is widely used as a material for making drywall boards for house construction (sheetrock). It is also used for making plaster of Paris.

石膏是一种含钙和硫的硫酸盐矿物，实际上是最常见的硫酸盐矿物。它被广泛用于制造用于房屋建筑的干壁板（纸面石膏板）。它也用于制造巴黎石膏。

Gypsum is one of the softest minerals, measuring 2 on the Mohs hardness scale. It can be scratched with a fingernail.

石膏是矿物中硬度最软的之一，莫氏硬度为2。它可以被指甲划出痕迹。
