Gypsum - Wikipedia

Gypsum is moderately water-soluble (~2.0–2.5 g/l at 25 °C) and, in contrast to most other salts, it exhibits retrograde solubility, becoming less soluble at higher temperatures. When gypsum is heated in air it loses water and converts first to calcium sulfate hemihydrate, (bassanite, often simply called "plaster") and, if heated further, to anhydrous calcium sulfate ().

Nov 18, 2019  Anhydrous calcium sulfate (drierite) is one of the few desiccants that can be safely used to dry acetone, as most common desiccants tend to cause it to self-condense. Neutral calcium sulfate (no traces of bisulfate or hydroxide) is necessary, as any impurities like bisulfate or hydroxide will cause minor self-condensation.
