Hydration Of Anhydrite: Gypsum could also sort with the hydration of anhydrite (CaSO₄). Anhydrite is actually a calcium sulfate mineral that lacks the drinking water molecules current in gypsum. When subjected to h2o, anhydrite undergoes a hydration response, incorporating water molecules into its construction and remodeling into gypsum.
