Ana kuma kiran Calcium sulfate da raw gypsum, gypsum mai tauri, Muriacite, gypsum mai anhydrous. Lu'ulu'u marasa launi (nau'in β) ko lu'ulu'u na monoclinic (nau'in α). Nauyin kwayoyin halitta 136.14. Yawan dangi 2.960. Wurin narkewa 1193℃ (wanda aka canza daga nau'in β zuwa nau'in α), 1450℃ (nau'in α, kuma ya ruɓe). Yana narkewa kaɗan a cikin ruwa (0.209 a 20℃), yana narkewa a cikin acid, gishirin ammonium, sodium thiosulfate, maganin sodium chloride da glycerol. Ko da an ƙara ruwa, ba zai iya sake zama calcium sulfate dihydrate ba. Idan ma'adinin gypsum na halitta ya bushe gaba ɗaya ƙasa da 300℃, ana iya samar da gypsum mai narkewa wanda ke narkewa a cikin ruwa; idan an dumama gypsum na halitta zuwa sama da 600℃, ana samar da gypsum mai narkewa wanda ba ya narkewa a cikin ruwa. Lokacin da aka haɗa calcium sulfate ko plaster na Paris da ruwa mai dacewa, yana taurare a hankali. Ana amfani da shi azaman abin hana ruwa, mannewa, mai shan danshi, foda mai gogewa, cika takarda, busar da iskar gas, bandeji na filastik, da kuma aikin hannu.
