O lona hemihydrate e masani ona taʻua o le "gypsum mu" ma le "platinum calciformis", e tele lava i foliga o le paʻepaʻe paʻepaʻe e le o le tioata, faatasi ai ma le maualuga o le 2.75. O lona dihydrate e masani ona taʻua o le "gypsum", o le tioata paʻepaʻe poʻo le paʻu, faʻatasi ai ma le maualuga o le 2.32, faʻamaufaʻailoga 1.521, 1.523, 1.530, ma leiloa uma vai tioata pe a vevela i le 163 ℃. Tusi vaila'au E solu teisi i le vai, hydrochloric acid, nitric acid, soluble i le vevela sulfuric acid, e le mafai ona solu ile ava malosi. O oloa faanatura e mafai ona solu i le alkaline sulfate, sodium thiosulfate, ma vaifofo vai masima ammonium. Sauniuniga auala: E maua le gypsum anhydrous faanatura e ala i le tali atu o le CaO ma le SO3 i lalo ole vevela mumu. Soluble anhydrous gypsum e maua e ala i le vevela CaSO4 · 2H2O i le mamafa tumau i le 200 ℃. O le Hemihydrate e maua e ala i le faʻamaʻaina ma le faʻamaʻaina o le gypsum mata. E maua le dihydrate e ala i le taliina o le calcium chloride ma le ammonium sulfate. Fa'aoga autu o le calcium sulfate: O le gypsum anhydrous masani e masani ona fa'aaogaina i vailaau; soluble anhydrous gypsum e mafai ona faʻaaogaina e fai ma teuteuga i totonu, ma e mafai foi ona faʻaaogaina e fai ai vailaʻau, meainu, ma isi; o le hemihydrate e masani ona faʻaaogaina i mea faufale, ma e mafai foi ona faʻaaogaina e fai ai faʻatagata gypsum ma mea faʻamea; o lona dihydrate e faʻaaogaina e fai ai le hemihydrate, faʻatumu, ma isi.
