Umcako osheshayo ngokuvamile uqukethe umcako oshisisa ngokweqile, ukugcinwa komcako oshisisa ngokweqile kuhamba kancane, uma umlotha womlotha wetshe uqina futhi, uzodala ukuqhekeka ngenxa yokwanda kokuguga.Ukuze uqede lo monakalo wokushiswa komcako, umcako kufanele futhi “uguge” cishe amasonto ama-2 ngemva kokulungiswa.Umumo umhlophe (noma umpunga, onsundu, umhlophe), u-amorphous, udonsa amanzi kanye ne-carbon dioxide emoyeni.I-calcium oxide ihlangana namanzi yakhe i-calcium hydroxide futhi ikhiphe ukushisa.Incibilika emanzini ane-asidi, ayincibiliki otshwaleni.Izindatshana ezonakalisayo ze-alkaline, ikhodi yengozi kazwelonke :95006.Umcako ubhekana namakhemikhali emanzini futhi ushiselwa ngokushesha emazingeni okushisa angaphezu kuka-100°C.
