Ho ipapisitsoe le SiO 2-CAO -Na2O ternary system, metsoako ea khalase ea botlolo ea sodium le calcium e kenyelletsoa ka Al2O 3 le MgO. Phapang ke hore litaba tsa Al2O 3 le CaO ka khalase ea botlolo li batla li le holimo, athe litaba tsa MgO li batla li le tlase. Ho sa tsotellehe hore na ke mofuta ofe oa lisebelisoa tsa ho bōpa, libotlolo tsa biri, libotlolo tsa joala, makotikoti a ka sebelisoa mofuta ona oa metsoako, feela ho ea ka boemo ba sebele ho etsa tokiso e ntle.
Likarolo tsa eona (karolo ea boima) li ne li tloha ho SiO 27% ho ea ho 73%, A12O 32% ho 5%, CaO 7.5% ho 9.5%, MgO 1.5% ho 3%, le R2O 13.5% ho 14.5%. Mofuta ona oa sebopeho o khetholloa ka lintho tse itekanetseng tsa aluminium 'me o ka sebelisoa ho boloka litšenyehelo ka ho sebelisa lehlabathe la silica le nang le Al2O3 kapa ho sebelisa feldspar ho hlahisa li-oxide tsa alkali metal oxides. CaO+MgO e na le molumo o phahameng le lebelo le thata le thata.
E le ho ikamahanya le lebelo le phahameng la mochine, karolo ea MgO e sebelisoa sebakeng sa CaO ho thibela kristale ea khalase hore e se ke ea khanya ka har'a lesoba la phallo, tsela ea ho fepa le ea ho fepa. Al2O3 e itekanetseng e ka ntlafatsa matla a mochine le botsitso ba lik'hemik'hale tsa khalase.
