Ngokusekelwe ohlelweni lwe-SiO 2-CAO -Na2O ternary, izithako zengilazi yebhodlela le-sodium ne-calcium zengezwa nge-Al2O 3 ne-MgO. Umehluko ukuthi okuqukethwe kwe-Al2O 3 ne-CaO engilazini yebhodlela kuphakeme kakhulu, kuyilapho okuqukethwe kwe-MgO kuphansi kakhulu. Kungakhathaliseki ukuthi hlobo luni lwemishini yokubumba, amabhodlela kabhiya, amabhodlela otshwala, amathini angasetshenziswa lolu hlobo lwezithako, ngokusho nje kwesimo sangempela ukwenza ukulungiswa okuhle.
Izingxenye zayo (ingxenye yobuningi) bezisukela ku-SiO 27% kuya ku-73%, A12O 32% kuya ku-5%, CaO 7.5% kuya ku-9.5%, MgO 1.5% kuya ku-3%, kanye no-R2O 13.5% kuya ku-14.5%. Lolu hlobo lokuqamba lubonakala ngokuqukethwe kwe-aluminium okumaphakathi futhi lungasetshenziswa ukulondoloza izindleko ngokusebenzisa isihlabathi se-silica esiqukethe i-Al2O3 noma ukusebenzisa i-feldspar ukwethula ama-alkali metal oxides. I-CaO+MgO inevolumu ephezulu kanye nesivinini sokuqina esisheshayo.
Ukuze uvumelane nesivinini somshini esiphezulu, ingxenye ye-MgO isetshenziswa esikhundleni se-CaO ukuvimbela ikristalu yengilazi ukuthi icwebezeliswe emgodini wokugeleza, indlela yokuphakelayo kanye nesiphakeli. I-Al2O3 emaphakathi ingathuthukisa amandla emishini nokuzinza kwamakhemikhali engilazi.
