Ngokusekelwe kwinkqubo ye-SiO 2-CAO -Na2O ternary, izithako zeglasi ze-sodium kunye ne-calcium zongezwa kunye ne-Al2O 3 kunye ne-MgO. Umahluko kukuba umxholo we-Al2O 3 kunye ne-CaO kwiglasi yebhotile iphezulu, ngelixa umxholo we-MgO uphantsi. Kungakhathaliseki ukuba luhlobo luni lwezixhobo zokubumba, iibhotile zebhiya, iibhotile zotywala, iitoti zingasetyenziswa ngolu hlobo lwezithako, ngokuhambelana nemeko yokwenyani ukwenza ukulungiswa kakuhle.
Amacandelo ayo (i-mass fraction) ukusuka kwi-SiO 27% ukuya kwi-73%, i-A12O 32% ukuya kwi-5%, i-CaO 7.5% ukuya kwi-9.5%, i-MgO 1.5% ukuya kwi-3%, kunye ne-R2O 13.5% ukuya kwi-14.5%. Olu hlobo lokubunjwa lubonakaliswa ngumxholo we-aluminium ophakathi kwaye lungasetyenziselwa ukugcina iindleko ngokusebenzisa isanti ye-silica equkethe i-Al2O3 okanye ukusebenzisa i-feldspar ukuzisa i-alkali metal oxides. I-CaO+MgO inomthamo ophezulu kunye nesantya sokuqina ngokukhawuleza.
Ukuze ulungelelanise nesantya esiphezulu somatshini, inxalenye yeMgO isetyenziswa endaweni ye-CaO ukukhusela ikristale yeglasi ukuba ifakwe kwi-crystallized kwi-flow hole, indlela yokutya kunye ne-feeder. I-Al2O3 ephakathi inokuphucula amandla omatshini kunye nokuzinza kweekhemikhali zeglasi.
