Al2O 3 na MgO byongeweho hashingiwe kuri sisitemu ya ternary ya SiO 2-cao-na2o, itandukanye nikirahure cya plaque kuko ibiri muri Al2O 3 biri hejuru kandi ibiri muri CaO biri hejuru, mugihe ibiri muri MgO biri hasi.
Ntakibazo cyubwoko bwibikoresho bibumba, byaba amacupa yinzoga, amacupa yinzoga, amabati arashobora gukoreshwa mubwoko bwibigize, gusa ugomba gukora neza neza ukurikije uko ibintu bimeze. Ibigize (igice kinini) ni: SiO 27% ~ 73%, A12O 32% ~ 5%, CaO 7.5% ~ 9.5%, MgO 1.5% ~ 3%, R2O 13.5% ~ 14.5%.
Ubu bwoko bwibigize burangwa nibintu bya aluminiyumu iringaniye, gukoresha Al2O3 irimo umucanga wa silika, cyangwa kwinjiza oxyde ya alkali hamwe na feldspar kugirango uzigame ibiciro. Umubare wa CaO + MgO ni mwinshi, kandi umuvuduko ukomera urihuta cyane, kugirango uhuze n’umuvuduko mwinshi w’imashini, igice cya MgO gikoreshwa mu mwanya wa CaO kugirango wirinde ikirahuri koroha mu mwobo w’amazi, kugaburira imashini yo kugaburira no kugaburira. Moderate Al2O3 irashobora kunoza imbaraga za mashini hamwe nubumara bwimiterere yikirahure.
