Ukurikije sisitemu ya ternary ya SiO 2-CAO -Na2O, ibikoresho bya sodium na calcium icupa ryibirahure byongewemo na Al2O 3 na MgO.Itandukaniro nuko ibiri muri Al2O 3 na CaO mubirahure by'icupa biri hejuru cyane, mugihe ibiri muri MgO biri hasi.Ntakibazo ubwoko bwibikoresho bibumba, amacupa yinzoga, amacupa yinzoga, amabati arashobora gukoreshwa mubwoko bwibigize, ukurikije uko ibintu bimeze kugirango ukore neza.
Ibigize (igice kinini) kuva kuri SiO 27% kugeza 73%, A12O 32% kugeza 5%, CaO 7.5% kugeza 9.5%, MgO 1.5% kugeza 3%, na R2O 13.5% kugeza 14.5%.Ubu bwoko bwibigize burangwa nibintu bya aluminiyumu iringaniye kandi birashobora gukoreshwa mu kuzigama ibiciro ukoresheje umucanga wa silika urimo Al2O3 cyangwa ukoresheje feldspar kugirango umenyekanishe oxyde ya alkali.CaO + MgO ifite amajwi menshi kandi yihuta cyane.
Kugirango uhuze n'umuvuduko mwinshi wimashini, igice cya MgO gikoreshwa mu mwanya wa CaO kugirango wirinde kristu yikirahure kuba kristu mu mwobo utemba, inzira yo kugaburira hamwe nuwagaburira.Moderate Al2O3 irashobora kunoza imbaraga za mashini hamwe nubumara bwimiterere yikirahure.
