I runga i te punaha SiO 2-CAO -Na2O ternary, ko te konutai me te konupūmā nga kai karaihe pounamu ka whakauruhia ki te Al2O 3 me te MgO. Ko te rereketanga ko te ihirangi o te Al2O 3 me te CaO i roto i te karaihe pounamu he tino tiketike, engari he iti te ihirangi o MgO. Ahakoa he aha te momo taputapu hanga, ipu pia, ipu waipiro, kene ka taea te whakamahi i enei momo kai, kia rite ki te ahuatanga o te mahi ki te mahi pai.
Ko ona wahanga (hautanga papatipu) mai i te SiO 27% ki te 73%, A12O 32% ki te 5%, CaO 7.5% ki te 9.5%, MgO 1.5% ki te 3%, me te R2O 13.5% ki te 14.5%. Ko te ahua o tenei momo hanganga ko te ahua o te ihirangi konumohe ngawari, ka taea te whakamahi ki te penapena utu ma te whakamahi i te kirikiri kirikiri kei roto Al2O3 te whakamahi ranei i te feldspar hei whakauru i nga waikura whakarewa alkali. CaO+MgO he rōrahi teitei me te tere whakapakeke.
Hei urutau ki te tere miihini teitei ake, ka whakamahia tetahi waahanga o te MgO hei utu mo te CaO hei aukati i te karaehe karaihe kia kore e maataata i roto i te kohao rere, te ara whangai me te kai whangai. Ka taea e Al2O3 te whakapai ake i te kaha miihini me te pumau matū o te karaihe.
