Dabere na sistemụ ternary SiO 2-CAO -Na2O, a na-agbakwunye ihe ndị mejupụtara iko iko sodium na calcium na Al2O 3 na MgO. Ihe dị iche bụ na ọdịnaya nke Al2O 3 na CaO na iko karama dị oke elu, ebe ọdịnaya MgO dị ntakịrị. N'agbanyeghị ụdị ihe eji akpụzi, karama biya, karama mmanya, karama nwere ike iji ụdị ihe a, dị ka ọnọdụ dị adị na-eme ka ọ dị mma.
Ihe mejupụtara ya (nkebi uka) sitere na SiO 27% ruo 73%, A12O 32% ruo 5%, CaO 7.5% ruo 9.5%, MgO 1.5% ruo 3%, na R2O 13.5% ruo 14.5%. A na-eji ụdị ihe mejupụtara a mara mma nke aluminom na-agafeghị oke ma enwere ike iji ya chekwaa ọnụ ahịa site na iji ájá silica nwere Al2O3 ma ọ bụ iji feldspar webata alkali metal oxides. CaO+MgO nwere oke olu yana ọsọ ike siri ike.
Iji mee mgbanwe maka ọsọ igwe dị elu, a na-eji akụkụ nke MgO kama CaO iji gbochie kristal kristal ka ọ bụrụ crystallized na oghere mgbaba, ụzọ nri na onye na-enye nri. Al2O3 na-agafeghị oke nwere ike melite ike igwe na nkwụsi ike nke iko.
