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 ngwá ọrụ ịkpụzi, karama biya, karama mmanya, mkpọ nwere ike iji ụdị ihe a mee ihe, dị nnọọ 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%.
