Te mahi a te strontium carbonate i roto i te glaze: ko te frit te whakarewa i te rauemi mata, te huri rānei hei tinana karāhe, he rauemi mata rere e whakamahia whānuitia ana mō te glaze uku. Ina whakarewahia kia rere, ka taea te tango i te nuinga o te hau mai i te rauemi mata glaze, ā, ka whakaitihia te whakaputanga o ngā mirumiru me ngā kōhao iti i runga i te mata o te glaze uku. He mea nui rawa atu tēnei mō ngā hua uku he teitei te pāmahana tahu me te poto te huringa tahu, pērā i ngā uku o ia rā me ngā uku parakore.
I tēnei wā, e whakamahia whānuitia ana ngā paraihe i roto i ngā paninga uku tere-tahu. Nā te iti o te pāmahana rewa tuatahi me te whānuitanga pāmahana wera nui, he mea nui te mahi a te paraihe i roto i te whakarite i ngā hua uku hoahoa tere-tahu. Mō te porcelain he teitei ake te pāmahana wera, ko te rauemi mata tonu te paninga matua. Ahakoa ka whakamahia te paraihe mō te paninga, he iti noa te nui o te paraihe (he iti iho i te 30% te nui o te paraihe i roto i te paninga).
Ko te kiriuhi frit kore-mata he mea hanga ki te mara hangarau o te kiriuhi frit mō ngā uku. He mea hanga mai i ēnei rauemi mata e whai ake nei mā te taumaha: 15-30% o te quartz, 30-50% o te feldspar, 7-15% o te borax, 5-15% o te waikawa boric, 3-6% o te barium carbonate, 6-6% o te stalactite. 12%, te zinc oxide 3-6%, te strontium carbonate 2-5%, te lithium carbonate 2-4%, te slaked talc 2-4%, te konumohe hydroxide 2-8%. Mā te kore rewa o te mata ka taea te whakatutuki i ngā hiahia o te tangata mō ngā uku hauora me te kounga teitei.
