He kohuke kore-whakarewa tino nui te toka here. He maha ngā āhuatanga pai o te kaolin i hangaia mā te kuru, te huri me te whakapūkara, ā, kua whānuitia te whakamahinga i roto i ngā ahumahi maha, inā koa i roto i te ahumahi paninga. I tēnei wā, he iti te utu o ngā hua kaolin kua whakapūkarahia noa, engari kāore i te tino pai tōna kaha hipoki, ā, ka whakawhāitihia tōna whakamahinga i roto i te mara o ngā paninga kounga teitei. E whakaatuhia ana, me te piki haere o te rahi o te matūriki, ka piki haere te kaha hipoki o te kaolin kua whakapūkarahia, ko te take matua ko te mea he pai ake ngā matūriki kaolin, ka nui ake te kaha hipoki.Te huri kāolinhe taputapu whakaputa e whakamahia ana mō te tukatuka i te 300-1250 kaolin tino pai hei whakapai ake i tōna kaha hipoki. He aha ōna painga? Nā te kaihanga mira kaolin i tēnei rāGuilin Hongcheng he kupu whakataki taipitopito māu.

Whai muri i te kuru, te huri me te whakamahine nui, ka whakapūkarahia ki te 850℃, he tohutoro whaihua tēnei mō te whakamahinga me te tukatuka hohonu o te kaolin pūnaha waro. Nā te nui o te silicon me te konumohe, he pakarukaru te kaolin, ā, he uaua ki te mau. Me tino angiangi (325 mata tatari 5%~10%), ā, kāore e taea e te mira Raymond noa te whakatutuki i te hua teitei i runga i tēnei angiangi.
