Ko te hanganga matū o ngā pirepire e mānu ana ko te hauhā silicon me te waikura konumohe. He maha ngā āhuatanga pēnei i te matūriki angiangi, te takoto kau, te mama, te kaha teitei, te ātete ki te kakahu, te ātete ki te pāmahana teitei, te whakamarumaru wera me te ātete mura. He whānuitia te whakamahinga i roto i tētahi o ngā rauemi mata mō te umanga ātete ahi.

He aha ngā porowhita iti uku?

Ko ngā porowhita iti uku tuwhera he porowhita iti uku tuwhera e kitea ana i roto i te pungarehu rere, he hua taiao o te tahunga waro i te wā e whakaputahia ana te hiko.

Ko te ātete o ngā porowhita iti uku he 1610 nekehanga Celsius, he rauemi ātete wera mama pai rawa atu.

Nā te iti, te māmā, te tuwhera, me te kaha nui, ka whakamahia whānuitia ngā Maikoro Porowhita Kohao Uku hei whakakī, hei whakaroa mahi rānei i roto i te hanga kirihou, peita, kapia me ētahi atu.

Ka whakaratohia hoki e ngā Cenospheres te painga o te rere me te ngāwari o te mahi, he mea e hiahiatia ana i roto i ngā momo tono maha, pēnei i te: Te sima hinu, te raima korehau.

Ka whakaratohia hoki e ngā Cenospheres te painga o te rere me te ngāwari o te mahi, he mea e hiahiatia ana i roto i ngā momo tono maha, pērā i: Te Whakapūtanga Sima mō te Puna Hinu, Ngā Whare Whakakā me ngā Whare Hanganga, Ngā Hua Hanganga Sima, Ngā Matū Hononga, Te Whakaiti Oro o te Uku, Ngā Piripiri, me te maha atu.
