Te Hanga Ngongo Tuitui Kore-Tuitui Wera - Royal Group 

Hurihuri wera (whakaputainapaipa maitai kore-tuitui): te pire ngongo porowhita→whakamahana→wero→te hurihuri whakawhiti-toru, te hurihuri tonu, te whakaputanga rānei→te tango i ngā mea→te whakanui (te whakaiti rānei)→whakamatao→te whakatikatika→whakamātautau waipēhi (te kimi hapa rānei)→te tohu→rokiroki

Ko te rauemi mata mō te hurihuri i te paipa kore-ira he porowhita ngongo, ā, me tapahi te kukune ngongo porowhita mā te mīhini tapahi kia tupu ai ngā porowhita he 1 mita te roa, kātahi ka haria ki te oumu mā te whitiki kawe. Ka whāngaihia te porowhita ki roto i te oumu hei whakamahana, ko te pāmahana he 1200 nekehanga Celsius. Ko te wahie he hauwai, he acetylene rānei. Ko te whakahaere pāmahana i roto i te oumu he mea nui. Kia puta te ngongo porowhita i te oumu, me werohia mā te wero pēhanga.

Ko te tikanga, ko te mea werowero e tino kitea ana ko te werowero wira kōne. He pai te mahi whakaputa o tēnei momo werowero, he pai te kounga o te hua, he nui te whānui o te diameter o te poka, ā, ka taea te mau i ngā momo maitai rerekē. I muri i te werowero, ka tukuna te pire ngongo porowhita ki ngā takahuri whakawhiti e toru, te hurihuri tonu, te whakaputa rānei. I muri i te whakaputa, me tango te ngongo hei whakatakotoranga. Ka kerihia ngā kōhao ki roto i te pire mā te whakamahi i te kōne hurihuri tere-tere hei hanga ngongo. Ko te diameter o roto o te paipa maitai ka whakatauhia e te roa o te diameter o waho o te mata keri o te mīhini whakatakotoranga. I muri i te whakatakotoranga o te paipa maitai, ka tomo ki te pourewa whakamatao ka whakamatao mā te rehu wai. I muri i te whakamatao o te paipa maitai, ka whakatikatikaina.

I muri i te whakatikatika, ka tukuna te paipa maitai ki te taputapu kite hapa whakarewa (te whakamātautau waipēhi rānei) mā te whitiki kawe hei kimi hapa ā-roto. Mēnā he pakaru, he mirumiru me ētahi atu raruraru kei roto i te paipa maitai, ka kitea. Whai muri i te tirotiro kounga o ngā paipa maitai, me whiriwhiri ā-ringa tino tika. Whai muri i te tirotiro kounga o te paipa maitai, peitahia te tau rangatū, ngā whakatakotoranga, te tau puranga whakaputa, me ētahi atu ki te peita. Ā, ka hikitia ki roto i te whare putunga mā te kerēni.
