He tukanga nui te raina whakaputa rehu mō ngā pounamu karāhe hei whakarei ake i te āhua ataahua me te mahi o ngā takai waina. He maha ngā wāhanga o tēnei raina: he rūma rehu, he mekameka whakatārewatanga, me te oumu. Ko te whakarite i te kounga o te tukanga rehu me aro nui ki ngā āhuatanga maha, tae atu ki te maimoatanga wai me te ma o te mata o ngā pounamu karāhe. Kei raro nei ngā mahi e taunakitia ana mō te tukanga rehu whai hua:
1.Te Tukatuka Tuatahi
- Tatūnga Maimoatanga-muaKei roto i te wāhanga maimoatanga o mua ko ngā whakatikatika ki te tēpu tango matua. I ngā rohe makariri, he mea nui kia mau tonu te pāmahana i tēnei wāhanga kia pai ai te tukatuka. Tērā pea me whakamahi he whakamarumaru hei karo i ngā hua maimoatanga kāore i te tino pai.
2.Wā Whakamahana-Mua
- RoangaKo te tikanga, e 8 ki te 10 meneti te roa o tēnei wāhanga. Ko te kaupapa kia whiwhi te pounamu karāhe i te wera para i mua i te urunga ki te rūma paura. Mā tēnei wera ka pai ake te piri o te paninga paura.
3.Wāhanga Whakama
- Tango PuehuMena he tino pakari ngā whakaritenga kounga o te rauemi rehu, he mea nui te mahi purenga. Ko tēnei tukanga he pupuhi atu i te puehu me ngā matūriki mai i te rauemi hei ārai i te poke i te wā e rehu ana. He mea nui te mata ma hei whakatutuki i ngā hua kounga teitei.
4.Wāhanga Rehu Paura
- Tohungatanga HangarauKo te kounga o te rehu e whakawhirinaki ana ki te tikanga e whakamahia ana e te kaiwhakahaere. He mea nui ngā kaiwhakahaere mohio ki te whakatutuki i te paninga paura ōrite me te kounga teitei. Ko ngā pounamu karāhe tonu te whiringa matua i roto i ngā takai inu nā ō rātou āhuatanga ahurei e kore e taea e ētahi atu rauemi te taurite.
5.Wāhanga Whakamaroke
- Mana Pāmahana me te WāMe āta aroturuki te pāmahana me te roa o te wā whakamaroke. Ko te pāmahana tino pai kei waenganui i te 180 ki te 200 nekehanga Celsius, i runga i te rauemi o te mahi. He mea nui kia whakaitihia te tawhiti i waenga i te oumu whakamaroke me te rūma paura, kia 6 mita te tawhiti, kia pai ai te whakamaroke.
Whakamutunga
Mā te whakatinanatanga tika o ēnei mahi ka whakarite kia kounga teitei te rehu o ngā pounamu waina, kia mau tonu ai te ataahua me te pono o te mahi. Ko te aro nui ki ngā taipitopito i ia wāhanga o te tukanga, mai i te maimoatanga o mua ki te whakamaroke, he mea nui kia eke ki ngā hua pai rawa atu i te whakaotinga o ngā pounamu karāhe.
