Ko te tōngāmimi o te pounamu wai whakawetohia he mea hanga ki te karaehe papa-rua.Ko nga paparanga karaihe e rua kua whakakikoruatia ki te hiriwa, ano he whakaata, ka taea te whakaata i nga hihi wera ki muri ka tapahia te ara o te iraruke wera.
Ko te korehau i waenganui i nga paparanga e rua o te karaihe i roto i te werawera ka whakangaro i nga tikanga o te kawe convection.Ko te whakamahi i te taupoki pounamu wai tiaki wera e kore e ngawari ki te whakawhiti wera ka tapahia te huarahi o te whakawhiti me te whakawhiti wera.
