He mea nui te whiriwhiri i te pounamu tika i te wā e penapena ana, e whakamahi ana hoki i ngā hinu kakara. He tino kukū ngā tangohanga tipu o ngā hinu kakara, ā, ki te kore e penapena tika, ka ngoikore pea tōna kaha me tōna whai huatanga. Ka taea e te pounamu tika te tiaki i te hinu kakara mai i ngā pānga o te rā, te wera me te hau, kia mau tonu ai ōna āhuatanga mō te wā roa.
Ko tētahi o ngā momo rongonui ongā pounamu hinu kakarako te pounamu karāhe. He rauemi pai te karāhe mō te penapena hinu kakara nā te mea kāore e uru ki te hau me te makuku. He maha ngā wā ka whakamahia ngā pounamu karāhe amber, kikorangi kobalt rānei, nā te mea he parenga atu ēnei mai i te hihi UV, ka taea te whakaheke i te kounga o te hinu kakara. Ka āwhina te karāhe pouri ki te aukati i ngā hihi kino, ka ārai i ngā hinu mai i te kino me te pirau. Kāore hoki ngā pounamu karāhe e tauhohe ki ngā hinu, ka ārai i ngā taunekeneke matū kāore e hiahiatia ki ētahi rauemi kirihou.
Ko tētahi atu whakaaro nui i te wā e whiriwhiri ana i tētahipounamu hinu kakarako te momo taupoki, te momo taupoki rānei. He mea nui te taupoki piripono hei pupuri i te hou me te kaha o tō hinu. He mea whakamahi noa ngā taupoki maturuturu nā te mea ka taea te tohatoha ngāwari me te tika o te hinu. Ko ēnei taupoki he mea hanga ki te karāhe, ki te kirihou rānei, engari he mea nui kia whakarite kia hangaia ki ngā rauemi e hototahi ana ki ngā hinu kakara kia kore ai e pirau, e poke rānei.
Haunga ngā pounamu karāhe, he pai anō hoki ki ētahi te whakamahi i ngā pounamu kowiri tira hei pupuri i ngā hinu kakara. He tino pakari te kowiri tira, ā, he ātete ki te pakaru, he mea pai tēnei mō te hunga e haereere tonu ana, e hiahia ana rānei ki te kawe i ā rātou hinu. Ka tiaki anō hoki ngā pounamu kowiri tira i te hihi UV, ā, kāore e tauhohe ki ngā hinu. Heoi, he mea tika kia mōhiotia kāore pea ngā pounamu kowiri tira e pai mō te rokiroki mō te wā roa, nā te mea ka taea tonu e rātou te uru atu ki te hau me te makuku i roto i te wā.
Hei tāpiri, i te wā e whiriwhiri ana koe i tētahi pounamu mō ō hinu kakara, me whakaaro koe ki te rahi o te pounamu. He pai ake ngā pounamu iti ake nā te mea ka āwhina i te whakaiti i te pānga ki te hau me te makuku, ā, ka mau tonu te kounga o te hinu. He mea pai kia hoko i tētahi hinu kakara iti ka whakawhiti ki tētahi pounamu iti ake hei whakamahi, me te whakarite kia kaua te nuinga o te hinu e pāngia e te hau, e te mārama rānei kia hiahiatia rā anō.
Hei whakarāpopototanga, ko te mea pai rawa atungā pounamu hinu kakarahe pounamu karāhe pouri me te taupoki piri (pērā i te taupoki maturuturu). He tino pai te tiaki a ngā pounamu karāhe mai i te hau, te mārama me te makuku, ā, ka āwhina te tae pouri ki te aukati i ngā hihi UV kino. He pai hoki ngā pounamu kowiri tira mō te whakamahi i a koe e haereere ana, engari kāore pea e pai mō te rokiroki mō te wā roa. Kia mahara ki te whiriwhiri i ngā pounamu iti ake hei whakaiti i te pānga ki te hau me te mārama. Mā te whiriwhiri i te pounamu tika mō ō hinu kakara, ka taea e koe te whakarite kia roa ake te kaha.
