Ko te rerekētanga i waenganui ikarāhe whatume ētahi atu mōhiti, hei wāhanga o te pūnaha whatu, me tutuki i a ia ngā whakaritenga o te whakaahua whatu.
Mā te hangarau tukatuka makariri ka whakamahia te maimoatanga wera matū o te kohu me te wāhanga kotahi o te karāhe silica houra-raima hei whakarerekē i tōna hanganga ngota taketake, me te kore e pā ki te tae taketake me te whakawhiti mārama o te karāhe, kia eke ai ki te paerewa tino pakeke, me te whakatutuki i ngā whakaritenga tiaki ahi i raro i te pānga mura pāmahana teitei. Ko te karāhe ātete ahi tino pakeke me tana tikanga hanga me ngā taputapu motuhake. He mea hanga mai i ngā wāhanga ōwehenga taumaha e whai ake nei: kohu tote pāhare pāporo (72%～83%), te hauhā (7%～10%), te hau konupora hau (8%～12%), te hauota (2%～6%).
Ko ngā whakaritenga mō te kounga o te karāhe whatu e whai ake nei:
1. Ngā pūmau whatu motuhake me te ōritetanga o ngā pūmau whatu o te puranga karāhe kotahi
He uara taupū whakaata paerewa kua whakaritea mō ia momo karāhe whatu mō ngā roangaru mārama rerekē, ā, koinei te pūtake mō ngā kaihoahoa whatu ki te hoahoa i ngā pūnaha whatu. Me noho ngā pūmau whatu o ngā karāhe whatu katoa i hangaia i te wheketere ki roto i tētahi awhe e whakaaetia ana o ēnei uara, ki te kore, kāore te kounga whakaahua tuturu e ōrite ki te hua e tumanakohia ana i te wā hoahoa, ā, ka pāngia te kounga o te taputapu whatu.
2. Te Māramatanga Nui
He rite te kanapa o te ahua o te pūnaha whatu ki te mārama o te karāhe. Ko te mārama o te karāhe whatu ki te mārama o tētahi roangaru ka whakaatuhia e te tauwehenga mimiti mārama Kλ. I muri i te whitinga o te mārama i roto i tētahi raupapa o ngā porotiti me ngā karāhe arotahi, ka ngaro tētahi wāhanga o tōna kaha e te whakaata atanga o ngā wāhanga whatu, ā, ka mimitihia tētahi wāhanga e te reo (karāhe) tonu. Ka piki ake te mea tuatahi me te pikinga o te taupū whakaata o te karāhe. Mō te karāhe taupū whakaata teitei, he tino nui tēnei uara. Hei tauira, ko te ngaronga whakaata mārama o tētahi mata o te karāhe kiripaka taumaha he tata ki te 6%. Nō reira, mō tētahi pūnaha whatu kei roto he maha ngā karāhe angiangi, ko te huarahi matua ki te whakanui ake i te tuku ko te whakaiti i te ngaronga whakaata o te mata karāhe arotahi, pērā i te paninga i te mata ki tētahi paninga ārai-whakaata. Mō ngā wāhanga whatu nui pērā i te karāhe arotahi o tētahi karu tiro whetū, ko te tuku o te pūnaha whatu ka whakatauhia e te tauwehenga mimiti mārama o te karāhe tonu nā tōna matotoru nui. Mā te whakapai ake i te parakore o ngā rauemi mata o te karāhe, me te ārai i te ranunga o ngā poke tae i roto i te tukanga katoa mai i te puranga ki te whakarewa, ko te tauwehenga mimiti mārama o te karāhe ka iti iho i te 0.01 (arā, ko te tuku mārama o te karāhe he 1 cm te matotoru he nui ake i te 99%).
