1. He pai te kawe wera o te takai i roto i te ngongo whakamahana whakarewa, ka taea te whakawhiti i te wera i hangaia e te waea whakamahana hiko ki te ringaringa tiaki i roto i te wā.
2. He rawaka te ārai me te kaha hiko o te whakakī i roto i te whakamahana whakarewa ngongo. E mōhio ana tātou katoa kāore i te āraihia te anga whakarewa me te waea whakamahana. Ka taea te whakamahi i te whakakī hei ārai i te āputa i waenga i te waea whakamahana me te anga ina kī tonu. Ina whakakahangia ngā whakamahana whakarewa, kāore te tinana ngongo e utua, ā, he pono te whakamahinga.
3. He tino ātete te takai i roto i te ngongo whakamahana whakarewa tio ki te wera, ā, he rite te tauwehenga whakawhanui ki tērā o te waea whakamahana, e whakawhāiti ana i te nekehanga o te waea whakamahana i te wā e hangaia ana te ngongo whakamahana kia whakawhāiti, kia whakamahana, kia piko hoki.
4. Kāore te rauemi whakakī i roto i te ngongo whakamahana whakarewa e pā ki te waea whakamahana hiko, ā, e kore e tauhohe ki te waea whakamahana hiko, ka pā ki ngā āhuatanga o te waea whakamahana hiko.
5. He tino pai te āhua o te mīhini o te whakamahana whakarewa me te rerekētanga o te pāmahana, ka taea te tiaki i te waea whakamahana hiko mai i te pēhanga me te pānga o waho; ka piki ohorere te pāmahana i roto i te wā poto, ā, kāore te pakitara o te ngongo e whānui, e pakaru rānei nā te nui rawa o te whānui. Hei tauira, ka piki te pāmahana o te paipa wera hiko pokepokea ki te 3~4℃ i roto i ētahi hēkona, i ētahi hēkona rānei i muri i te whakakā o te hiko.
6. He iti te hygroscope, ahakoa kua poke te hiri, e kore e mimiti te whakakī i te nui o te wai ina pa atu ki te hau i roto i te wā poto, ka puta he turuturu, nā te whānui wera me te whakaheke makariri rānei, ka mimiti te wai ki te hau, ka wera, ka whānui te hau, ka puta he pahūtanga.
7. He whānui te pūtake rauemi, ā, he iti te utu, ka whakaiti i te utu whakaputa me te whakamahi o te paipa wera hiko.
