I hangaia te karāhe ārai i te tau 1865. He rauemi hanga te karāhe ārai he pai te ārai wera, he pai te ārai oro, he ataahua, he whai hua hoki, ā, ka taea te whakaiti i te taumaha o te whare. He mea hanga mai i te karāhe ārai oro tino whai hua o ngā karāhe e rua (e toru rānei) mā te whakamahi i te piri hiato kaha me te matotoru hau hei hono i te karāhe ki te anga whakamaroke konumohe kei roto.
Hiri rua-awa konumohe
Ka wehea te mokowā konumohe mai i ngā wahi karāhe e rua kia ōrite, ka whakakīia te mokowā konumohe ki te tātari karāhe (matūriki) whakamaroke, hei hanga i te wāhi hiri i waenganui i ngā paparanga karāhe.
Ka taea e te tātari ngota karāhe whakamātao te mimiti i te wai me ngā poke matū toenga i roto, ka pupuri i te karāhe whakamātao kia ma, kia mārama ahakoa te pāmahana tino iti, ā, ka taea hoki e ia te whakataurite i te rerekētanga kaha o te pēhanga o roto me waho i puta mai i ngā huringa nui o te pāmahana. Ka whakatauhia hoki e te tātari ngota karāhe whakamātao te raruraru o te whakapōturi me te kuru i puta mai i te whānui, te whakaheke rānei o te karāhe, ā, ka roa ake te ora o te karāhe whakamātao.
Te whakamahinga o te tātari ngota karāhe ārai:
1) te mahi whakamaroke: te mimiti i te wai mai i te karāhe tuwhera.
2) Pānga ārai huka.
3) Horoi: mimitia te puehu e mānu ana i te rangi.
4) taiao: ka taea te hangarua, kāore he kino ki te taiao
Hiri momo-rīpene piripiri whakakotahi
Ko te rīpene hiri ārai he kohinga o ngā mahi whakawātea me te tautoko o te anga konumohe, te mahi whakamaroke o te tātari ngota karāhe ārai (paura), te mahi hiri o te kāpia butyl, me te mahi kaha hanganga o te kāpia polysulfide, ka taea te piko i te rīpene hiri karāhe ārai ki tetahi āhua ka tāuta ki runga i te karāhe.
