3. Ngā tukanga whakaputa mō ngā puranga pepa maitai momo-U

Ko te hanga o ngā puranga rau momo-U e whai ake ana i te hurihuri wera, i te hanga matao rānei:

Ngā Puranga Rau Momo-U Hurihia Wera

Tukanga:

(1). Rauemi mata: te pereki maitai kua whakamahanatia anō ki roto i te oumu (~1200 °C).
(2). Te hurihuri wera i roto i ngā rōra puranga pepa motuhake hei hanga i te kōtaha U.
(3). Te whakamatao, te whakatikatika, te tapahi ki ngā roa e hiahiatia ana.
(4). Te whakaoti me te tirotiro i ngā raka.
Ngā Āhuatanga:

He kaha ake, he piri ake ngā hononga.
He ātete wai pai ake.
Ka taea ngā wāhanga taumaha ake.
He mea noa i Ūropi, i Hapani, me Haina.

Ngā Puranga Rau Momo-U i Hangaia Matao

Tukanga:

(1). Ngā koiri maitai kua wetekina, kua whakatauritea.
(2). Te piko/te hanga matao mā te mīhini hanga hurihuri tonu i te pāmahana rūma.
(3). Te tapahi ki ngā roa e hiahiatia ana.
Ngā Āhuatanga:

He ohanga ake, he ngāwari ake te roa.
He whānui ake ngā kōwhiringa wāhanga.
Ngā hononga ā-pūngoi ake (kāore i te tino ātete ki te wai).
He mea noa ki Amerika Te Raki me Haina.
