No ka 'T’ helu helu, hoʻomanaʻo ʻia e kona ʻano helu: ʻoi aku ka nui o ka helu, ʻoi aku ka kiʻekiʻe a palekana ka helu.
No laila, ʻoi aku ka helu o ka BT4 ma mua o ka AT2.
He mea nui e hoʻomaopopo i ka 'T’ hōʻike i ka ʻili kiʻekiʻe mahana wela o na mea uila. He helu T4, kau i ka 135°C, pili no pahū nā kinoea me nā kiko uila ma mua o 135°C.
