Karāhe borosilicate teitei(e mōhiotia ana ko te karāhe mārō), e tohuhia ana e te whakamahinga o te karāhe hei kawe hiko i ngā pāmahana teitei. Ka rewa te karāhe mā te whakamahana i roto i te karāhe, ā, ka tukatukahia mā ngā tukanga whakaputa matatau.
Ko te tauwehenga ki te whakawhānui wera ko (3.3±0.1)x10-6/K, e mōhiotia ana ko te "karaehe borosilicate 3.3". He rauemi karaehe motuhake tēnei, he iti te tere whakawhanui, he ātete pāmahana teitei, he kaha teitei, he pakeke teitei, he mārama teitei
te whakawhiti me te pumau matū teitei. Nā tōna mahi tino pai, e whakamahia whānuitia ana i roto i te pūngao o te rā, te ahumahi matū, te takai rongoā, te puna rama hiko, ngā whakapaipai mahi toi me ētahi atu ahumahi.
