Te karaihe borosilicate teitei(e mohiotia ana ko te karaehe pakeke), he tohu mo te whakamahi karaehe hei whakahaere i te hiko i te wera nui. Ka rewa te karaehe ma te whakamahana i roto o te karaehe ka tukatukahia e nga tikanga whakangao matatau.
Ko te whakarea ki te roha wera he (3.3±0.1)x10-6/K, e mohiotia ana ko "karaehe borosilicate 3.3". He taonga karaihe motuhake me te iti o te roha, te teitei o te pāmahana, te kaha nui, te pakeke, te marama teitei
te whakawhiti me te pumau matū nui. Na te pai o tana mahi, ka whakamahia nuitia i roto i te kaha o te ra, te umanga matū, te kapi rongoa, te puna rama hiko, nga taonga whakapaipai me etahi atu ahumahi.
