Kupu Whakataki

Karekare, kore-paitini. Te pirau i runga ake i te 1600 ℃. He wairewa i roto i te waikawa pungatara wera wera, kare e rewa i roto i te wai, waikawa waro me te waikawa pararopi, wairewa caustic, wairewa ki te waikawa pungatara wera me te waikawa pungatara wera wera. He pūmau ngā āhuatanga matū, ā, ka heke ki te barium sulfide mā te wera me te waro. E kore e huri te tae ina pa ana ki te hauwai sulfide, ki nga hau paitini ranei i te rangi.
