Taupānga:
Ko nga pereki whakaraerae alumina teitei e whakamahia ana mo te masonry o nga kilns o roto o te ahumahi, penei i te pupuhi pupuhi, te wera wera wera, te oumu hiko, te reverberator, te hurihanga ciment kiln me etahi atu. I tua atu, ko nga pereki alumina teitei e whakamahia ana hei pereki kaitirotiro whakahou, te aukati i te punaha whakarewa tonu, pereki nozzle, etc.
