The effect of albite wastes on glaze properties and microstructure of softporcelain zinc crystal glazes

The efficient utilisation of waste materials arising from diverse industria l branches is of technological importance. As a replacement material for fe ldspar in some soft porcelain zinc crystal glazes, albite triage wastes whi ch contain high levels of titania have been investigated. It has been seen that this material decreases glaze maturing temperature and that during slo w cooling it promotes crystallisation resulting in very attractive natural crystal growth. These positive effects suggest that albite triage wastes ca n easily be used in zinc crystal glazes as an alternative to feldspar. By d oing so, glaze cost will be decreased and a waste material will be effectiv ely utilised. (C) 2001 Elsevier Science Ltd. All rights reserved.
