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

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