Abstract

Several glazes with oxides as TiO2 , MoO, V2O5 and some rare elements are crystallizable in suitable technology of thermal. The crystals of these glazes shall create very fine decorating. The decorates will be enriched with coloured oxides such as Fe2O3, Cr2O3, MnO2, CoO ... To use crystallizable glazes in decorating ceramics firing at low temperature (850 - 1000°C) will produce new materials for handicraft ceramics of Vietnam . PbO can be either in compound of crystallizable glazes or not. This article is to recommend the glazes without Pbo being crystallizable in firing at 850 - 1000°C. The crystal phase is Willemite ( Zn2SiO4), TiO2 is playing the role of the minerallizer for it.
