Abstract

The most important point of whitening frit glazes is the elimination of transperancy. For that purpose, opacifiers are used. In this work, the effect of Ag2O additive on colour variation and gloss of a white opaque glaze, used commonly in ceramic ware production, were investigated at the temperatures of 1040°, 1090° and 1140°C. It was found that colour and gloss of an opaque glaze did not vary significantly with Ag2O addition. Furthermore, Ag2O addition was found to be a viable alternative for reducing the sintering temperature of opaque glaze from 1090° to 1040°C. © 2014 © 2014 The Indian Ceramic Society.
