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.Article10.1080/0371750X.2013.868322
