Abstract
In a normal stoneware ceramic composition, feldspar was partially substituted by two types of soda lime silica scrap glass powder (fl int-chromium free and opaque-chromium doped). Samples were fi red in the temperature range of 1100–1250 °C and their physico-mechanical properties were studied and compared with the normal composition. Samples containing fl int glass powder achieved early vitrifi cation at 1200 °C compared to 1250 °C for opaque glass containing sample as well as normal stoneware body. Both bodies achieved more than 40 MPa fl exural strength at their vitrifi cation temperature. Formation of needle shaped mullite crystals was observed in all samples. Presence of large number of smaller size mullite crystals was responsible for strength development
