The investigation was carried out to incorporate newly tapped Rajpardi clay, an overburden material of a lignite mine on replacements of extensively used traditional plastic clays like Than and Bikaner in the earthenware type glazed wall tile body composition. Test specimens of five different body compositions incorporating Rajpardi clay were prepared and fired at four different test temperatures, viz. 950°, 1050°, 1100° and 1150°C in an electrical furnace. Dry and fired properties like dry shrinkage, dry MOR, fired shrinkage, fired MOR, percent apparent porosity, percent water absorption, bulk density etc were determined and compared with those of the specimens of a traditional earthenware tile body used as a standard composition. It was observed that the incorporation of Rajpardi clay in the tune of 25 wt% was the optimum condition in achieving the requisite thermo-mechanical properties in wall tile body. A significant increase in the values of dry and fired MOR, as compared to those of the standard composition, was also noticed.
