AbstractClay deposits from Turgutlu provide raw materials for the brick-tile production. This clay has been mined since 1980. Before 1980, clays from the agricultural area were used as construction materials. It is well possible that they have also been used for producing pottery during ancient times at Sardes. This study investigates the chemical and mineralogical characteristics of the Turgutlu brick-tile raw materials and their properties after firing between 600 and 1050 ºC. The mineralogical and physical changes of mixtures with addition of 5 and 12% Turgutlu raw material to the receipt of floor-tiles body was studied. The use of this raw material results in smaller consumption of clays for the production of ceramic body receipts, and hence provides significant economics for the producer.
