The serious problem for pottery villages in Thailand, especially Dan Kwian village, is the falling prices of products due to oversupply. The aim of this work is to develop the properties of Dan Kwian cay for use in the production of ceramic tiles for which there is a big market. Feldspar and quartz were used to improve the firing properties of Dan Kwian clay. The compositions of the mixture were designed by a tri-axial diagram. The samples were formed by uniaxial dry press, and were sintered at 1200oC for 1 h. The results show that by adding a small amount of feldspar, i.e. 10 mass%, the firing properties of Dan Kwian clay are significantly improved and are useable for ceramic tiles.
