A Cambodian clay deposit was used for the development of tile formulations using the statistical design of mixture experiments. Besides the clays, commercial feldspar and silica sand (quartz) were also used to prepare ten different tile formulations. The specimens were fabricated by pressing (30 MPa) and then fired at 1170 oC. T e sintered specimens were characterized for their linear firing shrinkage, water absorption and modulus of rupture. Regression models were calculated, using mixture design experiments method, by relating the sintered properties with the compositions. The experimental results showed that Cambodian clays are suitable to be used as one a raw material in the production of ceramic tiles.
