Characterization local clay ceramic in South Kalimantan  have been conducted in body system consisting of clays Nagara-Quartz-Feldspar with optimization using ternary triangle. The resulting ceramic body characterized by X-Ray Diffraction, and physical properties testing. The results showed that of the 15 compositions obtained six compositions that appropiate the SNI. with optimum combustion temperature 1100 o C. The optimum composition of ceramic body system Nagara clay 43.15%, 22.84% 34.01% quartz and feldspar with a total shrinkage of 8.71%, the modulus of 184.8 kg/cm 2 broken modulus and water absorption 12.21%.Key words: Nagara clay, ceramic body, shrinkage, broken modulus.
