The aimof this study was to examine the effect of sago binder concentration on the physical characteristics of porous ceramics, in the form of mass shrinkage and density. Porous ceramics were synthesized using the gelcasting method with raw materialof South Sulawesi natural clay, sago binderas pore template , and dispersantof CMC. The ceramics produced are ceramics with a low of toxicity so that itsenvironmentally friendly. The research stages consisted of preparation of natural clay from South Sulawesi, synthesis of porous ceramics by gelcasting with a variationof binder concentration2%; 4%; 6%; 8%; 10%, measuring the mass shrinkage and measuring the density of porous ceramic. The results showed the greater binder concentration, the greater massshrinkage obtained, the largest mass shrinkage occurred at a 10% binder concentration of 26.87%. The density of ceramics decreases with increasing binder concentration, the lowest density occurs at 10% binder concentration of 1,6403g/cm3.
