The market of silver precious metal clay (PMC) is promising as its application for agile metal craft. The property of suitable hardness and shrinkage as well as environment-safe is strictly required as people make the final product with bare hands. We propose a silver PMC with new organic binder made of palm oil, glycolic acid and water. Then we prepared disk specimen of our proposed PMC and well-known commercial PMC. We investigated the hardness, weight change, linear shrinkage, density and micro structure evolution with sintering temperature of $700{\sim}900^{\circ}C$ ($50^{\circ}C$ gap) for 15minutes. We confirm our proposed PMC has suitable property for craft product comparable for commercial PMC, and the optimum sintering condition is $850^{\circ}C$-15minutes for metal craft application.
