PURPOSE: To produce a material to be worked capable of obtaining a metallic product rich in uniqueness and having designability by kneading a metal powder and an aq. soln. of org. binder to obtain a clayey kneaded product, by forming the product into an optional shape by calcining the kneaded product an a specified temp.
CONSTITUTION: A pure metal powder (Fe, Cu, Au, Ag, Pt, etc.) or a metal powder (having 5-100μm average grain diameter) consisting of one or more kinds of the alloy powder materials consisting essentially of the elements and an aq. soln. (about 5-6% concn.) of org. binder (methylcellulose, etc.) are kneaded to produce a clayey kneaded product, the product is formed into an optional shape, and the neaded product is calcined at 50-450°C for 5-40min to obtain a stably formed material to be worked. The material is carved in a desired manner and sintered at a specified temp. to extremely easily obtain a metallic product rich in decorativeness.
