The disclosure relates to an art medium which is readily moldable, has substantially the same feel as clay, can provide aesthetic exterior surfaces without additional processing steps, can be worked by standard metal working tools, such as drills, etc. and results in a metal end product. Briefly, the above is accomplished by homogeneously mixing together a powdered metal which is sinterable and a plasticizer. This composition is mixed together with a liquid, preferably water in sufficient quantity to provide the consistency desired by the user, the same as when operating with clay. Water is added during molding to replace that which evaporates to maintain the desired consistency. The powdered metal has an average particle size of form about 10 microns down to about 0.1 micron. The ratio by weight of powdered metal to plasticizer is from about 97% to about 91% powdered metal and from about 3% to about 9% plasticizer. A preferred ratio by weight is 95% powdered metal and 5% plasticizer. Any metal or combination of metals or prealloys which are available ion powdered from and are sinterable can be used. Nickel is a preferred metal due to the glossy non-rusting surface that can be obtained after sintering. A preferred plasticizer with water is bentonite. From about 5% to about 20% by weight of metal particles having diameter substantially larger than the powdered metal by at least about ten times can be used in place of some of the powdered metal to aid in binder extraction.
