Popis:	Precious Metals Clay which is a mixture of a precious metal powder and organic binders was doveloped. Two types clays were made by the binders of the different compositions. One resembled a paper clay and others resembled a chewing gum. Sintering process was investigated to make a gold of 18 carat from the Precious Metals Clay contained a mixed powder of 75%Au-12.5%Ag-12.5%Cu. The results showed that the two steps sintering process involving oxidation and reduction was suitable to sinter it. The sintered precious metals had enough strength to use as an ornament or a jewelery, although the mechanical properties were lower than the cast materials. Hollow beads could be made from the Precious Metals Clay using the Core Clay which was made of cellulose.
