Abstract: Method of multi-color jewelry items production is based on a simultaneous casting of two metal alloys of different colors (yellow-red, white-yellow, etc.), as well as two different metals, with a purpose of obtaining jewelry art-works of high-quality and unique artistic impression. To serve that purpose, the following apparatus has been constructed: rubber base with two inlets, two-chamber ceramic crucible with two identical outlets, and a model of the jewelry item with two sprues connected to two separate tree stems, with each sprue connected to a separate stem thus ensuring flow of different colors or different metals. Simultaneous casting of two different metal alloys of different colors in two separate chambers of crucible is achieved by using a specially constructed two-head torch. Usage of this invention in the process of jewelry work casting ensures a unique natural effect of smooth transition from one color to another in a jewelry piece (ring, brooch, pendant, charm, etc.), reflecting high aesthetical criteria of jewelry accessories manufacturing at the world market.
