ABSTRACT:
A ribbon of color A metal is combined with a thin layer of soldering alloy, bent and soldered to form a tube, it is then filled with a core of color B metal. The compound is then drawn and/or laminated until it is transformed into a long ribbon or into a wire, externally of color A and internally of color B. The filled ribbon or wire is wrapped like a solenoid around a deformable support, like a metal mesh and stamped into the desired shape. The resulting two faced element is then ground in order to remove, all along a strip and following a line or in dots, the superficial part of color A until the core of color B is revealed. The bi-colored long element is then treated like a single body and allows the realization of precious bi-colored ornamental items.
