Cloisonne Lapel Pins - are die struck from a copper bronze surface. A die is created to imprint your design into the metal. The outline of the pin and any cut-outs are then cut with another mold. Colors are hand-filled with a powdered glass-like mixture. Colors are fired one at a time at 1,600 F for two to four minutes. This two step process insures that bleeding of colors does not occur. Next, the pins are individually hand polished and then gold or silver plated.Then each pin is inspected to ensure only the highest quality is individually packaged and sent to us for final inspection.
