Cloisonné pins continue the fine-art tradition of glass enameling started in China centuries ago. The pins are made by hand-pouring powdered glass into the recesses of a die struck brass base. The brass can be plated in gold, silver, nickel, black nickel or bronze. After being baked at a very high temperature, the glass enamel is sanded and polished to be flush with the metal lines that separate the colors. This gives the pins a smooth and lustrous quality. Colors are limited with this technique.
