What material is primarily used in the cloisonne technique to form walls?

The cloisonné technique primarily utilizes gold or other precious metal wires to create distinct walls that define the different colored sections of a design. This method involves soldering thin wires onto a metal base, typically copper or bronze, to form compartments or cells. These compartments are then filled with colored enamel, which is fired to create a vibrant, glass-like surface. The use of precious metal wires not only holds the enamel in place but also adds a luxurious quality to the finished piece, enhancing both its visual and aesthetic appeal. The precise arrangement of these metal walls is crucial, as it contributes to the overall structure and durability of the cloisonné work, while also defining the intricate patterns and designs that characterize this art form.
