PRODUCTION

Notes

Cloisonne is an ancient metalworking technique that was first developed in the Near East, before spreading to the Byzantine Empire and from there along the Silk Road to China. It is a multi-step enamel process used to produce jewellery, vases and other decorative items. The term cloisonne is derived from the French cloison, meaning compartment, because the decoration is applied to discrete areas that are separated by metal. The process of cloisonne starts with the artist forming the metal into the shape of the finished object, and then using a paper pattern and a pencil to transfer the design to the metal object. Partitions, which act as colour-separators, are then applied according to the transferred pattern and are held in place by a soldering paste. The partitions are bent and cut to length from flat wire stock (usually by hand, using pliers) and the paste is applied using a small brush. The metal piece is then heated in an oven. The solder melts, permanently fixing the partitions to the metal base. The object is then cooled. The artist paints frit (glass crushed to a powder) in a water-based paste into the partitions, guided by an annotated pattern. After the frit has dried, firing in an oven melts it onto the metal. Several repetitions of the process may ensue to build up the coatings to the height of the partitions. Various colours and transparencies may be used in combination within a single partition to obtain the desired artistic effect. Then the surface is ground and polished to make it even and smooth. Finally, the exposed metal is electroplated with a thin film of gold to prevent corrosion and to give a pleasing appearance.
