Cloisonné is an ancient technique for decorating metalwork objects with colored material held in place or separated by metal strips or wire, normally of gold. In recent centuries, vitreous enamel has been used, but inlays of cut gemstones, glass and other materials were also used during older periods; indeed cloisonné enamel very probably began as an easier imitation of cloisonné work using gems. The resulting objects can also be called cloisonné. The decoration is formed by first adding compartments to the metal object by soldering or affixing silver or gold as wires or thin strips placed on their edges. These remain visible in the finished piece, separating the different compartments of the enamel or inlays, which are often of several colors. Cloisonné enamel objects are worked on with enamel powder made into a paste, which then needs to be fired in a kiln. If gemstones or colored glass are used, the pieces need to be cut or ground into the shape of each cloison.

Anglo-Saxon art covers art produced within the Anglo-Saxon period of English history, beginning with the Migration period style that the Anglo-Saxons brought with them from the continent in the 5th century, and ending in 1066 with the Norman Conquest of England, whose sophisticated art was influential in much of northern Europe. The two periods of outstanding achievement were the 7th and 8th centuries, with the metalwork and jewellery from Sutton Hoo and a series of magnificent illuminated manuscripts, and the final period after about 950, when there was a revival of English culture after the end of the Viking invasions. By the time of the Conquest the move to the Romanesque style is nearly complete. The important artistic centres, in so far as these can be established, were concentrated in the extremities of England, in Northumbria, especially in the early period, and Wessex and Kent near the south coast.
