Champlevé in the context of "Jewellery chain"

Limoges enamel has been produced at Limoges, in south-western France, over several centuries up to the present. There are two periods when it was of European importance. From the 12th century to 1370 there was a large industry producing metal objects decorated in enamel using the champlevé technique, of which most of the survivals (estimated at around 7,500 pieces), and probably most of the original production, are religious objects such as reliquaries.

After a gap of a century, the industry revived in the late 15th century, now specializing in the technique of painted enamel, and within a few decades making rather more secular than religious pieces. In the French Renaissance it was the leading centre, with several dynastic workshops, who often signed or punchmarked their work. Luxury pieces such as plates, plaques and ewers were painted with sophisticated Mannerist decoration of pictorial figure scenes, which on vessels were surrounded by elaborate borders.

Ronde-bosse, en ronde bosse or encrusted enamel is an enamelling technique developed in France in the late 14th century that produces small three-dimensional figures, or reliefs, largely or entirely covered in enamel. The new method involved the partial concealment of the underlying gold, or sometimes silver, from which the figure was formed. It differs from older techniques which all produced only enamel on a flat or curved surface, and mostly, like champlevé, normally used non-precious metals, such as copper, which were gilded to look like gold. In the technique of enamel en ronde-bosse small figures are created in gold or silver and their surfaces lightly roughened to provide a key for the enamel, which is applied as a paste and fired. In places the framework may only be wire.

The term derives from the French term émail en ronde bosse ("enamel in the round"); however in French en ronde bosse merely means "in the round" and is used of any sculpture; in English ronde bosse or en ronde bosse, though usually treated as foreign terms and italicised, are specifically used of the enamel technique, and in recent decades have largely replaced the older English term "encrusted enamel".

The Cross with large enamels, or Senkschmelz Cross, known in German as the Senkschmelzen-Kreuz or the Kreuz mit den großen Senkschmelzen (Cross with large senkschmelz enamels), is a processional cross in the Essen Cathedral Treasury which was created under Mathilde, Abbess of Essen. The name refers to its principal decorations, five unusually large enamel plaques made using the senkschmelz technique, a form of cloisonné which looks forward to champlevé enamel, with a recessed area in enamel surrounded by a plain gold background, and distinguishes it from three other crosses of the crux gemmata type at Essen. The cross is considered one of the masterpieces of Ottonian goldsmithing.
