TL;DR: The technique of cloisonne enamel, which can be traced back to the Mycenaean culture, flourished in Byzantium from the middle of the ninth century to 1204, with Constantinople at its centre as mentioned in this paper.
Abstract: The craft of enamelling originated in Europe.1 The technique of cloisonne enamel, which can be traced back to the Mycenaean culture, flourished in Byzantium from the middle of the ninth century to 1204, with Constantinople at its centre. Cloisonne was also crafted in the areas surrounding Constantinople (and continued after the extinction of the empire), in places such as Kiev, Georgia, Venice and Iran. The Celts had utilized the champleve enamel technique on copper long before Rome conquered Western Europe, and it is found in Romano-British decorative art. In twelfth-century Byzantium, champleve enamel superseded cloisonne and became one of the important means of expression in religious art. This champleve craft was popular in France, Spain and England up until the fourteenth century.2 The craft of painted enamel developed from cloisonne and champleve and originated from France, the Netherlands and Italy in the fifteenth century. Limoges in France is renowned for the high-quality production of this technique.
TL;DR: A mid fourteenth-century Spanish ciborium began to show signs of corrosion while on display in a closed case as discussed by the authors and was found to be associated with a certain color of enamel.
Abstract: A mid fourteenth-century Spanish ciborium began to show signs of corrosion while on display in a closed case. The ciborium is made of gilded copper and champleve enamel. The corrosion was found to be associated with a certain color of enamel. The enamel in the portions that evidence corrosion is itself much deteriorated. Though now a dull green-blue, it appears that it was once bright blue. Analysis shows that the deteriorated glass contains cobalt, which is probably the colorant. This enamel is a high potassium, low lead glass which is known to be unstable. Decomposition of this glass followed by leaching of components during a period of elevated relative humidity and temperature could account for the corrosion of the object. A fifteenth-century Spanish silver-gilt reliquary was found to have similarly deteriorated blue glass.
