Ancient world Cloisonné first developed in the jewellery of the
ancient Near East, and the earliest works with enamel all used the cloisonné technique, placing the enamel within small cells with gold walls. This had been used as a technique to hold pieces of stone and gems tightly in place since the 3rd millennium BC, for example in
Mesopotamia, and later in
Egypt. Enamel seems likely to have developed as a cheaper method of achieving similar results. The earliest surviving undisputed objects known to use enamel are a group of
Mycenaean rings from a tomb in
Cyprus, dated to the 12th century BC, which used very thin wire. In the
jewellery of ancient Egypt, including the
pectoral jewels of the
pharaohs, thicker strips form the cloisons, which remain small. In Egypt gemstones and enamel-like materials (sometimes called "glass-paste") were both used. Although Egyptian pieces, including jewellery from the
Tomb of Tutankhamun of , are frequently described as using "enamel", many scholars doubt that the glass paste was sufficiently melted to be properly so described, and use terms such as "glass-paste". It seems possible that in Egyptian conditions the melting point of the glass and gold were too close to make enamel a viable technique. Nonetheless, there appear to be a few actual examples of enamel, perhaps from the
Third Intermediate Period of Egypt (beginning 1070 BC) on. But it remained rare in both Egypt and Greece. The technique appears in the
Koban culture ( to 350 BC) of the northern and central
Caucasus, and was perhaps carried by the
Sarmatians to the ancient
Celts, but they essentially used the champlevé technique. Subsequently, enamel was just one of the fillings used for the small, thick-walled cloisons of the
Late Antique and
Migration Period styles. At
Sutton Hoo, the
Anglo-Saxon pieces (dated to the 6th or 7th centuries AD) mostly use garnet cloisonné, but this is sometimes combined with enamel in the same piece. A problem that adds to the uncertainty over early enamel is artefacts (typically excavated) which appear to have been prepared for enamel, but which have now lost whatever filled the cloisons. This occurs in several different regions, from ancient Egypt to Anglo-Saxon England. Once enamel becomes more common, as in medieval Europe after about 1000, the assumption that enamel was originally used becomes safer.
Byzantium and Europe The Byzantines perfected a unique form of cloisonné
icons.
Byzantine enamel spread to surrounding cultures and a particular type, often known as "garnet cloisonné" is widely found in the
Migration Period art of the "
barbarian" peoples of Europe, who used gemstones, especially red
garnets, as well as glass and enamel, with small thick-walled cloisons. Red garnets and gold made an attractive contrast of colours, and for Christians the garnet was a symbol of
Christ. This type is now thought to have originated in the
Late Antique Eastern Roman Empire and to have initially reached the Migration peoples as diplomatic gifts of objects probably made in
Constantinople, then copied by their own goldsmiths. Glass-paste
cloisonné was made in the same periods with similar results – compare the gold
Anglo-Saxon fitting with garnets (right) and the
Visigothic brooch with glass-paste in the gallery. Thick ribbons of gold were soldered to the base of the sunken area to be decorated to make the compartments, before adding the stones or paste. In the Byzantine world the technique was developed into the thin-wire style suitable only for enamel described below, which was imitated in Europe from about the
Carolingian period onwards. in
Vollschmelz cloisonné enamel on gold The dazzling technique of the
Anglo-Saxon dress fittings from
Sutton Hoo include much garnet cloisonné, some using remarkably thin slices, enabling the patterned gold beneath to be seen. There is also imported
millefiori glass cut to fit like the gems. Sometimes compartments filled with the different materials of cut stones or glass and enamel are mixed to ornament the same object, as in the
Sutton Hoo purse-lid. From about the 8th century,
Byzantine art began again to use much thinner wire more freely to allow much more complex designs to be used, with larger and less geometric compartments, which was only possible using enamel. These were still on relatively small objects, although numbers of plaques could be set into larger objects, such as the
Pala d'Oro, the
altarpiece in
Saint Mark's Cathedral,
Venice. Some objects combined thick and thin cloisons for varied effect. The designs often (as at right) contained a generous
background of plain gold, as in contemporary
Byzantine mosaics. The area to be enamelled was stamped to create the main depression, pricked to help the enamel adhere, and the cloisons added. Two different techniques in Byzantine and European cloisonné enamel are distinguished, for which the German names are still typically used in English. The earliest is the
Vollschmelz ("full" enamel, literally "full melt") technique where the whole of a gold base plate is to be covered in enamel. The edges of the plate are turned up to form a reservoir, and gold wires are soldered in place to form the
cloisons. The enamel design therefore covers the whole plate. In the
Senkschmelz ("sunk" enamel, literally "sunk melt") technique the parts of the base plate to hold the design are hammered down, leaving a surrounding gold background, as also seen in contemporary Byzantine icons and mosaics with
gold glass backgrounds, and the saint illustrated here. The wires and enamels are then added as before. The outline of the design will be apparent on the reverse of the base plate. The transition between the two techniques occurs around 900 in Byzantine enamel, and 1000 in the West, though with important earlier examples. The plaques with apostles of around the latter date on the
Holy Crown of Hungary show a unique transitional phase, where the base plaque has hammered recesses for the design, as in
senkschmelz work, but the enamel covers the whole plaque except for thick outlines around the figures and inscriptions, as in the
vollschmelz technique (see the gallery below for examples of this technique and
vollschmelz work). Some 10th-century pieces achieve a
senkschmelz effect by using two plates superimposed on each other, the upper one with the design outline cut out and the lower one left plain. backed onto glass or
rock crystal In medieval Western Europe cloisonné enamel technique was gradually overtaken by the rise of
champlevé enamel, where the spaces for the enamel to fill are created by making recesses (using various methods) into the base object, rather than building up compartments from it, as in cloisonné. This happened during the 11th century in most centres in Western Europe, though not in Byzantium; the
Stavelot Triptych,
Mosan art of around 1156, contains both types, but the inner cloisonné sections were probably gifts from
Constantinople. Champlevé allowed increased expressiveness, especially in human figures, and was also cheaper, as the metal base was usually just
copper and if gold was used, it was generally to
gild surrounding bare metal. In turn champlevé was replaced by the 14th or 15th century by painted enamels, once techniques were evolved that allowed the enamel to be painted onto a flat background without running.
Limoges enamel was a great centre for both types.
Plique-à-jour is a related enameling technique which uses clear enamels and no metal backplate, producing an object that has the appearance of a miniature stained glass object - in effect cloisonné with no backing. Plique-a'-jour is usually created on a base of mica or thin copper which is subsequently peeled off (mica) or etched away with acid (copper). In the Renaissance the extravagant style of pieces effectively of plique-à-jour backed onto glass or
rock crystal was developed, but was never very common. Other ways of using the technique have been developed, but are of minor importance. In 19th century Japan it was used on
pottery vessels with ceramic glazes, and it has been used with
lacquer and modern
acrylic fillings for the cloisons. A version of cloisonné technique is often used for lapel badges, logo badges for many objects such as cars, including
BMW models, and other applications, though in these the metal base is normally cast with the compartments in place, so the use of the term cloisonné, though common, is questionable. That technique is correctly referred to by goldsmiths, metalsmiths and enamellists as champlevé. File:Dorestad Brooch AvL.JPG|The

Georgia China From Byzantium or the Islamic world the technique reached
China in the 13–14th centuries; the first written reference is in a book of 1388, where it is called "Dashi ware". No Chinese pieces clearly from the 14th century are known, the earliest datable pieces being from the reign of the
Xuande Emperor (1425–35), which however show a full use of Chinese styles suggesting considerable experience in the technique. It was initially regarded with suspicion by Chinese connoisseurs, firstly as being foreign, and secondly as appealing to feminine taste. However, by the beginning of the 18th century the
Kangxi Emperor had a
cloisonné workshop among the many Imperial factories. The most elaborate and highly valued Chinese pieces are from the early
Ming Dynasty, especially the reigns of the Xuande Emperor and
Jingtai Emperor (1450–57), although 19th century or modern pieces are far more common. The Chinese industry seems to have benefited from a number of skilled Byzantine refugees fleeing the
Fall of Constantinople in 1453, although based on the name alone, it is far more likely China obtained knowledge of the technique from the middle east. In much Chinese
cloisonné blue is usually the predominant colour, and the Chinese name for the technique,
jingtailan ("Jingtai blue ware"), refers to this, and the Jingtai Emperor. Quality began to decline in the 19th century. Initially heavy
bronze or
brass bodies were used, and the wires soldered, but later much lighter
copper vessels were used, and the wire glued on before firing. The enamels compositions and the pigments change with time. Chinese
cloisonné is sometimes confused with Canton enamel, a type of painted enamel on copper that is more closely related to
overglaze enamels on
Chinese porcelain, or
enamelled glass. This is painted on freehand and so does not use partitions to hold the colours separate. In Byzantine pieces, and even more in Chinese work, the wire by no means always encloses a separate color of enamel. Sometime a wire is used just for decorative effect, stopping in the middle of a field of enamel, and sometimes the boundary between two enamel colors is not marked by a wire. In the Byzantine plaque at right the first feature may be seen in the top wire on the saint's black sleeve, and the second in the white of his eyes and collar. Both are also seen in the Chinese bowl illustrated at top right. File:Shrine with an Image of a Bodhisattva.jpg|Chinese shrine for a

Important Cultural Property in Nagoya The Japanese also produced large quantities from the mid-19th century, of very high technical quality. During the
Meiji era, Japanese cloisonné enamel reached a technical peak, producing items more advanced than any that had existed before. The period from 1890 to 1910 was known as the "Golden age" of Japanese enamels. An early centre of
cloisonné was
Nagoya during the
Owari Domain, with the
Ando Cloisonné Company the leading producer. Later centres were
Kyoto and
Edo, and Kyoto resident
Namikawa Yasuyuki and
Tokyo (renamed from Edo) resident
Namikawa Sōsuke exhibited their works at
World's fair and won many awards. In Kyoto
Namikawa became one of the leading companies of Japanese
cloisonné. The Namikawa Yasuyuki Cloisonné Museum is specifically dedicated to it. In Japan
cloisonné enamels are known as
shippō-yaki (七宝焼). Japanese enamels were regarded as unequalled thanks to the new achievements in design and colouring. File:Matching Pair of Cloisonné Vases, c. 1800-1894.jpg|Matching Pair of Cloisonné Vases, c. 1800–1894, from the Oxford College Archives of

House of Fabergé, Russia, before 1896 The first Russian
cloisonné developed from Byzantine models during the period of
Kievan Rus, and has mainly survived in religious pieces.
Kiev was perhaps the only centre. The industry stopped with the
Mongol invasion of Russia but revived in
Novgorod by the end of the 14th century, now using champlevé. Cloisonné barely returned until the 19th century, when it was used in revivalist styles by the
House of Fabergé and
Khlebnikov. Fabergé developed a style of raised and contoured metal shapes rising from the base plate, which were filled, though more thinly than in most cloisonné (effectively painted), leaving the metal edges clear. This is usually called cloisonné or "raised cloisonné", though the appropriateness of the term might be disputed, as in other types of cloisonné the surface is smooth, which is not the case with these. ==Modern process==
