Plique-à-jour (French for "letting in daylight") is a vitreous enamelling technique where the enamel is applied in cells, similar to cloisonné, but with no backing in the final product, so light can shine through the transparent or translucent enamel. It is in effect a miniature version of stained-glass and is considered very challenging technically: high time consumption (up to 4 months per item), with a high failure rate. The technique is similar to that of cloisonné, but using a temporary backing that after firing is dissolved by acid or rubbed away.〔Campbell, 38-40; Ostoia, 78; (''Plique à Jour - Yesterdays Technique Today'' ), Bill Helwig, June 1992, Glass on Metal magazine〕 A different technique relies solely on surface tension, for smaller areas.〔(''The Art of Fine Enameling'' ), Karen L. Cohen, p. 10〕 In Japan the technique is known as shotai-jippo (shotai shippo), and is found from the 19th century on.〔(Japanese bowl ) in the V&A〕 ==History== The technique was developed in Byzantine Empire in 6th century AD.〔(Georgian Art Studio Phokani )〕〔(Lang Antiques )〕 Some examples of Byzantine plique-à-jour survived in Georgian icons. The technique of plique-à-jour was adopted by Kievan Russia (strong trading partner of Constantinople) with other enamel techniques. Despite its complexity plique-à-jour tableware (especially "kovsh" bowls) was used by its aristocracy. Russian masters significantly developed plique-à-jour technique: in addition to cells cut in precious metal they worked with cells made of silver wire. Unfortunately the plique-à-jour technique of Kievan Russia was lost after the crushing Mongol invasion in the 13th century. Some surviving examples are exhibited in the Historical Museum in Moscow. Western Europe adopted the plique-à-jour technique (cells cut in metal) of Byzantium. The term 'smalta clara' ("clear enamel"), probably meaning ''plique à jour'' appears in 1295 in the inventory of Pope Boniface VIII〔Labarte, Histoire des arts industriels, iii, Paris, 1865, p. 441〕 and the French term itself appears in inventories from the 14th century onwards.〔(''Recherches sur la peinture en émail dans l'antiquité et au moyen âge'' ), Jules Labarte, 1856.〕 Benvenuto Cellini (1500–1571) gives a full description of the process in his Treatises of Benvenuto Cellini on Gold-smithing and Sculpture of 1568. Pre-19th century pieces are extremely rare because of their "extreme fragility ... which increases greatly with their size", and the difficulty of the technique. Survivals "are almost exclusively small ornamental pieces". The outstanding early examples that survive are "the decorative insets in the early fifteenth-century Mérode Cup (Burgundian cup) at the Victoria and Albert Museum in London, a Swiss early sixteenth-century plique-a-jour enamel plaque representing the family of the Virgin Mary in the Metropolitan Museum of Art in New York,〔(Plaque in Metropolitan )〕 and the eight pinnacle points over the front of the eleventh-century Saint Stephen's Crown in Hungary".〔Ostoia, 78〕 The technique was lost in both Western and Eastern Europe. The technique was revived in the late 19th century movement of revivalist jewellery, and became especially popular in Russia and Scandinavia. Works by Pavel Ovchinikov, Ivan Khlebnikov, and some masters working for Faberge are real masterpieces of plique-à-jour. Russian masters predominately worked with tableware. Norwegian jewellers included David Andersen and J. Tostrup in Oslo,〔Marit Guinness Aschan and Rika Smith McNally. "Enamel." Grove Art Online. Oxford Art Online. 28 July 2010 (Subscription required ).〕 and Martin Hummer in Bergen. Art nouveau artists such as René Lalique.〔(National Gallery of Art )〕 and other French and German artists predominantly used plique-à-jour in small jewellery, though the Victoria & Albert Museum has a tray of 1901 by Eugene Feuillâtre (1870–1916).〔(Ring-tray by Eugene Feuillâtre ), V&A.〕 Currently plique-à-jour still not often used because it is challenging technically and mainly due to break in transferring of skills between generations of jewelers. Although some luxury houses (Tiffany in jewellery, Bulushoff in jewellery and tableware) produce limited numbers of products in plique-à-jour technique. Works in shotai shippo technique are also known from China and Iran. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Plique-à-jour」の詳細全文を読む スポンサード リンク
