拍品描述

A FINE COPPER-RED-GLAZED LANGYAO-TYPE BRUSH WASHER, QING DYNASTY China, 18th to mid-19th century. Well potted, the compressed body supported on a short foot and surmounted by a broad mouth with a gently tapered rim, covered overall in a vivid, finely streaked, deep red glaze, richly pooling at the edges and to the interior, thinning to white at the mouth and foot rims, and stopping neatly above the foot. The recessed base left white and marked with an underglaze-blue double circle. Dimensions: Diameter 10.5 cm The use of copper-red glaze at Jingdezhen was revived by the Kangxi Emperor after a decline in usage during the late 15th century. With the effort to reproduce classic Ming jihong ('sacrificial red') porcelains, Qing copper-red pieces quickly outnumbered their Ming counterparts. Nigel Wood in Chinese Glazes, London, 1999, p. 180, notes how the French Jesuit missionary, François Xavier d’Entrecolles (1664-1741), wrote letters giving detailed accounts of the copper-red production at Jingdezhen, the sourcing of the copper for the glaze, the recipes and the kiln location of the firing of these wares. Père d’Entrecolles was aware of the difficulties involved in the making of copper-red wares and his account confirms the high level of technical knowledge of the potters at Jingdezhen. Langyao is a type of copper-red glaze, that was developed at the Jingdezhen imperial kilns under the supervision of Lang Tingji (1663-1715), governor of Jiangxi Province between 1705 and 1712. This glaze turns red after being fired in a reducing or oxygen-deprived atmosphere. The glaze must be of a certain thickness to turn red, so areas where it is thin can be lighter in color, ranging from pinkish hues to pale celadon and sometimes even white. Literature comparison: Compare a related waterpot with a similar deep red glaze, dated to the Qing dynasty, 5.6 cm diameter, in the National Palace Museum, Taipei.
