I am pleased to offer this beautifully made antique Chinese Monochrome Bowl or deep plate from 1820 -1850, or Xing Dynasty Daoguang era. It is made from porcelain, likely from the kilns of Jingdezhen, made in the style of Long Quan - famous for carved or incised porcelain in a celadon glaze which reached the peak around AD 1100s, Song Dynasty. Just before 1800 during Qian Long reign, the talented craftsman from Jingdezhen was able to bring some of the most prized ancient Chinese porcelain styles (like Jun, Guan, Ding, etc.) back to life and combined with the most recent (at the time) monochrome glaze with bright colors to re-create and enhance the glory. This is one of the fine examples from that era. The bowl measures about 9 inches across, 1 3/4 inches tall. the high shine glaze, the light celadon color at the underside and the fineness from the porcelain reveals the time period and place of origin. The rim is slightly scalloped from the carving of the bowl, in the lotus flower shape. The carving is top notch, reflected the finest craftsmanship during the peak (or one of the peaks, rather) of Jingdezhen's glory. the glaze inside the bowl has superficial worn from nearly 200 years of service, but overall in good shape with no chips, no cracks, no glaze crazing (which you don't see often from Jingdezhen's porcelain, and one of the reason's for it's fame). Do observe a few firing flaws on both size from the impurities of the clay, or another evidence of the age, rather. Please inspect pictures carefully and ask any questions should you have.
