清乾隆 宜興段泥團龍紋盌

Chen Jinghou was a potter active during the Qianlong period, and K.S. Lo in The Stonewares of Yixing from the Ming Period to the Present Day, Hong Kong, 1986, p. 264, records him as such. For another example of his work see the bowl carved with lotus petals illustrated in Yixing Zisha Wares in the Palace Museum, Beijing, 2009, p. 252, pl. 156, where it is dated Qing dynasty.
A very similar bowl with the same mark illustrated in Oriental Works of Art, Gerard Hawthorn Ltd., London, 9 - 22 June 1997, no. 11, where it is dated 18th century, was subsequently sold from the Mr. and Mrs. Gerard Hawthorn Collection at Bonham's, Hong Kong, 28 November 2011, lot 215, where it was dated to the Qianlong period.
