Although the materials and glaze colours on this vessel are typical of Liao wares, the technique of precisely controlled outlining and giving texture to the decoration is unusually fine. Similar materials and colouration to the current lot can be seen on a jar excavated in Liaoning province (illustrated in Ancient Chinese Tea Wares, Urban Council of Hong Kong, 1994, pp. 86-87, no. 24), but the decoration on this jar is much cruder than that seen on the current vessel. Much more skilful incised decoration, closer to that seen on this vessel can be seen on a fine Liao white flask in the collection of Dr. Simon Kwan (illustrated in Song Ceramics from the Kwan Collection, Hong Kong Museum of Art, 1994, pp. 396-7, no. 180) although the decoration on the flask includes no texture strokes. It is interesting to note that the branches on the current vessel bear fruit, rather than flowers - in this case peaches and oranges. A small dish, illustrated in Toji Tekai, vol. 40, Liao, Heibonsha, Tokyo, 1974, no. 16, bears a single pomegranate in green and amber glaze on its interior, which might more commonly be expected to be decorated with a flower.
The result of thermoluminescence analysis report, Oxford C101n56, is consistent with the dating of this lot.
