Ewers of this type were first made in the Yue kilns during the mid-Tang period, and functioned as wine vessels. An almost identical example is in the collection of Shanghai Museum, currently on display at the museum. Another similar Yue ewer but of similar size (14.3 cm. high) and of slightly stouter form, is in the collection of the Palace Musuem, illustrated in Zhongguo meishu quanji - taoci (zhong), Shanghai, 1988, pl. 63 (fig. 1).
