Created by imitating the form of the leather prototype (mostly used by the nomadic people), this flask features a small cup-shaped oval mouth with umbrella-shaped cover which was adorned with moulded patterns, a short and thin neck, arched shoulders with ridges which were reminiscent of the stitching lines of the leather flask. Two pairs of lug handles were moulded on the shoulders for belt to carry. Both the front and back sides are decorated with incised floral motifs, and the parts under of the lug handles are decorated with plantain leaves. In general, the modelling of the flask is smooth and mellow, rustic and elegant. The flask is fully coated with palegreen glaze, which is fine and glossy, just like the green emerald. The ceramics of such form indicated that there were custom-made products by the Yue kilns for the Northern China and the merchants from the Western Regions, alternatively the exported items of the Yue kilns were brought to the China proper via the Silk Road.

The ruins of the Yue kilns of the Tang dynasty lie at Shanglinhu lake of modern Ningbo in Zhejiang province. The porcelains from the kilns were famous for the tender and graceful shapes, mild jade-like texture, and the beautiful glaze colors, thereby they came into being the best ceramics in the south of China, rivaling with the then ceramics of Xing kilns in the north, hence forged a saying “Celodan of the South, White in the North” at the time.
