Excavated in the Tang City Relic Site of Yangzhou city in 1974, this pot is regarded as a rare treasure among all the ceramics made by Changsha Kiln given its large size, exquisite decoration and charming glaze. With a curly opening rim, high neck, bulging belly and flat bottom, this piece features two symmetrical flat-ring-shaped knobs, which are embellished with clouds patterns and the Chinese character of “wang”, meaning “king”. Its beige pottery body is covered with a coating of green-yellow glaze, and adorned with curly clouds composed of brown and green dots in different sizes, among which scatter motifs of lotus leaves and blossoms.
