Shaped like a phoenix carrying a zun vessel on its back, this vessel is of a type commonly called tianji hu or “celestial fowl vessel” in Yixing literature. It takes its shape from the archaistic bronze prototypes made during the Ming dynasty. It is stamped with the square seal Chen Mingyuan in raised seal script. Cobalt was added to the greyish pearskin clay, causing bubbles during firing. Dark specks of iron also appear on the clay.
