BOWL / TUBE / TEA BOWL, Gray Earthenware, proto-celadon, with wooden box, Spring & Warring States（770–221BCE）

This is an early gray glaze known as celadon, originating from ancient China. Crafted during the Spring and Warring States period in the Jiangnan region, this bowl exhibits a beautiful gray earthenware body, as the celadon glaze has partially flaked away, revealing the underlying clay. The piece is well-fired, showcasing the exquisite qualities of gray earthenware. It possesses a dignified form, characteristic of the earliest tube tea bowls, making it a perfect vessel for tea or floral arrangements.
