BOWL / TUBE / TEA BOWL, Gray Earthenware, proto-celadon, 2, Spring & Warring States（770–221BCE）

This is an early gray glaze known as proto-celadon, originating from ancient China. Crafted during the Spring and Warring States period in the Jiangnan region, this bowl exhibits a distinctive gray earthenware body, as the celadon glaze has partially flaked away, revealing the underlying clay. The piece is well-fired, showcasing the beauty of its gray earthenware, and presents a dignified form characteristic of the earliest tube tea bowls. It invites use for tea or floral arrangements.
