 The Haibara Kiln was active from the end of the Kamakura period to the Nanbokucho period (1392-1333), the peak of the Koseto period, and is famous for producing a number of excellent products. This piece is made of water-ground molding, with a slightly bulging shoulder and a large overhang at the bottom. The design is characterized by the fine lines of the nail carving style characteristic of this period, with a design of leaves and trees filling the entire surface. The iron glaze is well melted, but the ash feldspar content is high, resulting in a blue-black candy glaze.
