Rather unusual 1930s Japanese porcelain covered inkstone with underglaze decoration. The side of the base is inscribed with a very long text, the top of the cover has a short poem and a figure of a man in robe lighting his pipe from ambers in the brazier. Possibly Arita ware, very nice modeling of the central raised area with rougher side surface for grinding ink, remnants if dried ink in the well. Marked on the bottom in seal script with 4 characters which can be translated as “Made with indigo blue in Eastern marshes”. Excellent quality painting with sharp outlines and delicate washes, in excellent condition. Diameter 4 1/8 inches, height with cover 2 inches.
