This is an antique Ko-sometsuke small plate from the Ming Dynasty in China. Ko-sometsuke (old sometsuke) is a type of blue and white porcelain made in the Jingdezhen kilns, mainly during the Tianqi period (1621-1627) of the late Ming Dynasty. A major characteristic is the "mushikui" (worm-eaten) effect, where small chips are visible in the glaze due to firing in the kiln. Although it may appear roughly made at first glance, its unique elegance has made it a favorite of tea masters and other connoisseurs since ancient times. This piece is also of the same style as the Ko-sometsuke plate that Rosanjin Kitaoji was known to have favored and used (illustrations and explanations by Rosanjin himself are provided in photos 5-6). This piece features a hand-painted design of floral motifs, which are representative of Ko-sometsuke, executed with a skilled touch. The inside of the foot ring clearly shows the radial pattern that is characteristic of Ko-sometsuke, making it a wonderful piece.
