This is a tea bowl of Kourai Seiji (高麗青磁 Korean Celadon) made in around 130 years ago. It has a small but rather tall foot, which makes it a cute looking. The tall foot, called koudai (高台 tall-stand), is a feature of tea bowl intended to provide a comfortable hold of the bowl when hot tea is made inside. The crackle glaze (ao hibi 皸) is attractive, and almost invisible raised decorative lines can be found around the lower body, on both inside and out.
