Size: Approximately 8.5 cm high, 11.3 cm wide This is a rare piece, an extremely uncommon find. It's relatively thinly made, weighing about 286g. The bottom is made with a "ita-okoshi" technique, similar to the iron-blackening pots sometimes seen. This type of abacus bead shape can be found in early Joseon Dynasty or early Edo period Karatsu ware. The question is, when was this Tamba piece made? I am not knowledgeable enough to specify, but I believe it is undoubtedly an old work. Regarding imperfections: ① There are bird's foot-shaped kiln cracks on the bottom, but they do not go through to the inside and do not leak water. ② There are a few small chips on the underside of the rim's return.
