This item is from the early Showa era. It is Mino ware, celadon porcelain with a plum blossom pattern. The rim is also decorated. There are black spots, but these are not mold; they are iron particles (teppun). They will not come off even when washed. * The cause is thought to be the iron content in the clay that turned black during firing. If you are concerned, please refrain from purchasing. This is a practical medium-sized bowl that can be used for simmered dishes, salads, noodles, and rice bowls. Instant purchase is OK. Please refrain from price negotiations.
