This is a red raku piece that shows signs of frequent use. I believe it's a rare item. Perhaps it's from the late Edo period, made in Kyoto. It has a tatami base, with some glaze flaking, and repairs and small chips on the rim. It could be used as a daily teacup. Alternatively, it could be used as a large sake cup, or as a small tea bowl for tea ceremony, or a tea bowl for a tea basket. It has spatula carving on two sides. Diameter: Approximately 7.9cm Height: Approximately 5.3cm I apologize for the dark images. The last two images are borrowed from the Asahi Shimbun's "Hagi Ware 400 Years Exhibition." Even old-timers don't know that red raku was also made in Hagi during the mid to late Edo period. I believe this item is from Kyoto, though. The size is approximate. As it is an old item, there are age-related scratches, stains, and wear. The color may differ slightly between the actual item and the images.
