This is a well-used sake cup. It's a vessel with a natural, aged quality that isn't just for show, but has a certain dignity. It's a perfect example of how the white clay has matured with use. If a teapot had this kind of atmosphere, the tea would surely taste delicious. The craftsmanship is quite meticulous, with a simple design that highlights the material, and a subtle groove added to the foot of the cup. I have no information on the maker, as I've never seen their work outside of this piece, and there are no records. To be honest, I'm not sure of the kiln site, whether it's Banko, Tokoname, or somewhere else entirely. The atmosphere suggests it might be from the Meiji era, but I'm personally estimating it to be from the Taisho to early Showa periods. No damage. Diameter approximately 7.2 cm, height approximately 4.2 cm.
