This is an Edo-period Mino gray-glazed sake cup. Ten years ago, it might have been classified as Yellow Seto, but now it's generally called gray glaze. Some people still consider it Yellow Seto. Pieces from old collections are often still identified as Yellow Seto. Regardless, the entire piece has fine crackle staining, indicating it has been well-used. As the images show, there are kiln cracks in the interior and on the base. Resin has been thinly applied inside the foot, possibly to prevent leakage (see image 12). It comes with a paper-lined box and a shifuku (protective silk pouch), likely commissioned by a tea ceremony enthusiast. I believe this item is nearly impossible to obtain nowadays. Diameter: Approximately 7.9cm Height: Approximately 3.7cm Sizes are approximate. The actual item may differ slightly in color from the images. As it is an antique, there are age-related scratches and stains. Type: Pottery Type: Sake vessel Type: Guinom (sake cup) Type: Ochoko (small sake cup)
