Sake Set, Namako Tenmoku - 6 ounce bottle and two cups. Japanese Stoneware. Japanese ceramic artists, using techniques handed down through the centuries, create these unusual and uniquely Japanese pieces. A multi-process glazing gives a beautiful translucent finish to the deep blue, and a textured "volcanic rock" finish to the charcoal colored areas on each piece. Matches Namako Temoku dinnerware. Made in Japan.
