Stoneware

According to the American Ceramic Society, stoneware is typically fired at 1,150–1,300°C, with or without glaze, producing a dense, durable body with a water absorption rate of about 0–10%. By this definition, many traditional Japanese wares other than porcelain fall within stoneware.

Japanese terminology differs from the Western system. What the West classifies as stoneware is described in Japan with separate terms: toki generally refers to pottery made from clay, while sekki refers to high-fired wares with a dense, hard body whose properties are closer to porcelain.
