THE rice bowl is designed with human hand in mind: the 12 centimeter diameter of the rice bowl is derived from the average diameter of a Japanese person’s hand when a half-circle is made with the thumb and pointing finger. In other words, it is the perfect size that naturally fits a hand.
The height is set at half the diameter, which is 6 centimeters, as the ratio between the pointing finger and thumb is said to be exactly 2:1.
Once the shape is defined, THE rice bowl is made in five different regions of Japan that are known for their distinct pottery styles, in order to offer a comprehensive view on Japanese pottery's various expressions: the styles include Arita (Saga Prefecture), Kiyomizu (Kyoto Prefecture), Shigaraki (Shiga Prefecture), Seto (Aichi Prefecture), and Mashiko (Tochigi Prefecture).
To enhance and emphasize the characteristics of each style, the clay, glaze, and finish are all white-colored.
SETO (Aichi Prefecture)
Considered one of the ‘Six Old Kilns’, “Setomono” (Products of Seto) were so widely used in the Eastern area of Japan it became a generic term for ceramics. In the middle ages, Seto was said to be the only region that applied glazes to their pieces. The kaolin layer of the Seto region is known as one of the few locations in the world that contain an abundance of fine clay and quartz sand ideal for earthenware. Seto's rice bowl uses the exemplary “Kosome” clay, and a clear glaze is applied to fully enjoy the crackled texture.
