The Suzu Pottery, an unglazed ceramic, was once disappeared completely, and the current Suzu Pottery was revived in 1976. Although the pottery is unglazed, the soil in Suzu region is rich in iron, therefore when it is fired at 1200℃, the ashes of the firewood melt and turn into a natural glaze, creating the charcoal gray color of the Suzu Pottery.
