SADO-MUMYOIYAKI（POTTERY）
Mumyoi ware is made from red clay containing a large amount of iron oxide called “Mumyoi-do,” and was first produced in the early 19th century as Raku ware in red color mixed with Mumyoi-do, and the present Mumyoi ware, fired at high temperature and hardness, was completed in the Meiji period.
In principle, clay and glaze materials produced on Sado Island should be used, but with the advancement of technology and the ingenuity of potters over the years, glaze materials and forms have become more diverse in recent years, and each kiln produces products with different characteristics.
Feature
The ceramic clay particles are fine and have a high shrinkage rate, shrinking by about 30% from the time of molding to drying. It is characterized by the property of being extremely hard and baked tight.
How to make
Because the clay is refined with water and passed through a silk screen, the particles are finer and the shrinkage rate is greater than that of other clays. After molding, the clay is polished with stones or an iron spatula to bring out its luster in its raw state, and after firing, it is further polished with refining slag from the Sado Gold Mine to bring out its unique luster. The more it is used, the more luster it acquires, and the more it becomes a unique and subdued object.
