Island Mumyoi Ware
Mumyoi (pronounced moomyoee) is a type of pottery made from Mumyoi
Clay, which contains ferrous oxide and is obtained near the old gold mine on
Island, a small island off of Japanís
west coast noted for its hot springs.
Unlike other pottery, Mumyoi requires extra processing efforts;
raw-polish, a process that polishes the products with cotton cloth before
baking, as well as a process of polishing with sand after baking. The particles
of clay must be extremely fine, a quality which can only be obtained through an
energy intensive filtration process using a clay-water mixture.
Mumyoi pottery is baked in a kiln at a high temperature and becomes
very dense and contracts about 30% from the original size, making the finished pottery
exceptionally hard. Genuine Mumyoi produces a clear metallic sound when tapped.
The more Mumyoi pottery is used, the more beautiful its finish becomes.
Originally, Mumyoi was used for medicinal purposes such as
relieving symptoms of palsy, digestive problems, burns, and helping to stop
The Gyodoku Pottery maker is dedicated to the continuous endeavor of producing
conventional Mumyoi pottery, developing new glaze formulas by mixing together
natural and non-organic substances such as rock, stones, and the ashes of
plants and trees as well as pursuing the beauty created by Yohen.
Also known as a kiln mutation (or kiln effect), Yohen is a
technique of kiln firing which produces varieties of colors using a climbing
kiln (multi-chambered kiln) with each successive chamber at a higher (and thus
hotter temperature) level than the previous.
Vessels of Mumyoi ware have been gaining popularity since they
richly enhance the drinking experience of green tea, coffee, sake, and beer.
