Red Earth Diamond: A Gem-Like Luster Shaped by an Island of Gold
Mumyoi Ware is a distinctive type of pottery produced by firing Mumyoi clay, a reddish-brown, iron oxide–rich material obtained from the foothills of the Sado Gold Mine, at high temperatures. The finished pieces resemble freshly unearthed red earth and have a dense, smooth texture that feels as if it clings to the fingertips. The primary appeal of Mumyoi ware is its scarlet surface, which becomes increasingly polished and mirror-like with continued use.
HistoryA Story That Blossomed Beside Sado Gold Mine
Mumyoi Ware is a pottery tradition that has been passed down for over 200 years on Sado Island, Niigata. The tradition began in 1819, when Ito Jinpei used Mumyoi clay from local mines to make raku. In 1857, Ito Tomitaro established the foundation of the craft by introducing high-temperature firing (honyaki). During the Meiji period, artisans such as Miura Jozan and Ito Sekisui further improved the quality and developed durable ceramics fired at high temperatures, drawing inspiration from China’s Yixing ware. As a result, Mumyoi Ware became highly regarded as an art craft.
Formed from soil where iron and gold mix, its solid weight and calm, gem-like appearance give it a distinct presence in daily life.
OriginThe Gift of Gold And Silver Mines: Sado's Mumyoi Clay
The distinctive character of Mumyoi Ware results from the unique geology of Sado Island and its history of gold and silver mining.
Artisans mine red Mumyoi clay at the foot of the Sado Gold Mine, mix it with clay-rich soil, and dry it for over six months. They then pass the mixture through a coarse sieve, add water, and use water sedimentation to remove impurities and increase purity. Further sifting through finer screens selects only the finest particles, producing high-density clay that shrinks by about 30% during firing. This process gives Mumyoi ware its characteristic strength and lustrous sheen.
The ware is also known for its substantial weight and the distinctive crimson patina that develops with use over time.
