津軽烏城焼TSUGARU UJOYAKI

Nature Glaze—Embodiment of
Nature’s Vitality

After nurturing a high-temperature flame in the kiln, the wood turns to ash and falls onto the works like snow. As the temperature in the kiln goes even higher, the ash melts into a vitreous entity. This is Nature Glaze. Reminiscent of precious jewels, which are created through natural phenomena, Nature Glaze appears on each piece as a one-of-kind crystalline formation after going through numerous transformations in the kiln. Enjoy the Nature Glaze of Tsugaru Ujoyaki—the synthesis of strength and beauty.

Characteristics of the Kiln and Wood

At Tsugaru Ujoyaki, we use two kinds of kilns: a cave kiln and a climbing kiln. We value the variance in these kilns, as each presents a different flow of air and flame, a different way of raising the temperature, producing enormously diverse “landscapes” on the works. Likewise, the Japanese red pine used as fuel has distinct characteristics depending on its age, climate during growth, timing of harvest and chopping. Every firing is unique; identical conditions can never be recreated. Watching the fire, listening to the fire—these are the keys that lead to beautiful masterpieces. When the skilled craftsperson’s instinctual grasp of temperature and oxygen levels resonates with the characteristics of the timber, the kiln, and the potter—this is when a work that goes beyond imagination is created.

Handmade Tools

A vessel is formed by adding string-shaped clay, one by one. Praying that it will withstand the flame in the kiln, the potter carefully taps the work both from inside and out to ensure durability. This “tataki method,” thought to have been around since ancient times, still remains as an indispensable practice in handmade pottery—a technique that embodies the craft’s origin. The supporting wood (anvil) and tataki panel are both handmade by the potter, and engrave the vitality of wood into the earthen walls of each work. At Tsugaru Ujoyaki, where we stick to making works by hand rather than relying on molds, the techniques and spirits from ancient times are still very much alive.

Museum and Studio

At the Nature Glaze gallery, the finest Nature Glaze works by Rikei Imai are exhibited and available for sale, along with everyday tableware such as cups, plates, tea ceremony cups, and flower vases. All items are handmade in our studio. At the Old Pottery and Ceramics Museum next door, you will find a permanent display of works that influenced Rikei’s artistic practice, such as pots from the Six Ancient Kilns and Old Imari, as well as ancient pottery and porcelain from various areas.
