Gosu is a blue pigment that has traditionally been used for ceramics, such as blue and white ware.
Thought to have been brought from China to Arita, Japan in the early Edo period, Gosu is now widely used for ceramics, not only in specific production areas.
Unlike other pigments, Gosu Blue does not fade, as the pigment is put on unglazed pottery.

Five Carefully-Selected Shades of Blue: Soekyu GOSU 1.0-5.0

Though collectively called Gosu Blue, the color shades widely vary from a deep sober blue, to a brilliant bright blue, and to a light blue with delicate expressions.
Soekyu Seitosho, with a particular preference for Gosu, developed five specific shades of blue and named them as ‘Soekyu GOSU* 1.0-5.0.’

Dami: A Traditional Technique to Enhance Gosu Beauty

A long-standing technique, called dami, for dying with Gosu is used for painting our wares with ‘Soekyu GOSU 1.0-5.0’ blue.
This technique uses a special large brush (called a dami brush), soaked with plentiful Gosu, to finely paint the ware, while controlling the amount of dripping Gosu paint by squeezing the brush with fingertips.
This requires skill, concentration, and above all else, patience.
We hope owners will enjoy the lively blue color of ‘Soekyu GOSU 1.0-5.0’ on our ceramics, delivered by this technique.

GOSU Responds to the Climate

No two GOSU wares are identical, since they are hand-painted and their color comes out differently depending on the season, weather, and humidity.
We hope that owners will appreciate and enjoy such individual character.
We work hard on producing ceramics every day, wishing to deliver a special piece for each owner.
