What colour is Yeomsaek?
Yeomsaek is a traditional Korean way of dyeing fabric using natural materials. The process is best known for its use of indigo, which produces a deep blue colour on cloth. Other natural dyes like tea, saffron and gardenia are also used. The indigo-dyed fabric stands out for its rich blue shade, which is achieved through a careful process involving fermentation and exposure to sunlight.
Where does Yeomsaek come from?
The word 'yeomsaek' comes from Korean and refers to the act of dyeing. Indigo dyeing, or jjock-yeomsaek, has a long history in Korea and was especially valued for royal and wedding garments. The Naju area, with its wetlands along the Yeongsan River, is central to this tradition because it provides ideal conditions for growing indigo plants.
How is Yeomsaek made?
To make indigo dye for yeomsaek, indigo plants are harvested before flowering and soaked in water in earthenware jars. After several days, the leaves are removed and the water is mixed with lime made from powdered oyster or clam shells. The dried leaves are burned to make ash, which is added as lye. The mixture is stirred and fermented, then fabric is soaked in the liquid. The cloth turns yellow at first, but sunlight changes it to deep blue.
Where Yeomsaek is used
Yeomsaek is mainly used for dyeing textiles, especially for traditional Korean clothing. Indigo-dyed cloth has been important for royal garments and weddings. The process is still practised today, with masters like Jung Gwan-chae keeping the tradition alive in Korea.
