Ryukyu Tsuikin Relief Lacquer Appliqué

堆錦 (Tsuikin)

Tsuikin (堆錦) is Ryukyu lacquer's relief-appliqué technique. Thoroughly heat-processed kurome lacquer is mixed with pigment and beaten with a hammer into a pliable cake, tsuikin-mochi, one for each color. The cake is rolled thin and fixed to a temporary board with lacquer. There it is patterned, modeled in relief or layered, then peeled off and applied to the object to fit the design. Ryukyu's official history, the Kyūyō, credits its invention to Higa Jōshō in 1715. But the technique already appears in a Ming Chinese craft book of the early 17th century, so it had spread from Ryukyu to China before that date, and similar techniques exist in Thailand. It can be die-cut for repeated motifs, combined with raden, or carved. Splitting the cake into layers and blended gradations (bokashi) were developed in the Taishō era. Trade sources say roughly 80% of Ryukyu lacquer carries tsuikin decoration, which makes it the tradition's signature technique rather than chinkin.
