Ottchil Korean Natural Lacquer Application

옻칠 (Ottchil)

Ottchil is the Korean natural lacquer tradition — the application of sap from the lacquer tree (Rhus verniciflua) to wood, fabric, metal, or ceramic surfaces through multiple coats of progressive refinement to produce the characteristic deep, luminous black or colored surface of Korean lacquerware. Korean ottchil is distinct from Japanese urushi and Chinese qi in its specific application technique, curing conditions, and aesthetic outcomes — Korean lacquer tends toward a deeper, more matte-luminous surface than the mirror-bright Japanese urushi. The ottchil process involves extracting sap from the lacquer tree, filtering and refining it, applying successive coats by hand or brush in a humidity-controlled environment, and allowing each coat to cure fully before the next — a process that can take months for fine work. Tongyeong city in South Gyeongsang province is the primary ottchil center, home to the Ottchil Museum directed by Kim Sungsoo, whose work is in the collections of the Seoul Museum of Art.
