Keum-boo (also Geumbu, Kum-Boo or Kum-bu meaning "attached gold") is an ancient Korean gilding technique used to apply thin sheets of gold foil to silver. Possible examples of this technique have been dated to the second half of the first millennium B.C. and from the early first millennium A.D.

Traditionally, this technique is accomplished by first depleting a surface of sterling silver to add a thin layer of fine silver. Next, a piece of 24-carat gold foil is permanently applied to the surface with heat and pressure.

Students will learn Kumboo through demonstrations and will produce a piece as an example of the technique. Students should be at an intermediate level, but all levels are welcome.

Skill Level: Beginner/Intermediate
