Keum-boo Intensive

Keum-boo is an 11th century Korean technique that combines gold and silver to create beautiful surfaces and patterns. This intensive three-session virtual workshop explores the traditions of Keum-boo with a variety of techniques and variants to create jewelry which combines gold and silver in an economical way.

Students will learn about the properties of gold and silver foils, how to create their own foils, and multiple application methods in combination with embossing, stamping, roller printing, and solder inlay. This course will also cover innovative tips and tricks for combining keum-boo with collage techniques, stone setting, soldering, Argentium silver, and PMC, as well as proper clean up and framing to create refined and finished pieces of jewelry.
