Keum-boo Basics

Course Description

About this course

In this live, virtual workshop students will learn to add high karat gold to fine, Argentium, and sterling silver through the ancient Korean gilding technique of “keum-boo”, a process of applying thin 24k gold to silver using heat and pressure. Class will focus on learning and practicing the keum-boo method on fine and Argentium silver, and a video demonstration on sterling silver preparation will be incorporated into the course for students who have access to a torch and wish to work with sterling in the future. The keum-boo pieces that students complete in class can easily be turned into finished jewelry.

Class will be held live via Zoom during the designated time frame. A link to the Zoom room will be sent via email. 

Each session will be recorded and you will receive a password protected link to the recordings that expire after 30 days.

Please read the Materials & Tools tab!

"Growing up, I always was mesmerized by sparkling gemstones and metals and I often incorporate something illuminating into my designs. Whether or not I intricately plan a jewelry piece in advance of producing it or just spontaneously fabricate one as I go along, the result is inevitably something that is unique with a contemporary flair that complements, rather than overwhelms, a wearer. When designing jewelry or other metal work, I always think about whether I would wear it, use it, and/or display it. Anyone who knows me sees a reflection of me in what I design.

I produce fine contemporary jewelry and other metal designs primarily in the precious metals of gold, silver, palladium, and platinum. These are often further defined with the addition of texturing, gemstones and other unique lapidary, or resin inlay. I also manufacture photo-etched metal jewelry and etched cover plates that are attached to journals or are framed--wedding invitations, bar and bat mitzvah invitations, baby announcements, and the like. 

In addition to participating in art shows, sales, and doing commission work, I love providing instruction in jewelry design and metal fabrication.  My work can be seen and purchased at galleries and stores, as well as in my own online store.  Designing and fabricating engagement and wedding bands and other jewelry, often with people's stones, is particularly meaningful to me."
