Keum Boo Like You Never Knew...on Steel!


The ancient art of Keum Boo — bonding fine gold foil to silver—works brilliantly on steel too. In addition, the foil can be gold or silver, which bonds beautifully to steel and offers a low-cost alternative to gold. As an added bonus, the patinas that darken steel leave the shine of the gold and silver virtually untouched, so the contrast with steel is extra vibrant. This shorter, streamlined is being offered to former students who have a clear understanding of the basics of working with steel, including patinas and sealers. Exceptions will be made for those who have worked with mild cold rolled steel in jewelry making and are confident in the basics.


In this workshop, you’ll learn how to create jewelry with beautiful Keum Boo on steel including:

  • Prepping steel for Keum Boo (hint: no depletion gilding is required as with silver).

  • Handling and cutting original designs in the delicate foil, including tools and techniques to help refine your patterns.

  • Bonding silver and gold foil to steel using a torch and a tabletop kiln.


  • Choosing and using the right tools (burnishers and brushes) to bond the foil firmly.

  • Applying a chemical patina to steel jewelry with Keum Boo, including techniques for removing excess patina from the foil.


Whether you have done Keum Boo before or not, this workshop offers brand new techniques on steel. You’ll create at least one finished piece of jewelry with Keum Boo in this fast-paced and creative workshop.


This workshop runs for June 29 from 10:00 a.m. until 12;30 p.m. PST. The live online Zoom class will consist of brief lecture, pre-recorded demos, class discussion and an assignment. Then June 30 at1:00 p.m. you’ll be invited to attend an open studio session to discuss progress, ask questions and trouble shoot any issues.
