What a Relief!         
Keum Boo on Etched Steel
May 12-14

About This Live Online Workshop

Whether bas relief, intaglio or high relief, etching adds beautiful dimension to steel jewelry. The addition of Keum Boo—gold foil bonded to metal— elevates etched steel to a whole new level by creating a play of light and shadows across the dimensional surface. “What a Relief! Keum Boo on Etched Steel” is all about creating intense drama by electro etching steel and then adding a layer of fine gold or fine silver (or a combination of the two) that bonds seamlessly to the hills and valleys of the etched surface.
In this live online shop, you will learn to:

  • Work with mild steel, including sourcing, cutting, forming and soldering it.  Pre-class tutorials will be provided for those who have never worked with steel or just want a refresher. 

  • Create a dramatic etched design on steel through the use of different types of resists, including oil paint, laser transfers, stencils, and tape. 

  • Prepare the etching station, including the etchant and power source.

  • Monitor the etching process to achieve the best results.

  • Work with gold and silver foil to prepare it for the Keum Boo process. 

  • Roll your own foil if you choose to do so.

  • Bond the foil to steel using a torch or a small tabletop kiln. Both approaches work well.

  • Patinate your steel jewelry to make the bonded foil pop.

  • Seal your jewelry to protect it for years to come.Seal your steel je
