Create ripples and waves in the surface of your silver with a torch. Then fuse gold leaf to the surface to create wonderful, abstract textures.

This online live zoom class will teach you all you need to know to prepare and reticulate your silver with a torch. Create fast, mixed metal and textured parts for your jewelry, or use these techniques to accent stone settings, pendants, earrings, rings, and more.

Techniques taught: 

• Depletion gilding
• Annealing
• Reticulation

• Keum boo (fusing gold foil onto silver alloys) 

When offered as a one day workshop, this zoom class is from 10-12:30 and 2:30-5pm, with a 2 hour lunch break.
