Bi-Metallic: Working with 18k Gold and Sterling Bimetal
This three-week virtual class will cover the basics of working with bimetal from designing, texturing, soldering to other metals to forming and more!
Bi-metal sheet is an ideal material for jewelers who require karat gold accents. It consists of a layer of karat gold bonded to a layer of sterling silver. The karat gold layer can be engraved, patterned, roll printed, or removed by any method to expose the sterling silver layer underneath to create interesting surface embellishments and designs. It can be formed, soldered to other metals, and have Keum-boo applied to it. A versatile and wonderful way of adding gold to your work without incurring the cost of solid gold sheet. The goal of this class is to use 18k bimetal in a variety of ways to create new work with bits of gold!!
