Etching is a method of removing exposed metal and retaining protected metal from a surface so as to create a design or texture. In our shop, we accomplish that with non-ferrous metals in one of two ways, both of which use a etching bath (mordant), a pattern that adheres to and protects the metal surface (resist), and a source of electrical current to initiate a chemical reaction. Parts of the metal are covered and protected by the "resist", while the exposed parts are eaten away by the electric current to reveal a design.
The Jewelry and Metal Craft Shop currently supports two methods of etching non-ferrous metals: electro-etching and salt-water etching.
