Metal Etching Class
Taught by Carmen M. Almlie-Martinez
Metal etching has been around for hundreds of years and is one of the most amazing and magical techniques you can have in your artistic arsenal. The process is exciting which can be used to transfer images to metal. While some believe, etching can be intimidating, the truth of the matter is that when it is executed in the correct manner, it is a safe and efficient process.
For the etching process, we will need an etchant which removes metal particles from any areas not protected by some sort of resist (or mask). The most common form of etchant used for base metals (copper, brass, nickel silver, and pewter) is ferric chloride. There are several resists that can be used. The one we will use for this class is a blue acetate film called Press-n-Peel(PnP) paper. We will also cover and talk about some of the other resist that can be used – Rubber Stamps and Ink, Letraset Lettering, Permanent Ink Markers, Asphaltum, and Nail Polish.
We will also talk about other etching processes - Edinburgh Process, Electrical Process, and Galvanic Process. We will also go over what etchants are needed if one wishes to etch Sterling Silver or Gold.
