Introduction to Electric Etching is taking place at NYC Resistor on Sat, Mar 16. Tickets are available on Eventbrite.
Electric Etching is the process of using electricity and an electrolyte to etch a pattern onto a metal surface. A non-conductive pattern is placed over the material to be etched. The metal to be worked on is then grounded. The live wire is then connected to the applicator. When the applicator is applied to metal surface, wherever is not masked will be etched. The advantage of using electricity to etch metal is that it is a very predictable process. If it is desirable to have a deep etch, a higher current or longer exposure time increases the prominence of the edge. This class will cover the basics of electric etching. It’ll be broken down into 3 parts. The first part will cover a demonstration of the etching process. Students will be able to practice on a scrap piece of metal. In the second part of the class, students will be making their own masks out of Vinyl. In the 3rd part of the class, students will etch metal plates that we will provide or items that they want etched. After etching, students will be polishing the surface to protect the etching. We DO NOT recommend etching sentimental items, items of great value or family heirlooms.
