This method of etching uses a prepared ferric chloride solution which also contains hydrochloric acid. This 'etchant' is not a pure acid, but etches copper and copper alloys (like brass and bronze). It will not work on silver. It is available from electronics supply shops, such as Radio Shack or from chemical suppliers. It is generally used to clean or etch copper circuit boards. It can also be found at some printmakers' supply stores.... (2004) Complete Story
Metalsmiths and enamelists have used ferric chloride for several years as a safer alternative to nitric acid for copper and brass etching purposes. Although it is generally thought of as etching with an acid, ferric chloride is actually a salt. Etching and resist removal solutions recently developed by Friedhard Kiekeben have greatly improved the process and final product, as well as safety, cost and simplicity.
This article summarizes my experiences with these exciting methods for etching metal and removing resists. I have also included my own observations as well as an overview of the etching process, resists, equipment and materials necessary.... (2004) Complete Story
Etching uses chemical corrosion rather than mechanical force to selectively remove metal. Simply put, the idea is to cloak parts of an object with an acid-proof paint then submerge the piece in acid. The caustic liquid eats away at exposed areas to create a relief. When the proper depth is reached the piece is withdrawn, rinsed and cleaned to reveal a pattern of raised and lowered sections. The process can be used for delicate linear drawings, for bold reliefs, for letters, and as a preliminary step for enameling, niello, or inlay.... (2001) Complete Story
The use of PnP paper-originally designed to create printed circuit boards-to meet the artistic needs of metalsmiths, jewelers, and enamelists. With results similar to photo etching, but without the expense and more complex procedures, the heat transfer method using PnP has revolutionized the world of artistic etching. Now, the procedure is not only used throughout the USA, but also in many other parts of the world... (2001) Complete Story
I have found through may research on metal etching that there is a plethora of information out there. I hope by compiling it and offering it to you, you will be better able to choose the best option for your champleve needs. There are of course means other than etching to prepare a surface for champleve enameling, namely piercing and soldering, forming with a hydraulic press, stamping or engraving. This article however will deal only with the etching options..... (1998) Complete Story
