Etching metal is a process where a design is placed on a blank piece of metal. The metal is then suspended in a solution that dissolves the metal in all places except where the design was placed. The metal must be checked often and the etching takes about an hour. I then sand and buff the piece and alter it (use different antiquing techniques). The results are often uncontrollable, but very surprising!
I use rubber stamps or permanent markers to place a design on blank metal (usually brass) disks. You can use almost any design, the possibilities are endless!
To etch the design, I use PCB Etchant Solution found at Radio Shack. *NOTE* This is a very caustic solution! Rubber gloves MUST be used, and the solution must be neutralized after use and disposed of properly. Neutralizing is done by adding baking soda until the solution stops bubbling.
If you are interested in trying this technique, feel free to contact me with any questions. Have fun with it, but be cautious and safe. Happy etching!
