The removal of gold plating from jewelry is often desirable if the gold surface has become tarnished or lackluster. In most cases it will not be possible to preserve the gold as it is removed. Gold plating is very thin, usually over a silver or copper base, and the process will typically destroy the thin layer of gold as it is removed.
Plating Preparation and Removal
Fill the glass jar or basin with denatured alcohol. Add three spoonfuls of the boric acid.
Put on gloves and glasses. Stir the boric acid/alcohol solution. Grip the the piece of jewelry with the pliers.
Dip the jewelry in the boric acid/alcohol solution while the stirred solution is in motion. Remove the jewelry from the solution and move away from the jar or basin.
Heat the jewelry with the torch. The alcohol will burn off, leaving a white powder of boric acid. Remove the torch from the jewelry as soon as the flame is visible.
Make sure that the item is sufficiently coated with boric acid. If not, allow the item to cool completely and repeat steps 3 and 4.
Apply the torch again. The gold will quickly disappear.
