In this category, you find the tools needed for electroplating.
Electroplating is made by covering a metal (e.g. silver or bronze) with a thin layer of another metal like gold. This is called gold-plated. The thickness of the layer varies but is typically between 0.5 and 2.5 microns.
An electric current passes through a solution containing metal ions. The ions are attracted to the piece which causes them to bond with surface of the base metal. The result is a very thin layer of gold, silver, copper, nickel or any other metal. You can apply this thin layer in a bath or with a pen (electroplating pen).
