[506] Back to Basics: Electroplating & Electropolishing of Jewellery
Electroplating is a method to put a metal coating onto an object, in our case a piece of jewellery, by placing it in a solution containing the metal to be plated and passing an electrical current through the piece and the solution. It is possible to electroplate coatings of most pure metals and even some alloys. In this paper, we shall concentrate on the electroplating of gold and gold alloys and rhodium – one of the platinum group of metals with a good white colour and tarnish resistance - for decorative applications. Electroplating is a comparatively quick and easy process to carry out and does not require major investment in costly equipment. It can be done successfully with very simple, basic equipment. Finished carat gold jewellery may be electroplated with gold for several reasons.... (2002)

[71] Cleaning Metal Surfaces
For all metal coloring and electroplating a clean metal surface is essential. The cleaning process must remove mineral oils, organic oils and greases as well as traces of chemicals on the surface. It must remove oxidation which might interfere with the metal coloration or plating adhesion and it should possible activate or roughen the metal surface to better receive the treatment.... (2002)

[1016] Electroforming for Innovative Design
There are four principal methods of producing jewellery today: Hand making, using traditional craft skills, Investment (Lost wax) Casting, Pressing (stamping) and Electroforming. More than 50 % of all jewellery is produced as hollow parts; this is mainly realized by using either a pressing technique or electroforming. The advantages of hollow jewellery are wearer comfort on the one hand, such as in the case of ear ornaments or brooches, and price on the other hand, since hollow parts are less expensive than solid parts due to precious metal savings.....

[595] Electroforming Step-by-Step
Electroforming is the process of controlling the metal deposit from an anode metal, through electrolyte solution, onto an electroconductive surface. Basically, a skin of metal is built up into a rigid structure. The materials you will need to get started are as follows.... (2004)

[172] Electroplating rectifier safety thoughts
The "General Safety Rules for Tools" article applies here too, as with all power tools. Read the instruction manuals and directions most carefully. Plating and stripping solutions usually contain cyanides, bases or acids which, if mixed together, are used improperly or carelessly or come in contact with a cyanide plating solution can release hydrogen cyanide gas, which was used by the Nazis in the gas chambers and is still used in gas executions in the United States....
