| [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)

| [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....

| [596] Notes from an Electroforming Workshop |
The size of the bath must correspond to the rectifier. You cannot have a huge bath and a small rectifier. The tank must be made of glass, polypropylene or polyethylene plastic. Plastic is preferred because there is less chance of breakage. You can get a plastic container from the plastic supplier in your community. A glass tank can be obtained from a fish or pet shop. Be aware of leakage.... (2004)
