Gold plating, making of gold potassium cyanide

If you want to use eplating using gold potassium cyanide you will have to take a lot of safety precautions. The method I use is much simpler. I have experience with eplating thin layers of gold on top of gold and palladium substrates (thin is anything between 100 nm and a few microns).
