a process where a layer of copper is deposited on the item to be plated by using electric current. Often the items are given in a metallic basket, which is immersed into the electrolyte. As anode serves copper in the form of balls. There are two systems: in the alkaline process copper cyanide is used which gives a thin layer with good adherence. In the acidic system mainly copper sulfate or sometimes copper pyrophosphate is used, which gives a more glossy appearance.
