Electroforming is a metal forming process where metal is grown by electrodeposition onto a substrate. The electrolytic bath is used to deposit metal onto a conductive surface. In other words you are growing a layer of copper (or other metal) onto an object that has a conductive coating. The machine used to conduct the copper is called a rectifier. The end result is a natural surface of pure copper. This is such an awesome process to do and observe, and you can preserve a great variety of nature’s objects and set gemstones this way.
