Copper Pendant From Humble Plywood

Electroforming and electroplating are the processes by which a thin copper veneer is added to an object via electricity and a conductive solution. With the proper supplies, it is a relatively simple procedure but does require a bit of preparation.

In my case, I bought a self-contained kit. It was easier for me to get it all at once rather than piecemeal it out. Now that I’ve completed the process a number of items I wouldn’t hesitate to replace bits as needed without purchasing another kit.

The process involves starting with a dry object and sealing it with a finish. Next is applying a uniform coating of conductive paint to non-metallic objects. In this case, I made several items.

A Deathly Hallows symbol was cut on my CNC machine and prepared as stated. Spray with lacquer and then coated in conductive paint. It is then submerged in a conductive solution of copper sulfate along with a donor metal. In this case a copper coil or anode.

Honestly, I understand how it works, it still feels like actual magic. At least low-level alchemy. Here is a timelapse of a resin flamingo getting its copper coating.

The Hallows Pendant spent nearly 15 hours in its bath getting a thick layer copper before emerging with new life. From a humble scrap of plywood to a valuable copper pendant.
