How to Anodize Copper

Anodizing copper is a chemical process that can be used to change the color of the metal and increase its resistance to corrosion. It’s a relatively simple process, and it’s becoming increasingly popular among jewelry makers, as well as those who work with materials such as pipes or wires. In this article, we will be discussing the basics of anodizing copper, including what tools you need and how to complete the process.

Gather Your Materials

The materials needed for anodizing copper are actually quite simple: all you need is distilled water, a power source (such as a battery charger), some electrical wire, oil-free sandpaper, conductive paint (optional), and of course, your copper piece. Before starting, make sure your copper piece is clean and free from any dirt or debris. If necessary, use sandpaper to carefully remove any imperfections. Once you have all of your materials ready, you can begin the process of anodizing your copper!

Anodize Your Copper

To start anodizing your copper piece, you will need to attach one end of the electrical wire to your power source and the other end to your copper item. Make sure that both ends are securely connected, so no electricity escapes during the process. Then add some distilled water into a container large enough for your piece—the more water added, the more intense colors you will get from anodization—and submerge the wired part of your item in it. Turn on your power source and let it run until you achieve desired results—it usually takes about 30 minutes for most pieces.

Optional Step: Color Paints

If desired, adding color paints can also enhance results when anodizing copper. This step is entirely optional but can lead to some interesting effects! To do this step after anodizing is complete, simply dip a brush into conductive paint (you can buy these at most craft stores) and coat over areas where colors are desired. Let them dry completely before removing them from a power source; otherwise, colors may not set correctly! Be sure to experiment with different colors until desired results are achieved!


Anodizing copper can provide unique looks for jewelry or other projects made with this material type! With just a few simple steps and materials, anyone can learn how to complete this chemical process at home in no time at all. If desired, adding color paints after anodization is complete can further enhance results – so don’t be afraid to experiment until the desired look is achieved! Have fun with it!
