Rainbow Electropatina - Solution for copper Jewelry
Rainbow ElectroPatina Solution for Copper
This liquid solution is designed to create a vibrant rainbow patina on copper surfaces using a controlled electrochemical process. The result is a smooth, colorful finish with shifting tones that range across the full spectrum, making every piece unique.
The solution is an alkaline chemical liquid and is used with a very low electrical current. During the process, a copper sheet is used as the anode, while the copper object you want to color is used as the cathode. When current is applied under the right conditions, the surface develops a vivid rainbow patina.
To use this product correctly, you will need:
- An adjustable power supply capable of delivering a very low voltage
- A glass beaker or heat-resistant glass container (do not use metal)
- An electric stove or heating plate to warm the solution
- A thermometer for liquids
The solution must be heated to the correct working temperature and used with a low voltage, typically between 0.1 V and 0.5 V. Precise control of voltage, temperature, and timing is essential for achieving consistent and beautiful color effects. This product is intended for users who are comfortable working with basic electrochemical setups.
A full, step-by-step demonstration is available on our YouTube channel, where you can see the complete setup, temperature control, voltage settings, and coloring process.
