Mix equal parts of salt and vinegar together in a bowl before adding the copper to the bowl. Allow it to sit for 30 minutes, and then remove the copper from the bowl and set on a paper towel. The copper must air dry for the process to work. Once the copper has achieved the desired aging level, seal it in a lacquer or wax.
Copper can also be aged quickly using rapid fixer, a solution commonly found at camera stores. To complete the process, the rapid fix solution, latex gloves, a sealant, a plastic tray and paper towels are needed. Clean the copper before adding it to the rapid fix solution. For every tablespoon of rapid fix solution used, add 2 tablespoons of water. Place the copper into the solution for 10 minutes before rinsing it under cool water. Allow it to air dry before coating it in a sealant.Learn more about Precious Metals & Gems
