Copper is a metal that has a rich, warm brownish-pink color. It's considered a base metal because it changes color or oxidizes when exposed to air, compared to precious metals such as gold, platinum and sterling silver. This means a mirror-polished copper bracelet that's almost pinkish in tone will eventually tarnish or develop a patina over time. You can speed up this process and even create other colors of patina by using some simple techniques and household supplies.
Things You'll Need
- Glass jar with lid
- Scrub brush
- Dish soap
- Liver of sulfur in lump form
- 1 cup hot water
- Bowl or cup large enough to hold your copper
- Wooden spoon for stirring
Clean the copper using the scrub brush and soap. Dry thoroughly.
Place a pea-sized chunk of liver of sulfur in a bowl. Pour in hot water to dissolve the liver of sulfur. Stir with the wooden spoon.
Put the copper into the liver of sulfur for a few seconds to 30 minutes, depending on how dark you want the metal to get.
Take the copper out of the liver of sulfur. Rinse and dry.
Put about 1/2 cup oatmeal in the glass jar with the vinegar. The oatmeal is optional; its texture will leave a pattern on the metal.
Bury your copper in the oatmeal-vinegar solution. Put the lid on the jar. Shake the jar if desired.
Leave it sit for up to one week until your copper has turned the desired shade of blue or green. Do not rinse.
Tips & Warnings
- When making jewelry, applying a patina to metal should be the last step once all soldering is complete.
