The Importance of Copper for Modern Life
Copper can turn green due to a process called oxidation, which occurs when copper reacts with oxygen in the air and forms copper oxide. This green layer, also known as patina, can be prevented with the following steps: 1. Keep copper dry: Moisture can speed up the oxidation process and cause copper to turn green faster. Dry your copper items thoroughly after use. 2. Apply a protective coating: Wax, oil, or lacquer can protect copper from air exposure and prevent oxidation. Apply a thin coat of protective coating to your copper items regularly. 3. Store copper properly: Store copper in a dry and cool place, away from direct sunlight or moisture. Wrap or cover your copper items with a cloth or paper towel to prevent scratches or dust accumulation. 4. Clean copper regularly: Regular cleaning can help prevent oxidation and keep copper shiny. Use a soft cloth and mild soap and water to clean copper items, and dry them thoroughly afterwards. By following these steps, you can help keep your copper items from turning green and maintain their shine and beauty over time copper reclamation copper scrap drop-off
