Benefits of copper
Copper is well loved for its durability and unique sheen. It makes a great material for weathervanes. Left untreated, copper will weather and change color. This weathering process protects the weathervane from corrosion and adds to its beauty. Because of copper's strength and durability, it is a great weathervane material.
The weathering process
Over time, copper will turn from its natural reddish brown color to a darker black-brown, and eventually will turn to a green patina. This oxidation process usually takes four to ten years to complete. If the weathered copper look is preferred, the weathervane can be treated with a copper sulfate acid for a quick patina finish. Both new and weathered copper weathervanes offer their own aesthetic appeal.
Caring for copper
Copper weathervanes require little maintenance. Because they have been lacquered, they can be cleaned with a soft cloth and soapy water. If a weathervane has been allowed to weather naturally or with assistance, there is a different way to clean it. A commercial copper polish is used in cleaning or a homemade polish can also work. A homemade polish is a mixture of salt, vinegar and lemon juice. When using a commercial copper polish, make sure to read all instructions before polishing the weathervane.
Copper weathervanes are functional and charming. They make a great addition to any rooftop. Because they are available in so many styles, there is a copper weathervane to fit anyone's decorative taste. Copper is the most popular material used in weathervanes for its beauty and natural weathering process. A copper weathervane is sure to continue to look good year after year.
