 With weathering copper, brass and bronze will first turn a rich red bronze color and eventually progress to a green or blue green/turquoise color.
-
-
-
 This coloration is called PATINA which is actually a thin layer of oxidation on the surface or the metal.
-
-
- The distinctive green color of aged copper is also called VERDIGRIS. The most famous example of this is the Statue of Liberty. Natural patinas acquired over time are deeper, richer and more durable color. Copper roofs may last many hundreds of years.
-
- It is possible to speed up the patina process using COMMERCIAL CHEMICAL SOLUTIONS. Bottled patina formulas are available in the paint departments of some hardware stores as well as in the craft metal sections of hobby and craft supply stores.
- Caution should be used with these chemical solutions. They can be corrosive and must be used in a well ventilated area with gloves and eye protection. Carefully follow the manufacturer's instuctions.
-
- A Google search will turn up many HOME-MADE PATINA FORMULAS and TECHNIQUES. These formulas range from simple and quick to complicated and slow. An example of a quick technique is to seal your copper or brass object in a plastic bag with freshly hard boiled egg that has been cut in half. The sulfur from the egg will age or 'tarnish' the metal. Other techniques use amonia, salt or bleach. Remember: household chemicals can also require caution, adequate ventilation, gloves and eye protection. Mixing household chemicals can give off toxic gasses.
