What is Bronze?
Human beings have been working with bronze for over 3,000 years in various parts of the world. Bronze is a metal alloy produced by blending copper and tin in various amounts. Additional elements such as manganese, lead, and phosphorous are added when specific properties of bronze are desired. For example, phosphorous is added to harden the bronze material while lead is included to make the bronze easier to cast.
One of the more unique properties of bronze is the natural patina that may form. Patina may turn the bronze a dark or dull color. Patina is actively encouraged with most bronze because it provides a protective layer, preventing oxidation below the surface of the bronze. While most bronze products are often coated with a thin layer of lacquer to protect the metal, exposure to the elements over time will often lead to corrosion. If a bronze piece starts to corrode, it can be professionally treated to restore the original appearance.
