INFORMATION ABOUT BRONZEBronze is a metal alloy about 90% copper, this material oxidizes (tarnishes) when exposed to chemicals that are on human hands, in the atmosphere and in water. The actual bronze raw metal is a beige color when pressure blasted with abrasives to a clean surface. The finished color, which varies on bronzes is called a patina. This is a controlled oxidizing process. It is accomplished by heating the metal and then brushing or spraying a concentrated mixture of water and chemicals to the surface. Different chemicals give variation in color and a broad range of color values can be achieved with temperature, chemical concentration and application techniques.
