Thus, really few big examples in bronze are available from ancient times, and of these most aren’t in good condition. Indeed, most works exhibited in museums, while still full of the evidence of wear and tear, have been painstakingly restored to a quality suitable for display. Working successfully with bronze usually requires a high level of skill, and a number of distinct casting processes may need to be employed, such as lost-wax casting and also the related modern-day technique of investment casting. Other methods include sand casting and centrifugal casting. After final polishing, corrosive materials might be applied to bronze works in order to form a patina or film produced by oxidation or some other chemical method and establish some control over the color and finish. For example, reactive chemicals may be applied to produce a novel marble-like appearance. About the Author: This is better than blindly paying the contractor, what ever he asks for.
