subject: The Creativity Behind A Bronze Sculpture [print this page] Pass by a statue in the park, and odds are that it's a bronze sculpture, which rank among the most common of cast metal works because of a naturally occurring trait that makes it much more convenient to fashion than many other materials. Bronze alloys expand a little prior to being set, and this helps to ensure that even the finest details of a mold are filled.
Moreover, bronze sculptures are strong while not being brittle, a quality known as ductibility, so that works may be fashioned that depict actions performed mid-sequence, as if frozen in time, such as leaps and flights, simply because the necessary supports require will smaller and thus less obvious (that is, visually intrusive) cross-sections.
Few examples from antiquity exist comparable to those sculpted of stone and ceramics due to the precious nature of the metal. In times of war, such art was simply melted down for arms, or victorious conquerors melting them down for recasting and to create new statues.
Few bronze statues survived from ancient times, and those which do are often not in good condition. The originals on display in museums have been painstakingly restored to a quality suitable enough for exhibition but even the naked eye can still easily discern traces of wear and tear.
Modern-day works are normally some ninety percent cooper and ten percent tin, though in ages past other components figured into the alloy, elements like phosphorus and manganese and aluminum and silicon. But reactive chemicals are frequently added these days in order to obtain novel effects such as a marble-like luster.
These kinds of corrosive materials are applied after final polishing to be able to form a patina or film, establishing for the sculptor a degree of control over the color and finish. As could be imagined, working successfully with bronze requires a high degree of technical skill.
