  • Bronze, an alloy traditionally composed of copper and tin. Modern bronzes are typically 88% copper and about 12% tin. Bronze has special historical significance and is still widely used today. The earliest bronze objects were made around 4500 BC, but the use of bronze in objects did not become common until much later, in the Bronze Age of the 2nd millennium BC. The proportions of copper and tin vary widely (from 67% to 95% copper in extant artefacts), however, in Europe by the Middle Ages, certain proportions were known to produce specific properties. An alloy described in an 11th-century Greek manuscript in the Library of San Marco in Venice is cited as a ratio of one pound of copper to two ounces of tin (8 to 1), about the ratio that was later used in bronze gunmetal. Some modern bronzes contain no tin at all, replacing it with other metals such as aluminium, manganese, or even zinc.
