Bronze


Bronze is an alloy consisting primarily of copper, usually with tin as the main additive. It is hard and tough, and it was so significant in antiquity that the Bronze Age was named after the metal. However, historical pieces were often made interchangeably of brasses (copper and zinc), and bronzes with different compositions, so modern museum and scholarly descriptions of older objects increasingly use the more inclusive term “copper alloy” instead. Historically the term latten was used for such alloys.
