Bronze

 

Bronze is a metal alloy consisting primarily of copper, usually with tin as the main additive.

It is hard and brittle, and it was particularly significant in antiquity, so much so that the Bronze Age was named after the metal.

However, since “bronze” is a somewhat imprecise term, and historical pieces have variable compositions, in particular with an unclear boundary with brass, modern museum and scholarly descriptions of older objects increasingly use the more cautious and inclusive term “copper alloy” instead.

The discovery of bronze enabled people to create metal objects which were better than previously possible.

Tools, weapons, armor, and various building materials, like decorative tiles, made of bronze were harder and more durable than their stone and copper predecessors.

Initially bronze was made out of copper and arsenic to form arsenic bronze.

It was only later that tin was used, becoming the sole type of bronze in the late 3rd millennium BC.

Tin bronze was superior to arsenic bronze in that the alloying process itself could more easily be controlled and the alloy was stronger and easier to cast.

Also, unlike arsenic, tin is not toxic.

The earliest tin-alloy bronzes date to the late 4th millennium BC in Susa (Iran) and some ancient sites in China, Luristan (Iran) and Mesopotamia (Iraq).

Copper and tin ores are rarely found together (exceptions include one ancient site in Thailand and one in Iran), so serious bronze work has always involved trade.

In Europe, the major source for tin was Great Britain’s deposits of ore in Cornwall, which were traded as far as Phoenicia in the Eastern Mediterranean.

Bronze was especially suitable for use in boat and ship fittings prior to the wide employment of stainless steel owing to its combination of toughness and resistance to salt water corrosion.

Bronze is still commonly used in ship propellers and submerged bearings.
