age
The Bronze Age is a historical period that was characterized by the use of bronze, and in some areas proto-writing, and other early features of urban civilization. The Bronze Age is the second principal period of the three-age Stone-Bronze-Iron system, as proposed in modern times by Christian Jürgensen Thomsen, for classifying and studying ancient societies.
An ancient civilization is defined to be in the Bronze Age either by producing bronze by smelting its own copper and alloying with tin, arsenic, or other metals, or by trading for bronze from production areas elsewhere. Bronze itself is harder and more durable than other metals available at the time, allowing Bronze Age civilizations to gain a technological advantage.
Whilst terrestrial iron is naturally abundant, its high melting point of 1,538 °C (2,800 °F) placed it out of reach of common use until the end of the second millennium BC. Tin's low melting point of 231.9 °C (449.4 °F) and copper's relatively moderate melting point of 1,085 °C (1,985 °F) placed them within the capabilities of the Neolithic pottery kilns, which date back to 6000 BC and were able to produce temperatures greater than 900 °C (1,650 °F). Copper-tin ores are rare, as reflected in the fact that there were no tin bronzes in Western Asia before trading in bronze began in the third millennium BC. Worldwide, the Bronze Age generally followed the Neolithic period, with the Chalcolithic serving as a transition. Although the Iron Age generally followed the Bronze Age, in some areas (such as Sub-Saharan Africa), the Iron Age began as early as 2500 BC.Bronze Age cultures differed in their development of the first writing. According to archaeological evidence, cultures in Mesopotamia (cuneiform script) and Egypt (hieroglyphs) developed the earliest practical writing systems.
