Tin is an essential metal in the creation of tin-bronzes, and its acquisition was an important part of ancient cultures from the Bronze Age onward. Its use began in the Middle East and the Balkans around 3000 BC.
Bronze is an alloy consisting primarily of copper, commonly with about 12–12.5% tin and often with the addition of other metals (including aluminium, manganese, nickel, or zinc) and sometimes non-metals (such as phosphorus) or metalloids (such as arsenic or silicon).
A study in the journal Antiquity from 2013 reported the discovery of a tin bronze foil from the Pločnik archaeological site dated to c. 4650 BC, as well as 14 other artefacts from Serbia and Bulgaria dated to before 4000 BC, showed that early tin bronze was more common than previously thought and developed independently in Europe 1,500 years before the first tin bronze alloys in the Near East.
Tin mining began early in the Bronze Age, as bronze is a copper-tin alloy. Tin is a relatively rare element in the Earth's crust, with approximately 2 ppm (parts per million), compared to iron with 50,000 ppm.
There have been finds of tin slag on the floors of Bronze Age houses, [32] for example at Trevisker. Tin slag was found at Caerloges with a dagger of the Camerton-Snowhill type. In the Iron Age bronze continued to be used for ornaments though not for tools and weapons, so tin extraction seems to have continued. An ingot from Castle Dore is ...
In the Tarascan Empire, copper and bronze was used for chisels, punches, awls, tweezers, needles, axes, discs, and breastplates.

However, as conquest gained them metal working regions, the technology started to spread.

A 2013 report suggests that the earliest tin-alloy bronze was a foil dated to the mid-5th millennium BC from a Vinča culture site in Pločnik, Serbia, although this culture is not conventionally considered part of the Bronze Age; [3] however, the dating of the foil has been disputed. [4] [5]
