jan 1, 2100 BC - The Bronze Age was a time of extensive use of metals and of developing trade networks (See Tin sources and trade in ancient times). A 2013 report suggests that the earliest tin-alloy bronze dates to the mid-5th millennium BC in a Vinča culture site in Pločnik (Serbia), although the civilization is not conventionally considered part of the Bronze Age. The dating of the foil has been disputed.
