This new technology first appeared in the Middle East between 3500 and 3000 B.C. and expanded throughout the whole European territory from the second half of the 3rd millennium on. The technique most probably results from research aiming at improving the copper quality by mixing it up with other metals. Bronze is an alloy of copper and tin; its hardness qualities (resistance to pressure), its resilient properties (resistance to shocks) as well as its casting possibilities are far greater than those of copper. At the Archaeological Site you’ll discover two smelting techniques: lost wax and bivalve mould.
