I was just checking the maps and I don’t get it. Copper could be found in the Mideast. Tin not so. In fact, in the Bronze Age, the nearest tin available was in Spain (but up in Galicia). Now the Bronze Age got going around 3000 BC. There are n o records of the Phoenicians getting up that far at that time, in fact I don’t think they were even really up and running as city states. So who got the tin? The Minoans? Or was it that another alloy was used to make bronze stuff?
The sources of tin in the early Bronze Age aren't exactly known, and has been the subject of much debate. It's likely that there were some tin sources in the near east that were depleted early on, but have not been discovered. There is some more recent (1994) archaeological investigations that indicate a source of tin in the Central Taurus Mountains in Turkey at Kestel/Göltepe. (see Tin Processing at Göltepe, an Early Bronze Age Site in Anatolia, Yener & Vandiver)
Arsenic was widely used to make bronze in the early Bronze Age, and arsenical bronze continued to be used in some areas quite late. Arsenic was more readily available than tin. Arsenical bronze is more ductile than tin bronze, but doesn't cast as well. It eventually fell out of favor, particularly for cast weapons, but some places like Egypt kept using it for artwork. As you might expect, arsenic vapors from the smelting process also can cause neurological damage. It's suspected that the reason Hephaestus, the Greek god of the forge is depicted as lame dates back to the practice of using arsenical bronze and its effects on the bronzesmiths.
