Not so, bronze didn t actually become common enough for the everyday citizen of Athens until well into the early Bronze Age. Even after the appearance of bronze, obsidian was still used a lot. Obsidian is a black rock that has almost a polished appearance even just after it has been broken. Obsidian was, however, harder to shape than bronze. The ability to shape combined with the luster of bronze made it a popular metal for jewelry .
Bronze is mostly copper combined with another element.
Elements that were used in making bronze were arsenic and later on tin was used, as the arsenic was actually poisonous. They had to be bought at an extremely high price, brought in from other distant countries . With bronze the first metal swords could be crafted though they were slightly brittle and used mostly for stabbing and not hacking. These swords were little more than long daggers. Later on iron would be introduced.
