Did the discovery of these new metals give a clear advantage for one civilization over others? Did overall quality of life increase with these new discoveries as well? What happened to just day to day when these new metals were put into everyday production? Was there even enough for more than a military use? How drastically did the military change? Was it just updates of their old equipment in the metals, or were knew weapons made specifically for each new discovery of metals?

I'm not exactly sure which new metal was formed first, but I assume that one and the next would be the biggest leaps in technology. Also the best answers to my questions. I figure there will be dispute/lack of information on who did it first just because of the length of time between then and now. So maybe something along the lines of just explaining what happend in Rome or another well populated area.

I'm sorry if I couldn't narrow it done enough to a more specific region/topic.
