Which outcome happened when early Mesopotamian bronze founders exceeded safe copper-arsenic alloy ratios?

💡 Explanation

When arsenic ratios exceeded safe limits during casting, high arsenic vapor emission occurred because arsenic readily vaporizes at casting temperatures, posing a significant inhalation hazard to metalworkers. Therefore arsenic vapor toxicity increased danger to workers, rather than casting flaws, increased strength, or increased ductility, requiring more refined process control.
