Which risk increases when arsenical bronze ingots used for Mesopotamia tools are repeatedly reheated during forging?

💡 Explanation

When arsenical bronze is repeatedly reheated, increased sublimation occurs accelerating release of highly poisonous arsenic fumes affecting the smiths. Therefore arsenic fume inhalation risk increases, rather than tin oxidation, cobalt embrittlement, or lead segragation which require entirely different alloy compositions and failure mechanisms.
