Which risk increases when bronze-age metal casters rapidly cool a freshly cast bronze axe head?

💡 Explanation

When rapidly cooled, thermal stress exceeding the material's tensile strength concentrates because differential contraction causes cracking, increasing brittleness. Therefore, increased brittleness results, rather than reduced hardness, decreased ductility, or elevated corrosion, which arise from different metallurgical processes.
