Which outcome results when incorrectly hardened bloomery iron is rapidly cooled?

💡 Explanation

When bloomery iron is rapidly cooled after hardening, differential contraction creates high thermal stresses because the material lacks uniform composition, leading to crack formation. Therefore, quenching cracks result, rather than ductility, corrosion resistance, or weldability, which involve different microstructural or surface modifications.
