Which phenomenon limited the size of castings when early metallurgists poured molten bronze for large statues?

💡 Explanation

Hot tearing posed a limit because tensile stresses developed during non-uniform cooling exceeded the cohesion of the solidifying bronze microstructure; therefore, the metal cracked, rather than maintaining structural integrity with larger statue dimensions.
