In ancient bronze foundries, which outcome resulted when tin was excessively volatile during crucible melts?

💡 Explanation

Metal embrittlement risked component failure because tin depletion during melting skewed the intended alloy ratio via selective evaporation, therefore resulting brittle grain boundaries rather than uniformly ductile bronze because alternative ratios yield stronger ductile components if precisely controlled.
