In ancient bronze casting using the lost-wax technique, which consequence would result from inadequate crucible preheating?

💡 Explanation

Incomplete crucible preheating can drop the melt temperature significantly because quenching accelerates heat transfer; therefore premature solidification occurs. Incomplete mold filling occurs, rather than hydrogen defects or alloy segregation; metal would have higher fluidity at optimal temperature, helping it fill small cavities.
