History

Which consequence limits the dimensions of early bronze tools fabricated via the lost-wax casting process?

A)Rapid mold sulfur oxidation
B)Ceramic mold thermal shock
C)Inadequate crucible carbon reduction
D)Shrinkage-induced crack propagation

💡 Explanation

Shrinkage-induced crack propagation occurs because volumetric contraction during bronze solidification causes stresses exceeding the mold's tensile strength, leading to cracking and dimensional limits, therefore setting tool size limits rather than the other listed material-specific problems.
