← HistoryWhich consequence arose during early Bronze Age casting when molds lacked sufficient venting?
A)Increased tensile strength of bronze
B)Porosity defects weaken the casting✓
C)Faster crucible cooling occurs
D)Elevated copper oxidation resistance
💡 Explanation
Air entrapment leads to porosity defects reducing structural integrity because trapped gases can't escape through inadequate vents during solidification, thus the casting becomes flawed, rather than stronger, cooling faster, or oxidation resistant, which improper venting does not directly influence.
