During the Bronze Age, which primary risk limited casting intricate designs using lost-wax technique?

💡 Explanation

During bronze casting via lost-wax, differential cooling rates create internal tensile stresses because thinner regions solidify faster than thicker ones causing shrinkage cracking. Therefore, solidification cracking limits intricate designs, instead of oxidation, which is mitigated by fluxes, grain growth, which depends on composition control, or rapid cooling which isn't typical or desired.
