Which risk increased during the Bronze Age when casting intricate figurines using the lost-wax process?

💡 Explanation

When casting intricate bronze figurines with the lost-wax process, core shift becomes a significant problem because the ceramic core supporting the molten metal can move during pouring or cooling due to pressure differences, leading to uneven metal distribution. Therefore, material loss results from core shifting, rather than embrittlement, oxidation, or segregation,which arise from compositional/environmental effects.
