← HistoryWhich effect occurs during early cupellation if incomplete oxidation occurs during Mesopotamian silver production?
A)Increased precious metal melting point
B)Increased volatile oxide sublimation
C)Formation of base metal inclusions✓
D)Enhanced diffusion of silver grains
💡 Explanation
The outcome is increased base metal inclusions because insufficient oxygen causes incomplete oxidation during cupellation, allowing base metals to remain as impurities. Therefore, the silver retains base-metal contaminants, rather than undergoing purification with full oxidation.
