Which risk increased in early Mesopotamian bronze metallurgy because of repeated crucible firings?

💡 Explanation

Increased firing cycles induced grain growth via recrystallization; therefore, metal becomes brittle, leading to early fractures of casted ingots and tools, rather than maintaining finer grain structures for improved toughness
