Which risk during Ur III bronze axe production increased because furnace internal volume became larger?

💡 Explanation

Alloy segregation increased with furnace size due to slower cooling preventing complete mixing via convection; therefore, composition control decreased, rather than improved hardness, mold stability problems, or changes in crystalline structure within the solidified bronze during early casting techniques.
