Which outcome occurred when ancient Mesopotamian bronzesmiths cast large-format objects with high tin content?

💡 Explanation

When bronze with a higher tin content cools, allotropic transformation causes 'tin pest' because, at lower temperatures, the tin transforms into powdery allotropes which leads to disintegration. Therefore, structural failure risk increases, rather than strengthening, easier casting, or corrosion resistance, properties needing alternative composition control.
