Which risk increased in ancient Mesopotamian ziggurats if the clay brick **vitrification** process failed to fully convert silica?

💡 Explanation

Decreased structural capacity occurs because incomplete vitrification prevents silica from forming a strong glass matrix, therefore the bricks are weaker mechanically rather than resisting weather damage or limiting thermal fatigue.
