Which risk increases when a bronze sword's tin content is excessively high during its initial casting?

💡 Explanation

When a bronze sword has excessively high tin content, tin-rich phases precipitate because tin has limited solubility in solid copper, increasing brittleness upon cooling. Therefore the sword becomes more brittle, rather than experiencing delayed corrrosion, decreased hardness, or having an elevated melting point, all of which require different alloy properties.
