Which constraint limited blade length during the Bronze Age sword manufacture process?

💡 Explanation

During the Bronze Age, crucible size impacted the volume molten metal available limiting the size items could be consistently cast because it's hard to ensure that the entire item is created from a single smelt. Therefore, crucible size constrains maximum blade length, more so than material degradation, brittleness or forge limitations during that era.
