Blast Furnace
3InfrastructureInfrastructure
Description
Larger furnaces than the shaft furnace, driven by higher heat and stronger air blasts to smelt iron. Capable of yielding cast iron in quantity, they transformed metallurgy, though the output often required further refining in a finery forge.
Their metal output greatly aided the rapid equipment of armies.
