Question
History

Within early blast furnace design, which limitation results from decreased iron production in a bloomery furnace adapted without addressing algebraic stoichiometric ratios?

A)Over-oxidation dominates the reduction process
B)Liquidus temperature inhibits slag formation
C)Excess manganese increases material brittleness
D)Carbon monoxide prevents oxygen displacement

💡 Explanation

Insufficient charcoal lowers carbon monoxide levels, causing over-oxidation because oxygen then interacts with iron, forming iron oxides rather than metallic iron, and decreased yield results. Maintaining proper CO:O₂ ratios is critical, therefore incomplete reduction results rather than alternative effects at that phase.
