Which consequence results from localized overheating in early iron production bloomery furnaces?

💡 Explanation

When temperatures spike locally, increased carburization occurs because iron absorbs more carbon from charcoal, converting to high-carbon steel or cast iron. Therefore elevated carbon absorption results, rather than increased slag, reduced reduction, or wall collapse which involve distinct thermal and chemical mechanisms.
