Which outcome resulted from using coke rather than charcoal in 18th-century iron production?

A)Increased tensile strength achieved initially

B)Higher furnace temperatures became sustainable✓

C)Reduced slag formation due to purity

D)Elimination of sulfur-induced iron embrittlement

💡 Explanation

Higher furnace temperatures resulted due to the higher carbon content and energy density of coke, enabling more efficient smelting; blast furnaces leveraging the Boudouard reaction increased proportionally, therefore the answer is higher temperatures, rather than impurity changes.
