Which outcome resulted from the use of reverberatory furnaces during the 18th-century Industrial Revolution?

💡 Explanation

When reverberatory furnaces were used, indirect heating of iron ore occurred because the fuel was burned in a separate chamber, thus achieving higher temperatures, improving carbon removal, and producing stronger cast iron. Therefore stronger iron was produced, rather than steam engines, textiles or power grids which arose from different innovations.
