Steam Engines to a whole new level

These steam engines are running on coal, that's why coal production seems to be so grand these days. This is leading to a new development for stronger iron! A guy named Henry Cort figured out a way to make iron stronger! He invented the process of puddling! According to my research, coke, which is material derived from coal, was used to clean the impurities in crude iron. The outcome, high quality iron.
Below is a picture of a puddling furnace.
