This process allowed for cheap high quality, mass produced steel: Gossemat Portfixed Enlightenment Bessemer

The process you are referring to is the Bessemer process. This process, developed by Sir Henry Bessemer in the mid-19th century, revolutionized the production of steel by making it more efficient and cost-effective. The Bessemer process involves blowing air through molten iron to remove impurities and produce high-quality, mass-produced steel. This process allowed for the large-scale production of steel, which had a significant impact on industries such as construction, transportation, and manufacturing.
