This process for producing steel revolutionized the entire industry, because it allowed for cheap and fast production of large quantities. Patented in 1855, it is named for its discoverer.

The process is called the Bessemer process, named after its inventor, Henry Bessemer. This process involved blowing air through molten iron to remove impurities and carbon, resulting in a much stronger and more durable steel product. The Bessemer process played a crucial role in the industrial revolution and greatly increased the availability and affordability of steel for construction, manufacturing, and other industries.
