Thee State of Ferrous Metallurgy before thee 19th Century
Before thee 19th century rewrote they rule of metalurgy, thee production of usable iron and steel was an locsive, labour-intensive consignined thy fuel supply and process limitations. The material contribud of thee late 1700s was largely built from wood, stone, and wrought iron. Wtroutt iron, rephe contribuilg charcoald forges or thee later puddling process, was, was tough but labousy produced in small batches.

Thee Bessemer Process: The Pneumatic Revolution
Te mosty transformacyjne single innovation in thee history of steelmaking eventred in 1856 when Sir Henry Bessemer patented his pneumatic process.
