A Short History of Steel and the Bessemer Process

Blast furnaces were first developed by the Chinese in the 6th century B.C., but they were more widely used in Europe during the Middle Ages and increased the production of cast iron. At very high temperatures, iron begins to absorb carbon, which lowers the melting point of the metal, resulting in cast iron (2.5 percent to 4.5 percent carbon).
