    • ‘The Bessemer process of steelmaking - which Carnegie was the first to use - produced vast quantities of hard, durable metal at low cost.’
    • ‘For example, in 1850 the steel making industry was drastically changed by the Bessemer process which burned out impurities in iron through the use of a blast furnace.’
    • ‘The Bessemer process, patented in 1855, made mild steel a cheap and superior rival for wrought and cast iron in some products.’
    • ‘The open-hearth process of steel-making allowed the operator a greater amount of control over materials used in the mills' heat than did the older Bessemer process.’
    • ‘The Basic Bessemer process is used a great deal on the Continent for making, from a very suitable pig iron, a cheap class of steel, e.g. ship plates, structural sections.’
