iron processing Britannica

Accelerating the conversion of pig iron to malleable iron was attempted by a number of inventors, but the most successful was the Englishman Henry Cort, who patented his puddling furnace in 1784. Cort used a coalfired reverberatory furnace to melt a charge of pig iron to which iron oxide was added to make a slag. Agitating the resultant puddle of metal caused carbon to be removed by oxidation (together with silicon, phosphorus,
