Puddling

The puddling is an old process of refining of the cast iron consisting to decarbonize it (to brew) in a furnace using Scorie S oxidizing to obtain puddled iron , more flexible than of the cast iron.

This process is developed by the English Henry Cort in 1784. The cast iron is refined at very high temperature in a specific furnace. The puddler, the workman in charge of the operation, is then charged to brew ( puddling ) this cast iron in fusion using a long hook called old-fashioned. The material can then be hammered, rolled or forged.

The arches of the Station of the East and the Eiffel Tower in Paris are thus made out of puddled iron.
