- 18th centuryModern puddling was one of several processes developed in the second half of the 18th century in Great Britain for producing bar iron from pig iron without the use of charcoal. It gradually replaced the earlier charcoal-fueled process, conducted in a finery forge.

Puddling is the process of converting pig iron to bar (wrought) iron in a coal fired reverberatory furnace. It was developed in England during the 1780s. The molten pig iron was stirred in a reverberatory furnace, in an oxidizing environment to burn the carbon, resulting in wrought iron. It was one of the most … See more

Puddlers, Shinglers & Rollers: the Story of Malleable Iron
See more on culturenlmuseums.co.ukCast iron is made in a blast furnace, from which molten iron is cast in moulds. The resulting iron has a high carbon content and crystaline structure that makes it very hard but also brittle, too brittle to work with a hammer or use in structures that need to flex. From the late 1400s onwards malleable iron was made in a two-stage pr…- Estimated Reading Time: 10 mins
Throughout most of the 19th century, the process of choice in the west for producing wrought iron and steel was “puddling” of cast iron. A major development of the process, “wet puddling”, became wide-spread commercially beginning in 1830.
