Historical & Geological Context

Puddled iron (fer puddlé) is genuine wrought iron refined by hand in puddling furnaces before the advent of the Bessemer process. Containing microscopic fibers of iron silicate slag, it possesses exceptional ductility, welds seamlessly at the anvil fire, and resists atmospheric corrosion far better than modern steel. Mandatory for restoring 18th- and 19th-century monumental gates and railings.
