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.

Petrographic & Geological Characteristics

Fibrous puddled iron (reverberatory furnace refining), high slag inclusions, negligible carbon.

Lime Mortar & Breathability Compatibility

Fix in stone sockets with pure molten lead; puddled iron resists laminating rust far better than modern mild steel.

Provenance & Historical Sourcing

Salvaged genuine puddled iron rolled and reworked for conservation.

Condition Report & Patina

Tested for absence of modern carbon-steel impurities; pure puddled grain.
