===Bloomery process=== Wrought iron was originally produced by a variety of smelting processes, all described today as `bloomeries`. Different forms of bloomery were used at different places and times. The bloomery was charged with charcoal and iron ore and then lit. Air was blown in through a tuyere to heat the bloomery to a temperature somewha.....

Ironwork that is drawn and worked into elaborate shapes on an anvil while hot. It is not as hard or brittle as cast iron and is used for objects such as grilles, screens, garden furniture, candle-holders and andirons. Wrought iron has been made since ancient times.

A form of iron containing little carbon, but having then layers of slag between fibres of metallic iron. It is resistant to corrosion, and is tough, rather than brittle. Used to make gates, railings, ironmongery and nails. Common in buildings built before the 1930s, but now difficult to obtain, and expensive.Related Words: Ironmongery

Iron that is almost pure (less than 0.15% carbon). Can be shaped and forge welded with ease, but is soft and does not harden in the same way as Steel. Wrought Iron is rarely seen in molten from as it has a high melting point and there is no advantage in melting it as part of a process. Part of the properties of Wrought Iron are attributed to the Sl...
