Wrought iron is an iron alloy with a very low carbon content (less than 0.05%) in contrast to that of cast iron (2.1% to 4.5%). It is a semi-fused mass of iron with fibrous slag inclusions (up to 2% by weight), which give it a wood-like "grain" that is visible when it is etched, rusted, or bent to failure.
An iron railing is a fence made of iron. This may either be wrought iron, which is ductile and durable and may be hammered into elaborate shapes when hot, or the cheaper cast iron, which is of low ductility and quite brittle. Cast iron can also produce complicated shapes, but these are created through the use of moulds of compressed sand rather ...
In the era of commercial wrought iron, blooms were slag-riddled iron castings poured in a bloomery before being worked into wrought iron. In the era of commercial steel, blooms are intermediate-stage pieces of steel produced by a first pass of rolling (in a blooming mill) that works the ingots down to a smaller cross-sectional area, but still greater than 36 in 2 (230 cm 2).
