Cast iron development lagged in Europe because wrought iron was the desired product and the intermediate step of producing cast iron involved an expensive blast furnace and further refining of pig iron to cast iron, which then required a labor and capital intensive conversion to wrought iron.
The branding iron consisted of an iron rod with a simple symbol or mark which was heated in a fire. After the branding iron turned red-hot, the cowhand pressed the branding iron against the hide of the cow. The unique brand meant that cattle owned by multiple owners could then graze freely together on the commons or open range.

Steel is an alloy composed of between 0.2 and 2.0 percent carbon, with the balance being iron. From prehistory through the creation of the blast furnace, iron was produced from iron ore as wrought iron, 99.82–100 percent Fe, and the process of making steel involved adding carbon to iron, usually in a serendipitous manner, in the forge, or via the cementation process.
An ironworking industry likely evolved during the late Yayoi or the Kofun period, when iron weapons and armor became more common. However, the best archaeological evidence for early iron-working techniques in Japan dates to the Asuka period, after Buddhism had been introduced to the imperial court of the Yamato state.
Smithing is necessary to cut up and remove the trapped slag by reheating, softening the slag and then squeezing it out. On the other hand, refining is needed for the cast iron produced in the blast furnace. By re-melting the cast iron in an open hearth, the carbon is oxidized and removed from the iron. Liquid slag is formed and removed in this ...

Ironwork is any weapon, artwork, utensil, or architectural feature made of iron, especially one used for decoration. There are two main types of ironwork: wrought iron and cast iron.
