Short title: Architectural wrought-iron, ancient and modern : a compilation of examples from various sources of German, Swiss, Italian, French, English and American iron work from Mediaeval times down to the present day
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 .
For example, of the three forms of iron (wrought iron, steel, and soft), the forms which were exported were of the wrought iron (containing a small percentage of uniformly distributed slag material) and steel (carbonised iron) categories, as pure iron is too soft to function like wrought or steel iron.

The use of wrought iron allowed Tijou to work in more three dimensionality than seen before in other iron work. [ 9 ] Many works by Tijou were gilded . It is possible that a portrait of Jean Tijou appears at the bottom of the title page of a book entitled A New Book of Drawings Invented and Designed [sic] by John Tijou , [ 3 ] in 1693.
There are two main types of ironwork: wrought iron and cast iron. While the use of iron dates as far back as 4000 BC, it was the Hittites who first knew how to extract it (see iron ore) and develop weapons. Use of iron was mainly utilitarian until the Middle Ages; it became widely used for decoration in the period between the 16th and 19th century.
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.
By 1970, through the Cold War buildup, iron worker wages peaked at $44.80 (2010) ($7.97). Then, following the 1965 new immigration policy and the start of the fourth great migration wave, [ 5 ] wages fell 10% to $40.38 (2010) by 1980 ($15.26), and fell another 20% to $29.90 (2010) per hour ($20.88) by 1990, comparable to the 1950s wage rate.
