BLS WORKING PAPERS

Useful iron products in 1870 took three general forms pig iron, wrought iron, and steel. Pig iron has 2.5% to 6% carbon and is the easiest to make from most iron ore. It is brittle, meaning it can break when other materials might bend. It can be cast into molds to make, for example, stoves or pots, and so may be cast iron. When pig iron is
