The first American smelt of Anthracite Pig Iron was performed July 4, 1840 by principal-partners David Thomas, Josiah White and Erskine Hazard at their Lehigh Crane Iron Works in their first hot blast furnace along Catasauqua Creek aided by Samuel Thomas and the employees of the LCIW, in what became Catasauqua in Northampton County, Pennsylvania. The technology enabled industries the chance to produce cast iron sufficient to demand and eventually adapt production to also feed the demand to generate wrought iron and steel. These useful materials are achieved by adding additional processing — by taking pig iron
