Anthracite iron and nail factory), had determined how to burn anthracite in iron working processing furnaces during the War of 1812, but its use in smelting operations was hit or miss, dependent upon the material packing geometries of any particular charging load in a cold blast furnace. The earlier development of coking of bituminous coal, as well anthracite coke enabled the smelting of iron using local coal sources with cold blast air in blast furnaces after the latter 1830s allowed the production of the vast quantities of iron that built the fundamental infrastructure of the early North American Industrial Revolution — which
Anthracite iron States, in the principal control and supervision of Ironmaster David Thomas who had begun experimenting with attempts to use locally available Wales anthracite deposits as early as 1820 soon after he became in charge at Yniscedewin Iron Works in Wales. About this 1837-38 timeframe experiments were also being made in Pennsylvania near Port Carbon, and in Mauch Chunk, but with overall better success than in Wales. White, Hazard and the LC&N Co. had begun systematic experiments to smelt using anthracite in two furnaces in Mauch Chunk in 1832-1837 with intermittent but sporadically improved successes using cold blast processes with two
