Anthracite iron century. Research into the smelting of iron using anthracite coal (without coking it first) began in the 1820s in Wales by Thomas, experiments in France, most notably by Gueymard and Robin at Vizille in 1827, and in the 1830s in Pottsville & Mauch Chunk, Pennsylvania. Early attempts tried to gradually substitute anthracite for other fuels, such as coke or charcoal, but all failed due to the use of cold blast techniques, which generated insufficient heat to keep the anthracite in regenerative combustion. In the same time-frame, Thomas had also continued experimenting with mixes of Anthracite and other fuels, before he
Anthracite February 1808, by Judge Jesse Fell in Wilkes-Barre, Pennsylvania, on an open grate in a fireplace. Anthracite differs from wood in that it needs a draft from the bottom, and Judge Fell proved with his grate design that it was a viable heating fuel. In spring 1808, John and Abijah Smith shipped the first commercially mined load of anthracite down the Susquehanna River from Plymouth, Pennsylvania, marking the birth of commercial anthracite mining in the United States. From that first mine, production rose to an all-time high of over 100 million tons in 1917. Anthracite usage was inhibited by the
