Anthracite iron combined those experiments and the new hot blast processing. In the United States, where the Lehigh Coal & Navigation Company (LC&N) had begun shipping anthracite to Philadelphia in 1820 because the principles could not obtain sufficient fuels for their iron works at "the 'Falls of the Schuylkill' "—so had built the Lehigh Canal and taken over the works of the haphazard Lehigh Coal Mine Company—by the late 1820s having established works that were running smoothly, after building America's second operating railroad in 1827, they'd great interest in exploiting the great anthracite deposits of Schuylkill County for ironmaking, which mills foundries
Anthracite iron of 1839. In the meantime, Pioneer Furnace, in Pottsville, was blown in using anthracite fuel in 1839. It was built by William Lyman obtained the aid of a Welsh emigrant, Benjamin Perry, who was familiar with Neilson's process and the Yniscedwyn works, for the blowing-in. The furnace ran for three months on anthracite alone and fulfilled the conditions to win the $5,000 prize. In the design of Pioneer Furnace, Lyman had also been assisted by David Thomas, who had arrived in the United States in May 1839. Thomas was engaged by the LC&N to set up the Lehigh Crane Iron
