The Franklin Institute, in 1830, offered a gold medal to the manufacturer of the greatest quantity of anthracite iron, and Nicholas Biddle and his associates offered a prize of $5,000 to the first individual to smelt a certain quantity of iron ore within a given time, using anthracite.

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
