Inspired both by Geisenhainer and Crane (whose success was closely followed by the LC&N), experiments in the US continued. Baughman, Guiteau and Company used an old furnace near Mauch Chunk to produce some anthracite iron during late 1837. They built another experimental furnace nearby, which was worked for about two months during fall and winter 1838 and for some time in 1839, but mechanical deficiencies led them to abandon the furnace at the end
