After some problems with the blast furnace in 1868, the mining and smelting ran well, producing pig iron until 1872, when a change over to a hot blast ruined the furnace and all activity ended. Because the original plan was to produce quality, high-priced steel from the pig iron, this furnace was not competitive as solely a pig iron producer.
