Learn about the Bluff Furnace, Chattanooga's first heavy industrial site. This blast furnace was built in the 1850s by ironmaster Robert Cravens. The furnace produced raw iron from local iron ore and was originally fueled with charcoal. In May 1860, it was converted to a coke fueled furnace-the first in the South. Nick Honerkamp, a professor of archaeology at UTC, will share the story of Bluff Furnace and tell us about Chattanooga's industrial history, from its early years to being named the United States' most polluted city in 1969.
