Blast furnace. Catoctin blast furnace at Thurmont, Maryland, USA. It originally dates from 1714, but was rebuilt in the late 1800s. This photograph (from around 1900) is from the Albert T. Keller collection of the American Iron and Steel Institute. The collection consists of historical photographs of blast furnaces used in the iron and steel industry. A blast furnace is where iron ore is heated to high temperatures in the presence of oxygen, with the carbon content controlled to produce types of steel (an alloy of iron and carbon).
