A Little Bit Furnace Of History

Since the discovery of the earths minerals, we have been able to extract and build through Metalcasting. These heroic "Soldiers of the World" have made it possible for us to build an easier lifesyle. Without these brave individuals who create, invent, and design useful equipment we need in which to maintain every aspect of our lives.

Through their intelligence and expertise we have the ability to build office buildings to work from, homes to live in, schools to teach our children, movie theaters to watch movies, auditoriums and arenas to see concerts or plays. Even football stadiums to root for our favorite teams. They build the equipment we need to harvest our crops to feed our families and friends, as well as planes, trains and automobiles for transportation. They have made the value of our world increase more since World War II than it has in the past 3000 years! Molten metal has been used for many thousands of years to form and create various metal objects, equipment, jewelry, etc. Take a look at this little bit of history!


Catoctin Furnace

Thomas Baker and Roger Johnson constructed the Catoctin Furnace to produce pig iron. In 1776, the production of pig iron began. The fuel for the furnace was initially charcoal and the Catoctin forest provided the fuel for the furnace until 1873. Then the furnace was converted from charcoal fuel to coal. Simple machinery for James Rumsey's steamboat was made at the Catoctin Furnace Iron Works in the 1780's. Iron produced at the Catoctin Furnace during Jacob Kunkel's ownership was used to make the plates on the famous Civil War vessel, the Monitor.

The stack was filled with a layer of charcoal, a layer of limestone, and a layer of iron ore. Transportation of the iron ore to the furnace from the mines was by way of ore dump cars whose contents were dumped directly into the stack of the furnace. A charcoal iron furnace was a community of many skills. After changing hands several times, the Catoctin Iron Furnace was blown out for the last time in February 1903.

Cornwall Iron Furnace

Early America ’s industrial heritage comes alive at this completely preserved mid-19th century ironmaking complex, in blast from 1742 to 1883. The massive stone furnace, steam-powered air-blast machinery, and several related buildings survive intact. Primarily a producer of pig iron and domestic products, Cornwall Iron Furnace cast cannon barrels for the American Revolution.

Hopewell Furnace

Hopewell Furnace tells a fascinating story. Built by patriot Mark Bird, the furnace operated from 1771 to 1883. While its most profitable items were stoves, the furnace cast many other objects such as kettles, machinery and grates. During the Revolutionary War Hopewell supplied cannon, shot and shell for patriot forces. The furnace reached its peak between 1820 and 1840, then gradually was made obsolete by more efficient processes.
