THE STORY BEHIND THE PHOTOGRAPHS
People, places, and change.
An iron works in the Blackberry River valley
Beckley Furnace began operating in 1847 in East Canaan, within the town of North Canaan. It later belonged to Barnum & Richardson’s regional ironmaking enterprise. The furnace produced pig iron, the intermediate material used by the company’s foundries at Lime Rock to cast railroad car wheels. The stone stack was part of a larger working landscape that included charcoal storage, rail spurs, worker housing, waterpower equipment and buildings for charging the furnace and casting its output. [1] [2]
Air, fuel and molten metal
Charcoal supplied the fuel, while water-powered machinery forced air into the furnace. An oven used waste gas to heat that air before it entered, improving combustion. At the casting arch, workers drew off slag and then released molten iron into sand molds, where it hardened into the ingots known as pigs. The Friends of Beckley Furnace’s interpretation explains these steps through the surviving structure. The glasslike pieces in the accompanying photograph are displayed slag samples: a waste product that records the smelting process. [3] [5]
An altered survivor
The structure visible today reflects more than the original 1847 campaign. Preservation Connecticut records an 1896 rebuilding that increased the stack to forty feet high, with limestone walls, reinforcing iron and four arched openings. Much of the surrounding complex has disappeared. Reading the stack together with the remains of waterpower and material handling explains why a blast furnace cannot be understood as an isolated stone monument. It was one component in a coordinated industrial system. [2]
From production to preservation
Production continued through the winter of 1918–1919 and ceased in 1919. Buildings and equipment deteriorated, and material was removed for scrap during the Second World War. In 1946 engineer Charles Rufus Harte promoted state acquisition and preservation. Connecticut designated the site a state park and its official Industrial Monument; National Register recognition followed in 1978. The modern photographs record that preserved legacy, rather than a furnace still producing iron. [1]
