The ironmaking process resulted in by-products as well. This furnace produced a waste product called slag. This material is formed from other minerals present in iron ore, most notably silicon, and resembles glass. During the years of its operation this furnace produced an enormous amount of slag. The size of the slag heap across the river from the furnace was estimated at 900,000 cubic yards in 1920. Some of the slag was crushed and mixed with cement to make slag concrete. A number of buildings in New England were made with slag exported from this site. Slag was also used as a component in road surfacing, but it did not perform well in that application. Ultimately the slag was abandoned to the forest which has reclaimed the slag piles and made them all but invisible today.
Beckley Furnace has been designated an Industrial Monument by the State of Connecticut, the first site in the state to achieve
Please explore this remnant of northwestern Connecticut's industrial past. Interpretive signs have been placed near the significant remaining structures on the site to help you appreciate what once was here.
Furnaces such as this one were usually located on the side of a hill so that access to the top of the stack could be gained via a bridge from the hilltop.
The furnace is a stone tower with a central chimney consisting of three parts: the upper part, called the stack , the central portion called the "bosh"and a cylindrical chamber at the bottom called the crucible.
A charcoal fire was built inside and when it had reached the right temperature iron ore and limestone were added to the top of the stack.
To aid in the combustion of the charcoal, hot air was forced into the furnace under pressure. This hot air was fed into the furnace through nozzles called "tuyeres". This "hot blast" made the furnace more efficient. Hot carbon monoxide produced by the charcoal fire reduced the iron ore to pure iron which would drip to the bottom of the furnace and collect in the crucible.
When the crucible was full, the ironworkers would "tap" the furnace letting the liquid metal flow into sand molds where it would harden. Molten waste, a glasslike material called "slag" was also produced in the furnace.
Production was continuous: after tapping the furnace the fire was built up and another charge of ore and limestone prepared. Production could only be interrupted by severe drought which removed the power source for the air blast or a breakdown in the furnace. Furnaces of this type were used for the production of iron throughout the United States.
