The raw iron ore was prepared in (1) The Ore Kiln, before being dumped into the furnace through the (2) Top Houses.

The raw ore was superheated in the furnace by burning the wood charcoal produced in the brick kilns.
Mixing the ore with limestone caused a chemical reaction that produced the molten iron that flowed out of the bottom of the furnace and into the (4) Casting Shed.
Here, men formed molds and channels out of sand on the floor.
The liquid iron trickled through the channels and filled the molds to form the "pig iron" bars that, when cooled, were sent to market on the train.
By the 1880's, the steam locomotive could pick the bars up right outside the casting shed and carry them down to Bangor where then could then be sent by ship to anyone who purchased them.
