The flues for the furnaces inside the structure would have ran underneath the cone whose height was designed to produced a draught of air through the furnace which increased the heat generated. Coal, mined locally, was used as the fuel.
The cone was restored in 1993, with a door inserted on the north-west side, and has been used as a factory and showroom.
This imposing structure is said to be one of the most important industrial monuments in the North East.
