In the early eighteenth century, Blackhall Mill changed from a mainly rural estate to a steel making village.

The Bertram family operated a steel forge from the early 1700s. It was visited in 1719 and 1754 by Swedish engineers. Both Kalmeter in 1719 and Angerstein in 1754 visited the papermill which was operated by the same millrace as the forge. Angerstein, on his visit in 1754 was studying new methods of industrial technology. At that time, conversion of iron into steel took eighteen days, with most of the time taken by cooling. Profit was sixteen per cent. There is reference to a smelt mill at Blackhall Mill in an indenture of 1773, and Mr. William Bertram of Ryton parish was owner or part owner of the sword factory at Blackhall Mill at the same period. The Blackhall Mill steel forge (later the site of the council school) used power from a dam across the Derwent near Beechgrove Terrace.

Angersteins journey can be traced at which indicates almost every forge and mill in the line of travel and a map can be seen... He indeed visited Shotley Bridge.
