1840 The Derwent Iron Company was promoted by Mr. Jonathan Richardson and a small group of entrepreneurs to lease ironstone in the district of Consett, as well as several large royalties of coal. Blast-furnaces were erected, and rolling mills laid down, the ironstone for the former being obtained from shafts sunk in the immediate neighbourhood.
Over the next 100 years, the town became one of the world's leading steel making towns. Steel dominated Consett visually in terms of its landscape, the town becoming renowned for the pall of red dust that hung over it. The dust was actually airborne iron oxide from the steel making plant.
1857 The Derwent and Consett Iron Company was formed to acquire the assets of the previous company which had large debts to a bank which had failed.
The Derwent and Consett Iron Company could not proceed so the business was again put up for sale.
1861 Consett Iron Company gained orders from the Admiralty for plate and iron
1864 The New Consett Iron Company Ltd was incorporated in order to acquire the works at Consett, Crookhall, and Bradley, consisting of 18 blast-furnaces, with puddling forges, extensive plate, angle and bar mills, and other adjuncts, producing 80,000 tons of pig iron per annum, and from 40,000 to 50,000 tons of finished iron. 500 acres of freehold land, attached to the Works, and more than 1000 freehold cottages, with manager's house and offices, were included in the purchase, as well as coal royalties.

Only 6 of the 18 blast-furnaces were in blast; there were 99 puddling furnaces at Consett and 31 at Bishopwearmouth Iron Works, which had been amalgamated with the Derwent Iron Company at an early stage. To the north of the main works were Tin Plate Mills, owned by Richardson and Co
1866 The tin plate mills were acquired including 27 puddling furnaces and 3 plate mills and a colliery which was much nearer the Works than their own pits. The ironworks at Bishopwearmouth were soon dismantled and the operations concentrated at Consett; the manufacture of tin plates was discontinued.
1878 The company was the largest maker of plate in the country; it employed 5000.
