1865 Daniel Adamson and a group of Manchester businessmen built the North Lincolnshire Iron Works' furnaces on a plot of land east-south-east of the Frodingham Iron Co's works near Scunthorpe. The new company was named the North Lincolnshire Iron Co.
1872 The company was registered on 7 October. 
1914 Large quantities of potash were needed for producing high quality lenses for the Royal Navy. The source had been in Alsace, now occupied by Germany. The British Potash Co was formed by British Cyanides Co, North Lincolnshire Iron Co and others, who combined with the government to develop the potash industry in the UK.
1927 By this date, the Scunthorpe plant consisted of three furnaces, and had a total capacity of 3,400 tons per week. See Aberconway for information on the company and its history.
