North Yorkshire Ironworks
of South Stockton
As an experiment in making steel from Cleveland ore, Bernhard Samuelson sent a quantity of iron, made at his Newport Ironworks, to France to be made into steel using the Siemens-Martin process. The results of these experiments appeared to be successful so, in 1869, he leased the North Yorkshire Ironworks at South Stockton for large scale manufacture of steel. With great expenditure of labour and capital, he adapted them for the manufacture of steel on the Siemens-Martin system. However practical difficulties were such that the promise of the early experiments was not fulfilled. His failure cost him between £25,000 and £30,000
