. His partners and co-founders of the Washington chemical company, named after his home, were his brother-in-law Robert Benson Bowman and his father-in-law
Hugh Lee Pattinson. Pattinson was the inventor responsible for the process separating silver from lead that bears his name.
Charles Vane, 3rd Marquess of Londonderry, Pattinson and Bell declared themselves "chemical manufacturers and co-partners in trade". Establishing a partnership with
Robert Stirling Newall in 1850, Bell set up the first factory in the world with machines able to manufacture steel rope and submarine cable. Two years later his brothers Thomas Bell and John Bell joined him to build a major iron works at
Port Clarence,
Middlesbrough on the north bank of the
River Tees. By 1853 there were three
blast furnaces, each with a capacity of just over 6000 cubic feet, making them the largest in Britain at the time. including the
North Eastern Railway company, of which Bell was a
director from 1864 onwards, The Bell brothers' company operated its own
ironstone mines at
Normanby and
Cleveland, and its own limestone quarries in
Weardale, he described how critical it was to make aluminium pure in
The Technologist: In 1863, Bell exhibited "several pounds" of the recently discovered element
thallium when the
British Association met in Newcastle that autumn. The metal was obtained from the flue deposits (mainly lead sulphate) from the manufacture of
sulphuric acid from
pyrites, one of the products of the Washington works. All the credit was given to researcher
Henri Brivet, who was "chief" of the laboratories at Washington, having experienced "languor and headache" then known to be caused by breathing thallium fumes. The
Cleveland ironstone had been considered inferior for steelmaking, as it contained a relatively high percentage of
phosphorus at 1.8 to 2.0%, weakening the resulting iron. Bell directed large-scale experiments at a cost of up to £50,000, resulting in a
basic steel process which produced steel rails containing no more than 0.07% phosphorus. His obituary in
The Times of 1904 noted, as a sign of the progress that Bell himself had brought about, that Bell could recall "seeing wooden rails in use on the tramroads by which coal was brought down to the
River Tees". In 1882, Bell successfully drilled for salt at Port Clarence, finding an exploitable salt bed at a depth of 1200 feet. He used the salt for making
soda, but the borehole was sold to the Salt Union in 1888. He continued to own shares in
Bell companies and the North Eastern Railway. In 1901, at age 85, after a long period of difficulty for heavy industry and with fears of worse to come as manufacturing grew in Germany, America and Japan, he made a decisive move to guard the family's wealth. He sold his railway interests to the North Eastern Railway company, and the sale of a majority holding in his manufacturing companies to rival
Dorman Long was completed in 1903. From the fortune thus released, he gave £5,000 to each of his many nephews, nieces and grandchildren. ==Politics==
