Although the iron manufacture had gradually been increasing since the middle of the century, it was as yet comparatively insignificant in amount. Thus we find, from a statement by W. Wilkinson, dated Dec. 25, 1791, contained in the memorandum-book of Wm. Reynolds of Coalbrookdale, that the produce in England and Scotland was then estimated to be Coke Furnaces. Charcoal Furnaces.
We are informed that it was while Richard Reynolds had charge of the Coalbrookdale works that a further important improvement was effected in the manufacture of iron by pit-coal. Up to this time the conversion of crude or cast iron into malleable or bar iron had been effected entirely by means of charcoal.
The castings of Coalbrookdale gradually acquired a reputation, and the trade of Abraham Darby continued to increase until the date of his death, which occurred at Madeley Court in 1717. His sons were too young at the time to carry on the business which he had so successfully started, and several portions of the works were sold at a serious sacrifice.
Once in every year he assembled a large party to spend a day with him on the Wrekin, and amongst those invited were the principal clerks in the company's employment, together with their families. At Madeley, near Coalbrookdale, where he bought a property, he laid out, for the express use of the workmen, extensive walks through the woods on Lincoln Hill, commanding beautiful views.
Of the products of Chelsea and Bow, of Coalbrookdale and Derby, and of Bristol and Nantgrw, writers and collectors of rare ceramics have had much to record of the many-shaped vases with which the homes of the middle classes were made beautiful in the eighteenth and early nineteenth centuries.
But when the sons had grown up to manhood, they too entered upon the business of iron-founding; and Abraham Darby's son and grandson, both of the same name, largely extended the operations of the firm, until Coalbrookdale, or, as it was popularly called, "Bedlam," became the principal seat of one of the most important branches of the iron trade.
Ford succeeded at Coalbrookdale in smelting iron ore with pit-coal, after which it was refined in the usual way by means of coke and charcoal. In 1762, Dr.
Ford, of Coalbrookdale in Shropshire, from iron-ore and coal, both got in the same dale, makes iron brittle or tough as he pleases, there being cannon thus cast so soft as to bear turning like wrought-iron."
It occurred to him that these inconveniences would be obviated by the use of rails of cast-iron; and, having tried an experiment with them, it answered so well, that in 1767 the whole of the wooden rails were taken up and replaced by rails of iron. Thus was the era of iron railroads fairly initiated at Coalbrookdale, and the example of Mr.
Watt had not yet perfected his steam-engine; but there was a considerable demand for pumping-engines of Newcomen's construction, many of which were made at the Coalbrookdale Works.
