THEMABeschreibung
TEXThese are almost the oldest iron works in Scotland, and are famous in connection with the researches and discoveries of David Mushet and James Beaumont Neilson (Proceedings 1859, pages 98-108; 1860, pages 65-8). David Mushet joined the staff as accountant in 1791; and during the time he remained in that position he made a large number of experiments in assaying, roasting, and cementing iron ores, de-carbonising cast-iron for the production of steel and bar iron, and various other operations. He was the discoverer of the following processes: the preparation of steel from bar iron by a direct method, combining the iron with carbon; the beneficial effects of oxide of manganese on iron and steel; and the application of the hot-blast to anthracite coal in iron smelting. In 1799 he discovered titanium, upon which his son has founded the titanium process.

When J. B. Neilson first proposed the hot-blast in 1825, the idea was ridiculed by almost all the ironmasters in Scotland, none of whom could be induced to try it on their furnaces, until at length he persuaded Mr. Charles McIntosh of Crossbasket and Mr. Colin Dunlop of these works to allow a trial of his process to be made on one of their furnaces. After experimenting here for some years, the idea was matured into a definite and practical form, and its value for iron-making was at once admitted.

At present there are four blast-furnaces in operation here; the brands of pig-iron made are "Clyde," "Monkland," and "Clyde Hematite." The furnaces receive blast from a blowing engine, with two steam- cylinders 50 inches diameter, and two air-cylinders 100 inches diameter by 9 feet stroke, connected by massive walking beams. There is also an auxiliary blast-engine of smaller dimensions, kept in reserve. Instead of the waste gases from the blast-furnaces being used at once as gaseous fuel, they are passed through ammonia apparatus, in which sulphate of ammonia, oils, tar, and pitch are produced. The gases are drawn through by four Root's exhausters; and after being washed, cooled, and deprived of their tar and ammoniacal products, are then passed on for utilization as fuel. A portion of the gas is used for raising steam in the boilers supplying the engine in connection with the hoists, blowers, and exhausters; while another portion is used in regenerative hot-blast stoves. The workshops comprise joiners', engineers', and blacksmiths' shops, and a foundry in which castings are produced both for use in the works and also for outside supply.
