Scottish iron When Henry Cort visits Scotland in 1784, there is only a handful of ironworks there. The earliest has been set up by an English initiative in 1759. Two Birmingham entrepreneurs, John Roebuck and Samuel Garbett, join with local man William Cadell to build the Carron works, on a fast-running tributary of the Forth near Falkirk. Roebuck also purchases a mill on another tributary at Cramond near Edinburgh. For a while the enterprises are run jointly. Iron is smelted and fined at Carron. Smelting is done with coke, fining largely with charcoal (although Roebuck does patent a process using coal). Much of the fined iron goes to Cramond to be turned into nails and hoops. Both Roebuck and Garbett run into financial problems with other ventures, and control of Carron passes to Garbett's son-in-law Charles Gascoigne. These developments have often been depicted as deliberate machinations by Gascoigne, but some of his correspondence with Boulton & Watt suggests otherwise.
Gascoigne experiments with new methods of fining, but is unable to come up with anything worthwhile. His most significant contribution is the carronade, a small cannon that can fire a large ball. A succession of naval victories later ensues. Meanwhile the Cadells have taken control at Cramond, which becomes a separate works, importing much of its raw material from Sweden. In 1774 they make a determined effort to expand their customer base. The Gosport business is one of their targets. They threaten to sell nails directly to the Navy in competition. Attwick and Morgan, who have been getting their ironmongery from the West Midlands, succumb to this threat. When he takes over their business, Cort finds Cramond is the main supplier of nails. He is not happy with the supply he gets.
Cramond retorts that he has failed to specify his needs properly. Apparently the dispute is never solved, despite repeated attempts at agreement.
Edington is present at some of Cort's demonstrations in 1784. Maybe his influence is one reason that Cort's process fails to gain a foothold in Scotland at the time, despite a promising initial response. Meanwhile in 1779 three Scottish brothers, the Wilsons, have embarked on a new venture, establishing an ironworks they call Wilsontown in Lanarkshire. For a while they employ John Mackenzie as manager. He has left by the time of Cort's visit. Two years later he and Edington set up the Clyde ironworks. From this point iron production in Scotland starts to take off. It receives a great fillip when David Mushet (originally a Clyde employee) discovers the black band ironstone, an ore containing enough carbon to obviate the need for coke in smelting. Mushet's son will become instrumental in the attempts to rehabilitate Cort's name in the 1850s.
