Samuel Garbett and Co
1749 Two Englishmen, John Roebuck and Samuel Garbett, approached William Cadell, Senior to set up sulphuric acid works at Prestonpans.
1759 Samuel Garbett and John Roebuck built a factory at Prestonpans, in Scotland, for the production of sulphuric acid; for some years they enjoyed a monopoly. Eventually their methods became known, and, having omitted to take out patents, they were unable to prevent others making use of them.
1765 Advertisement for Samuel Garbett and Co for the Carron Wharf 'cheap carriage of merchandise from Glasgow....with commodious warehouses'. Lessees of Carron Harbour and Salt Pow. Sailings to Leith, Dundee, Perth, Arbroath, Montrose, Banff, Inverness and Newcastle. [1]
1766 The Prestopans Oil of Vitriol Works were until this year in joint ownership of Roebuck and Garbett but became Samuel Garbett and Co from this date. The works appear to have closed around 1787. [2]
