This was principally around the Firth of Forth but also as far west as Arran and as far north as Brora in Sutherland. Water was pumped from the sea into huge iron pans. Coal was burnt in furnaces beneath them until all of the water had been driven off. The less than pure salt was then drawn off, stored and bagged. Prestonpans was one of the first and the last salt-panning site in Scotland. The building with steam seeping through its roof housed a working salt pan, as did others to its left. This photograph dates from the early 1950s. Resource pack   1     2     3     4
