Photograph captioned 'Copper Slag. Slags of various kinds assume different shapes and colours as they solidify. Many thousands of tons of slag, ferrous and non-ferrous, from ironmaking blast furnaces and copper and lead smelting works have been deposited in many parts of South Wales. Here and there slag tips grew into hills and changed the shape of the landscape. The slag of the stone blast furnaces was a pretty green on occasions, the dark brown copper slag was often broken by pockets of light blue. This close up of copper slag from an old smelting works at Burry Port, Carmarthenshire, suggests the bubbling of glutinous mud of the movement of molten volcano lava - anything but common slag'. Mounted on card. Made for the exhibition RECORDING WALES 3 in 1970/1971.
