| Description: | The Loch Maree iron smelting furnaces are the oldest for which there are definite records c. 1607 to 1677. They superseded old furnaces and even older bloomeries. British Geological Survey Petrology Collection sample number MC 7357. It may be assumed that the local supplies of bog iron ore that were found in comparatively small pans in this area were used up at an early stage. Bog iron ore is recent in age and was deposited in lakes or lagoons that had restricted movement for bacteria. It can be found in a range of colours from reddish, blackish to yellowish, it is often compact with a fine grain size or, more commonly an oolitic porous texture in which the spherules are consolidated by clays and limonite. |
