Description: | Sgurr Coire nan Gobhar, Loch Nevis, Knoydart. Inverness-shire. Opencast mica workings. Samples of mica books after rough dressing (rough cobbed) as sent for processing at the Pitlochry Depot. (Note 0.15 m. scale at base.) After mining the purpose of the Rough Dressing Station on the lochside at Knoydart was to reduce the mica books in thickness by splitting and then cut out the more obvious defects. The Knoydart production was brought down the hillside by pony, carried by launch to Mallaig and then by rail to Rannoch. At Rannoch it was sent by bus to Pitlochry. Sheet mica for industrial use was processed into one of two types: 'sheets' from one inch square upwards and from a few thousandths of an inch to one-eighth of an inch thick flat and free of flaws, or 'splittings' these were usually less than one inch square and one thousandth of an inch thick. Splittings were cemented together with shellac to form mica boards. |
