| Caption: | Specimen of roofing slate from Sandilands Farm, 6 miles south of Lanark, Lanarkshire, Scotland |
| Description: | The sample is a broken piece of a slate from an old farm building. It is a fine-grained and uniform slate with a relatively smooth cleavage surface and a distinctive purple colour. British Geological Survey Petrology Collection sample number EMC 5818. Although not known for certain, it is likely that this is a specimen of Welsh slate. Welsh slate is commonly purple in colour and has a similar high quality cleavage. Purple slate is only found in a few localities in Scotland such as parts of the Aberfoyle quarries. However it is not common and is only rarely seen on roofs. Welsh slate became more common in Scotland following the introduction of the railways in the middle of the 19th century. Many roofs in the Borders in particular were constructed or re-roofed using Welsh roofing slate after this time. |
