Caption: Specimen of Copp Cragg sandstone, Copp Cragg Quarry, Redesdale Camp, Byrness, Northumberland.
Description: Sample of Copp Cragg sandstone from the building stone collection of the Edinburgh World Heritage Trust. The stone has a cut surface with an orange-brown colour. This sample forms part of a collection of sandstones which are used by the Edinburgh World Heritage Trust to aid the selection of replacement masonry which matches the appearance of original stone. Edinburgh World Heritage Trust sample no. EWHT 95. Selection of matching stone for masonry repair should not rely solely on appearance, since stones of a similar colour but from different geological strata may weather differently. What may be a good match initially may not be so after a few years. This specimen is of Carboniferous age. Stone extracted from the same quarry and bed may vary considerably, and at any time a quarry may be extracting stone from several beds each with its own characteristics.
