| Description: | This sample is a typical Westmorland or Cumbrian slate with a greenish-grey colour and a rough surface, with irregular hand-cut edges. This sample is a typical Westmorland or Cumbrian slate with a greenish-grey colour and a rough surface, with irregular hand-cut edges. Edinburgh World Heritage Trust sample no. EWHT 139. Cumbrian slate can be seen on many buildings in southern Scotland. It has proved popular in recent years as a replacement for Scots slate which is no longer produced. The colour of slates generally results from the presence of iron-rich minerals; red and purple from fine-grained haematite; grey and blue from variable amounts of pyrite. Oxidation of pyrite can cause red staining. |
