“Scottish slate” usually refers to natural roofing slate quarried in Scotland—famous for its durability, distinctive colour, and long lifespan.
Here’s a quick overview:
Key Types of Scottish Slate
The most well-known varieties historically include:
-
Ballachulish Slate (Argyll) – The iconic Scottish roofing slate; dark blue-grey, extremely durable.
-
Easdale Slate (Inner Hebrides) – Fine-grained, blue-black, splits very cleanly.
-
Isle of Luing Slate – Dark grey, similar to Easdale but with subtle colour variations.
-
Aberfoyle Slate – Less common; typically darker with a slightly coarse texture.

Modern Availability
Most original Scottish quarries closed in the 20th century, so reclaimed Scottish slate is widely used today. Some limited new production exists (e.g., small-scale operations around Ballachulish/Easdale).
