Slate found at Glendyne’s quarry is dark grey with a tone of blue. Its colour is very homogeneous despite the presence of a light stratification marked by silty beds which, often of very fine nature, do not affect slate schistosity.
Due to the Nordic climate, surface alteration is very low. The deposit was preserved from meteorological alterations typical of temperate and hot climates. The Glendyne quarry is thus proud to produce stones of very high quality. glendyne slate is pre-sorted for easy installation
