This stone was pushed up to the surface millions of years ago under high pressure. The clay eventually developed into slate. The type of clay determines the shape and look of the slate, so there are quite a number of types available. You can clearly see the different layers of this natural stone.
Slate is most beautiful in a natural, coarse finish, but it can also be honed.
- Honed: a faint reflection on the smooth, matte surface. No visible cuts.
Slate is primarily popular as roof covering. This natural stone lets through little water, is frost-resistant and is very hard. Because this stone can also be honed, it can be used as floor covering or wall cladding.
