With colours ranging from charcoal grey to dark black, the Brazilian Black Slate is calibrated for a practical finish, with some light layering evident on the surface, leaving no doubt this is a natural stone. The tiles have a neat square edge, which lends them to a more contemporary setting, and are commonly used in kitchens, utilities and bathrooms. The slate can be laid with a dark grout, for a more continuous, consistent look, or with a contrasting light grout to make more of a feature of the floor.
