Slate anthracite (Black Slate) SONAT 521 black, anthracite, natural

Because of colour, structure and the possibility of achieving relatively big pieces, slate is being used in private residential areas as well as in larger installation projects (offices, schools, etc.). It is most widely used inside as flooring material but it also can be used as a wall element. Further applications would be counter tops, steps, window sills and wash tables.
