Beautiful Slate is a foliated rock that gets its name from its layered structure and is composed of clay or volcanic ash. Slate is used as a building material, because it doesn't burn, doesn't absorb moisture, and is durable. It is most often used for making tiles, parts of the interior and exterior of roofs, buildings, floors, facades. Slate often has an amazing gray color, especially when used for building roofs.
