Blue Stone is a sedimentary rock of gray-blue color with main deposits in Belgium, France and Ireland.
It is a hard limestone, solid, heavy and compact as marble. It has the characteristics of resistance to weathering, dirt and pollution, it is non-porous, naturally waterproof, resists moisture and dries quickly.
It changes color to black / light gray / blue-gray according to processing and finishing.
The blue stone is mostly a building material but also can be used as ornamental stone.
Today it is well-known for its applications in the field of architecture and interior-design, for decorations, flooring, wall covering, thresholds, window sills, and work surfaces. It is suitable for areas that require a non-slip flooring as coping on swimming pools and edging in bathrooms.
It is extracted from the quarry in blocks and is usually only occasionally processed with splitting, almost always along the direction of the vein. Usually you obtain thin veneers from the sawn blocks. Some blocks can be split with automatic H-frame machines, such as Px series, or if the stone is particularly tall, even on P4 machines equipped with side blades.
