Mendiger Basalt Lava

Mendiger basalt is a stone from Germany. Basalt Lava is a very porous stone with an irregular fracture surface that feels rough and sharp. Because the stone in processed condition remains very stiff, it is widely used especially for floors and stairs, especially since the surface even in wet state retains its skid resistance. Basalt Lava weathers negligible: the stone frost resistant and resistant to acids. At most there will be algae or moss in wet situations and will take place the stone over the centuries darker, gray to black. The material has been used for centuries for the manufacture of millstones.
