Basalt is a volcanic rock, usually black in colour, finely- grained, very hard and with a high content if iron and magnesium. The PROGRAMA OPAC consist of slabs formed entirely by dry basalt matter, which increase resistance to breakapage. It is similar to igneous rock not only due to its appearancem but also because it has the same composition. The rock which is initially crushed and sieved to achieve the best granulometry, is subsequently reconstituted to form a basalt slab.
