The grey gneiss from Italy is suitable for in- and outdoor applications. Its vivid pattern makes each slab look like a natural piece of art. Thanks to its acid recistance, the material is suitable for kitchen countertops and many other applications.
Granite is a hard rock of volcanic origin and belongs to the group of plutonic rocks, which originate of solidified magma deep in the Earth's crust. As opposed to this, basalt forms from the rapid cooling of lava exposed at or very near to the surface of the Earth. Thus it appertains to the group of extrusive rocks. Granite is mostly composed of feldspar and quartz, which give it a high range of hardness. It is very resistant to high wear, with superior abrasion resistance and compressive strength. The hard rock is available in a wide range of colors and is in most cases an excellent material for internal and external building use.
