TRAVERTINO: it is a chemical type of sedimentary limestone rock. Normally very used in building, especially in Rome, since the first millennium b.C. It is found in a variety of natural colours from milk-white, to a walnut white, and several hues from yellow to red. It is a tough but docile stone, usable for flooring and cladding both indoors and outdoors, in some cases it is used for sculpting.
PORPHYRY: it is a variety of igneous rock often used for external works because of its high resistance to extreme weather conditions. It was used by Etruscans and Romans both in art and construction work. Trentino is one of the most famous extraction locations, and as a consequence the landscape of this region has been significantly compromised by the open air quarries.
PIETRA SERENA: it is a grey sandstone of a particular shade of gray, also used in sculpting. It is typical of Tuscan architecture especially in Florence. Its grain varies, depending on the quarry. From a fine to medium grain to a large pleasantly compact grain with shiny specks indicating the presence of mica.
It can be chiselled, polished, flamed, bush-hammered, grooved, sandblasted, etc.
LUSERNA STONE: It is a shiny laminar gneiss, an unalterable material, weather and abrasion resistant.
It comes in three different chromatic hues: golden, gray and reddish.
"A wet finish" enhances its golden hues. Great for: sidewalks, shelves, steps, bases and also employed, with great aesthetic result, for making gutter grids. The natural roughness renders this material slip proof when wet and it feels comfortable when walking on it.
MARBLE: : it is a limestone rock of medium hardness. It is usually formed of fine grain crystals. Its composition allows for exceptional results when polished. It is equally used for internal and external works. White marble is used to make ornamental objects, sculptures and above all it is used in construction and street finishes.
CARDOSO:this material has been mined since ancient times in upper Versilia (Tuscany), from which it takes its name, in the impressive mountain range of the Alpi Apuane. Dark gray tending to a deep blue, this rock derives from sandstone from the fragmentation of granite and does not have a very deep metamorphism.
It has optimal physical characteristics with a high resistance to wear, sliding and tension, as well as an ideal resistance to the wear and tear of weather conditions.
BOTTICINO: it is a cream coloured marble with lighter spots, and a very fine grain. It is characterized by some yellowish stylolitic surfaces and some rare thin whitish veins. Resistant to very low temperatures, it is hard and not brittle. It is the ideal for external use.
BARDIGLIO: a precious grey coloured marble, with dark gray and white cloud-like patterns on a darker bluish background. There are two different types: the imperial and the classic. This marble is extracted from the quarries of Carrara. It is finished and usually used for flooring and cladding. Outdoors it is greatly employed to floor public squares and sidewalks, while indoors it is the ideal in bathrooms, kitchens and for windowsills. The surface can be finished in several ways: polished, burnished, sanded and antiqued.
SANTAFIORA: the natural Santafiora stone takes its name after the torrent that flows at the feet of the Manciano (Grosseto) quarry. From a sandy yellow (Havana yellow) to a light brown, it contains hardly perceivable stratifications, which confer evocative polychrome warm toned effects.
Its hardness makes it especially used in claddings, ventilated walls, and for extensive outdoor floorings exposed to ice, salinity and in seismic zones.
