The main extraction poles of Luserna stone are located in the municipalities of Luserna San Giovanni, Rorà and Bagnolo Piemonte and extend over an area of about 50 square kilometers. Morina Pietre quarries are located in the municipalities of Rorà and Bagnolo Piemonte. From these sites Luserna stone is extracted in all its chromatic variations: Mixed Grey, Grey first choice, Blue and Yellow.
Shiny material, unalterable to bad weather and resistant to rubbing. Thanks to its geophysical characteristics, Luserna stone is frost-proof and has an incomparable resistance even if of reduced thickness.
La Luserna Stone is the product of the metamorphic and structural transformations, which occurred between 130 and 65 million years ago, of an alpine rock of magmatic origin.
Today the Luserna Stone, whose market has expanded worldwide, is appreciated both for its very high aesthetic quality and for its physical characteristics.
It is used in public and civil construction for the construction of floors, walls,, arredi exterior and interior furnishings with various top finishes: natural, flamed, brushed, polished, honed and shot-blasted.
Luserna stone colours
GREY FIRST CHOICE
The Luserna stone, an ancient and durable material, is used in construction and interior and exterior furnishings.
This metamorphic rock, made up of layers that resemble the pages of a book, is mainly extracted from quarries between the Pellice Valley and the Po Valley, in the province of Turin and Cuneo.
Luserna stone characteristics
Luserna stone is a lamellar stone, belonging to the group of gneiss. The rock is mainly composed of white mica, feldspar, quartz and green mica.
The largest percentage is made up of feldspar, which gives the stone a pale grey colour, and in smaller percentages of quartz, of yellow colour, and of mica, visible in the stone with shades of white and green. The variable percentages of the components of the rock give it the peculiarity of having different types of predominant colour, diversified by the presence of yellow quartz and greenish mica.
Luserna stone colors
The Luserna stone, thanks to its variable composition of different materials, can be chosen in four different colours.
- Mixed grey, characterized by a slightly darker grey that is not entirely homogeneous, a mixture of all its main components.
- Grey first choice, characterized by a much softer and more compact grey, which does not show marked signs of different coloured veins.
- Blue, characterized by a greyish base but with bluish-green veins.
- Yellow, characterized by a greyish base but with prevailing veins of yellow, which give golden tones to the stone.
Luserna stone is extracted from quarries in blocks of considerable size. Slabs are obtained from these blocks, generally cut with diamond wire and expansive mortar. Those slabs are then cut to produce the components used in the furnishing of houses, buildings and courtyards.
The different stone processes
After having extracted the raw material and obtained big slabs, Luserna stone is processed according to its final use.
There are different types of top and edge finishing.
– Top finishing:
The blocks are composed of layers of different thickness. You can divide the blocks into layers and then use the resulting slabs to produce flagstones, hand cut tiles (squared slabs for floor with hand-hammered edges), cubes, pavers, strips. The blocks can also be sawn in pieces with a rectangular or square section and from these the stone is split along the grain to obtain floor tiles with sawn edges.The natural surface is the most used in external finishing. The color is bright, the look is rustic and the surface is non-slip.
Surface sawn, flamed, brushed, polished:
The blocks are sawn into big slabs. Then the slabs can be flamed, which gives a rustic appearance to the surface while maintaining the regularity of the top. The flamed surface is non-slip and suitable for outdoors. The flamed surface can finally be brushed to make it smoother to the touch and easier to clean. The brushed flamed finishing is perfect for interiors (tiles, stairs, countertops). The slabs can also be polished to create kitchen tops, stairs, window sills for interiors.
– Edge finishing:
edges are sawn with disc saws (floor tiles, cladding stones and products on demand)
Hand Hammered Edges:
Edges are split by hand with a hammer. With this method, we produce hand cut tiles and roofing tiles.
Slabs are cut with a shear that uses compression to cut the stone. With this process, we produce floor tiles, cubes, pavers, strips.
Environment and stone uses
In ancient times, stone was used as a real element of the wall construction, but also used for urban flooring, for the roofing of buildings and in funerary buildings. It was also used as a material for the construction of noble courtyards and royal palaces to bring greater stability to the construction. The fields in which this stone can be used in the modern age are therefore many. Its great resistance to cold, bad weather and time make it suitable for coverings, flooring of different styles for urban and household use, internal and external steps, windowsills, threshold and all the accessories or garden furniture. In interior furnishings, Luserna stone can be used for wall coverings, as a kitchen top, to create stairs and any furnishing accessories.
