In the building industry, one of the most used precious stones is marble. More and more customers are oriented towards this stone for the covering of several types of surfaces, from flooring to walls and to the increasingly requested decorations as well as the creation of original furnishing accessories able to combine functionality and design.
It is not only the aesthetic value of marble that makes this material preferable over many others available on the market. Marble is in fact one of the most resistant natural materials both to abrasions and to impacts. Not to mention the comfort in cleaning and a series of features that guarantee a durability and brightness without comparison.
The veins of the marble, the delicacy of the colours and its particular brightness make this stone one of the preferred materials for covering any type of surface. In particular, marble is widely used in sophisticated and elegant premises, or in representative spaces for both the public and private fields. Marble stairs, marble fireplaces, classic marble bathrooms are increasingly popular items.
The style is also joined by comfort, as in the case of the marble kitchen floor as well as marble sinks, beautiful to look at and easy to keep clean. There is no limit to the imagination and to the demands of the market: recently, objects of desire, luxury and comfort have been materializes into real material products such as marble pool tables or marble saunas directly in the bathroom of the house.
Marble is a crystalline and pure metamorphic rock composed almost exclusively of calcium carbonate.
The formation of marble takes place through what is called a metamorphic process of crystallization: calcium carbonate, when it comes into contact with sedimentary rocks, gives rise to a set of calcite crystals and various minerals (such as silt, sand, clay, iron oxides and flint nodules). These (together with other factors such as temperature and pressure) determine its specific coloration.
On the market there are different varieties of marble, depending on its intrinsic characteristics. There are crystalline limestone marbles, which are generally the oldest stones and are found in both white and coloured. Alabaster and travertine are part of the crystalline limestones.
But there are many others, all similar but each one with its own specific feature: limestone marbles, clastic marbles, serpentinous marbles (generally green) and many others (such as Carrara marble which is a specific type).
Marble is then classified into different types depending on the colour, appearance, origin. However, regardless of its classification, the rock certainly guarantees aesthetic and mechanical characteristics without equal. The hardness and the resistance of marble make it one of the most precious stones and therefore used in large scale. It has always been a symbol of elegance and style.
The characteristics of the various types of marble depend on the nature of the area which hosts the quarry. There are lots of differences if the quarry is in the mountains or in the plains. In recent times, the discovery of new materials capable of accurately cutting even the hardest stones has led to the creation of ever more innovative cutting techniques.
From the ancient iron we have moved to the use of the helical wire, consisting of a cutting material such as quartz sand, for then moving to the diamond wire or chain saws, which are now the favorite techniques for cutting marble. Today you can make any object you want in marble: just imagine.
Marble can undergo different treatments once it is extracted. Among these, the most common are polishing and sanding (made with chemicals or special machinery), flaming (the most common processing done on marble for outdoor uses), rifling, sandblasting (sanding through water jet and sand) and brushing.
