MARBLE BIANCO CARRARA
LET’S FIND OUT SOME CHARACTERISTICS OF ONE OF THE MOST KNOWN ITALIAN MARBLE USED AROUND THE WORLD:
Bianco Carrara, as the other whites of the Carrara area, is extracted from the Apuan Alpes, a complex geological structure that has formed throughout the years; at the origins, in the lower jurassic era, there were some crystal rocks that have undergone on a strong variation, transforming from a limestone structure to a chrystal one.
There are different varieties of white marble in the Carrara area, among the most popular there are Bianco Carrara, Statuario and Calacatta, which are all differently classified for the difference in the whiteness of the background, and the movement of the veins.
The Marble Bianco Carrara is one of the most known marbles of Italy around the world, it s a marble composed of a white background with a uniform and omogeneous tonality and has got grey veins, it is fine grained and there may be pyrite chrystals.
The quality of the material it’s defined by its whiteness and the composition of the grey veins.
At the quarry, the lots are classified as “C” or “CD”, whilst the “C” quality has got a whiter background, the “CD” tends slightly to a grey-ish background. So, we can say that, the whiter is the background, the greater is the quality of the material.
The Bianco Carrara marble can be used in both interior and exterior environments it is particularly indicated for floorings; this kind of material is mostly used from sculptors for artwork. The possible realizations are: floors, stairs, tables, sinks, kitchen tops, shower trays, decors and general coatings,
