"Marble is the synthesis of a metamorphic process that limestone or dolomite rocks undergo, which transforms the calcium carbonate, of which they are mainly made, into calcite or dolomite crystals. A modification process given by high pressure and temperatures, the rocks are subjected to, a process that almost completely eliminates the fossils they contain.
The modification process is also able to define the colour of the marble, thanks to the crystallization of impurities contained in it, such as iron oxides, sand, silt, clay. The white colour of some marbles is directly influenced by the absence of impurities inside. "
