Natural StoneNatural stones are the first materials used for construction. Not only the charm that they have already existed for millions of years, but also because of their properties such as the resistance, compactness and durability make them superior to any product.
Natural stones are flame-retardant, hygienic, non-toxic and biocompatible. They are an authentic product of the earth, perhaps that is what gives them their eternal charm. In the Green Building they are used naturally; the process of extraction and processing has a minimal impact on the environment compared to the materials of industrial production.
In the international standard of Neapolitan pizza, it is written very clearly: "The true Neapolitan pizza is spread only by skilled hand movements on a flour-covered marble slab."
The pesto from Genoa is traditionally made by pounding with a wooden mortar in a white marble bowl. In the kitchen, stone pots are used to cook certain foods or soapstone as a cooking plate. In antique as well as in modern olive mills olives are poured into a pan mill, in which the granite wheels, called "butcher", run on the ground, and extract the oil by squeezing.
The word marble is often used as a synonym for natural stones, in the Greek etymology it’s called marmairon ', with the meaning of polished stone. Modern geology, however, uses the word marble to indicate only one particular class of polished stones, the white metaphoric marble, thus left room for other categories of natural stones such as granite.
In the European market, natural stones used for construction must comply with the Construction Products Regulation since 1 July 2013 (CPR 305/2011).
