The increase of the use of natural stones and marbles in the Thirties of 20th century, after two decades 46of “artificial stone”, was led by architects of the milanese school (Lancia, Muzio, Ponti, Portaluppi etc.). The use of natural stone was in agreement with the policy focused to improve the utilization of products of the Italian territory; this policy brought the opening of new quarries, but also brought the exploitation of ancient ones using up-to-date methods. The architects mainly paid attention to employ each stone for a specific purpose (cladding, floor, upright structural member, decoration etc.) according to its features (origin, mineralogy, texture, workability, resistance). The combined use of different stones in a single building was the obvious consequence of this option. In addition, the orientation of the cut of veined or brecciated blocks was accurately chosen in order to obtain slabs where the disposition of veins and colours was improved. Finally, in some cases, the stone elements were designed and manufactured to be exactly set only in one particular position of the whole building.
