International and national exhibitions become a ground for comparison with more capable and powerful factories. This allows us to understand how challenging the competition is in the artistic realm. By recognizing the qualities of local clay and realizing its innovative potential, with the publication of the Law of June 20, 1871, regarding the civic numbering of buildings and the indication of streets and squares, the 'Carlo Rubbiani' company initiates the production of ceramic plaques for the naming and numbering of streets and squares. These are innovative products, inexpensive, and virtually without competitors (except for the renowned Ginori di Doccia). They mainly come in white and blue colors and are soon adopted by over 150 Italian municipalities and beyond.
The success of producing street plaques opens up new possibilities for the company. This experience effectively marks the transition to decorated 'quadrelle' or 'tiles' for interior spaces, a product that will monopolize the entire production for the first time in Italy.
The tile meets the requirements of rationality, hygiene, durability, and cleanliness demanded by the early national regulations for commercial establishments, public structures, and workplaces.
Even residential homes undergo transformation.
The success of decorative tiles for wall covering is immense. The repertoire is constantly renewed, and the widest range of decorative techniques is employed to create individual elements and compose large decorative coverings.
