The process includes the following stages: arranging a slab or tile exhibiting an in-view surface； arranging at least a slim support slab or support plate having a characteristic of possessing a thermal expansion coefficient which is greater than a thermal expansion coefficient of the slab or tile, the slim support slab or support plate exhibiting effective properties of tenacity and resistance to easy breakage thereof； gluing under heating the slab or tile onto the slim support slab or support plate, or vice versa, using a suitable glue for adhering to surfaces thereof to be glued； leaving an assembly thus obtained to cool down to an ambient temperature such that owing to a different thermal expansion coefficient (contraction), the slim support slab or support plate induces on the slab or tile, to which it is solidly glued, a state of compression starting from a lower surface thereof which is opposite the in-view surface.
