Abstract: A modular mosaic architectural component having at least two mosaic pieces, and at least one support surface covered with the at least two mosaic pieces. The at least one support surface is preferably recessed with respect to a rim of the surface such that external surfaces of the at least two mosaic pieces are essentially at a same level of the external surface of the rim.

Abstract: A wall and/or floor tile (10) comprises a container element (1) and a filling material (2) disposed inside the container element and constituted by a polymeric material having a Shore hardness of between 55 and 85, preferably 75, and a setting time, at ambient temperature, of between 5 and 15 minutes, preferably 10 minutes. The filling material (2) is produced from a multi-component material, preferably a two-component material. An apparatus (20) for the production of a wall and/or floor tile (10) comprises at least one supply head (22) provided with injector means (24) having separate supply circuits (26, 28) for each of the multiple components. The filling material (2) is supplied into the container element (1) in controlled manner by a single nozzle (30) for mixing the multiple components, in order to form the wall and/or floor tile (10).

Abstract: A mosaic tessera, particularly for outdoor and/or indoor paving, constituted by a small metallic plate which is peripherally provided with perimetric raised portions forming a recess together with the corresponding face of the plate and by a filler element which is shaped complementarily to the recess and is associated with the recess so as to form a single tessera adapted to be applied to the foundation of the paving.
