Abstract: The present ceramic piece, wall tile, floor tile or similar article, refers to a piece (1) of the kind that is arranged contiguously in rows and columns in the form of a grid. The sides of the piece (1) present certain projections (2) and depressions (3) which can be slotted together, adapted to the corresponding decorative motif, which break the continuity in the lines of said grid, making it difficult to distinguish said lines and enabling the possibility of ornamentations in sets of pieces with a non-grid structure.
