The intention of Factory is to offer a concrete effect, in full body porcelain tiles, in which the shade variation of the surfaces is very slight on each individual piece, but can takes on a greater value once the floor is finished. All of this to show that a tile is a semi-finished product, that is only really finished when it has been laid in place with other tiles.
The particular structure of the background is inspired by the formwork used by masons to pour concrete.
