Method for producing mosaic tesserae and tesserae obtainable by using those tesserae

摘要

A method for producing mosaic tesserae from a plate-like matrix having a laying surface and an opposed visible surface is described. The method comprises the step of cutting, with first cutting means and starting from the laying surface of the matrix, at least one first groove having a depth less than the thickness of the matrix so as to define at least two portions of the matrix and a wall joining the at least two portions. A step is then performed in which a second groove is cut in the wall by means of second cutting means, the second groove being of a depth such as to separate the at least two portions of the matrix and of a width less than the width of the first groove.
