The invention relates to a method for colouring pieces of rock, namely marble, by means of the application of a laser beam (2) in order to colour-mark or totally colour the piece of rock. According to the invention, the laser beam interacts with the piece of rock (5), to which an appropriate colouring is subsequently applied. Diffusion of the pigment in the piece of rock changes its colour in the area affected by the laser. The piece or rock takes on the colour as intensely as desired. The invention enables marble of a lower value to be made more valuable and increases the value of other rocks and allows them to be coloured. This application is mainly intended for the treatment of ornamental rocks.
Procédé de mise en couleur de morceaux de roche, à savoir de marbre, par application d'un faisceau laser (2) permettant de conférer une couleur à tout ou partie du morceau de roche. Le faisceau laser coopère avec le morceau de roche (5) auquel on applique ensuite un colorant approprié. La diffusion du pigment dans le morceau de roche en modifie la couleur dans la zone touchée par le laser. Le morceau de roche revêt une couleur ayant l'intensité voulue. Par conséquent, on peut valoriser du marbre de valeur inférieure, et valoriser et colorer d'autres roches. Ce procédé est destiné principalement au traitement des roches décoratives.
