<p>A method for locally satin finishing a piece made of hard material, particularly of ceramics, thereby allowing a pattern to be formed on the surface is provided. In a method of making a satin finish surface on a piece made of a material including at least one polished surface and having a Vickers hardness greater than 1000 HV, the method comprises the steps of: providing a pulse laser, which can make a relative movement with respect to each other in an XY plane, and a support for the piece; locally exposing the polished surface to laser pulses with enough energy to cause local melting of the polished surface by forming a micro-crater(10); repeating the laser pulses simultaneously according to a relative movement of the piece with respect to the laser so as to trace micro-creases(12) on the polished surface formed by aligning several successive partially overlapping micro-creases, wherein the micro-creases together define the satin finish surface, are parallel to one another, and are formed in an equal distance.</p> |
