A method of introducing weakening into a solid or a workpiece, preferably a ceramic or a glass, by an energy source which, by means of specific energy input acting locally, weakens the solid or the workpiece at the location of the energy input. A chromophore substance is applied to the location of the energy input before or at the same time as the energy input, such that a physical, chemical or biological visible change in the solid body or the workpiece is achieved at the location of the energy input. |
