A method of laser marking metals, plastics, ceramic materials, glazes, glass ceramics, and glasses of any desired form, which comprises applying to the material to be marked a variable thickness layer of marking material containing energy absorbing enhancers then irradiating said layer with a laser or diode based energy source such that the radiation is directed onto said layer in accordance with the form of the marking to be applied, and using a laser or diode based energy source of a wavelength which is sufficiently absorbed by the marking material so as to create a bonding of the marking material to the surface of the workpiece at the irradiated areas.

[ I claim:] [1.] A thermally activated, chemically based marking method comprising the steps of:applying a layer of glass frit material containing an energy absorbing enhancer to a glass substrate;irradiating said layer with a radiant energy beam having a wavelength selected to excite the energy absorbing enhancer in accordance with the form of a marking to be applied, thereby forming a bonded and permanent marking layer atop the substrate which is visible in contrast with the substrate; andwherein the layer of glass frit material further comprises a thickness ranging between 5 and 500 microns.
