Compositions and methods for laser marking substrates such as metal, glass and ceramic are disclosed. A marking material is applied to the surface of the substrate, followed by irradiation of a portion of the marking material to form a bright, oxidation resistant marking on the substrate. The non-irradiated portion of the marking material is then removed from the substrate. The marking material comprises compounds such as metal salts and metal oxides which, upon irradiation, form oxidation resistant metallic markings. The marking method is highly versatile, can be performed quickly, and produces permanent marks of high resolution and contrast without damage to the substrate. <IMAGE> <IMAGE>
