Abstract
The invention relates to a coated system which has a chemically and mechanically very stable surface coating of high aesthetic attraction which has a specular and optionally iridescent color and/or a body color on a metal, ceramic or quartz glass substrate provided with an enamel or glaze coating, the surface coating being obtainable by single or repeated application of aqueous metal oxide sols, by subsequently drying and optionally igniting the metal oxide sol coating at each application step, the metal oxide sols having a mean particle size of between 5 and 200 nm, ignition being carried out at least once after completion of the final application step and at temperatures higher than 700.degree. C. and below the softening point of the substrate, the metal oxide coating on the glaze or enamel coating having, after ignition, a refractive index at least 0.5 higher than the refractive index of the enamel or glaze coating, and the total thickness of the ignited metal oxide coatings being less than 500 nm.
