1. A method for coating a glass or glass ceramic substrate, comprising the steps of:
preparing a suspension comprising a glass powder and an agent that decomposes upon temperature increase to form a volatile substance;
applying the suspension to the glass or glass ceramic substrate so that at least part of the substrate is covered by the suspension;
fixing the suspension applied on the substrate at a first temperature between 0° C. and 300° C. to form a substrate with a fixed suspension;
annealing the substrate with the fixed suspension at a second temperature between 450° C. and 900° C. so that the glass particles melt and the agent decomposes to form the volatile substance and to cause formation of a coated substrate with an enamel coating that has closed pores; and
cooling the coated substrate to room temperature.
