Claim:
1. A coated glass or glass ceramic substrate, comprising: a substrate; a layer covering an area of said substrate, the layer being comprised of a layer-forming material including at least partially melted glass flow particles and texturing particles, the texturing particles having a melting point above a burning-in temperature of the layer-forming material so that the texturing particles are embedded in the layer in a manner that retains an initial outer contour of the texturing particles with the texturing particles partially protruding from the layer, the layer-forming material comprising in wt. % Al wherein the texturing particles are polysiloxane-based particles, wherein the layer has an average layer thickness at locations without the texturing particles that ranges from about 0.1 μm to about 20 μm, wherein the texturing particles produce a haptically perceptible texture that has a surface roughness value from 0.2 μm to 1.2 μm, and wherein the initial outer contour of the texturing particles comprise substantially edgeless and/or rounded outer contours to cause a velvety perception of the layer.
