Abstract

A method of manufacturing a flat, glass-like or ceramic moulding having a structured surface, in which a rotationally symmetrical, moist green body is manufactured from a suspension of a highly dispersed, powdered solid material and a dispersing agent by centrifuging in a hollow mould, whereafter said green body is removed from the hollow mould and, if necessary, rolled out subsequently, cut up and, after which it is spread out on a structure-imparting substrate, the surface is embossed by applying pressure and, subsequently, the glass-like or ceramic moulding is produced by drying and sintering.
