  • Publication number: 20010002292
    Abstract: A thin glaze layer 2 is formed on a relief surface 1R to a thickness which leaves recesses on the relief surface 1R. A glaze-repellent layer 4 capable of repelling the glaze slurry is then formed on the surface of the thin glaze layer 2 to form a coated substrate. The glaze slurry is affixed to the coated substrate for forming a glaze slurry layer 5 for completing the glazing.
