A catalyst includes a gas-permeable textile sheet material made of noble-metal-containing wire having a three-dimensional secondary structure produced thereon. The secondary structure is a three-dimensional dent structure including dents arranged adjacent to each other in rows in two spatial directions. The dents are in the form of a hexagon. The dent structure is formed by self-organization in a denting process.

A bright noble metal preparation for firing on ceramic/porcelain surfaces at a minimum temperature of 900&#xb0; C. The preparation has at least one organic noble metal compound including at least one of an organic gold, platinum, silver and palladium compound, at least one flux that consists of organometallic compounds including Cr in the form of at least one organic compound, such that a Cr content is 0.01 to 1.0 mole per mole of noble metal, and at least one vehicle. The bright noble metal preparation is rhodium-free and has a noble metal content of 6 to 20 wt. %, based on the preparation.

The cook top includes a colorless transparent glass ceramic plate, which is provided with an opaque coating extending over its underside, except that in at least one window area a window coating is provided on the underside of the glass ceramic plate area instead of the opaque coating. In order to optimize colored displays arranged under the at least one window area and to facilitate the use of capacitive touch sensors, the window coating is a burned-in noble metal preparation with an electrical surface resistance of 1 M&#x3a9;/&#x25a1; and in the at least one window area the glass ceramic plate coated with the window coating has a transmission in a range from 1.0 to 21.0% and a light scattering in a range of from 0.0 to 1.0% for visible light with wavelengths of from 400 nm to 750 nm.

The glass ceramic plate for a cooking apparatus is transparent to visible light and IR radiation and has a noble metal film on its underside. The noble metal film is composed of an alloy of gold, platinum and/or palladium, which imparts a reflective property to it. It contains from 0 to 5 percent by weight, in relation to a total metal content, of silver, copper, silicon, bismuth and other metals that are not noble metals. The glass ceramic plate coated with the noble metal film has a spectral transmission of 0 to 12% in the infrared region of the spectrum. When a decoration consisting of a grid of unsymmetrically distributed elements is provided on the topside of the glass ceramic plate, defects in the glass ceramic material can be concealed. The invention also includes a method of coating.
