A glass-ceramic cooktop is provided that is made of glass-ceramic material with a flat upper side and an underside. The glass-ceramic material has transmittance values of greater than 0.1% in the visible light range in the total wavelength region greater than 420 nm, a light transmittance in the visible range of 0.8-2.5%, and a transmittance of 0-85% in the infrared at 1600 nm, and wherein the glass-ceramic material has high quartz mixed crystals as the prevalent crystal phase. The underside is flat, unstructured, and coplanar with the upper side.

A transparent, colorless glass or glass-ceramic panel has a visually dense, high-temperature-stable coating having an organic/inorganic network structure containing filling material particles and a color-imparting pigment. The mechanically stable, visually dense coating has no melt-reaction zone at the surface of the panel, which is coated with the coating, so that it does not impair the panel strength. The inorganic network structure can be made from a SiO-based sol. The coating is made by introducing the color-imparting pigment and the filling material particles into a reactive organic/inorganic network structure; applying the resulting organic/inorganic network structure containing the pigment and the filling material particles to the panel to coat the panel and then burning-in the organic/inorganic network structure with the pigment and the filling material particles under thermal conditions to form the coating with no melt-reaction zone.

A roller table for supporting and transporting a hot glass strand. A plurality of rollers arranged parallel to each other and perpendicular to the transport direction of the glass strand are capable of being selectively rotated in the direction of transport of the glass strand. At least some of the rollers are sleeves, the casings of which are which are gas-permeable on at least a portion of their surfaces and the casings are provided with a supply of pressurized gas which is emitted through the openings of the gas-permeable surfaces.
