Abstract

A cooking surface for a cooktop. Encrusted, spilled, or overflowing food is deposited on the cooking surfaces of cooktops during cooking and the removal of such residue is difficult because the surface of a cooktop is typically rough and uneven. The invention teaches the manufacture of an easy-to-clean glass ceramic cooktop from a floated glass ceramic. As a result of the increased use of controls in cooking devices, an increased number of displays are also being used under the surface of the cooktops. The invention provides a cooktop with a smooth, distortion-free surface that is easy to clean. The invention also relates to window panes for enclosed hot areas with high temperatures, which are typically made of transparent glass ceramic. When used as windows in warming stoves or in self-cleaning ovens, combustion residues are thereby deposited on the windows, which residues must then be removed. It is difficult to clean a window of this type, because the surface of the transparent glass ceramic that is manufactured using conventional methods is typically structured and uneven. The invention teaches the manufacture of an easy-to-clean class ceramic window body from a floated glass c…
