Method and apparatus for ceramification of glasses, glass-ceramic article and its use

A process for the ceramizing of green glass, in particular in the form of a continuous green glass ribbon or individual green glass plates, - the green glass is transported on rollers, at least during the crystallization volume, - the entire ceramization at least a portion of the green glass between 0.5 and 4 hours long, wherein the at least a portion of the volume during crystallization of a maximum temperature for 5 to 60 minutes is exposed, - the volume crystallization is carried out in a temperature range between 750 and 1250 ° C, wherein the temperature of the top and bottom of the at least one ceramic-forming portion of the green glass is measured continuously and the heating is controlled by means of this information based on setpoint values ​​by means of a measuring and control device , and - 10 to 10 -. The at least one portion of the volume during crystallization at a feed rate that between 0.2 and 10 m / min, preferably between ...
