Method and apparatus for ceramification of the starting glass of a glass ceramic as well as uses of methods and apparatus

A process for the ceramizing a starting glass of a glass ceramic comprising at least the following steps: 1.1 the starting glass is heated from an initial temperature T 1.2 the glass is to precipitate nuclei at the temperature T 1.3 the glass is further heated to a temperature T 1.4 the glass is held for 1.5 the control of the temperature profile takes place by means of a control loop comprising at least one temperature sensor for sensing the temperature and a heating system as an actuator, characterized, in that 1.6 the heating IR radiators to heat the glass to ceramic-forming with ...
