Title: METHOD AND DEVICE FOR ANNEALING FLAT BODIES
Abstract:
The invention relates to a method for annealing flat bodies, especially flat bodies consisting of an amorphous, inorganic material, especially flat glass panes or glass ceramic panes. One or more of the flat bodies are subjected to a heat treatment within a temperature range between room temperature and the respective glass transition temperature. The invention is characterized in that said heat treatment is carried out in an annealing container and in that said annealing container is configured in such a way that it is closed sufficiently to prevent impurities from the environment surrounding the annealing container from coming into contact with the flat body.
