A method for the homogeneous heating of semitransparent and/or transparent glass and/or glass-ceramic articles using infrared radiation so that the glass and/or glass-ceramic articles undergo heat treatment at between 20 and 3000&#xb0; C., notably at between 20 and 1705&#xb0; C. Heating is achieved by a component of infrared radiation which acts directly on the glass and/or glass-ceramic articles and by a component of infrared radiation which acts indirectly on said glass and/or glass-ceramic articles. The radiation component indirectly acting on the glass and/or glass-ceramic articles accounts for more than 50% of total radiation output.

Method and device for the homogenous heating of glass and/or glass-ceramic articles using infrared radiation

The invention relates to a method of producing glass-ceramic parts and/or glass parts by deformation of a glass-ceramic blank and/or glass blank. The invention is characterized in that forming is carried out using infrared radiation.
