The invention relates to 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 ~C, notably at between 20 and 1705 ~C. The invention is characterized in that 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.
L'invention concerne un procédé permettant de chauffer de manière homogène des verres et/ou des vitrocéramiques semi-transparents et/ou transparents à l'aide de rayons infrarouges, les verres et/ou vitrocéramiques étant soumis à une traitement thermique à une température comprise entre 20 et 3000 ·C, notamment entre 20 et 1705 ·C. L'invention se caractérise en ce que l'opération de chauffage intervient par une partie des rayons infrarouges qui agissent directement sur les verres et/ou les vitrocéramiques, ainsi que par une partie des rayons infrarouges qui agissent indirectement sur les verres et/ou les vitrocéramiques. La partie de rayons qui agissent indirectement sur le verre et/ou les vitrocéramiques représente plus de 50 % du rendement total des rayons.
