Abstract:
1. A method for the homogeneous heating of semi-transparent and/or transparent glass articles and/or glass-ceramic materials using infrared radiation emitted by IR radiators, whereby a glass article and/or glass-ceramic material is subjected to a heat treatment in the range from 20° C. to 3000° C. characterized in that the heating is achieved by a component of infrared radiation acting directly on the glass article and or the glass-ceramic material as well as a component of infrared radiation acting indirectly on the glass article and/or glass-ceramic material, in which the component of the radiation acting indirectly on the glass material and/or the glass-ceramic materials amounts to more than 50% of the total radiation output emitted by IR radiators, and wherein the radiation is a shortwave infrared radiation with a color temperature higher than 1500 K.
