Abstract
The method of supporting and transporting hot flat glass on a gas bed for ceramicizing includes arranging a number of spaced-apart porous or perforated planar segments to form a base with a gas-permeable support surface so that slits, which are narrower than the planar segments, are formed between them, forcing gas through the porous or perforated planar segments and conducting the gas away through the slits between them so as to form the gas bed with no static pressure zones and with a parabolic pressure distribution and producing a predetermined temperature profile for ceramicizing through which the hot flat glass is transported on the gas bed without deformation and without any contact between it and the base. The resulting glass ceramic has smoother surfaces without pits or deformations.
