The invention relates to a method for producing glass or vitroceramic materials having increased strength. For this purpose, the method for producing glass or vitroceramic articles comprises the following steps: producing an initial glass body (11), storing the initial glass body (11) on a gas cushion (13) between a levitation support (1) and the initial glass body (11), and at least partially ceramizing the initial glass body (11) on the levitation support (1). The levitation support comprises at least one continuous surface area (3) having at least one gas supply area (151, 152, 153) to which levitation gas destined for the gas cushion (13) is supplied, and at least one gas discharge area (171, 172, 173) where gas originating from the gas cushion (13) is at least partially carried off.

The invention relates to a method and a device for producing coloured glasses. The aim of the invention is to obtain a particularly intimate mixture and to enable a quick change of the melt at the same time. To this end, the following procedure steps are applied: a melt made of a compound or fragments of glass is produced, the glass melt is further processed in at least one additional vessel, the melt is supplied to a skull device (3) (skull pot or skull channel) during subsequent processing, a dye is supplied (6, 6.1) to the melt after the melt was in the melting station (1) but before the melt enters the skull device (3) or while said melt is in the skull device.

The aim of the invention is to reduce the energy required for melting in a unit provided with cooled walls. According to the invention, a method is provided for melting inorganic materials in a skull crucible, wherein the temperature of at least one area of the melt is selected in such a way that it ranges from Teff -20 % to Teff +20 %. The temperature Teff is defined by the temperature at which energy consumption per weight unit of melt is at a minimum. The through-put rate is selected in such a way that it is adapted to the required residence time.
