Abstract: A glass object having protrusions and/or recesses, for example a glass lid (1) with a handle (2), is produced in an IS machine by pressing molten glass from above in a mould with the cover of the mould, in a mould defined by said cover, by a shaping mould (11) and by a mouth mould (13) disposed under the shaping mould. When the glass lid is formed its handle projects downwards and lies in the mouth mould. SUbsequently the glass lid is transferred together with the mouth mould to the finishing mould (12) and is at the same time returned into a position in which the handle projects upwards in the finishing mould in which it is cooled supported by the finishing mould.

Abstract: The invention comprises a method for the continuous opalization of glass, wherein an opalescent agent is added to the molten glass in the forehearth situated between a glass furnace and the automatic forming machine, followed by adjustment of the glass temperature so that the opalescence takes place either before the automatic machine or at the latest, during the annealing which is carried out after the automatic machine.
