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.
