Abstract

The invention relates to a method and device for non-contact molding of fused glass or glass ceramic gobs by means of gas levitation, comprising the following method steps: a pre-form is generated, the pre-form is brought close to a molding tool, which may be connected to a compressed gas source on the open-pored region thereof facing the pre-form in order to generate a gas cushion between the molding tool and the pre-form and the molding tool is directly heated at least during a part of the molding phase.
