Beschreibung
Zusammenfassung:	A method for producing glass vials, in particular pharmaceutical vials or pharmaceutical ampoules, from a glass tube is specified, said method having the following steps of: (a) rotating the glass tube (10) about the longitudinal axis (12) thereof; (b) locally heating the glass tube (10) from one side by means of at least one burner to at least the softening temperature (EW) of the glass; (c) reducing the diameter by pressing at least one shaped part (28a) laterally against the heated region (16); and (d) separating the glass tube by means of a burner (14). A glass vial produced in such a way releases a reduced amount of alkali in accordance with ISO 4802 and has a decreased delamination tendency. Furthermore, in the hot-formed peripheral region, the alkali content is only slightly reduced compared with the alkali content in the glass interior.
