Zusammenfassung:A method for thermally treating an annular region of an inner surface of a glass container produced from a borosilicate glass tube is provided. The annular region is disposed at a tubular portion of the glass container and is disposed adjacent to a glass container bottom. The method includes: forming the glass container bottom from the glass tube; heating the annular region of the inner surface of the tubular portion to a treatment temperature TBeh above the transformation temperature TG, wherein the annular region is adjacent to the glass container bottom; maintaining the treatment temperature TBeh for a certain time period; and cooling the glass container to room temperature.
