Beschreibung
Zusammenfassung:	A glass tube semi-finished product or a hollow glass product manufactured from the glass tube semi-finished product is provided with a first marking with information on the origin and/or tube-specific production data of the glass tube semi-finished product, which marking is read from the hollow glass product after its manufacture to determine the origin and/or the tube-specific production data of the glass tube semi-finished product, e.g., to identify the semi-finished glass tube from which the hollow glass product has been made, and/or trace the tube-specific production data of this glass tube semi-finished product. This means that the entire supply chain for the hollow glass product from the supplier of the originally used glass tube semi-finished product up to the end product can be determined. The physical and chemical characteristics of the glass tube semi-finished product are not altered for producing the first marking.
