Method for further processing of a glass tube semi-finished product including thermal forming

A method for further processing a plurality of glass tube semi-finished products, comprising:

• providing the plurality of glass tube semi-finished products, wherein tube-specific data are provided at least one of on a data storage device, in a database and on each glass tube semi-finished product for each glass tube semi-finished product of the plurality of glass tube semi-finished products, and wherein each glass tube semi-finished product is marked with at least one marking associated with the tube-specific data of the respective glass tube semi-finished product;
• reading out the tube-specific data for the respective glass tube semi-finished product based on the at least one marking associated with the tube-specific data;
• and
• further processing the plurality of glass tube semi-finished products, the further processing including thermal forming carried out at least in sections, wherein at least one process parameter during the further processing of the respective glass tube semi-finished product of the plurality of glass tube semi-finished products is controlled as a function of the tube-specific data for the respective glass tube semi-finished product;
• wherein the tube-specific data comprise at least one of homogeneity of a glass melt which was used for tube shaping of the glass tube semi-finished product and process parameters for producing and processing the glass melt which was used for tube shaping of the glass tube semi-finished product.
