    摘要: The present invention relates to a method for hard coating glass containers comprising the steps of: Providing a heated glass container; Applying a coating composition on the outer surface of the heated glass container; Annealing the applied coating composition onto the outer surface of the heated glass container to obtain a coated glass container; wherein the coating composition comprises a metal and/or metalloid alcoholate, such as an alcoholate of titanium(IV), zirconium (IV), aluminium (III), tantalum (V), silicon (IV) and/or germanium (IV), in a solvent with a boiling point above 90° C., a coated glass container coated with the method as described above or below and the use of a coating composition comprising a metal alcoholate in a solvent with a boiling point above 90° C. for increasing the hardness of a coated glass container.
