A hollow body includes a wall which at least partially surrounds an interior volume of the hollow body. The wall comprises a layer of glass comprising a first glass composition, comprises a base surface, and has a wall surface. The wall surface comprises at least one surface region, in which the base surface is at least partially superimposed by at least one elevated region, and at least one contact region, which extends along a contact range of a height of the hollow body. The at least one elevated region comprises a further glass composition. An exterior diameter of the hollow body has a maximum throughout the contact range. The at least one surface region is at least partially positioned in the at least one contact region.
