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.

A method of manufacturing a glass container in preparation for direct digital printing includes forming a glass container having a glass wall and applying a primer coating to the glass container. The primer coating is applied by directing an atomized spray of an aqueous primer composition onto the glass container over an adherent base layer, such as a hot-end coating, which deposits the primer coating, followed by heating the primer coating with a heat source such as a flame. Upon being heated, the clarity of the primer coating is increased. As a result, a decorative marking may be printed onto the glass container without having to pretreat the glass container in a way that involves pyrolytically depositing a layer of silicon dioxide onto the glass container prior to printing.

A method for improving the efficiency of a pharmaceutical filling line by running the filling line at an increased throughput rate is disclosed. The method involves using glass vials that have been strengthened and coated to reduce the coefficient of friction of the outer surface of the vials with a pharmaceutical filling line set at a rate greater than or equal to 600 vials per minute and miming in an efficiency of at least 70%. In other embodiments of the invention, the pharmaceutical filling line may also be provided with a polymer chemical coating at points of contact with the glass vials, thereby further reducing the friction between the vials and the points of contact and the effects of impact of the vials with contact points of the pharmaceutical filling line.

Embodiments described herein may be related to apparatuses, processes, and techniques directed to a protective coating for an edge of a glass layer, in particular a glass core within a substrate of a package, where the protective coating serves to protect the edge of the glass core and fill in cracks at the edges of the glass. This protective coating will decrease cracking during stresses applied to the glass layer during manufacturing or operation. Other embodiments may be described and/or claimed.
