A reforming mandrel and a method of use reforming mandrel to reform glass are described. The reforming mandrel comprises an upstream portion, a downstream portion and an at least partially hollow interior. The upstream portion may have an intake inlet for fluid flow. The downstream portion may be axially spaced from the upstream portion. The downstream portion may have a flattened cross-section defined by flattened peripheral portions joined by curved peripheral portions. At least one curved peripheral portion may be made of porous material resistant to a temperature of at least 1000 C. The at least partially hollow interior may communicate with the intake inlet and the porous material.

The glass containers described herein have at least two performance attributes selected from resistance to delamination, improved strength, and increased damage resistance. In one embodiment, a glass container may include a body having an inner surface, an outer surface and a wall thickness extending between the outer surface and the inner surface. A compressively stressed layer may extend from the outer surface of the body into the wall thickness. The compressively stressed layer may have a surface compressive stress greater than or equal to 150 MPa. A lubricous coating may be positioned around at least a portion of the outer surface of the body. The outer surface of the body with the lubricous coating may have a coefficient of friction less than or equal to 0.7.

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.

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 regarding origin and manufacture of the glass tube semi-finished product and a second marking, the information of which second marking is linked to the information of the first marking, so as to enable a determination regarding authenticity of the glass tube semi-finished product, origin of the glass tube semi-finished product, and/or origin of an apparatus with which the first and/or second marking was generated on the glass tube semi-finished product. The first marking is a marking that is produced at temperatures above the transformation temperature of the glass in a counterfeit-proof manner. The combination of two markings provides a high level of protection against counterfeiting.

A method for further processing of a glass tube semi-finished product includes: providing the glass tube semi-finished product, along with tube-specific data for the glass tube semi-finished product; reading the tube-specific data for the glass tube semi-finished product; and further processing of the glass tube semi-finished product including a step of thermal forming carried out at least in sections. At least one process parameter during the further processing of the glass tube semi-finished product including the step of thermal forming carried out at least in sections is controlled as a function of the tube-specific data for the glass tube semi-finished product. In this way, the further processing can be matched more efficiently to the particular characteristics of a glass tube semi-finished product to be processed or a particular subsection thereof, and the relevant characteristics of the particular glass tube semi-finished product do not need to be measured again.

A method for further processing a glass tube semi-finished product includes: providing the glass tube semi-finished product, along with defect data for the glass tube semi-finished product; reading the defect data for the glass tube semi-finished product; and further processing the glass tube semi-finished product, for example by cutting to length or sorting out. The further processing of the glass tube semi-finished product is adapted to the defect data, which were read out for the glass tube semi-finished product. In this way, the further processing can be more efficiently adapted to the respective characteristics of a glass tube semi-finished product to be processed or a specific sub-section thereof, and the relevant defects of the respective glass tube semi-finished product do not need to be determined or measured again.

A glass container comprises a glass body comprising a first region under a compressive stress extending from a surface of the glass body to a depth of compression and a second region extending from the depth of compression into a thickness of the glass body, the second region being under a tensile stress. The glass container also includes a localized compressive stress region having a localized compressive stress extending from the surface to a localized depth of compression within the body. The localized depth of compression is greater than the depth of compression of the first region. The glass container also includes a crack re-direction region extending in a predetermined propagation direction, wherein the crack re-direction region possesses a higher tensile stress than the tensile stress in the second region in a sub-region of the crack re-direction region, the sub-region extending substantially perpendicular to the predetermined propagation direction.
