A method for homogenizing glass includes the method: providing a cylindrical blank composed of the glass having a cylindrical outer surface that extends along a longitudinal axis of the blank between a first end face and a second end face, forming a shear zone in the blank by softening a longitudinal section of the blank and subjecting it to a thermal-mechanical intermixing treatment, and displacing the shear zone along the longitudinal axis of the blank. To enable a radial mixing within the shear zone in addition to the tangential mixing with the lowest possible time and energy input, starting from this method, cylindrical sections of the blank are adjacent to the shear zone on both sides, the first cylindrical section having a first central axis and the second cylindrical section having a second central axis, the first central axis and the second central axis being temporarily non-coaxial with each other.

A device for producing glass products for primary pharmaceutical packaging is provided. The device includes a clamping chuck for clamping a glass product, a drive for driving the clamping chuck rotatingly about a longitudinal axis thereof, and a burner for heating a glass products received within the clamping chuck. The clamping chuck has a baffle structure for generating a gas current for cooling the clamping chuck when the clamping chuck is rotatingly driven about a longitudinal axis thereof while the glass product is heated above its softening temperature for hot-forming.

An integral homogeneous rod lens and the manufacturing thereof from a raw glass body are provided by melting the raw glass body in a mold, whereby a protruding part of the raw glass body deforms into a dome shape with a spherical or nearly spherical surface that defines a convex lens portion of the rod lens.

A coated glass package comprising a glass body having a Type 1 chemical durability according to USP 660, at least a class A2 base resistance or better according to ISO 695, and at least a type HGB2 hydrolytic resistance or better according to ISO 719. A lubricous coating having a thickness of 100 microns may be positioned on at least a portion of the exterior surface of the glass body. The portion of the coated glass package with the lubricous coating comprises a coefficient of friction that is at least 20% less than an uncoated glass package and the coefficient of friction does not increase by more than 30% after undergoing a depyrogenation cycle. A horizontal compression strength of the coated glass package is at least 10% greater than an uncoated glass package and the horizontal compression strength is not reduced by more than 20% after undergoing the depyrogenation cycle.

A method and apparatus are provided for producing a tube of glass by zonewise heating and softening of a hollow cylinder by a movable heating zone while rotating about its rotation axis. The glass tube is continuously formed by radial expansion of the softened region under action of centrifugal force and/or internal overpressure applied in the hollow-cylinder bore. The method and apparatus make it possible to deform the hollow cylinder in a single or a small number of forming steps into a glass tube having a larger outer diameter and high dimensional accuracy by determining a circumferential position at which the wall thickness is comparatively small, and during heating and softening of the rotating hollow cylinder a coolant is dispensed from a coolant source onto the deformation zone only when or predominantly when the circumferential position having the comparatively small wall thickness passes the coolant source.

A coated glass container having a Type 1 chemical durability according to USP 660 (2011), a class A2 base resistance or better according to ISO 695, and a type HGB2 hydrolytic resistance or better according to ISO 719. The glass body having an interior surface and an exterior surface. A lubricous coating having a thickness of <100 microns positioned on the exterior surface. The portion of the exterior surface with the coating having a coefficient of friction that is at least 20% less than an uncoated glass container formed from the same glass composition and does not increase by more than 30% after undergoing depyrogenation at about 260 C. for 30 minutes. A horizontal compression strength of the coated glass container is at least 10% greater than an uncoated glass container formed from the same glass composition and is not reduced by more than 20% after heat treatment at about 260 C. for 30 minutes.

A glass container for storing pharmaceutical formulations may include a glass body formed from a Type IA or Type IB glass composition according to ASTM Standard E438-92(2011). The glass body may include a wall portion with an inner surface and an outer surface, a heel portion and a floor portion, wherein the inner surface of the glass container is formed by the inner surface of the glass body. The glass body may include at least a class A2 base resistance or better according to ISO 695, at least a type HGB2 hydrolytic resistance or better according to ISO 719 and Type 1 chemical durability according to USP <660>. The glass container does not comprise a boron-rich layer on the inner surface of the glass body in as formed condition.
