A method for producing a glass article having high hydrolytic resistance is provided. A glass tube consisting of borosilicate glass and having an Al.sub.2O.sub.3 content of less than 1 weight-%, a ZrO.sub.2 content of 2-12 weight-%, and a glass transition temperature T.sub.g is reshaped into a glass article and is subsequently subjected to a thermal post-treatment. To reduce the alkali release of the glass article, the glass article is subjected to a treatment temperature of T.sub.B≥T.sub.g+5° K over a treatment time of t.sub.B≥5 min and is subsequently cooled during the thermal post-treatment.

Systems for producing articles from glass tube include a converter having a base with a plurality of processing stations and a turret moveable relative to the base. The turret indexes a plurality of holders for holding the glass tubes successively through the processing stations. The systems further include a gas flow system or a suction system for producing a flow of gas through the glass tube during one or more heating, forming, separating or piercing operations. The flow of gas through the glass tube produced by the gas flow system or suction system may be sufficient to evacuate or purge volatile constituents of the glass from the glass tube and/or pierce a meniscus formed on the glass tube during separation, thereby reducing the Surface Hydrolytic Response (SHR) of the interior surface of the glass tube and articles made therefrom.

The invention relates to a method for producing a glass container, such as a glass syringe or a glass ampule, having a form-specific dispensing portion and optionally a form-specific counter support, from a glass container blank, wherein the basis weight of the glass container blank is detected indirectly or directly and the overall longitudinal extent of the glass container to be produced is determined on the basis of the detected basis weight.

Methods for producing glass articles from laminated glass tubing include introducing the glass tubing to a converter. The glass tubing includes a core layer under tensile stress, an outer clad layer under, and an inner clad layer. The methods include forming a feature the glass article at a working end of the laminated glass tubing and separating a glass article from the working end of the laminated glass tubing, which may expose the core layer under tensile stress at the working end of the glass tubing. The method further comprises remediating the exposed portion of the core layer by completely enclosing the core layer in a clad layer. Systems for re-cladding the exposed portion of the core layer as well as glass articles made using the systems and methods are also disclosed.

In a fabricating method for a quartz vial having a body part for containing a substance, a bottom part closing a lower end of the body part, a cylindrical neck part disposed at an upper end of the body part, a cylindrical mouth part disposed above the neck part and having an outer diameter larger than that of the neck part, and a tapered portion connecting the mouth part and the neck part to each other, outer peripheral surfaces of the tapered portion and the neck part are formed by shaving, and the body part that is separately fabricated is welded to the neck part. Thus, quartz vials having a predetermined shape can be mass-fabricated.

An apparatus for forming a housing cone of a needle in a syringe body of a glass syringe is provided. The apparatus has a forming tool configured to make a hole for creating the housing cone, and a lubricant-coolant liquid dispensing device. The forming tool has a grip portion, a tip, and a tip body, interposed between the tip and the grip portion, suitable for making the hole. The grip portion, the tip body and the tip are in one piece and aligned along a prevailing extension axis. The tip body, with respect to a cross-sectional plane perpendicular to the prevailing extension axis, has a non-circular cross section, inscribed within the maximum circle having as its radius the maximum distance between a point of the cross section and the prevailing extension axis, measured on the cross-sectional plane.
