A bottle cutter apparatus, systems and methods of using the same are provided. Specifically, the bottle cutter apparatus comprises a stage for holding a bottle and a rotatable arm having a blade thereon for scoring a glass bottle, or any glass tubular item. The stage is modular and movable, thereby accommodating different sized bottles thereon for precise scoring with the arm and blade.

A method and apparatus for producing glass products from tubular glass precursors is provided. In particular, a method and apparatus for separating tube glass into sized glass tube portions, produced glass tube portions, glass precursor portions, or glass product portions, and their use as pharmaceutical packaging are provided. The tube glass or the glass precursor or the glass product is provided with filaments along predetermined breaking planes. The filaments extend obliquely to the local wall radius and allow for clean separation of the tube glass or the glass precursor or the glass product.

Provided is an expandable device for fracturing a container for liquids, for example beverages, in particular alcoholic beverages, made of glass or a similar material, wherein the device has a first retracted position according to which the device can be accommodated at least partially in a recess at a bottom section of the container without causing fracture to the container and a second extended position according to which the device is able to cause a fracture at a bottom section of the container by impact against a solid surface such as a table, with the aim to prevent reuse or recycle of the container, for example with adulterated beverages.

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.
