Abstract

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.
