  • Publication number: 20190160788
    Abstract: 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.

  • Patent number: 8443628
    Abstract: The present invention relates to a method for manufacturing a non-planar product in glass-ceramic. Said method comprises the following steps: (i) in a conventional furnace (3), heating a sheet of precursor glass of said glass-ceramic, so that said sheet becomes formable while avoiding its ceramming; (ii) forming said heated sheet; (iii) cooling said formed sheet (2b); (iv) ceramming said formed, cooled sheet.

  • Publication number: 20110067450
    Abstract: An apparatus for making shaped articles includes a container having at least one vacuum port and a surface for receiving a sheet of glass-based material. At least one positive mold is supported in the container, where the at least one positive mold has an exterior surface including a profile defining an interior of a shaped article. An open volume is defined between the container and the at least one positive mold and is in communication with the vacuum port.
