In embodiments, a conveyor apparatus can include a conveyor ribbon having a length, a width, a thickness less than the width, and a plurality of receiving apertures located along the length and extending through the thickness of the conveyor ribbon. The plurality of receiving apertures are dimensioned to receive and hold a plurality of glass articles. A conveyor drive and guidance system directs the conveyor ribbon along a predefined conveyor path. The predefined conveyor path can include an immersion section and a drain section. The immersion section can be oriented to direct the conveyor ribbon into and out of an immersion station and the conveyor ribbon is rotated about a horizontal axis in the drain section after being directed out of the immersion station.

The present invention relates to a glass in which: the glass is a crystallized glass; the glass has a difference log η−log η.sub.0 (dPa.Math.s) between a logarithm log η (dPa.Math.s) of bulk viscosity η (dPa.Math.s) and a logarithm log η.sub.0 (dPa.Math.s) of local viscosity η.sub.0 (dPa.Math.s) of larger than 0 and 1.8 or smaller, in a temperature range in which the logarithm log η.sub.0 (dPa.Math.s) of the bulk viscosity η (dPa.Math.s) is 11.4 or larger and 12.7 or smaller.

The present disclosure relates to fusion formable highly crystalline glass-ceramic articles whose composition lies within the SiO.sub.2—R.sub.2O.sub.3—Li.sub.2O/Na.sub.2O—TiO.sub.2 system and which contain a silicate crystalline phase comprised of lithium aluminosilicate (β-spodumene and/or β-quartz solid solution) lithium metasilicate and/or lithium disilicate. Additionally, these silicate-crystal containing glass-ceramics can exhibit varying Na.sub.2O to Li.sub.2O molar ratio extending from the surface to the bulk of the glass article, particularly a decreasing Li.sub.2O concentration and an increasing Na.sub.2O concentration from surface to bulk. According to a second embodiment, disclosed herein is a method for forming a silicate crystalline phase-containing glass ceramic.

A strengthened glass container or vessel such as, but not limited to, vials for holding pharmaceutical products or vaccines in a hermetic and/or sterile state. The strengthened glass container undergoes a strengthening process that produces compression at the surface and tension within the container wall. The strengthening process is designed such that the tension within the wall is great enough to ensure catastrophic failure of the container, thus rendering the product unusable, should sterility be compromised by a through-wall crack. The tension is greater than a threshold central tension, above which catastrophic failure of the container is guaranteed, thus eliminating any potential for violation of pharmaceutical integrity.

The present invention is based, at least in part, on the identification of a pharmaceutical container formed, at least in part, of a glass composition which exhibits a reduced propensity to delaminate, i.e., a reduced propensity to shed glass particulates. As a result, the presently claimed containers are particularly suited for storage of pharmaceutical compositions and, specifically, a pharmaceutical solution comprising a pharmaceutically active ingredient, for example, PEDIARIX® (Diphtheria and Tetanus Toxoids and Acellular Pertussis Adsorbed, Hepatitis B (Recombinant) and Inactivated Poliovirus Vaccine), HAVRIX® (Hepatitis A Vaccine), ENGERIX-B® (Hepatitis B Vaccine (Recombinant)), TWINRIX® (Hepatitis A & Hepatitis B (Recombinant) Vaccine), EPERZAN® (albiglutide), MAGE-A3 Antigen-Specific Cancer Immunotherapeutic (astuprotimut-R), GSK2402968 (drisapersen), and HZ/su (herpes zoster vaccine).

The invention relates to a glass sheet having a boron-, strontium- and lithium-free glass composition comprising the following in weight percentage, expressed with respect to the total weight of glass: 65≦SiO.sub.2≦78%; 8≦Na.sub.2O≦15%; 1≦K.sub.2O<6%; 1≦Al.sub.2O.sub.3<6%; 2≦CaO<10%; 0≦MgO≦6%; as well as a K.sub.2O/(K.sub.2O+Na.sub.2O) ratio which is ranging from 0.1 and 0.7. The invention corresponds to an easy chemically-temperable soda-lime-silica type glass composition, which is more suited for use in electronic devices applications.
