  • Publication number: 20200399173
    Abstract: Methods of manufacturing a glass-based article comprise: after mechanical polishing of a glass-based substrate, treating at least one surface of the glass-based substrate for protection of the at least one surface from contamination and/or for removal of contaminants from the at least one surface by a treatment other than ultrasonic cleaning; and exposing the glass-based substrate to an ion exchange treatment after the treating step to form the glass-based article. The treating step includes: exposing the at least one surface to a high pH soaking for removal of contaminants; deionizing the at least one surface for removal of contaminants; and/or applying a temporary coating to the at least one surface for protection of the at least one surface from contamination, and removing the temporary coating prior to the ion exchange treatment step. The ion exchange treatment may comprise a molten salt bath having an increased pH and temperature.

  • Publication number: 20180327297
    Abstract: A method for producing a glass article includes forming a glass sheet from a molten glass source and separating the glass article from the glass sheet. During the step of separating the glass article from the glass sheet, the water content of the atmosphere surrounding the glass sheet is controlled to be below a predetermined value. Such control of the water content of the atmosphere surrounding the glass article can effectively reduce the density of particles adhered thereto.

  • Patent number: 9884782
    Abstract: A patterned article and a method of making the patterned article. The patterned article comprises a glass substrate and black matrix segments. The black matrix segments are in the form of a pattern and at least one of the segments has a line width of 8 ?m or less. The article also comprises an adhesion agent positioned between the glass substrate and the black matrix segments. The adhesion agent provides at least one of: a total surface energy of 65 mN/m or less and at least a 30% reduction in surface polarity compared to a control untreated glass surface as determined by H2O and diiodomethane contact angle and application of the Wu model.
