  • Patent number: 7049003
    Abstract: This invention relates to a method of making a laminated window such as a vehicle windshield. At least one of the two glass substrates of the window is ion beam milled prior to heat treatment and lamination. As a result, defects in the resulting window and/or haze may be reduced.
    Type: Grant
    Filed: December 16, 2003
    Date of Patent: May 23, 2006

  • Patent number: 6808606
    Abstract: This invention relates to a method of making a window (e.g., vehicle windshield, architectural window, etc.), and the resulting window product. At least one glass substrate of the window is ion beam treated and/or milled prior to application of a coating (e.g., sputter coated coating) over the treated/milled substrate surface and/or prior to heat treatment. As a result, defects in the resulting window and/or haze may be reduced. The ion beam used in certain embodiments may be diffused. In certain embodiments, the ion beam treating and/or milling is carried out using a fluorine (F) inclusive gas(es) and/or argon/oxygen gas(es) at the ion source(s). In certain optional embodiments, F may be subimplanted into to treated/milled glass surface for the purpose of reducing Na migration to the glass surface during heat treatment or thereafter, thereby enabling corrosion and/or stains to be reduced for long periods of time.

  • Patent number: 6498118
    Abstract: A glass composition employing as its colorant portion at least iron (total iron expressed as Fe2O3), erbium (e.g., Er2O3), and holmium (e.g., Ho2O3). The glass may be grey or otherwise colored in different embodiments. In certain example embodiments the colorant portion may include, by weight percentage: Ingredient wt. % total iron: 0.10-0.90% erbium oxide: 0.20-2.50% selenium:   0.0-0.0020% cobalt oxide:   0.0-0.0050% titanium oxide: 0.0-2.0% boron oxide: 0.0-2.0% holmium oxide: 0.10-1.60% thulium oxide: 0.0-2.0% ytterbium oxide: 0.0-3.0% lutetium oxide:  0.0-1.0%.
