Methods of manufacturing electrochromic windows are described. Insulated glass units (IGU's) are protected, e.g. during handling and shipping, by a protective bumper. The bumper can be custom made using IGU dimension data received from the IGU fabrication tool. The bumper may be made of environmentally friendly materials. Laser isolation configurations and related methods of patterning and/or configuring an electrochromic device on a substrate are described. Edge deletion is used to ensure a good seal between spacer and glass in an IGU and thus better protection of an electrochromic device sealed in the IGU. Configurations for protecting the electrochromic device edge in the primary seal and maximizing viewable area in an electrochromic pane of an IGU are also described.

Methods of manufacturing electrochromic windows are described. An electrochromic device is fabricated to substantially cover a glass sheet, for example float glass, and a cutting pattern is defined based on one or more low-defectivity areas in the device from which one or more electrochromic panes are cut. Laser scribes and/or bus bars may be added prior to cutting the panes or after. Edge deletion can also be performed prior to or after cutting the electrochromic panes from the glass sheet. Insulated glass units (IGUs) are fabricated from the electrochromic panes and optionally one or more of the panes of the IGU are strengthened.

An enameled substrate includes a first glass sheet including, on a first main face, a scattering layer made of scattering enamel, including a vitreous matrix, the scattering layer including a first pattern having a width of at least 0.1 mm and a surface S0, the first pattern including a set of separate micropads of the scattering enamel, wherein, by defining within the first scattering pattern an analysis surface area S1 of less than S0, S1 being at least 50 m by 50 m and at most 100 m by 600 m, and a surface area S2 which is a sum of the surface areas of the micropads in the surface area S1, the first scattering pattern is defined by an equivalent mean diameter Am of the micropads of less than 10 m and of at least 1 m.

A method for producing a glass article is provided. The method for producing a glass article, the method including preparing a glass to be processed, the glass comprising a glass bulk and a low-refractive surface layer disposed on the glass bulk, and etching away the low-refractive surface layer to form an etched glass, wherein the etching away the low-refractive surface layer comprises: cleaning the low-refractive surface layer with an acid solution; and cleaning the low-refractive surface layer with a base solution after the cleaning it with the acid solution.

A method of preparing a glazing, comprising: stacking a first glass sheet, a first interlayer, a photopolymer film, a second interlayer, and a second glass sheet to provide a lamination stack; deairing the lamination stack; autoclaving the lamination stack to provide a laminated glazing; applying a reactive light to the photopolymer film in the laminated glazing, wherein reactive light is applied to the laminated glazing through a master holographic film; and bleaching the laminated glazing such that the photopolymer film is no longer reactive to light exposure.

The present invention is a windshield for an automobile on which an information acquisition device configured to acquire information from the outside of a vehicle by emitting and/or receiving light can be arranged. The windshield includes: a laminated glass including an information acquisition region that is opposite to the information acquisition device and through which the light passes; and an antifog sheet in which at least a sticky layer, a substrate film, and an antifog layer are layered in this order, the sticky layer being attached to at least a surface on a vehicle interior side of the information acquisition region. The laminated glass includes at least one glass plate in which surface concentrations of tin oxide in two principal surfaces are different, and a surface of the glass plate in which the concentration of tin oxide is higher faces the vehicle interior side.
