The present invention relates to a method capable of easily manufacturing a curved thin glass sheet and a curved joined glass sheet to which functionality is added.

A glass plate includes a first surface provided with a first film; and a second surface provided with a second film and opposite to the first surface. Each of the first film and the second film includes mainly tin oxide and has a sheet resistance value of 20 Ω/□ or less. When film thicknesses of the first and second films are θ.sub.1 nm and θ.sub.2 nm respectively, and when, in the glass plate, a haze value measured from the first surface side for a configuration provided with the first film only is H.sub.1 (%), and a haze value measured from the second surface side for a configuration provided with the second film only is H.sub.2 (%), a value of θ.sub.1 divided by H.sub.1 is 500 or more but 1200 or less, and a value of θ.sub.2 divided by H.sub.2 is 300 or more but 750 or less.

The present disclosure relates to products and methods for modifying the reflection of a light source in a fireplace and other products.

The low-reflection coating of the present invention is adapted to be provided on at least one principal surface of a substrate. The low-reflection coating is a porous film having a thickness of 80 to 800 nm, the porous film including: fine silica particles being solid and spherical and having an average particle diameter of 80 to 600 nm; and a binder containing silica as a main component and containing a hydrophobic group, the fine silica particles being bound by the binder. The low-reflection coating contains 35 to 70 mass % of the fine silica particles, 25 to 64 mass % of the silica of the binder, and 0.2 to 10 mass % of the hydrophobic group of the binder. The low-reflection coating produces a transmittance gain of 1.5% or more when provided on the substrate.

One or more aspects of the disclosure pertain to an article including a film disposed on a glass substrate, which may be strengthened, where the interface between the film and the glass substrate is modified, such that the article has an improved average flexural strength, and the film retains key functional properties for its application. Some key functional properties of the film include optical, electrical and/or mechanical properties. In one or more embodiments, the interface exhibits an effective adhesion energy of about less than about 4 J/m.sup.2. In some embodiments, the interface is modified by the inclusion of a crack mitigating layer containing an inorganic material between the glass substrate and the film.

Insulated glazing units comprising first and second sheets of glazing material with a low pressure space there between are described. The major surface of the second sheet of glazing material not facing the low pressure space has a low emissivity coating comprising at least one layer of fluorine doped tin oxide thereon. There is a first anti-iridescence coating between the low emissivity coating and the second sheet of glazing material. Also described are insulated glazing units comprising three (first, second and third) sheets of glazing material with a low pressure space between first and second sheets of glazing material, and a second space between the first and third sheets of glazing material. There is a low emissivity coating on one or both major surfaces facing the low pressure space. The third sheet of glazing material has a low emissivity coating on both opposed major surfaces thereof.

A method of reducing the emissivity of a coated glass article includes the following steps in sequence: (a) forming a coated glass article, the coated glass article comprising a glass substrate and a coating formed on the glass substrate, the coating having a first layer deposited over the glass substrate and a second layer, the second layer being provided between the first layer and the glass substrate, wherein the coated glass article exhibits a first emissivity; and (b) heating the coated glass article in an environment set to a predetermined temperature and for a predetermined period of time. After step (b), the coated glass article exhibits a second emissivity, the second emissivity being less than the first emissivity.

A process for the preparation of an antimicrobial coating solution is described. The process comprises the steps of: (i) mixing a chelating agent with titanium alkoxide and fluoroacetic acid; and (ii) adding an aqueous solution to the mixture from step (i). The antimicrobial coating described is visible light activated. The coating is applied to surfaces and then heat treated to form a transparent layer on the surface. This is particularly advantageous where the surface is glass.
