A method for producing an automotive glazing with an optical sensor device, with the glazing having superior optical qualities, including the steps of applying an enamel obscuration mask on at least one face of at least one glass sheet, where the obscuration mask extends to an area where the at least one optical sensor device will be fixed and includes at least one opening on the automotive interior side so as to be capable of acquiring information through the opening from the optical sensor device intended to be fixed at the at least one opening; drying or firing the enamel obscuration mask; applying a washable cover layer resisting at a temperature of at least 620° C. on the surface of the at least one opening; submitting the glass sheet to a heat treatment above 450° C. during a bending or tempering process; and removing by washing the washable cover layer.

A method of manufacturing a reinforced cover window and a reinforced cover window manufactured thereby are proposed. The method includes a first step of forming a TPI layer on a base substrate, a second step of separating the TPI layer from the base substrate, a third step of forming an adhesive buffer layer on a glass substrate, and a fourth step of stacking the TPI layer on the adhesive buffer layer. This secures the TPI's unique pencil hardness of 4H to 6H while maintaining the unique aesthetic sense and touch feeling of the glass.

A method of manufacturing a window member includes performing a first reinforcement operation including performing a first ion-exchange treatment on an initial window member. The first ion-exchange treatment includes applying ion salts at a temperature equal to or greater than a first temperature of about 500° C. A stress relief operation includes performing a heat treatment and/or a salt treatment on the initial window member to which the first reinforcement operation is performed. A second reinforcement operation includes performing a second ion-exchange treatment on the initial window member to which the stress relief operation is performed.

The subject of the invention is an induction cooking device comprising at least one inductor positioned under a thermally or chemically strengthened glass plate, the composition of the glass being of lithium aluminosilicate type.

A process for the manufacture of a heat strengthened glass substrate, includes the application of a temporary layer including a polymer on a glass substrate including a glass sheet, then the application to the glass substrate coated with the temporary layer of a treatment for the heat strengthening of the glass including heating, leading to the removal of the temporary layer, and then cooling by blowing of air through nozzles. The glass substrate thus obtained exhibits a reduced level of iridescences.

A manufacturing method of a glass substrate having holes includes irradiating a plurality of hole formation target positions of a dummy glass substrate with a laser under a first condition, to form a plurality of holes in the dummy glass substrate; heating the dummy glass substrate under a second condition; measuring, for each of the hole formation target positions, a deviation between the hole formation target position and a position of the hole after the heating formed by irradiating the hole formation target position of the dummy glass substrate; irradiating irradiation target positions of a glass substrate, having substantially same shape, dimension and composition as the dummy glass substrate, with a laser under the first condition, to form a plurality of holes, the irradiation target positions of the glass substrate with the laser being determined taking into account the deviation; and heating the glass substrate under the second condition.

A glass container comprises a glass body comprising a first region under a compressive stress extending from a surface of the glass body to a depth of compression and a second region extending from the depth of compression into a thickness of the glass body, the second region being under a tensile stress. The glass container also includes a localized compressive stress region having a localized compressive stress extending from the surface to a localized depth of compression within the body. The localized depth of compression is greater than the depth of compression of the first region. The glass container also includes a crack re-direction region extending in a predetermined propagation direction, wherein the crack re-direction region possesses a higher tensile stress than the tensile stress in the second region in a sub-region of the crack re-direction region, the sub-region extending substantially perpendicular to the predetermined propagation direction.
