A method for adhering embellishments to a glass substrate. The method provides a depression in the glass matching the shape of the embellishment, allowing for a lower profile and protecting the adhesive from water and solvents, thus reducing the chance of the embellishment falling off of the glass.

Embodiments of a article including include a substrate and a patterned coating are provided.

A method of forming a sensor, such as a glass electrochemical sensor, is described. In some examples, the method may include forming a plurality of apertures in a glass substrate; forming a sensor body comprising the glass substrate and at least one glass sensor component, wherein one or more apertures of the glass substrate are aligned with the at least one glass sensor component to form an outer contact aperture; filling the outer contact aperture in the sensor body with a first conducting material to form an outer contact through glass via (TGV); and forming an electrode on the glass substrate adjacent at least one of the apertures of the plurality of apertures.

An antiglare glass substrate includes a glass substrate having a first main surface and a second main surface that is opposite to the first main surface. The first main surface has undergone an antiglare treatment and a fluorine-containing organosilicon compound coating film as an antifouling film is laminated thereon. The first main surface partly includes a non-antiglare-treated portion that has not undergone the antiglare treatment. The non-antiglare-treated portion has a surface roughness Ra of less than 10 nm. A difference in height along a plate thickness direction of the glass substrate between the antiglare-treated portion that has undergone the antiglare treatment and the non-antiglare-treated portion is 10

A method of manufacturing a flexible cover window is proposed. The flexible cover window includes a planar part and a folded part extending continuously from the planar part, wherein the folded part is thinner than the planar part. The method includes: forming a photoresist layer on a glass substrate, patterning the photoresist layer to form a gradation resist pattern layer for forming the folded part on the glass substrate, forming the folded part having an inclined portion formed between the folded part and the planar part using the gradation resist pattern layer as a mask, removing the gradation resist pattern layer, and reinforcing the glass substrate.
