An article includes a substrate with two main faces defining two main surfaces separated by edges, the substrate carrying a functional coating deposited over at least a portion of a main surface and a temporary protective layer deposited over at least a portion of the coating. The temporary protective layer has a thickness of at least 1 micrometer. The temporary protective layer made of polyfuran resin is obtained from a liquid composition comprising furfuryl alcohol.

A shaped glass article is provided that is ultrathin, has two surfaces and one or more edges joining the two surfaces, and a thickness between the two surfaces. The shaped ultrathin glass article has at least one curved area with a non-vanishing surface curvature with a minimal curvature radius R if no external forces are applied. A method for producing a shaped glass article is also provided that includes providing an ultrathin glass with two surfaces and one or more edges joining the two surfaces, having a thickness between the two surfaces and shaping the ultrathin glass to a shaped ultrathin glass article by forming at least one curved area having a non-vanishing surface curvature with a minimal curvature radius R if no external forces are applied to the shaped ultrathin glass article.

A glass sheet is a single glass sheet having a first surface and a second surface facing the first surface. The glass sheet has a curvature part curved in a first direction and a second direction orthogonal to the first direction. A radius of curvature in the first direction of the curvature part is 8,500 mm or less. At least a part of the first surface has been chemically strengthened in the curvature part. In the first direction within the chemically strengthened region in the curvature part, an Na amount in the first surface is smaller than the Na amount in the second surface.

To suppress reduction in rigidity. A cover material has a curvature in a first direction X and a curvature in a second direction Y. The curvature in the first direction X and the curvature in the second direction Y intersect with each other on a plane of the cover material 10. The radius of curvature of the curvature in the first direction X is 60 mm or more and 300 mm or less. The radius of curvature of the curvature in the second direction Y is 1000 mm or more and 14000 mm or less.

A bendable glass and substrate assembly including a glass panel that has a planar pre-installation geometry and first and second panel surfaces that are separated by a panel thickness and at least one substrate that is bonded to at least a portion of the first panel surface. Both the glass panel and the substrate are made of bendable materials and are adapted to take on at least one bent post-installation geometry that is different than the planar pre-installation geometry. The bendable materials of the glass panel and the substrate remain flexible and resilient even after the substrate is bonded to the glass panel and as a result the bendable glass and substrate assembly has a planar geometry before installation and is bent to a final non-planar shape or contour when the bendable glass and substrate assembly is mounted in a final installation.

A process for manufacturing a bent laminated glazing, includes manufacturing a first bent laminated glazing including at least two glass substrates locally comprising, in each of the at least two glass substrates and facing each other in all the at least two glass substrates, a zone including compressive stresses, and cutting the first bent laminated glazing through its entire thickness along a line included in the zone in order to form local cut edges and, after cutting, a second bent laminated glazing with the local cut edges having compressive edge stresses.
