The present invention provides crystallized glass of three-dimensional shape for easily producing chemically strengthened glass of three-dimensional shape that resists damage and has exceptional transparency. This crystallized glass of three-dimensional shape: contains crystals; has light transmittance in terms of a thickness of 0.8 mm of 80% or higher; and contains 45-74% SiO.sub.2, 1-30% Al.sub.2O.sub.3, 1-25% Li.sub.2O, 0-10% Na.sub.2O, 0-5% K.sub.2O, a total of 0-15% of SnO.sub.2 and/or ZrO.sub.2, and 0-12% P.sub.2O.sub.5, these amounts expressing the oxide-based mass percentage.

The present disclosure relates to a method of manufacturing a curved joined glass sheet having excellent optical quality by adjusting a radius of curvature of a curved thick glass sheet and a radius of curvature of a curved thin glass sheet. The method includes preparing a curved thick glass sheet having a first radius of curvature, manufacturing a curved thin glass sheet having a second radius of curvature by heating and molding a flat plate thin glass sheet, providing a joining film or an adhesive agent between a concave surface of the curved thick glass sheet and a convex surface of the curved thin glass sheet, and elastically deforming the curved thin glass sheet to join the elastically deformed curved thin glass sheet so as to match with the concave surface of the curved thick glass sheet

A table can be made entirely from tempered glass. Structural components including the table top, end pieces, and a stabilizing cross piece can be made from glass. Glass connectors can be used to attach the structural components. The structural components of the table can be shaped to provide shapes that can become an integral part of the design. Rubber feet can be used to protect the glass and floors. The glass can be printed using a high temperature printing process to provide visual appeal to the overall design. The table can be particularly suited to outdoor use due to its durability and ease of cleaning. The table can also incorporate bent tempered glass to provide strength and alternative design options.

An edge-press molding element is part of a glass-bending tooling that includes a contoured-ring, gasket form factor. The edge-press molding element operates by self-weight bending a glass pane under a thermal load. The glass pane bends under molding conditions where a temperature differential of as low as 30 C. up to 100 C. is achieved between an edge of the glass pane and the center.

A system and process for forming a curved glass laminate article is provided. The process and system utilizes co-sagging of a stack of glass sheets of different thicknesses and different glass materials. During co-sagging the thicker glass layer is placed on top of the thinner glass layer. In this process, shape mismatch is avoided by selecting/controlling the glass materials of the sheets of glass such that the viscosity of the lower, thinner sheet during co-sagging is greater than the viscosity of the thicker glass sheet.

Disclosed herein are glass forming furnaces and methods of using the same. The glass forming furnaces may include a housing and a bending ring. The housing may define a chamber. The bending ring may include a first inlet port, a first outlet port, and a channel. The bending ring may be located within the chamber. The channel may have a shape that is similar to a shape of a glass article. The channel may define a cavity fluidly connecting the first inlet port and the first outlet port.

Various embodiments disclosed relate to an assembly for bending glass. The assembly includes a support extending along an x-direction and a y-direction. The support includes a support first major surface and opposed second major surface. The assembly further includes a bending ring attached to and extending vertically along a z-direction from the support first major surface substantially along an outer perimeter of the support first major surface. The assembly further includes a passive heat element disposed between the support first major surface and a top end of the bending ring.

A process and system for forming a curved glass article from a sheet of glass material is provided. The process and system includes supporting a glass sheet on a shaping frame and then heating the sheet of glass material while supported by the shaping frame such that the central region of the sheet of glass material deforms into an open central cavity of the bending frame. The process and/or system are configured such that a steep, localized temperature differential is formed in the region adjacent the outer edge of the glass sheet during the heating stage of the shaping process.

Embodiments of a laminate including a first curved glass substrate comprising a first viscosity (poises) at a temperature of 630 C.; a second curved glass substrate comprising a second viscosity that is greater than the first viscosity at a temperature of 630 C.; and an interlayer disposed between the first curved glass substrate and the second curved glass substrate, are disclosed. In one or more embodiments, the first curved glass substrate exhibits a first sag depth that is within 10% of a second sag depth of the second curved glass substrate. In one or more embodiments, the first glass substrate and the second glass substrate exhibit a shape deviation therebetween of about 5 mm or less as measured by an optical three-dimensional scanner or exhibit minimal optical distortion. Embodiments of vehicles including such laminates and methods for making such laminates are also disclosed.
