A process for preparing a laminated glazing involves providing a first glass sheet having a desired shape with a first thickness, providing a second glass sheet having a desired shape with a second thickness; providing an interlayer between the first and second glass sheet; applying a mould shaped substantially the same as the first glass sheet against the second glass sheet; aligning the two glass sheets and misaligning the mould with respect to the two glass sheets so the mould is offset relative to the two glass sheets; and laminating together the first and second glass sheets and the interlayer at a temperature and pressure sufficient to adhere the interlayer to the glass sheets, such that after lamination, the second glass sheet is offset relative to the first glass sheet whilst the shape of the second glass sheet is substantially the same as the shape of the first glass sheet.

A process for manufacturing a laminated glazing that includes at least a first glass sheet and a second glass sheet, includes printing a face of the first glass sheet intended to be oriented toward the second glass sheet with a liquid enamel which is dried at a temperature not exceeding 400° C., then bending the first and second glass sheets together in contact with one another in their relative position of destination in the laminated glazing, by heating at a softening temperature of the glass, wherein the liquid enamel is an aqueous silicate paint including a refractory powder of pigments and a silicate binder powder, in the absence of glass frit, and wherein a weight ratio of pigments to silicates is greater than 1.

A device and a process for the gravity bending of a glass sheet or a stack of glass sheets, referred to as the glass, includes the gravity bending of the glass on a skeleton including a contact rail supporting the glass in the peripheral zone of the lower main face thereof, the contact rail including concave curvatures in each of the sides of the skeleton, a counter-skeleton including a metal bar being present during the bending at a distance d from the edge face or from the peripheral zone of the upper main face of the glass, the peripheral zone of a main face being the zone between the edge of the glass and a distance from the edge of the glass of 50 mm of the main face, d being within the range from 0.1 to 50 mm.

Embodiments of a method for pair bending glass articles is provided herein. In the method, a first glass article and a second glass article are stacked to form a stack. The first glass article includes a first surface, a second surface that opposes the first surface, and a first composition having first annealing and softening temperatures. The second glass article includes a third surface, a fourth surface that opposes the third surface, and a second composition having second annealing and softening temperatures. The annealing temperatures are within 35° C. of each other and are at least 550° C. The softening temperatures are within 35° C. of each other and are at least 750° C. In the method, the stack is placed on a mold, and the stack is heated to a sagging temperature such that a shaped stack is formed.

A manufacturing method for a laminated glass in which a plurality of glass plates are laminated, includes a first main forming step of heating a first glass plate to a first softening point or higher to perform a main forming; a second main forming step of heating a second glass plate to a second softening point or higher to perform the main forming; a first finish forming step of bending and forming the first glass plate into a desired shape; and a second finish forming step of bending and forming the second glass plate into a desired shape. The first and second main forming steps are performed by using a same forming die. A first condition for lowering a temperature of the first glass plate to below the first softening point and a second condition for the second glass plate are different from each other.

Embodiments of the disclosure relate to a method of preparing a multi-piece laminated article. In the method a first glass ply and a second glass ply are co-sagged. The first glass ply is laser cut to form a first primary piece and a first secondary piece, and the second glass ply is laser cut to form a second primary piece and a second secondary piece. The first primary piece and the second primary piece each define a hole into which the first secondary piece and the second secondary piece, respectively, fit. The first primary piece and the second primary piece are laminated to each other to form a first laminated piece, and the first secondary piece and the second secondary piece are laminated to each other to form a second laminated piece. The method can be used to prepare, for example, automotive glazing.
