Creation of glazing comprising an opening

A method for preparing a sheet of curved glass comprising an opening, the method comprising bending the sheet of glass followed by cooling,

• wherein
• a periphery of the sheet of glass and a periphery of the opening therein are supported, at least at the start of the cooling, by a final skeleton,
• a perimeter of the opening has, at all points, a radius of curvature of at least 60 mm,
• the final skeleton comprises a continuous linear strip of metal having an edge face facing upward to support the sheet of glass,
• a thickness of the edge face ranges from 1 to 5 mm,
• the bending is performed at least partially under gravity on a bending skeleton supporting the periphery of the sheet of glass and the periphery of the opening,
• a concavity of a part of the bending skeleton that supports the periphery of the opening increases during the bending,
• the part of the bending skeleton that supports the periphery of the opening comprises two skeletons which support the opening, one after the other, during the bending,
• a part of the bending skeleton that supports the periphery of the sheet of glass comprises two skeletons which support the sheet of glass, one after the other, during the bending, and a second skeleton that supports the sheet of glass after a first skeleton has a more pronounced curvature than the first skeleton,
• wherein the final skeleton lies a distance away from an edge of the opening of at least 2 mm at least at the start of the cooling and wherein the tangent of the support does not cross into said support along the border of the support of the opening.
