Bent Glass
Bent glass , i.e. curved glass is extensively used by the auto industry for making windshields and by architects for creating glass domes, display cases, and revolving doors.
When float glass comes off the manufacturing line it is a flat sheet. Later the glass can be made to bend when the need or design calls for it. Due to the brittleness of glass, bending must happen while the glass is still warm enough to be manipulated but not so hot that it is molten.
- To bend the glass, we place a piece of glass over a piece of metal made to simulate the curve needed for the glass. Both the metal and glass are placed into an oven and heated until the glass begins to soften, at which point both the glass and the metal form are removed from the heat.
- Bent glass is strong and shock-resistant as annealed glass is heated to 700°C and is cooled rapidly to induce glass strength. This type of glass is used in staircases, cabins, and other interiors
