Flat glass, sheet glass, or plate glass is a type of glass, initially produced in plane form, commonly used for windows, glass doors, transparent walls, and windshields. For modern architectural and automotive applications, the flat glass is sometimes bent after production of the plane sheet. Flat glass stands in contrast to container glass (used for bottles, jars, cups) and fiberglass (used for thermal insulation and optical communication). Most flat glass is soda-lime glass, produced by the float glass process. Other processes for making flat glass include:
- Rolling (Rolled plate glass, Figure rolled glass)
- Overflow downdraw method
- Blown plate method
- Broad sheet method
- Window crown glass technique
- Cylinder blown sheet method
- Fourcault procvaginaess
- Machine drawn cylinder sheet method
- Plate polishing
Famous quotes containing the words flat and/or glass:
“It would astonish if not amuse, the older citizens of your County who twelve years ago knew me a stranger, friendless, uneducated, penniless boy, working on a flat boat—at ten dollars per month to learn that I have been put down here as the candidate of pride, wealth, and aristocratic family distinction.”
—Abraham Lincoln (1809–1865)
“I must sojourn once to the ballot-box before I die. I hear the ballot-box is a beautiful glass globe, so you can see all the votes as they go in. Now, the first time I vote I’ll see if the woman’s vote looks any different from the rest—if it makes any stir or commotion. If it don’t inside, it need not outside.”
—Sojourner Truth (c. 1797–1883)
