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:
“Out in Hollywood, where the streets are paved with Goldwyn, the word “sophisticate” means, very simply, “obscene.” A sophisticated story is a dirty story. Some of that meaning was wafted eastward and got itself mixed up into the present definition. So that a “sophisticate” means: one who dwells in a tower made of a DuPont substitute for ivory and holds a glass of flat champagne in one hand and an album of dirty post cards in the other.”
—Dorothy Parker (1893–1967)
“Lay down, lay down the bigly bier,
Lat me the dead look on;
Wi’ cherry cheeks and ruby lips
She lay an’ smil’d on him.
O ae sheave o’ your bread, true-love,
An’ ae glass o’ your wine,
For I hae fasted for your sake
These fully day [is] nine.”
—Anna Gordon Brown (1747–1810)
