Cast Plate Glass
Developed by James Hartley, 1848. The glass is taken from the furnace in large iron ladles, which are carried upon slings running on overhead rails; from the ladle the glass is thrown upon the cast-iron bed of a rolling-table; and is rolled into sheet by an iron roller, the process being similar to that employed in making plate-glass, but on a smaller scale. The sheet thus rolled is roughly trimmed while hot and soft, so as to remove those portions of glass which have been spoiled by immediate contact with the ladle, and the sheet, still soft, is pushed into the open mouth of an annealing tunnel or temperature-controlled oven called a lehr, down which it is carried by a system of rollers.

Famous quotes containing the words plate glass, cast, plate and/or glass:
“I sometimes have the sense that I live my life as a writer with my nose pressed against the wide, shiny plate glass window of the “mainstream” culture. The world seems full of straight, large-circulation, slick periodicals which wouldn’t think of reviewing my book and bookstores which will never order it.”
—Jan Clausen (b. 1943)
“When such as I cast out remorse
So great a sweetness flows into the breast
We must laugh and we must sing,
We are blest by everything,
Everything we look upon is blest.”
—William Butler Yeats (1865–1939)
“Then he rang the bell and ordered a ham sandwich. When the maid placed the plate on the table, he deliberately looked away but as soon as the door had shut, he grabbed the sandwich with both hands, immediately soiled his fingers and chin with the hanging margin of fat and, grunting greedily, began to much.”
—Vladimir Nabokov (1899–1977)
“More Safe, and much more modest ‘tis, to say
God wou’d not leave Mankind without a way:
And that the Scriptures, though not every where
Free from Corruption, or intire, or clear,
Are uncorrupt, sufficient, clear, intire,
In all things which our needfull Faith require.
If others in the same Glass better see
‘Tis for Themselves they look, but not for me:
For MY Salvation must its Doom receive
Not from what OTHERS, but what I believe.”
—John Dryden (1631–1700)
