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.

“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)
“For it is with the mysteries of our religion, as with wholesome pills for the sick, which swallowed whole, have the virtue to cure; but chewed, are for the most part cast up again without effect.”
—Thomas Hobbes (1588–1679)
“Our press is certainly bankrupt in the “thrill of awe”Motherwise reverence: reverence for nickel plate and brummagem. Let us sincerely hope that this fact will remain a fact forever; for to my mind a discriminating irreverence is the creator and protector of human liberty.”
—Mark Twain [Samuel Langhorne Clemens] (1835–1910)
“the loose fragrant cavendish
and the shag,
And the bright Virginia
loose under the bright glass cases,”
—Ezra Pound (1885–1972)
