Float Glass Process
Float glass is a sheet of glass made by floating molten glass on a bed of molten metal, typically tin, although lead and various low melting point alloys were used in the past. This method gives the sheet uniform thickness and very flat surfaces. Modern windows are made from float glass. Most float glass is soda-lime glass, but relatively minor quantities of specialty borosilicate and flat panel display glass are also produced using the float glass process. The float glass process is also known as the Pilkington process, named after the British glass manufacturer Pilkington, who pioneered the technique (invented by Sir Alastair Pilkington) in the 1950s.

Famous quotes containing the words float, glass and/or process:
“Over the tree-tops I float thee a song,
Over the rising and sinking waves, over the myriad fields and the
prairies wide,
Over the dense-packed cities all and the teeming wharves and ways,
I float this carol with joy, with joy to thee, O death,”
—Walt Whitman (1819–1892)
“Nor do I try to keep a garden, only
An avocado in a glass of water—”
—James Merrill (b. 1926)
“I’m not suggesting that all men are beautiful, vulnerable boys, but we all started out that way. What happened to us? How did we become monsters of feminist nightmares? The answer, of course, is that we underwent a careful and deliberate process of gender training, sometimes brutal, always dehumanizing, cutting away large chunks of ourselves. Little girls went through something similarly crippling. If the gender training was successful, we each ended up being half a person.”
—Frank Pittman (20th century)
