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, which pioneered the technique (invented by Sir Alastair Pilkington) in the 1950s.

Famous quotes containing the words float and/or glass:
“For all this sea-hoard of deciduous things,
Strange woods half sodden, and new brighter stuff:
In the slow float of differing light and deep,
No! there is nothing! In the whole and all,
Nothing that’s quite your own.
Yet this is you.”
—Ezra Pound (1885–1972)
“Thou didst create the night, but I made the lamp.
Thou didst create clay, but I made the cup.
Thou didst create the deserts, mountains and forests,
I produced the orchards, gardens and groves.
It is I who made the glass out of stone,
And it is I who turn a poison into an antidote.”
—Muhammad, Sir Iqbal (1873–1938)
