What was the process of making plate glass? - Answers--
Molten glass was cut into frames, spread into sheets by
rollers, cooled, then ground flat and polished with
abrasives, first on one side and then on the other.
-Result was a costly glass of near-perfect optical quality in
sheets of unprecedentedly large size.
What made plate glass affordable in the 19th century? -
Answers--Mechanization of grinding and polishing
operations in 19th century reduced price of plate glass to
level that allowed it to be used for storefronts in Europe
and U.S
When was float glass first produced? By who? - Answers-
in 1959 by an English firm of Pilkington Brothers Ltd.
What process of glass making do we use today? -
Answers-float glass- it replaced both drawn glass and
plate glass

What is the process of making float glass? - Answers--
Ribbon of molten glass is floated across a bath of molten
tin, where it hardens before touching a solid surface.
-Ordinary window glass is annealed, meaning it is cooled
slowly under controlled conditions to avoid locked-in
thermal stresses.
-Resulting sheets of glass have parallel surfaces, high
optical quality (virtually indistinguishable from that of plate
glass), and brilliant surface finish.
-Has been produced in U.S. since 1963 and now accounts
for nearly all of domestic flat glass production
glazing - Answers-refers to the installing of glass in an
opening or to the transparent material (usually glass) in a
glazed opening
glazier - Answers-installer of glass
lights/lites - Answers-individual pieces of glass
What makes up glass? - Answers-Sand! (silicon dioxide)
, 3|Page
Sand is mixed with soda ash, lime, and small amounts of
alumina, potassium oxide, and various elements to control
color, then heated to form glass.
Finished material while seemingly crystalline and
convincingly solid is, is actually a supercooled liquid or
amorphous solid. It has no melting point and an open,
noncrystaline microstructure
When was crown glass and cylinder glass produced? -
Answers-By 10th century A.D., Venetian island of Murano
had become the major center of glassmaking, producing
crown glass and cylinder glass for windows.
How is process of making crown glass and cylinder glass
the same? - Answers-Both processes began by blowing a
large glass sphere (drawn glass).
How was crown glass produced? - Answers--Heated glass
sphere was adhered to an iron rod opposite the blowpipe.
-Sphere was reheated and glassworker spun the rod
rapidly, causing centrifugal force to open the sphere into a
large disk, or crown, 30 inches or more in diameter.
-When crown was cut into panes, one pane always
contained the "bullseye."
