Glass can be produced through float glass processes or glassblowing. Float glass involves floating molten glass on molten tin to produce uniform, flat sheets for modern windows. Glassblowing makes bottles and containers. There are several types of glass like float glass, laminated safety glass, stained glass, tinted glass, and toughened glass. Glass has advantages like various sizes, colors, and being waterproof and rustproof but has disadvantages as it breaks easily and melts at high temperatures. Glass has many applications in buildings as windows, walls, and interior uses due to its light transmission properties.

3. GLASS PRODUCTION
Glass production involves 2 main methods:
•the float glass process which produces sheet glass
• Glassblowing which produces bottles and other
containers.
 GLASS CONTAINER FACTORIES :-
 Modern glass container factories are 3 part operations:
- the batch house, the hot end, and the cold end
• The batch house handles the raw materials
• The hot end handles the manufacture proper — the
furnaces, annealing ovens, and forming machines
•The cold end handles the product-inspection and
packaging equipment.

4. GLASS COMPONENTS
Glass is an amorphous (non-
crystalline) solid material which is
often transparent and has
widespread practical,
technological, and decorative
usage in things like window
panes, tableware, and
optoelectronics.
 The most familiar, and
historically the oldest, types of
glass are based on the chemical
compound silica (silicon
dioxide), the primary constituent
of sand.

5. ADVANTAGES & DIS-ADVANTAGES OF
GLASS
 Advantages :-
-Can be made in different sizes
-Can be coloured or colourless
-Does not rust
-Waterproof
 Disadvantages :-
-An expensive material
 -Breaks easily-Melts in high temperatures
-When broken, the pieces may be sharp

6. Types Of glass
 Float glass
Is Made up of floating molten glass
on a bed of molten tin.
This method gives the sheet
uniform thickness and very flat
surfaces.Modern windows are mde
from float glass.

7. Types Of Glass
 Laminated Glass
Type of safety glass that holds
together when shattered
Held in place by interlayer,
typically of polyvinyl betrayal,
between its two or more layers of
glass
Interlayer keeps it bonded when
broken.
Produces spider web pattern
when broken.

8. Types Of Glass
 Stained Glass
The term explains a glass
generally refers to glass that has
been coloured by adding
metallic salts during the
manufacture.
The coloured glass is crafted
into stained glass windows in
which small pieces of glass are
arranged to form patterns or
pictures, held together by strips
of lead and supported by a rigid
frame.

9. Types Of Glass
 Tinted Glass
There are many varieties into this type like tinted float glass,
including colors of dark blue, French green, dark green, dark
grey, bronze and pink.

10. Types Of Glass
 Figured Glass
They are of two types.
1) Clear
2) Colored
The patterns are of flora,
kasumi, mistlite, Pin Head,
Reeded, Yozura, Konoha,
Karatachi etc,

11. Types Of glass
 Beveled Glass
Usually made by taking one
quarter inch thick clear glass
and creating a one inch
bevel on one side around
the entire periphery.
This bevels act like prisms in
sunlight creating interesting
color diffraction which both
highlights the glasswork and
provides a spectrum of
colors which are usually
absent in float glass.
These can vary from simple
three or four piece designs.

12. Types Of Glass
 Toughened Glass

13. Types Of Glass
 Insulated Glass
Consists Of two or more
lites of glass separated by
a hermitically sealed
space for thermal
insulation and
condensation control.
Used Specially for
windows, curtain walls and
skylights.

14. Types Of Glass
 Wired Glass
Involves steel wires rolled
into sheets of glass.
A wire mesh is inserted
during the manufacturing
of plate glass, allowing the
glass to adhere together
when cracked.
Can Be qualified as safety
glass for some
applications.
