Rolled glass

4. • Plate glass made by allowing it to solidify on a
layer of molten metal
• It the most common glass used in the
construction industry
• They have a uniform thickness and are very flat
• The float glass process is also known as the
Pilkington process, named after the British glass
manufacturer Pilkington, which pioneered the
technique
Float glass

5. Float glass uses common glass-making raw materials, typically consisting
of sand, soda ash (sodium carbonate), dolomite, limestone, and salt cake
(sodium sulfate)
They are classified into five broad categories based on the market
demand
• Clear float glass
• Tinted float glass
• Reflective float glass
• Frosted float glass
• Ultra clear float glass
• Mirror glass
• Lacquered glass

6. Clear Float Glass
Its the basic glass made and all other glasses are just add-ons to the clear
float glass

7. Tinted float glass
This term refers to any glass that has been treated with a material such as a
film or coating that reduces the transmission of light through it. Glass can be
tinted with various types of coating, which block and/or reflect different
amounts and types of light, according to the needs and preferences of the
consumer.

8. Reflective Glass
Window glass which has been coated on the outside with a transparent
metallic coating to reflect a significant fraction of the light and radiant heat
which strikes it.

Low emissivity and good solar control.
Reflective properties help eliminate
interior reflection for a perfect look
and more design flexibility.

9. Frosted glass
Frosted glass is produced by the sandblasting or acid etching of clear sheet
glass. It has the effect of rendering the glass translucent by scattering of light
during transmission, thus blurring images while still transmitting light.
• To obtain visual privacy while admitting
light.
• Decorative patterns may be imposed upon
otherwise plain glass by using wax or other
resist to retain transparent areas.
• Frosted glass in light bulbs is used for evenly
distributing the light from the bulb's
filament across its surface area.

10. Acid and Sand Frosted glass

Quality
Comparison
Acid frosted glass are higher in price
and quality because of it properties
• Better texture
• Oil stain resistant
• Variety and choice of design
available
Price
1 sq.ft 5mm acid frosted with design glass slab - ₹100
1 sq.ft 5mm acid frosted glass slab - ₹75
1 sq.ft 5mm sand frosted glass slab - ₹50- ₹55
The price difference is mainly because acid frosted glasses are imported (from places
like china)

11. Ultra clear glass
Low iron glass is ultra clear and provides a higher degree of
transparency than clear float glass. This optimum clarity is
achieved by removing most of the iron oxide content used to
produce glass. The improved clarity of low iron glass compared
with clear float glass is barely discernable unless the two types
of glass are viewed against a coloured background

• Substantially reduced green
tinge
• This eliminates colour
distortion apparent in clear
float glass.
• Enhanced external viewing
• Gives glass the highest
degree of visible light
transmission.

13. Lacquered glass
Colored and opaque in appearance, produced by depositing and then baking
a coating of lacquer to one side.
• With colour and light effects,
lacquered glass helps convey a bright
and creative appearance for walls
and furniture.
• As the lacquer is applied to the back
of the glass, it is protected from
damage, ensuring durability.
• This variety of glass can be used in
high humidity rooms, such as
kitchens and bathrooms.

14. Mirror Glass
Mirrors are manufactured by applying a reflective coating to a suitable substrate.
The most common substrate is glass, due to its transparency, ease of fabrication,
rigidity, hardness, and ability to take a smooth finish. The reflective coating is
typically applied to the back surface of the glass, so that the reflecting side of the
coating is protected from corrosion and accidental damage by the glass on one
side and the coating itself and optional paint for further protection on the other.
Types of mirror
• Plane mirror
• Concave mirror
• Convex mirror
Types of glass
• Aluminium glass mirror
• Low aluminium glass mirror
• Safety glass mirror
• Silk glass mirror
• Silver glass mirror

16. Toughened Glass
Toughened or tempered glass is a type of safety glass processed by
controlled thermal or chemical treatments to increase its strength
compared with normal glass. Tempering puts the outer surfaces into
compression and the inner surfaces into tension.

17. Production
Glasses are chosen Cut Holes are
drilled Passed through a furnace of about
650⁰c slow cooling
• Slow cooling is the reason for the toughness
• Slow cooling increases the strength to about
20%
• Toughened glass cannot be altered
• This is also the reason for the high cost

• Used in automobile
wind shield
• Used in hotels, sound
proof rooms,
recording theatres etc
• Similarly many such materials can be added to make different kinds of tempered
glass
• Any glass can be toughened except for lacquered glass
• The price differs according to the glass which is toughened and the material used
inside
• Toughened glass breaks into sugar like particle and hence not harmful

21.  One of the important aspect for glass retailing is ware- housing
 Manufacturing companies stop with the manufacture of the glass
 Glasses are manufactured in standard size and dimensions
 It is in the wear house the glass undergo process like
 An investment of 500cr INR is needed to setup a glass manufacturing
company
 And an investment of 5cr INR is needed to setup a toughened glass
manufacturing company

23. Reasons contributing for price variation
• As the value additions increase the price also increases
• The variation in price is also influenced from where it is
imported
• Usually as the demand increase the price also increase
• Other factors like thickness and size of the glass influence
the price
• Promotion and establishment of a brand/company also
influence the price(Marginal variation in price)

24. Glass blocks
Glass brick, also known as glass block, is an
architectural element made from glass. Glass bricks
provide visual obscuration while admitting light.
