2. A little history of glass
• Glass blowing is thought to have begun in Europe in the 1st-century.
However, windows made of cast glass, glass created by pouring molten
glass into a mold, have been found in important buildings in Rome and
Pompeii. Glassmaking spread through Europe and by the 17th-century
colored glass was being used in churches and cathedrals.
• During the 11th-century, the crown glass process made sheets of glass. In
this process, a glob of molten glass was put on the end of a rod. The
glassmaker then spun the rod and glass until it flattened into a disk, like
a pizza. The disk was then cooled and cut into square or rectangular
panes. This manufacturing method created a lot of optical distortions but
was used to make glass until the mid-19th century.
• Colored glass, also created by the crown glass method, was used to
create dramatic stained-glass windows during the Gothic and Baroque
periods that spanned the 11th through 18th-centuries. Once considered
a luxury only for the wealthy due to its manufacturing costs, glass began
to be used more frequently in windows of buildings.

4. Why glass in architecture ?
• Glass is a magical material which has so many different
properties and uses, that it has presented Architects with
many new possibilities and designs.
• Glass is most typically used as transparent glazing
material in construction and also used in architectural
features like doors, windows, partition.
• Glass is a transparent hard substance created by the
application of heat to sand or quartz.
• Glass is an inorganic, transparent or translucent material
which can be molded into any shape.
• Glass is a mixture of raw materials like Silica, sodium
potassium carbonate, lime or lead oxide, Manganese
oxide which is ground, sieved and mixed in specific
proportion and melted in furnace.

5. Types of glass used in architecture
• Laminated glass
• Insulating glass
• Reflective glass
• Tinted glass
• Wired glass
• Patterned glass
• Glass bricks .

6. Insulating glass
• Insulating glass:
More commonly known as double glazing, consists of
two or three glass window panes separated by a
vacuum or gas filled space to reduce heat transfer
across a part of the building envelope.
• Laminated glass :
Laminated glass is the type
of the safety glass that holds
together when shattered

7. • Reflective glass:
• Reflective glass is glass that has been treated
with a metallic coating to allow it to reflect heat.
It is not reflective in the sense that it acts as a mirror,
although some products do indeed have a highly reflective surface,
but rather in the sense that it reflects radiation
rather than absorbing it.
• Tinted glass :
• Window film is a thin laminate film that can
be installed to the interior or exterior of glass
surfaces in automobiles and boats and also to the
interior or exterior of glass in homes and buildings.
It is usually made from polyethylene terephthalate,
a thermoplastic polymer resin of the polyester family,
due to its clarity, tensile strength,
dimensional stability, and ability to accept a variety
of surface-applied or embedded treatments.

8. Advantages of glass in architecture
• The glass that absorb, refracts or transmits light. It can be
made transparent or translucent so it adds extraordinary
beauty to the building.
• It offers unobstructed views thus making the interior look big ,
when used in exteriors it helps in bringing the outdoors into
indoors .
• When used in curtains walling in the facade of interiors are
flooded with natural light though out day thus working
efficinancy .
• The external glass is treated as to reduce glare prevent heat
absorption , and resistance to UV light thus help in making
building energy efficient .

9. Disadvantages of glass
• Its is very costly material and has to be handled with care
• It requires regular cleaning in rises and maintained be can be
challenging .
• The extensive use of glass might result in both psychological
and the actual security concerns .
• As most of glass curtain walls cant be opened ventilation
needs special attention .

10. Crystal Palace
• The Crystal Palace was a cast iron and plate glass structure originally built
in Hyde park London, to house the great exhibition of 1851.
• The exhibition took place from 1 May until 15 October 1851, and more than
14,000 exhibitors from around the world gathered in its 990,000 square feet
(92,000 m2) exhibition space to display examples of technology developed
in the Industrial revolution.
• Designed by Joseph Paxton, the Great Exhibition building was 1,851 feet
(564 m) long, with an interior height of 128 feet (39 m). It was three times
the size of St Paul’s cathedral.
• The introduction of the sheet glass method into Britain by Chance Brothers
in 1832 made possible the production of large sheets of cheap but strong
glass, and its use in the Crystal Palace created a structure with the greatest
area of glass ever seen in a building. It astonished visitors with its clear
walls and ceilings that did not require interior lights.
• It has been suggested that the name of the building resulted from a piece
penned by the playwright Douglas Jerauld , who in July 1850 wrote in the
satirical magazine Punch about the forthcoming Great Exhibition, referring
to a "palace of very crystal".
• After the exhibition, the Palace was relocated to an area of South London
