Book Formatting: Quality Control Checks for DesignersConfidence Ago
This presentation was made to help designers who work in publishing houses or format books for printing ensure quality.
Quality control is vital to every industry. This is why every department in a company need create a method they use in ensuring quality. This, perhaps, will not only improve the quality of products and bring errors to the barest minimum, but take it to a near perfect finish.
It is beyond a moot point that a good book will somewhat be judged by its cover, but the content of the book remains king. No matter how beautiful the cover, if the quality of writing or presentation is off, that will be a reason for readers not to come back to the book or recommend it.
So, this presentation points designers to some important things that may be missed by an editor that they could eventually discover and call the attention of the editor.
2. DEFINITION
• The term Glass signifies an amorphous solid substance
that has been formed by super cooling; a liquid solution
containing chiefly silica and some other selected
components.
• In General usage glasses are defined as super cooled
liquid.
3. MANUFACTURING
• The basic raw material for the manufacturing of good
quality glass is silica, which in nature occurs as quartz (
SiO2 ), the material melts at 1700 0C and is cooled rapidly
without allowing It to undergo recrystallization.
• Quartz and other desired components are heated in
special melting furnace. The molten glass comes out,
rather flows, from these furnaces continuously. Various
Glass shapes are obtained from this molten glass by one
of the following process.
4.
5. PRESSING
BLOWING
DRAWING
Air is blown in a controlled manner
through the molten glass in proper
containers. This air pressure drags the
glass liquid to a desired shape.
Moulds of the required shapes are filled
with the molten glass. It is then cooled
while under desired pressure. Sheets of
glass are made by this method.
In this process, stream of molten glass
is made to pass through the molten
rolls. It comes out from the other side
in the desired drawn from on cooling.
MANUFACTURING PROCESS
6.
7. PROPERTIES
• Glass has quite high tensile strength. In very fine wires drawn from melts glass
may show tensile strength as high as 7.0 x 10 5 kg/ cm2 .
•The ordinary glass thread possess tensile strength of 700 to 1400 kg/ cm2
• The modulus of elasticity of glass is also very high. Both these properties .
However show great variation depending upon the composition of the glass and
method of manufacturing.
• Glasses have low ductility, low conductivity and low coefficient of thermal
expansion.
• Glasses are resistant to acids and many other chemicals hence they are ideal
material for storage of chemicals.
• Glasses are very good electrical Insulators
•They have very high softening point and can be used at high temperature.
8. Many varieties of glass are made by adding special compounds in
the silicon dioxide at the time of fusion. Following are some
commonly used types of commercial Glass
Silica Glass
• It is pure Silica SiO2 , without any additives. Its use is restricted to
high temperature applications. It has a high softening
temperature.
Soda Lime Glass
• This is the most common type of glass used extensively for
domestic purpose; window panes, plate Glass, Light Bulb, and
Containers. It is composed of SiO2 , Na2O, CaO.
TYPES OF GLASS
9. Leaded Glass
This glass has a high reflective Index. This property is Induced into the
Glass by adding lead Oxide with Silica during the manufacturing Stage. A
usual Composition of lead glass is SiO2 , PbO, K2O, Na2O.
This Lead glass has special application such as;
• In Making shields for protection against gamma radiations.
• In the manufacturing of optical Instruments • For Making Neon Signs.
TYPES OF GLASS
10. Borosilicate Glass ( Pyrex)
• It is special type of glass made by adding Boron Oxide as the chief additive
with Silica at the time of Manufacturing. This property of boron oxide gives the
special property of increasing its melting point and resistance against thermal
shock. This Glass can be heated or cooled again & again without any risk of
damage. This is because the coefficient of expansion gets reduced considerably
by the addition of boron Oxide
• Borosilicate Glass is used extensively in high temperature conditions such as;
• Making of Laboratory wares for experiments;
• Cooking Utensils
• It is also used for telescope and Glass piping.
• Pyrex is the trade name for Borosilicate.
TYPES OF GLASS
11. Glass used in industry in variety of forms, some common forms
are as follows;
Pressed Glass
• This is prepared by molding the fused glass into sheets and other
shapes under pressure. These sheets are starting material for
making Glasswares and Structural Blocks.
Glass Building Blocks
• These are manufactured from pressed glass by fusing two or
more sheets in such a way that partial vacuum is caused in the
interior of the blocks. These blocks are used in masonry
construction for permitting transmission of Light without being
transparent and without bearing any load.
INDUSTRIAL FORMS OF GLASS
12. INDUSTRIAL FORMS OF GLASS
Glass Fibres
• It has been found that very thin fibres of Glass possess very high
tensile strength. The thinner the fibre the higher the strength. This
property has resulted in a separate industry of considerable
importance the glass fibre industry fibre of glass are made in a
special manner the molten glass is forced out through numerous
minute openings in the form of thin streams upon these stream is
impinged a blast of air or stream under a pre-calculated pressure.
The stream solidifies into thin fibres. The Glass-reinforced plastic is
commonly known as FIBRE GLASS and has acquired a place of its
own as a composite engineering Material.
13. LaminatedGlass
• These are made by bounding together two or more plates of
glass. Sometimes, layer of a third material like asphalt, rubber or
resin are also made a part of the laminated glass.
Laminated Glass can be characterized as :
• Shattering Resistance
• Its pieces do not fly away in all the direction on it broken
suddenly under impact. This makes the laminated Glass an ideal
material for use as a safety glass in automobile and air craft.
• Shock Resistance
• It can bear safely sudden impacts up to desired value. This
property also plays in laminated glass being Used as a safety
Glass.
INDUSTRIAL FORMS OF GLASS
14. INDUSTRIAL FORMS OF GLASS
Bullet Resistant Glass
• This is specially useful in vehicles and other
automobiles used for security reasons. It is in fact a
variety of laminated glass which is made by pressing to-
geather several layers of glass and vinyl resins in
alternate manner. Thickness of such Glass varies from
12 mm to 75 mm or more.
15. USES OF GLASS
Glass has a very wide field of Industrial Applications;
For an Architect;
• Glass is an indispensible architectural material. In
all the modern building including the high-rise
buildings, Glass curtain walls make the skyline.
16. USES OF GLASS
For an Civil Engineer;
• It is one of the most important material for
construction which cannot be avoided.
For An Electrical Engineer;
• Glass is a useful insulating material in many
situations, and is also an essential material for
making tubes and valves.
17. USES OF GLASS
For a Mechanical Engineer;
• Glass alone or in a composite material is an integral part in
automobiles and other locomotives including railway wagons
To a Chemical Engineer;
• It is packaging material without any easy alternative.
• Glass finds its application from the kitchen of poor man to
most advanced scientific devices and in palatial building and
Cabinet Rooms. It can be made in varieties possessing a
combination of mechanical, electrical, optical, and chemical
resistant properties that make them ideal industrial Material
for variety ofApplications.
