Glass formation stages
Glass is one
of the famous materials used in many different applications in life, such as
windows, antiques, etc.
There are
many different types of glass,
but the most
common is that used in the manufacture of windows Consists of more than
three-quarters of silica.
For many
thousands of years, many of the historical manuscripts have shown the presence
of glassware,
which was
used by humans more than 2,000 years ago, from household glassware, decorative
pieces, ornamental pieces,
and then
their use for industrial intervention and buildings as glass facades, windows,
doors, and others.
In this article,
we will learn how to make glass, and materials used in the glass manufacture.
Materials
used in the manufacture of the glass:
Sand glass:
It is a basic
material in the glass industry,
and must
contain a large amount of silica more than 80 percent of the composition of sand
atoms,
so there are
certain types of sand used for the manufacture of glass, not all.
Sodium Oxide:
A chemical
that is incorporated into glass constituents,
which
controls the temperature during glass fusion and its ease of formation.
Feldspar:
This material
helps to give transparency to glass;it is available in abundance, and cheap
price.
Calcium oxide:
This material
gives the hardness to the glass after cooling.
Borax:
A mixture of
boron and sodium oxide, which helps to increase the melting rate of glass
materials,
in addition,
it gives the hardness of glass pieces,
for example, glass pieces containing large amounts of boron
is not easy
to break if exposed to heating and sudden cooling.
Secondary materials:
A group of
materials, added to the manufactured glass to improve its quality such as
materials that increase
transparency,
color materials, materials that increase fusion rates such as titanium, barium
oxide.
