Glass processing stages
Glass
passes through several stages in manufacturing:
Materials mixing stage:
In
this stage, the glass component materials are mixed in certain proportions and
then placed in special molds,
for
preparation for the second phase called the melting stage.
Melting
stage:
The
materials of the glass are inserted into high-temperature furnaces, until
liquid and viscous materials become high and formable.
The
types of furnaces used in the manufacture of glass vary depending on the type
of glass to manufactured,
and
the temperature of the molten materials varies according to the quantities used
in the manufacturing process.
Formation phase:
At
this stage the material cooled to a certain temperature in preparation for the
formation according
to
the type of glass required, and is formed either by hand blowing,
after
the placement of material molten in the form of molds, or inflatable mechanical
devices using the same glass.
The final stage of the formation:
At
this stage, the glass slowly cooled until it gets the appropriate hardness in
the furnaces for the cooling;
where
the pieces of glass for varying periods depending on the type of piece,
until
cooled temperature of the perimeter and as all manufactured materials, glass
needs finishing.
The
finished materials are not properly finished, so the glass is cleaned,
fine-grained
and then cut in case of need.
Some
materials are added to the glass mixture before the groom's glass from the
beginning;
to
give them certain properties.
For
example, the process of coloring the glass by adding certain materials to the
mixture at the beginning,
and
not the use of pigments, the iron oxide is added binary to give the glass
green,
while
cobalt is added to Example of glass production in blue.
The
glass has a large number of different types according to the uses and
applications,
for
which the glass is used, but glass is usually made of silica, which is made up
of sand.
The
glass is made by mixing sand with lime, soda and other materials by the
glass maker in certain quantities.
It
is important that the glass is free of impurities and contains a high
percentage of silica oxide,
and
then this mixture is heated in special furnaces, this mixture becomes liquid,
and
these furnaces are different from each other,
There
is a kiln oven used for the production of glass optics and decorations, Made of
fire bricks.
