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.
