About Glass Fabrication
Glass fabricators and glass fabricator services are
any manufacturer involved in the fabrication of glass in any form. Glass
fabricator services use the process of forming glass to any specified
shape while heated. Float glass is the most common form of fabricated
glass. The molten glass coming from the furnace at a temperature of 1050°C
(1,922°F) is shaped at the approximate temperature range of 650 – 1,050óC.
The essential raw materials of glass include silica (sand), soda, limestone
and dolomite, silica being the major ingredient. Less common raw materials
are sodium sulphate, coal dust and cullet. These materials are often
molded into sheets of glass to be tempered later.
Other glass fabricator services use processes that provide different
preferred characteristics like thermal, aesthetic, acoustic, mechanical
or electrical. Mechanical reinforcement through chemical or thermal tempering
creates tempered safety glass. Alterations of the raw ingredients provide
special glasses, tinted glass and glass ceramics. Surface processing
like sanding or polishing creates glass for interior decorating. Combining
glass with other materials produces composites like laminated glass for
safety benefits, resin glass for acoustic insulation and gel glasses
for fire resistance. Coating the glass provides many benefits as well,
like mirrors, enameled glass, tinted glass and energy saving glass. There
is also a specialized coating of electron material that is microns thin,
which is found in glass required for electronic applications. Quartz
glass is composed almost entirely of pure silica and is utilized in various
technology applications.
Much modern glass is manufactured for other performance reasons, such
as to limit the amount of light, and therefore heat, which passes through.
Reflective glass is created by the addition of a thin layer of metal
or metallic oxide on the surface of the glass. This glass is used in
many large commercial buildings and skyscrapers. With its mirror-like
appearance, it both reflects and absorbs the amount of solar radiation
allowed to enter the building itself. This can lead to tremendous savings
in climate control costs. Low emissivity glass is a type of reflective
glass, which reduces heat loss indoors as well as provides UV protection
to guard against carpet and other furnishing damage. Insulating glass
is made from two or more layers of glass separated by a sealed air space.
This space reduces moisture from condensation and certain levels of noise.
When looking for glass fabricators it is important to consider things
like size, especially the thickness, safety and aesthetic issues and
whether bent glass is needed. The pharmaceutical and research and development
sectors of industries rely on the use of testing glass such as vials
and beakers. When a glass product for a technological or laboratory application
is used, clarity and purity are important factors. Glass fabricators
often specialize in only one or two types of glass. Being aware of their
range and area of specialization will ensure quality product and services.

Types of Glass Fabrication
- is
glassware shaped and created by air pressure; this has commonly been
done by mouth in the past or by compressed air through a metal pipe.
Pieces are often made in mass quantities such as bottles, via a highly
automated system, which both moves and injects air into the glass gob
to form the finished piece.
- is any glass object decorated by cutting or grinding facets
and is for purely decorative purposes, like decorative plates or other
assorted knick knacks.
- is
a wider classification of glass that includes wired and tempered glass.
The main processes by which flat glass is made are the rolled and float
glass procedures: rolled glass is made when a continuous stream of molten
glass is poured between water-cooled rollers, while the float glass
process is the most widely used process and consists of the glass being
held in a chemically controlled atmosphere at a high temperature for
a long enough time for the surface to become flat and parallel.
- is the process of shaping glass with air.
- includes various methods, including diamond saw cutting, thermal or hot cutting, score and break cutting, and laser cutting.
- are long, cylinder-shaped pieces of glass.
- is a cylinder made of glass material.
-
is exposed to a heating and cooling cycle and is typically doubly strong
as standard annealed float glass of equal measurements. Breakage
of this glass results in larger pieces than with completely tempered
glass.
-
is the result of melted silica, and it can resist extreme or quickly
changing temperatures and is typically transparent to ultraviolet radiation.
This product is utilized in fiber optics, analytical instruments, semiconductor
technologies and casting processes.
-
is a type of safety glass that is heat treated and approximately five
times stronger than similarly measured glass standard annealed float
glass; breakage results in small, rectangular-like pieces, beneficial
for general and safety glazing like storm doors, building entrances,
sliding doors and bath and shower doors.
- is a product with various patterned and uneven surfaces.
- is
created by inserting a wire mesh into sheets of glass, which has
a resistance to impact forces like normal glass,
but
wire holds broken pieces in place. This has customarily been
accepted as inexpensive fire safety glass.
