- Porcelain is a
ceramic material made by heating refined minerals, often including clay
in the form of kaolinite, to high temperatures in a kiln at temperatures
between 1,200 °C (2,192 °F) and 1,400 °C (2,552 °F). The toughness,
strength, and translucence of porcelain arise mainly from the formation
at these high temperatures of glass and the mineral mullite within the
fired body.
- Porcelain was named
after its resemblance to the white, shiny cowry, called in old Italian
porcella, because the curved shape of its upper surface resembles the
curve of a pig's back.
- Properties
associated with porcelain include low permeability and elasticity; high
strength, hardness, glassiness, durability, whiteness, translucence,
resonance, brittleness; high resistance to chemical attack and thermal
shock.
- Western porcelain is
generally divided into the three main categories of hard-paste,
soft-paste and bone china, depending on the composition
of the
paste.
- The primary
components of porcelain are clays, feldspar or flint, and silica, all
characterized by small particle size. To create different types of
porcelain, craftspeople combine these raw materials in varying
proportions until they obtain the desired green (unfired) and fired
properties.
- After the raw
materials are selected and the desired amounts weighed, they go through
a series of preparation steps. First, they are crushed and purified.
Next, they are mixed together before being subjected to one of four
forming processes—soft plastic forming, stiff plastic forming, pressing,
or casting; the choice depends upon the type of ware being produced.
- After the porcelain
has been formed, it is subjected to a final purification process,
bisque-firing, before being glazed. Glaze is a layer of decorative glass
applied to and fired onto a ceramic body. The final manufacturing phase
is firing, a heating step that takes place in a type of oven called a
kiln.
- Porcelain is used to
make table, kitchen, sanitary and decorative wares, objects of fine art
and tiles. Its high resistance to the passage of electricity makes
porcelain an excellent insulating material and it is widely used for
high-voltage insulators. It is also used in dentistry to make false
teeth, caps and crowns.
- High-quality
porcelain art and dinnerware will continue to enhance the culture.
Improvements in manufacturing will continue to increase both
productivity and energy efficiency. For instance, a German kiln
manufacturer has developed a prefabricated tunnel kiln for fast firing
high-quality porcelain in less than 5 hours. Firing is achieved by
partly reducing atmosphere at a maximum firing temperature of 2,555
degrees Fahrenheit (1,400 degrees Celsius). The kiln uses
high-velocity burners and an automatic control system, producing 23,000
pounds (11,500 kilograms) of porcelain in 24 hours.
- Over the past years,
domestic production of Porcelain in Russia has declined drastically. The
decay in the porcelain industry is wrapped up with a tradition of
producers having placed the pieces with international awards in museum
cases, instead of using them for mass production. The result is that the
Russian porcelain industry is trying hard to compete with overseas
suppliers in terms of quantity, with hand-painted tea sets, for example,
sold for as little as US$15 each.
- The lower-end market
has already been taken over by cheap imports from Ukraine (a traditional
source of porcelain clay since the 1740s) and
more recently, China.
The harsh fact is that consumers prefer cheap chinaware to the
traditional hand-painted, modestly-priced but still delicately
transparent porcelain on offer from local factories.
