Ceramic Dinnerware Set

Ceramic dinnerware ranges from the old fashioned dinnerware to the most latest china dinnerware. This provides a brief knowledge
about the popular materials and terminology used. The chemical properties of the raw material used determines its strength, porosity and glassiness of the finished dinnerware.
Physical Aspects.
Absorption. One of the most
important aspect with the help of which classification of ceramic
dinnerware is done. Fine china, porcelain, bone china, restaurant china, stoneware
and ironstoneware have an absorption rate of 0.5 percent, while Semivitreous
dinnerware has 4-9 percent and earthenware has 10-15 percent.
Vitrification. All
unfired clay wares are baked at the high temperature, which results in hardness
and glossiness of the ware. Full vitrification is done at temperatures of 2000
F or above and causes very low porosity
Flint. Has
a low iron content. The flint generally used is ground quartz sand.
Clay. Provides
plasticity and strength. Varieties of white clays are used, such as including kaolins, china clays
and ball clays.
and fluxes. This
is a group of rock-forming minerals found inside earth’ crust. It is the
primary flux used. The fluxes develop the glassy phase and provide vitrification
and translucency. Some other fluxes are potash-albite spars and talc.
Alumina. Adds
strength, thermal shock resistance, whiteness and reduction of flaws to the ceramic ware. It
occurs in clays, kaolins, feldspars and talcs.
Ware Varieties.
Pottery is
a generic term meaning all clay pieces baked in a kiln.
Greenware is
a generic term meaning all unfired clay pieces.
Earthenware is
made by baking at low temperatures, which makes an opaque piece that is not as
strong as stoneware or china. It can be
either glazed or unglazed.
Stoneware is
a nonporous ceramic made up of unprocessed clays and flux additives. It is usually colored and
includes iron in the clay.
China is
similar to porcelain, but is not translucent and is off-white.
China is
thin, translucent, vitrified dinnerware composed of flint, clay and flux
materials. It is thin, translucent, vitrified, highest quality and baked twice.
Porcelain is
a hard, nonporous, strong white dinnerware that is slightly translucent.
China is
a type of china made with bone ash for greater translucency, whiteness and
China is
American china that is made by combination of fine china and porcelain and is
designed for commercial restaurant use.
dinnerware is
strengthened, colored, formed and looks like
china. This has low porosity, chip and break resistant.
