Accent
Pottery
Polish Accent Pottery is basically
earthenware manufactured from clay. Clay is shaped into
different required objects, a majority of them as pots and the
shaped objects are heated in kiln at very high temperatures.
This heating react on the clay to harden the objects, set and
retain the shapes permanently and also make the objects strong.
Pottery can be seen all over the world; however, each region
has its own uniqueness due to the properties of the clay being
used to produce the wares. Generally, wares for specific
purposes are made from clay mixed with other minerals.
The pottery making process starts with removing the air
trapped within the clay lump prior to the shaping process.
Removal of air is known as de-airing and this is accomplished
either by a vacuum pug machine or manually by wedging. Wedging
or packing the clay by repeated beating and rolling also help
in distribution of the moisture content in clay uniformly.
After these two steps of de-airing and wedging, the clay is now
ready for shaping through a variety of techniques. The shaped
clay is allowed to dry before loading into a kiln for
firing.
The drying process has many stages. The stage when the
shaped clay is about 75-85% dry is referred as leather-hard. In
the leather-hard stage, the clay is quite firm and is only
slightly flexible. This is the stage in which trimming and
attachment of handle etc. are carried out. When the moisture
content of the clay reaches 0%, the clay is said to be in
'bone-dry' stage. Bone-dry clay object prior to kiln firing is
known as greenware and in this stage the object is extremely
fragile and can be broken very easily.
The famous Polish Accent Pottery is
readied for kiln firing after the initial stages of mixing clay
and other ingredients, shaping the clay to the required objects
and after applying the ornamental decorations. In many other
regions of the world the clay and minerals are of lesser
quality than available in Poland, and the pottery articles in
these regions are fired in 800 to 1200 degrees Fahrenheit
temperature.
The resultant pottery articles are often porous and these
products are called terra cotta or earthenware. However, the
Polish Pottery, manufactured from clay deposits of Lower
Silesia, is fired at nearly 2000 degrees Fahrenheit and this
high temperature firing give the Polish Pottery that extra
toughness and age-defying quality. A glaze finish is given to
the pottery by a thin coat of material which turns into a glass
coating during firing. Decorative paintings are inside the
glass coating which ensures that the pottery is non-toxic and
will not deteriorate due to abrasions.
The process of firing twice makes the Polish Accent Pottery highly durable, provide
resistance to cracks or chipping and suitable for use in
microwave, dishwasher, oven and freezer.
