TRANSCRIPT
Appropriate refined clay is converted to the desired shape. After drying it is
placed in a kiln and then fired. The typical firing temperature ranges from around
600 °C to 1000 °C. The iron content in mix reacting with oxygen during firing,
gives the fired body a reddish color, though the overall color varies widely across
shades of yellow, orange, buff, red, "terracotta", pink, grey or brown.
In some contexts, such as Roman figurines, white-colored terracotta is known
as pipeclay, as these clays were later used for smoking pipes, normally made of
clay, until the 19th century.
Fired terracotta is porous, but surface-burnishing of the body before firing can
decrease its porousness and a layer of glaze can make it watertight. It is suitable
for use below ground to carry pressurized water (an archaic use), for garden
pots or building decoration in many environments, and for oil containers, oil
lamps, or ovens.
TERRACOTTA / POTTERY
MAKING PROCESS
Preparing the Clay
Terra cotta is made from a number of
elements, mainly clay and water. It is
crucial to follow the powdered mix
instructions to add just the right
amount of water. Pour the mix into a
container, cover with a lid, and shake
well. Then, open the lid to allow the
clay access to air so it can become
well-hydrated. At this point there
should be little or ideally no lumps
left.
Once the clay has been composed,
you have to knead it. This can be
done just like preparing dough. This
process wil l homogenize and
eliminate any air bubbles.
Shaping
Once the clay has been mixed, and you are satisfied
with the consistency achieved, start the shaping
process. To shape the item, the potter uses hands or
utilize a cast or pottery wheel. Make sure to keep it
warm to allow for easier handling. Start coiling the clay
material upwards, until you reach the height you want,
little by little. To produce a smooth result, use your
thumb and forefinger. For separate pieces which are to
be attached to one another, make sure that they are of a
similar consistency and dampness. Keep a cup of
water at hand to dampen the material
as you go along if needed.
Firing
The final step is to fire the creation in a
pottery kiln. Make sure that it has dried
first. The firing time required will vary
according to the temperature and the
size of the creation. Exercise caution
when handling it after it’s been fired
and use kiln tongs to handle the fired material.
