13. History of
Earthenware
• Earthenware pottery has a long and rich history that
dates back thousands of years.
• Earthenware pottery was first utilized in China
during the Neolithic era (8,000–2,000 BCE), and it
was used both for economic and ceremonial
purposes.
• Chinese potters evolved advanced methods for
creating earthenware ceramics over time, including
celadon glazes, underglaze painting, and slip
ornamentation.
• Earthenware ceramics has a lengthy history in Japan
as well, with specimens dating back to the Jomon
era (14,000-300 BCE).
• Greek potters were renowned for their skill in making
finely painted and decorated earthenware vessels,
such as amphoras, kraters, and kylixes.
• In Rome, earthenware pottery was used for cooking,
storage, and serving, and was often decorated with
intricate relief designs.

14. Characteristics
of Earthenware
• Generally, unfired earthenware bodies
exhibit higher plasticity than most
whiteware bodies and hence are easier to
shape by RAM press, roller-head or potter's
wheel than bone china or porcelain.
• Due to its porosity, fired earthenware, with a
water absorption of 5-8%, must be glazed to
be watertight.
• Earthenware has lower mechanical
strength than bone china, porcelain or
stoneware, and consequently articles are
commonly made in thicker cross-section,
although they are still more easily chipped.
• Darker-coloured terracotta earthenware,
typically orange or red due to a
comparatively high content of iron oxides,
are widely used for flower pots, tiles and
some decorative and oven ware.

15. Raw Materials
for Earthenware
• China Clay
This is used to give earthenware
pottery a smoother texture and a
more refined finish.
• Ball Clay
This is a type of clay that is high in
organic materials and is added to
earthenware clay to improve its
plasticity.
• Feldspar
This is a mineral that is added to
earthenware clay to increase its
strength and durability.
• Quartz
This has an important role to
attenuate drying shrinkage.

17. 1. Preparation of Clay Body
• To ensure uniform moisture content in clay, kneading or wedging is
necessary, aiding in the removal of trapped air within the clay body.
This air elimination process, crucial for consistency, can be
achieved manually through wedging or by employing a vacuum pug
machine.
2. Shaping
a. Potter’s wheel
• In "throwing," a soft clay ball is centered on a turntable called
the wheel-head, rotated manually or with a motor. As the
wheel spins, the clay is gently shaped by pressing, squeezing,
and pulling upward and outward, forming a hollow object.
b. Jiggering & Jolleying
• In jiggering, the clay is first formed into a ball and then placed
on top of the rotating plaster mould. The jigger arm is then
used to apply pressure to the clay, forcing it to conform to the
shape of the mould.
• In jolleying, the clay is also formed into a ball, but it is then
placed inside the rotating mould. The jolly tool is used to apply
pressure to the clay, shaping it to the mould's form.
c. RAM Pressing
• RAM pressing compresses dry or slightly damp clay powder
into a desired shape using a hydraulic press. After firing in a
kiln, the product hardens into its final form. This method
enables the creation of large, intricate objects with precise
accuracy and consistency.

18. 3. Drying
• Before firing, clay articles undergo a crucial drying
process where water content is gradually removed. After
shaping, the clay is left to dry completely, causing it to
shrink and harden as the water evaporates. This drying
period must be conducted meticulously to prevent
cracking or warping, influenced by factors like humidity,
temperature, air circulation, and clay thickness.
4. Firing
• It is the process of heating the clay to a high
temperature in a kiln to harden it and create a finished
product. Firing also gives earthenware pottery its
unique colour and finish.
• Two types of firing are essential in pottery: bisque and
glaze firing.
a) Bisque firing, the initial stage, involves heating
the clay to 900-1000°C to harden it and eliminate
residual moisture.
b) In glaze firing, the bisque-fired pottery is coated
with a glass-like glaze and fired again at 1100-
1200°C, providing a smooth, glossy finish and
safeguarding it from environmental factors like
water.
5. Glazing
• Glazing is integral to earthenware pottery, providing a
glass-like coating that enhances both its aesthetic
appeal and durability. This process involves applying a
mixture of powdered glass and chemicals suspended in
liquid onto the pottery's surface. Glazing not only
creates a smooth, glossy finish but also renders the
pottery impermeable to water and other elements,
making it tougher.

19. Classification of
Earthenware
1. Clay Earthenware
• It consist mainly of clay or clay + sand.
• The clay in clay earthenware should
not be too high in iron oxide content.
2. Lime Earthenware
• It is made from clay which is rich in
calcareous minerals (lime bearing).
• It is highly porous and light weight.
3. Feldspathic Earthenware
• It consists of 5-20% feldspathic
minerals.
• It is dense as compared to lime
earthenware.

20. Classification of
Earthenware on basis
of colour of the fired
body
1. Delft Earthenware
• Delftware is a type of earthenware that is
glazed with a white tin glaze and decorated
with blue and white designs.
• It originated in the city of Delft in the
Netherlands.
2. Faience Earthenware
• Faience is a type of earthenware that is glazed
with SnO2 and often decorated with intricate
designs.
• It is typically red earthenware covered with a
white opaque glaze.
• It originated in France.

21. More types of
Earthenware
1. Terracotta Earthenware
• It is red earthenware also called as Baked
Earth.
• It is strong, fire resistant, porous in nature, has
excellent insulating properties.
• It can be glazed to make waterproof so that it
can be used as drainage material.
• They are used for both home decoration and
cooking purposes. Usually, the Terracotta pots
or vases are used by people to provide an
aesthetic look to their houses, but some
products are perfect for kitchen as well.
2. Slipware
• This is earthenware pottery decorated with
coloured slips.
• Slip is liquid clay that can be used to add color
and texture to pottery. The pot is then coated
with a transparent glaze.
• It is decorated using slip that had been
colored by oxides, such as copper,
manganese, or iron.

22. 3. Majolica
• Majolica is tin-glazed earthenware
pottery.
• The tin oxide makes the glaze an opaque
white color.
• Majolica pottery is bisque fired then the
glaze is applied. Decorations are then
painted onto the unfired glaze using
metal oxides. When the pieces are glaze
fired, the decorations sink into the molten
glaze and become part of the glaze
design. This is known as inglazing.
4. Creamware
• Creamware is a cream-colored
earthenware clay that has been painted
with a transparent lead glaze.
• It was first developed in the 18th Century
in Staffordshire in England.
• It was made from white clay that
contained flint to keep it from cracking as
it is being fired.

23. Challenges to Earthenware
Availability of Substitutes: There are
several alternatives available, like
glassware, advanced ceramics and others.
Moreover, there is a good demand for
synthetic pots and disposable tableware.
Disposable tableware is also in need due to
outdoor parties and a surge in food ordering
from restaurants.
Limited Versatility: While earthenware is
suitable for decorative items and certain
functional pieces, it may not be as durable
or suitable for high-temperature cooking or
extreme conditions.
Economic Factors: Fluctuations in raw
material costs, labor expenses, and market
demand can pose challenges to
earthenware producers, particularly small-
scale artisans and studios.

24. Importance of
Earthenware
• Their porous nature aids in spreading
heat throughout the food unlike other
materials. All dish cooked in clay pots
becomes soft and well prepared.
• One don’t have to use a lot of oil when
preparing excellent meals because
these cooking pots are quite heat
resistant. To conserve money and
maintain their health, many people
choose to utilize these clay pots.
• The recipes cooked in an earthenware
utensil will be quite delicious. There is a
scientific reason behind this fact. As
more time will be required to cook food
in a clay pot, the slow process will help
the food become tastier and more
nutritious.

25. Conclusion
