What is the stoneware and earthenware?

Answer 1

Stoneware is fired at very high temperatures so that it becomes non-porous, almost like glass. The heat literally melts down the microscopic holes until it's impervious. Earthenware is fired at lower temperatures and is porous. It can also be easily scratched and damaged, whereas stoneware resists scratches very, very well.

Stoneware is for all practical purposes

man-made stone. Just with other types

of pottery or china, clay has been formed

into a desired shaped and fired in a kiln to

make it hard and glass-like in its imperviousness

to liquids.

Earthenware, for example, is not

impervious and will absorb liquids. Porcelain

china is said to be a variety of stoneware

although always whiter in appearance.

In its natural state stoneware will appear gray

or brown, but typically glazes will be applied

before firing to make the stoneware any color

the manufacturer and consumer desires.

For this reason, on its surface, stoneware can

be difficult to tell apart from porcelain china.

Some consumers like natural, earth tones that

go well with any color of food and any home décor.

There are also many bright solid colors and bright

patterns available, including ornately hand-painted

designs that rival the finest of china.

Answer 2

The difference is the density. High fired pottery is very vitreous and will hold water. The clay particles have undergone more of a chemical bonding with each other , due to the high firing temperature. Low fired or earthenware pottery is less dense, or porous, allowing moisture to eventually seep through.

Answer 3

"Ceramics", in general, is science of working with clay and pottery.

At present, it is called to the art and technique of fabrication of objects and parts from clay with factor of heat; now, it is not limited to table ware like bowl, dish, pot, ...

Miscellaneous materials, are prepared with various methods from soil resources, consequently the word of "Ceramic" is converted to a more concise manufactures.

To have a clear definition, first, various kind of ceramic should be classified, considering its construction and make.

Kind of ceramic:

A) Structure:

1-Triaxial or compound body: These bodies are formed of three kinds of materials. The main part of those bodies consists of "Caoline", "Quartz" and "Feldspot".

2-Non tri-axial bodies: Consist of an irregular structure and a quantity of other ingredients.

B) Ceramic by make:

1-Earthenware

2-Stoneware

3-China

4-Porcelain

5-Special ceramics

Species of Earthenware

Considering to its combinations, earthenware is divided in a few species:

1-Natural, derived of one material with the most un-purity.

2-Fine, combined of more or less adhesive materials, having minimum un-purity.

3-Talc, is an earthenware with high strength, a very desired product due to tiny grains of talc.

4-Semi-Vitruse, is a combination of three main materials and has a medium porosity. Absorption of this earthenware is low and sometimes, it is taken by mistake with true china ware, owing to its transparency and fragility.

Answer 4

Earthenware clay is darker and heavier and fired at a lower temperature. Stoneware is fired at a higher temperature and doesn't chip and crack as easily.

Answer 5

Stoneware is a kind of ceramic. It tends to be thicker and heavier than porcelain or china, so it's more durable.
