Porcelain and ceramics
Porcelain and ceramics are classic materials for making cups, teapots and
tea-for-one sets.
The biggest differences between the two materials are in
their weight and appearance as well as the material composition.
Ceramic
consists mostly of clay that is fired at temperatures of 600 degrees or more.
Porcelain, on the other hand, is a form of ceramic but mainly consists of the
minerals kaolin (a fire-resistant decomposition product of feldspar), feldspar
and quartz. The amounts of the individual components vary and largely determine
the later hardness of the material. Porcelain is fired at high temperatures of
at least 1,200 degrees.
The oldest pottery was found in Siberia and is said to have been manufactured
in 13,000 BC. Reaching the high firing temperatures, which are necessary for the
production of porcelain, was not possible with primitive means. This is the
reason why porcelain was first made by Chinese master potters in the Tang
Dynasty (618 - 906 AD).
New Bone China and Bone China are forms of porcelain that are
characterized by high light transmission. Bone China contains bone ash, which
creates the transparency. The lower price of New Bone China is due to the use of
substitute materials such as talc. However, this does not necessarily mean that
New Bone China does not contain any bone ash at all.
