History of Ceramics1
(Asadullah, Steel Town, Karachi)
The term 'ceramic' refers to a
non-metallic, inorganic solid. The substance takes on an easily moldable quality
on being exposed to extreme heat and subsequent cooling. The crystalline
structure of the material gives it a very amorphous or glassy appearance...
Ceramic is a crystalline material, inorganic in nature. The word 'ceramic' is
Greek in origin, and means 'pottery'. Today, the term is commonly used to
describe a material used in pottery. The earliest recorded ceramics were the
result of various mixtures and base - combinations, including clay. The
resultant non-metallic and inorganic solid base is now a common sight in artware
and the domestic and industrial segments of human development. The twentieth
century witnessed the design of amalgamated, new ceramic materials that are
still used extensively in the manufacture of semiconductors. Ceramic
engineering, as we know it today, is advanced and involves state-of-the-art
processes. The material is inert and inorganic, with a crystalline oxide base.
The resultant product is always brittle, but strong in compression. Ceramic is
able to withstand very high temperatures and chemical erosion and survives well
even in a strong caustic environment. Traditional raw materials that go into the
manufacture of ceramic include kaolinite, silicon carbide, tungsten carbide and
aluminum oxide or alumina.
The ceramics we know today date back to around 24,000 BC when the first clay
animals and pottery were found. It is believed that these were used in rituals
during that time and were very sacred. As civilization moved forward and people
needed certain utensils, ceramics made a very good tool.
About 10,000 years later there were many people who used tiles in Mesopotamia
and India and there were many vessels used for water and food storage. This
actually became an invention that was based on need.
Many historians believe that the Egyptians found a way to heat kiln like devices
and were able to put a colored glaze on their pottery. This was used for many
decorative pieces until around 1,500 BC when glass was discovered and there was
now a way to make pieces out of something different than ceramics.
One of the issues when people study the history of ceramics is that there are
different ways to look at these beautiful works. Some people made them to as
decorations and others made them as functional pieces. Since ceramics have to be
fired to harden, they have made a very good vessel for carrying many things.
Many different cultures worked with ceramics. For instance, the Chinese produced
three types of pottery --painted, black and carved. Much of what they did
happened during the Han Dynasty (206 B.C.-220 A.D) because by this time they had
developed a long history of firing kilns, so they were able to start producing
many varied pieces.
