It is the science of pottery which may be defined as the objects made from thespecial type of clay, hydrated aluminum silicate (Al2O3.SiO2.2H2O), feldspar and silicates. The pure fine white clay made of feldspar is called Kaolin of China clay. It is used in ceramics.

Glazing:

Some articles made by ceramics are coated with tin oxide or lead oxide and heated again. The coating forms a thin layer over the surface. This process is termed as glazing. Glazing makes the surface of ceramics smooth, attractive and waterproof.

Properties of ceramics:

  1. It can withstand high temperature.
  2. They are not affected by acid, alkali or other chemicals.
  3. They are poor conductor of heat and electricity.
  4. They are hard and brittle but attractive.

Uses:

  1. It is used for making household pottery, jugs, tiles, bowls, cups, sinks, etc
  2. Being poor conductor, they are used for making furnace of insulators in TV sets, electric fittings, etc.
  3. They are used for making artificial teeth, bone joints and porcelain.

Questions and Answers
Ceramics is the special type of clay containing a compound of carbon, nitrogen, silica and oxygen.
The ceramics utensils are commonly used because they do not absorb water and not affected by acid, base, salt and high temperature.

Any two uses of ceramics are as follows:

  1. It can be used to make artificial teeth, bones etc.
  2. Porcelain is bad conductor so , it is used to make different kinds of electrical appliances.

When glaze is added in ceramics, the surface becomes smooth and attractive. Hence, it gives attractive look to the ceramics.

The nature of ceramics are as follows:
1) It has attractive smooth surface, thus can be used to make decorative objects.
2) It disperses equal amount of heat all around its surface.
