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.
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.
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:
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.
