Clay is a natural product from the earth formed from rock weathering. It is usually coloured by impurities especially iron oxide. Clay becomes wet when mixed with water. It can be moulded into different shapes in its wet form.
Clay can be processed to obtain other materials such as ceramics and glass. The clay must be prepared and any trace of sand, stones, metal scraps, plant materials, and all other impurities must be removes before using it for ceramics production.
Ceramics and glass products are commonly used in homes and offices.
