Ceramic

A ceramic is any of the various hard, brittle, heat-resistant and corrosion-resistant materials made by shaping and then firing a nonmetallic mineral, such as clay, at a high temperature. Common examples are earthenware, porcelain, flower vase and brick.

The soil used to make clear white ceramic is called kaolin. To prepare ceramic mud is finely powdered using ball mill, mixed with water and converted to shape of vessel. The shaped mud is dried on mild sunlight. Then it is heated on furnace at suitable temperature. To make it non porous and shiny common salt powder is spread on heating. This process is called glazing. After that they are colored to make more attractive. Ceramics are non porous and so used make cup plate and other utensils, electric insulator, floor tiles, and even artificial joints and teeth. As they do not react with acid, base salt and other solvant the can be used to make vessel storing them
