Methods of Manufacturing
Clay bricks are formed in a mould (the soft mud method), or more frequently in commercial mass production by extruding clay through a die and then wire-cutting them to the desired size (the stiff mud process). The shaped clay is then dried and fired either by burning in a kiln or sometimes, in warm and sunny countries, by sun-drying to achieve the final, desired strength.
The action of heat gives rise to a sintering process that causes the clay particles to fuse and thus develops extremely strong ceramic bonds in the burnt clay bodies. Such bonds are highly stable. As a result, bricks can withstand the severe weathering actions and are inert to almost all normal chemical attacks.
