    Reference answer


    The process by which bricks are manufactured for the building industry can be outlined in seven consecutive steps. [Crack IELTS with Rob] First, the raw material, clay, which was just below the surface of the soil in certain clay-rich areas, has to be dug up by a digger.


    Then the lumps of clay are placed on a metal grid in order to break up the big chunks of clay into much smaller areas, which fall through the metal grid onto a roller, whose motion further segregates the bits of clay. [Crack IELTS with Rob] Sand and water are added to make a homogenous mixture, which is then either formed in moulds or cut into brick-shaped pieces by means of a wire cutter.


    Those fresh bricks are then kept in a drying oven for at least 24 and a maximum of 48 hours, several dozens if not hundreds of bricks at a time. The dried bricks are then transferred to a so-called kiln, another type of high-temperature oven. [Crack IELTS with Rob] First, they are kept at a moderate temperature of 200 degrees -1300 degrees of Celcius. This process is followed by cooling down the finished bricks for 48 to 72 hours in a cooling chamber.


    Once the bricks have cooled down and have become hard, they get packaged and delivered to their final destination, be it a building site or storage.
