IELTS Writing Task 1 Topic 02

[expand title=”Answer”]

The provided graph outlines six consecutive steps on the  processes by which bricks are manufactured for the building industry.

First the raw material, clay, which was just below the surface of 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. Sand and water are added to make a homogeneous mixture, which is then either formed in molds 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 dozen 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. First they are kept at a moderate temperature of 200C – 1300C.Bhis 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.
