The diagram below show the stages in the production of bricks.

The illustration demonstrates how

bricks

are produced.

Overall

, it is a 7 stage, man-made, linear process. It begins with clay, water and sand being added as raw materials and

finally

results in

bricks

being delivered. First of all, an excavator digs out clay from the ground and places it on a metal grid where it passes over a rolling machine in order to separate out small and big pieces. After that, sand and water are added and

this

is either added to a mould or cut by a wire to produce

bricks

. Following that, they are placed in an oven so that they can dry and are

subsequently

exposed to two different stages of heat in turn between 200-980 degrees Celsius in the first stage and 870-1300 degrees Celsius in the second. From

this

, the

bricks

are cooled in a cooling chamber for two to three days before they are packaged and

then

placed on a truck (which transports them)/so that they can be transported.
