The diagram illustrates the process that is used to manufacture bricks for the building industry.

 Summarize the information by selecting and reporting the main features and make comparisons where relevant.

The flow chart shows how bricks are produced for, and delivered to the building industry.

Overall, there are 7 stages in the whole brick producing process, beginning with clay excavation and ending with the delivery of the bricks to the customers.

Firstly, clay is dug up by using a big digger.

To get rid of the oversized pieces, clay is placed on a metal grid and small pieces drop onto a large roller.

 At the next stage, sand and water are added to the clay.

After the bricks are shaped by using a wire cutter or a mould, they are moved to a drying oven for 24 to 48 hours.

Those bricks are then fired in a special kiln at a moderate temperature (200c - 980c) at the fourth step.

Afterwards, they continue to be heated for the second time at a higher temperature (870c - 1300c) in another kiln.

Before being packaged at the sixth stage, the bricks are treated in a cooling chamber for 48 to 72 hours.

The entire brick producing process concludes after the bricks are delivered to customers.
