You should spend about 20 minutes on this task. The diagram below shows the process by which bricks are manufactured for the building industry. Summarise the information by selecting and reporting the main features, and make comparisons where relevant. Write at least 150 words.

The process depicts the manufacturing of bricks. Overall, there are 7 major steps, beginning with the digging stage and ending up with bricks are ready to be delivered. To begin, clay will be gathered with a view to be used as the main ingredient of making bricks. After that, the clay transported to the factory has to be sifted through a large metal grid, and be collected on a roller. Then, the sifted clay would be mixed up with decent amount of sand and water so as to create a suitable mixture, following by either being moulded or using wire cutter in order to form a particular shape. Moving on, the substance finished the shaping step will be put into an over with an aim of absorbing the remaining water at about 1 to 2 days. The bricks are removed and placed in a kilning machine with the first heat level between 200 and 980 degrees, and the second heat level approximately from 870 to 3000 degrees. Lastly, in sequence to being cooled down in a cooling chamber for 48 to 72 hours, those bricks need to undergo package stage before distributing to constructions or consumers.
