The picture shows different stages in terms of how bricks are produced and delivered to customers. It is clear that there are seven different stages in the process of manufacturing bricks, beginning with digging clay from the ground by a digger, then producing bricks and ending with the delivery of bricks by a truck. At the first step in the process/beginning of the process, a digger is responsible for the excavation of clay which is then put on a metal grid to separate small species of the clay, and they are passed onto a roller where they are mixed with sand and water. Next, the clay can be shaped into bricks by either a wire cutter or a mould. At the fourth stage shown on the diagram, bricks are moved to a drying oven for 24 to 48 hours/one to two days. After that, such bricks are fired in a kiln at a moderate temperature (200ᵒC to 980ᵒC), then they are moved to another kiln to be fired at a higher temperature (870ᵒC to 1300ᵒC) before being put in a colling chamber for 48 to 72 hours/two to three days. Finally, the bricks are delivered by a big truck after they are packaged together.
