The diagram illustrates how bricks are made. Overall, it is a linear process, involving three main phases: manufacturing, drying and cooling, and packing for sale.
Initially, the clay is dug with a special machine called a digger. Then, it is gridded with metal grid to make the clay more drained and reduce the risk of root. After sending the clay by a roller, it is given a shape of brick using two methods: either with wire cutter or mould.
The second phase includes drying in the oven, which takes 24-48 hours, and cooling. Heat in a kiln with a high scale of temperatures, generally, consists two steps: moderate, warming with 200-980 degrees Celsius, and high, heating them by 870-1300 degrees Celsius. After that steps, bricks must be cooled over a period of 48 to 72 hours before they can be safely handled, transported, and used in construction.
Finally, after preparing the bricks perfectly, they are packaged and delivered to the construction sites by trucks.
