In the history of bricks, at least the age of bricks goes back to more than 5000 years ago, the first bricks that were produced were made of Clay and straw, which were poured into rectangular molds and left to dry. Brick in Iran is very old.

The production and use of bricks actually became popular from Western Asia, then it was transferred to Egypt, India and other parts of the world. In Iran, archeologists have observed the remains of brick kilns dating back more than 6000 years around Shush and Silk Kashan hills.

Brick is one of the oldest, most durable and widely used building materials. From the past several centuries until today, due to its durability and high resistance, brick has been used in the construction of many structures. Brick production also has a special process. The reason for the high durability of the brick is that it is fired in a 2000 degree furnace. Many early forms of brick were unburnt bricks that were naturally dried by sunlight and were also known as sun-dried bricks. Usually these bricks have less resistance. So they are not used in modern construction and civil engineering. Bricks are produced from different materials and for different purposes. In the following, we will examine the methods of brick production together.

Bricks made of clay have been used for at least 5,000 years. Apparently, for the first time, it was used to build cities in the Mesopotamia and the Indus Valley in Pakistan. At first, people mixed clay and straw by kicking them to make bricks. Then the prepared mixture was poured into rectangular molds and dried in the sun.
