Fired Brick

Fried bricks are developed in the Middle East. (c. 2000 B.C.E.)

In ancient times, brick houses were made first by compacting together wet mud and clay into slabs and leaving them to dry in the sun. Once solid, the bricks were piled up to fashion a basic building. However, the major problem with sun-dried bricks is that rainy weather can revert them to wet mud. It took brick makers a long time to arrive at a solution-buildings were constructed from dried mud blocks for more than 5000 years before the fired brick appeared.

Using a combination of clay, sand, and water, brick makers in the Middle East formed a pliable mass of matter called a clot. The clot was shaped in a wooden mold to create what is known as a “green” (that is, unfired) brick.

This was placed in a kiln and baked at nearly 3,600°F (2000°C), before being allowed to cool down into a permanently hard, more durable brick.

The fired brick enabled the construction of the first truly permanent structures-buildings much more resilient than those of mud bricks to harsh climates, changes in temperature, and weathering,

“And they said to one another, ‘Come, let us make bricks, and burn them thoroughly.’” Genesis 11:3

Fired bricks have been refined since they were first invented, the chemical ingredients of the clot mixture having been altered and optimized. Advances in technology have also made mass production possible. However, the premise behind the brick-making process remains exactly the same. CL
