Brick

The brick or also known under the term brick is the oldest artificial brick. The brick is a ceramic material which is burned from clayey loam.

The holes that are typical of bricks make the stone lighter on the one hand and, on the other hand, they serve as insulation through the penetrating air.

In order to increase the property of heat conduction, combustible materials such as pellets of cow material or sawdust are added to the raw mass, so that the material itself can be made porous.
