ABSTRACT
The introduction in Abruzzi of the first furnaces Hoffman, at the beginning of the 20th Century, allowed a wider use of the baked brick.
As a consequence, the production costs decreased and the bricks started to be used for some important portions of the earth houses, such as the basement and the edge beam, or the reveals of the doors and the windows. This shows that the ancient builders were acknowledged about the issues of this tool.
