 Summary:
 This paper provides some new information about old leading technologies and possibilities of large-format brick production in today's conditions. The production of masonry elements can be from clay that has been shaped and dried, or after drying, such clay has also been baked. The most sensitive phase in the production of clay products is the drying of the clay. In the drying phase, such stress states can occur in the clay that would lead to the appearance of cracks and warping. It is for these reasons that today the clay brick format has been reduced to the dimensions of 25 x 12 x 6.5 cm. The formats of bricks and baked bricks that were made thousands of years ago, until several hundred years ago, were several times larger than today's format, completely correct and without cracks and twisting. The old builders used micro-reinforcement in the form of fibers, which they mixed into the clay and thus prevented the appearance of cracks and warping. These technologies have been tested and confirmed in the works of students on the subjects of Traditional Materials and Masonry Structures for several years at the Faculty of Civil Engineering in Subotica. These projects were done in collaboration with the world leader in the production of baked clay products, Wienerberger d.o.o. Kanjiža.
