The memory and the signs of the ancient trade routes of the Mediterranean, at the time of the Phoenicians before and then the Romans, remain in the finds of the wrecks of ships loaded with products of exchange. The most significant trace, even in our imagination, is the amphora for the containment of foodstuffs, especially oil and wine. In Mediterranean civilizations where baked clay was the predominant material used for the production of containers that were used for transport and storage. Already the Phoenicians used to vinify in buried clay vessels; then it was the Greeks first and the Romans later to continue in this technique. The latter made extensive use of large, spherical, terracotta containers called dolia (singular Dolium). There are also numerous important discoveries in the regions of present-day Georgia where larger jars and the capacity of thousands of liters were buried in dedicated rooms. The ancient Romans called this Opus Signinum material Latin term derived from the city of Segni (Signa) near Rome, where according to ancient sources it was invented. In the 1st century a.c. Vitruvius describes its manufacture and use in its treatise “De Architectura”. The ancient mixture was used to cover the aqueducts, cisterns, thermal baths. Depending on the grain sizes of the materials used in the application technique for the various types of use, the permeability level of the compound was determined.
