The so-called "thin-walled"vessels represent tableware pottery; small bowls and cups with fine and very thin walls, whichwe think were used as tableware drinking cups (vasa potoria) , as glass was not yet generallyused for this purpose. From a technical perspective, some samples of this kind of pottery probably represent the height of perfection reached by Roman potters using the fast wheel;with the small cups so-called "eggshell" due to the extreme thinness of its walls (less than 0.5 mm) considered an incredible technical achievement. The samples found in Lugo come from the foreign centres, present in the city from the very beginning of the settlement, such as the Italian or Gallic workshops, and later Hispanic ones, among which the Hispania Baetica workshops are the main exponent, situated in Southern Hispania and, above all, the neighbouring workshop of Melgar de Tera in Zamora, active since the last third of the First Century AD.
