A review of the available literature revealed that ancient glass in the underwater part of the Croatian Adriatic coast appears in a total of 44 sites. Most often glass occurs in ports, of which 29 were identified according to the glass finds, then on shipwrecks, of which 11 were found, and in four sites that could not be precisely defined. Looking at the overall glass repertoire of underwater sites in the Adriatic and taking into account the state of research and publications of glass materials, we can preliminarily conclude that the typical forms of Roman glass production from the 1st to the 5th centuries prevail in the Adriatic sea. The glass material can be chronologically divided into two units: glass from the period from the end of the 1st to the middle of the 2nd century and late antique glass. The majority of finds were produced on the Italian peninsula, but when processing the available data, a relatively large import from glass workshops in the eastern Mediterranean was also determined. Judging by the current situation in the field, the largest number of glass materials found can be classified as storage and transport dishes. The most common form of this category and also the most common form in the Adriatic Sea is the square bottle (Isings 50).
