A recent study analyzed waterproofing residues from a 2,200-year-old Roman shipwreck near Ilovik Island, Croatia, identifying distinct coating batches that indicate successive repairs. Researchers employed ATR-FTIR and GC-MS techniques on samples to determine organic materials, revealing the predominant use of conifer-derived pitch and beeswax mixtures. Pollen analysis provided geographic context, suggesting varied material sourcing linked to the vessel's repairs over time. This research underscores the importance of organic coatings for understanding ancient naval technology and shipbuilding traditions in the Adriatic region.
