Analysis of Roman shipwreck’s coatings tells story of its time on the seas

Chemical analysis of a Roman shipwreck’s coatings reveals that its crew waterproofed the vessel multiple times, using different materials depending on the ship’s location. The researchers behind the work say that the findings provide a better picture of the ship’s history by ‘understanding the techniques used, the phases of its life, its movements, its environment – going far beyond a simple description of the materials’.
