Roman glassware, as good as new

I have always been fascinated by Roman glassware in all its shapes, forms, and colors (see: The beauty of ancient glassware). 

Yet, I never came across glassware that survived in such pristine condition as that retrieved from the Cape Corse shipwreck in 2023. It lies on a Roman commercial route connecting Luna (modern Luni, Italy) to Massalia (modern Marseille), between Cape Corse in Corsica and the island of Capraia in Italy. It is the second known find with a cargo of almost exclusively glass, either in its raw state as blocks of various sizes or in the finished product of blown glass tableware.

The ship sank around 100 AD, and although it was discovered in 2013, we had to wait ten years for an international team of researchers to explore the wreck with two underwater drones. This modern equipment allowed them to retrieve the major part of its precious cargo using a very delicate claw system. 

A few thousand glass artifacts have been recovered, including drinking glasses, bottles, plates, cups, small bowls, and an ointment jar; also two bronze basins and several amphorae of different type such as oriental, the Beirut type, and four Gallic vessels. Combined with the raw glass, this find led the archaeologists to believe that the ship must have originated from a port in the Middle East, possibly Lebanon or Syria, and was headed towards the coast of Provence in Southern France. 

The Syrians were probably the first to have mastered the art of glass blowing as early as the 1^st century BC. Craftsmen from Sidon, Aleppo, Hama, and Palmyra developed the technique of using a blowpipe to shape molten glass, which allowed them to create objects faster than from cast glass. As a result, Syria became one of the most important glass production centers in the world, before, during, and after the Roman Empire. 

The main trade route started in Antioch (modern Antakya in Turkey) to supply the markets of Alexandria, Byzantium, and Rome, which, in turn, had steady connections with Massalia.

The question remains, how these thousands of glass objects were still undamaged and survived in such good conditions after resting at the bottom of the Mediterranean for two thousand years.
