title: Provenance studies of Günsenin IV amphorae from the Novy Svet Shipwreck
abstract: The origin of Günsenin IV amphorae from the “Novy Svet Late Byzantine shipwreck” (Crimea) was investigated using chemical and petrographic analyses. Besides a main group, several small sub-groups indicate multiple workshops. The former shares similar features with examples of Günsenin I amphorae, including some from the Ganos workshops (Turkey), suggesting that the clayey material they were made of comes from the same geological formations. Petrographic analyses further narrows down the area to
