TEL MUTUBIS, EGYPT—A survey conducted in Egypt’s Nile Delta at the site of Tell Mutubis has unearthed evidence for glassmaking in the Roman period. Excavators have found glass shards and glass vessels, indicating, lead archaeologist Penny Wilson told the Cairo Post, that “furnaces used to manufacture glass existed in this area.” A number of coins found at the site have confirmed the dating to the Roman era, which lasted from the fourth century B.C. to the fourth century A.D.
