In 1963, archaeologists from the Corning Museum of Glass in upstate New York began excavations in an ancient Levantine town called Jalame, in today’s Israel. For eight years they uncovered objects—many of which were brought back to the Corning—related to the production of glass in the Late Roman Empire. Most of the pieces produced in the Jalame workshop were workaday, monochrome items, but a few were more luxurious, such as a conical beaker decorated with blue dots (from copper). Untreated glass is naturally green or blue, from the iron found in sand, so the glass for this beaker would have to have been de-colorized with manganese. “The Jalame excavation was transformative because it was really the first scientific investigation of a glass workshop from antiquity,” says Katherine Larson, the guest for this episode of Curious Objects and curator of the exhibition "Dig Deeper: Discovering an Ancient Glass Workshop in Corning."
