In this video created for the special exhibition Dig Deeper: Discovering an Ancient Glass Workshop, watch our Hot Glass team shape a glass vessel at a custom-built replica ancient glassblowing furnace.

This type of conical beaker with blue blobs was made and found at the 4th-century glassblowing workshop of Jalame, excavated by the Corning Museum of Glass and University of Missouri.

Conical Beaker with Blue Blobs, made between 300-399 in ancient Syro-Palestine. 79.1.159, gift of The Ruth Bryan Strauss Memorial Foundation. (https://glasscollection.cmog.org/obje...)
