Roman, 100 B.C - A.D. 100 Mosaic ribbon glass 1 3/4 x 3 1/2 in. Mosaic glass vessels were popular among Romans in the early Empire. Rods of colored glass were fused together so that the cross section created a design, often a floral motif or a roundel. The composite rods were cut into disks or slices, then arranged in a pattern in a two-part mold. When heated, the glass disks fused together to form the vessel.
