Small bottles and lidded pyxides (boxes) in mosaic and luxury gold-band glass were made during the Julio-Claudian period. But as glass-blowing became more widespread during the mid-1st century, they were quickly supplanted by free-blown versions, often in more transparent glass that allowed one to see the contents.
