Glasswork in the Early Byzantine period
  Glass was another popular material for inexpensive utilitarian objects, such as cups, pitchers, cosmetics' bottles and oil-containers for chandeliers. Most Early Byzantine glass vessels were made by blowing, a method used to produce quickly a large number of thin-walled, transparent objects. Some pieces were blown into molds decorated with Christian or Jewish motifs. Luxury glass includes dishes and bowls with gold-foil medallions as centrepieces, the bases of which are frequently found in catacombs. Glass was also used for mosaic tesserae, window panes, beads and mirrors.
