Top and bottom halves of a mold-made lamp are typical of lamps made in the Roman and Byzantine periods, fifth to third centuries B.C. The small projections at the ends of the lamps opposite the spouts served as handles. See photograph of limestone mold.

Specialists are now able to analyze and identify the clays native to different geographic regions. This ability often allows archaeologists to fix the place of manufacture of lamps.
