The Nd isotopic composition of an ancient glass is typical of the (heavy) non-quartz fraction in the silica raw material. The Sr isotopic
composition is considered typical for the lime component in the raw material. In the case of natron glass, this is mostly attributed to shell or
limestone in the silica sand. In this study, 1st to 5th and 6th to 7th century AD glass from Sagalassos is compared to the typical signature of 4th to
8th century AD primary glass with a known production location in Egypt and Syro-Palestine. The results suggest a difference in glass supply to
Sagalassos between both periods, and that glass was produced in the eastern and western Mediterranean area at least before the 6th century AD.
