Recent Investigations Of Early Roman Cameo Glass - Part 2. X-Ray Fluorescence Analyses Induced By Synchrotron Radiation

The elemental composition of 14 Roman cameo glass ragments was measured quantitatively by X-ray fluorescence analysis induced by synchrotron radiation. The study was intended to learn more about the possible manufacturing techniques of these glasses. In the white cameo decor of nine fragments all belonging to vessels a higher lead oxide concentration was detected compared to the coloured body. In contrast, lead oxide is not enhanced in the remaining five fragments from cameo disks or plates.
