The paper summarizes the archaeometric investigations performed on the glass beads and vessels discovered in tomb nr. 9 of Nora cemetery. We discuss the forming techniques, the raw materials used and the provenance of the base glass. LA-ICP-MS data showed that the 26 samples analyzed are natron glasses. The opacifiers and colorants used in the production of the different glasses have been identified: blue glasses show Co and Cu; the only light blue bead has Ca antimoniates and Cu; white and yellow glasses are characterized by Ca and Pb antimoniates, respectively. Pb antimoniates are also associated with Cu in the opaque turquoise bead in leaded glass. The dark color of the pendant is due to high Fe, while the transparent brown bead presents the Fe-S complex. The trace elements suggest a Levantine origin of the sands, with the only doubt for one opaque turquoise bead.

Abstract
The paper summarizes the archaeometric investigations performed on the glass beads and vessels discovered in tomb nr. 9 of Nora cemetery. We discuss the forming techniques, the raw materials used and the provenance of the base glass. LA-ICP-MS data showed that the 26 samples analyzed are natron glasses. The opacifiers and colorants used in the production of the different glasses have been identified: blue glasses show Co and Cu; the only light blue bead has Ca antimoniates and Cu; white and yellow glasses are characterized by Ca and Pb antimoniates, respectively. Pb antimoniates are also associated with Cu in the opaque turquoise bead in leaded glass. The dark color of the pendant is due to high Fe, while the transparent brown bead presents the Fe-S complex. The trace elements suggest a Levantine origin of the sands, with the only doubt for one opaque turquoise bead.
