In this research project, 17 samples of glass artifacts recovered from the historic port of Najīrom in the Persian Gulf-dating to the early and middle Islamic periods-were analyzed using the micro-PIXE technique for elemental composition. The studied glass objects include 8 glass bracelets and 9 glass vessels. The primary question addressed is: What raw materials were used to manufacture these glass artifacts, and were the same materials used for both the bracelets and the vessels? Was the fluxing agent derived from the mineral natron or from plant ash? Were the glass artifacts found at Najīrom locally produced, or were they imported through trade and exchange? Another objective of this study is to examine the quality and purity of the silica sources, as well as the diversity of colorants and decolorizing agents used in the manufacturing process. The results of the elemental composition analysis indicate that, with the exception of one vessel, all analyzed glass samples from the site fall into the silica–soda–lime glass type made with plant ash. However, significant variations in the weight percentages of magnesium oxide and potassium oxide in the glass compositions clearly suggest that different raw materials were used for the bracelets and vessels found at the historic port of Najīrom. Moreover, the weight percentages of elements introduced into the glass from the silica source reveal that the bracelets and vessels were produced using different silica sources, which may indicate different production sites for these glass artifacts. Accordingly, it is possible that the samples recovered from Najīrom were manufactured in various workshops within and outside of Iran, and brought to the port through trade and exchange. A notable example of an imported object is a perfume bottle, which falls into the natron glass type and was likely produced in the eastern Mediterranean region, in countries such as Egypt or Palestine.
