Glass ornaments such as bangles are widely distributed along trade routes between the East and West, indicating interactions and exchange between manufacturing and consumption sites. In the Persian Gulf region, numerous glass bangles have been excavated from late 2nd millennium CE contexts, but few of these have been studied with scientific analysis. Here, we report data on 56 representative samples from assemblages found at seven coastal sites of northern Qatar that date between the eighteenth and twentieth centuries CE, analysed by laser ablation–inductively coupled plasma–mass spectrometry (LA-ICP-MS). We identify six different glass compositions and discuss their raw materials and likely provenances, including one group from the Levant, one group from Mesopotamia and another two groups using different plant types as fluxes, with their sand source similar to Sasanian glasses from Central Iraq between the third and seventh centuries CE, and two high-alumina outliers associated with two Indian origins. The paper also compares the Qatar bangles with others from the Islamic world and India to discuss differences and similarities between them.

手镯等玻璃饰品广泛分布在东西方贸易路线上，表明制造地和消费地之间的互动和交流。在波斯湾地区，人们出土了许多公元二千年末的玻璃手镯，但其中很少有经过科学分析的。在这里，我们报告了在卡塔尔北部七个沿海地点发现的 18 世纪至 20 世纪之间的组合中的 56 个代表性样本的数据，并通过激光烧蚀电感耦合等离子体质谱 (LA-ICP-MS) 进行了分析。我们确定了六种不同的玻璃成分，并讨论了它们的原材料和可能的来源，其中一组来自黎凡特，一组来自美索不达米亚，另外两组使用不同的植物类型作为助熔剂，其沙源类似于来自伊拉克中部的萨珊玻璃。公元三世纪和七世纪，以及与两个印度起源相关的两个高铝异常值。该论文还将卡塔尔手镯与伊斯兰世界和印度的其他手镯进行了比较，讨论了它们之间的异同。
