Dataset on Metallurgical Practices at Dhaskalio, Keros: SEM-EDS Analysis of Slag and Prills

The dataset includes the chemical composition of slag phases, as well as copper and sulphide prills observed in the microstructures of slag samples from the Early Cycladic complex of Dhaskalio, Keros, obtained through SEM-EDS analysis. This data offers new insights into the range of metallurgical activities conducted at the site. Evidence of smelting has been documented within the settlement itself, indicating the production of unalloyed copper and arsenical copper enriched with nickel and lead. These activities were closely connected to pyrotechnological operations at the nearby smelting site on the Kavos Promontory. Together, Dhaskalio and Kavos represent the only known primary metal production site of the Early Cycladic period outside the metalliferous western Cyclades, which hosted large-scale smelting activities. Secondary metalworking, such as refining and melting arsenical copper, is well-represented in Dhaskalio's material record. Limited evidence of tin-working suggests a focus on recycling practices, likely of tin-bronze scrap metal.本数据集涵盖了通过扫描电子显微镜-能谱仪（SEM-EDS）分析获取的凯罗斯岛（Keros）达斯卡利奥（Dhaskalio）早期基克拉迪建筑群遗址炉渣样品微观结构中观测到的炉渣相化学成分，以及铜粒与硫化物小球体。该数据为揭示该遗址所开展的各类冶金活动提供了全新研究视角。该定居点内部已发现冶炼活动的相关实证，表明当时曾生产纯铜与富含镍、铅的砷铜。此类活动与邻近卡沃斯海岬（Kavos Promontory）冶炼遗址的火法工艺作业紧密关联。达斯卡利奥与卡沃斯共同构成了目前已知的、位于富含金属矿产的西部基克拉迪群岛之外的唯一一处早期基克拉迪时期原生金属生产遗址，该遗址曾开展大规模冶炼活动。达斯卡利奥的物质遗存中充分体现了次级金属加工活动，例如砷铜的精炼与熔炼。有限的锡加工相关证据则显示，当时的生产活动以回收利用锡青铜废金属为核心方向。
