Vessels made of chalk are common at Jewish sites throughout the southern Levant during the Roman period, apparently because stone was perceived to be impervious to ritual impurity. The study analyses samples from settlement and production sites to determine whether distinctive geochemical compositions might relate to specific source locations, and thus to provide the basis for conducting future large‐scale provenance studies. Distinctions between major elements, trace and rare‐earth elements as well as δ¹⁸O and δ¹³C isotopic compositions make it possible to discriminate between chalk sourced from Galilee and chalk from Judea.

来自黎凡特南部罗马时期生产和定居点的犹太白垩器遗骸的地球化学分析

在罗马时期，在黎凡特南部整个犹太地区，用粉笔制成的船只很常见，这显然是因为人们认为石头不能渗透仪式性杂质。这项研究分析了来自定居点和生产地点的样本，以确定独特的地球化学成分是否可能与特定的来源位置有关，从而为进行未来的大规模物源研究提供了基础。主要元素，微量元素和稀土类元素之间的区别以及δ ¹⁸ O和δ ¹³ Ç同位素组成使得有可能从粉笔加利利来源和白垩从犹太区分。
