Abstract

From a multidisciplinary perspective, we propose a first comparative study on the pigments of archeological pottery San José and Santa María of Yocavil valley, Province of Catamarca, Northwest Argentina (ca. S XI–XVI AD). Both stylistic sets share a color palette in which the black, red and cream tones are structured. Considering that we are handling objects of cultural heritage, an analysis strategy was developed that combines non-destructive techniques (XRFp and XRD) and minimally destructive sampling methods with other techniques (EDS and micro-Raman spectroscopy) for the characterization of elements and crystalline phases in pigments. The results show not only some shared features—as hematite in red paints and cream slips resulting from a low-iron clay base preparation—but also some diversity in the composition of the pigments—as presence of rutile in some red paints and pyrolusite or series of solid solutions in the system manganese–iron oxides in black pigments.

圣何塞和圣玛丽亚陶器（阿根廷西北约卡维尔谷）的滑画和绘画的成分研究：一种无损补充技术的方法

摘要

从多学科的角度，我们提出了对阿根廷西北部卡塔马卡省约卡维尔山谷的考古陶器圣何塞和圣玛丽亚颜料的首次比较研究。两种样式集共享一个调色板，在其中构成黑色，红色和奶油色调。考虑到我们正在处理文化遗产，开发了一种将非破坏性技术（XRFp和XRD）和最小破坏性采样方法与其他技术（EDS和显微拉曼光谱法）相结合的分析策略，用于元素和结晶相的表征在颜料中。
