ABSTRACT An interdisciplinary and multi-institutional group of science and art conservation specialists has provided new insight into the painting materials used in the polychrome walls and wooden ceilings in four seventeenth century Spanish colonial churches of Nueva Vizcaya (Chihuahua, Mexico). A multi-analytical study of the decorative surfaces was performed in situ using spectroscopic approaches (XRF, FORS), False Colour Infrared Reflectography – IRFC, as well as micro sampling for ATR-FTIR, LM and GC/MS laboratory analyses. A survey of natural resources were also studied by ATR-FTIR and LM to elucidate the natural occurrence of a select number of materials found in the surrounding areas of the churches. The present paper presents a multi-analytical study and characterization of green, red-orange and black colour pigments and binders selected from the decorative surfaces. The aim of this study is to highlight relationships between local materials and those from the original polychrome ceilings, in order to understand the material and technological influences that converged in the Spanish colonial architecture of northern Mexico.

在Nueva Vizcaya（墨西哥奇瓦瓦州）的西班牙宣教教堂中采用多种技术来表征彩色装饰表面

摘要一个跨学科和多机构的科学和艺术保护专家小组，为17世纪西班牙Nueva Vizcaya的四个殖民教堂（墨西哥奇瓦瓦州）的彩色壁画和木质天花板上使用的绘画材料提供了新见解。使用分光镜方法（XRF，FORS），伪彩色红外反射仪– IRFC以及ATR-FTIR，LM和GC / MS实验室分析的微量取样，对装饰表面进行了多分析研究。ATR-FTIR和LM还研究了自然资源调查，以阐明在教堂周围地区发现的一定数量材料的自然存在。本文提出了一种绿色的多分析研究和表征，从装饰表面中选择的橘红色和黑色颜料和粘合剂。这项研究的目的是强调当地材料与原始彩色天花板之间的关系，以便了解在墨西哥北部西班牙殖民建筑中融合的材料和技术影响。图形概要
