The foral charter attributed by D. Manuel I of Portugal, in 1514, to the village of Sintra was studied using Energy Dispersive X-ray Fluorescence spectrometry, Raman and Infrared micro-spectroscopies. A complete characterization of the pictorial materials used in the production of this masterpiece allowed the identification of iron gall inks used in the written text; pigments such as malachite, azurite, lead white, cinnabar, yellow ochre, gold, silver and carbon black in the illuminations and letterings; filler and binder used in the production of coloring materials and inks. Gum and calcium carbonate were the most recurrent binder and filler identified in this study. Silvering and gilding were mostly obtained by applying ground silver and gold on parchment.
葡萄牙国王曼努埃尔一世于 1514 年授予辛特拉村的宪章采用能量色散 X 射线荧光光谱法、拉曼和红外微光谱进行了研究。对这幅杰作制作过程中使用的绘画材料进行了全面的表征，鉴定出了用于书写文本的铁胆墨水；在插图和字母中使用了孔雀石、蓝铜矿、铅白、朱砂、黄赭石、金、银和炭黑等颜料；在颜料和墨水的制作中使用了填充料和粘合剂。在这项研究中，最常识别出的粘合剂和填充料是明胶和碳酸钙。上银和镀金主要是通过在羊皮纸上涂磨碎的银和金来实现的。
