中国古代石窟壁画制作工艺研究

壁画是人类历史上最早的绘画形式之一,即绘在壁上的画。原始社会时期,人类在洞壁上刻画各种图形以记事,便形成了最早的壁画。按其表现形式,壁画可分为宫廷壁画、墓葬壁画、古建壁画、石窟壁画等,其中石窟壁画以表达宗教内容为主。本文采用光学显微镜、拉曼光谱和扫描电镜对多个地区的石窟壁画样品进行了分析和研究,分析结果显示采用的颜料包括无机矿物颜料和现代颜料,地仗层主要使用石膏、石灰、泥层等,使用的胶结材料为动物胶中的皮胶、骨胶和植物胶中的桃胶。     

利用FT-IR、Py-GC/MS和THM-Py-GC/MS微损分析技术探索油画文物复杂的有机基质组成

近现代油画有机基质组分复杂、难辨,其分析鉴定是当今文物保护科技研究的难点之一。利用微损分析技术研究油画文物复杂的基质结构、材料和技法,可以阐明油画特定层的性质和状况,对于专业保护人员制定修复决策至关重要——这对选择正确修复技术非常有用,关系到修复后油画的安全状态,因此已成为许多研究者关注的焦点。本研究利用傅里叶变换红外光谱(FT-IR)、热裂解气相色谱-质谱(Py-GC/MS)和热辅助水解甲基化-裂解气相色谱-质谱(THM-Py-GC/MS)等微损分析技术对一幅中国国家博物馆藏油画《德涅泊尔河的秋天》进行科技分析。研究发现,综合运用这些微损分析技术可以有效识别油画用的胶结介质和其中添加剂的种类,最大限度、准确、完整地提取样品中所蕴含的信息。结果表明,该油画的有机胶结材料为聚乙烯醋酸酯类材料和亚麻籽油,同时聚乙烯醋酸酯类材料中使用了邻苯二甲酸二丁酯作为增塑剂。裂解产物中不含光油树脂类成分,说明画作下部的光亮层并非作者有意上的光油层。此外,油画部分区域还添加了蜂蜡作为改性材料,起到增加颜料稠度、可塑性和减弱光泽的作用。     

故宫东华门城楼天花颜料胶结材料的科学研究

为研究故宫东华门城楼井口天花所用颜料胶结材料,通过热裂解-气相色谱/质谱联用仪(Py-GC/MS)、红外衰减全反射(ATR)面扫描对东华门绢本、纸本天花绿色颜料层分别进行分析检测。PyGC/MS分析表明绢本天花绿色颜料层所用胶结材料应为动物胶,且天花上有油脂类污染物;红外ATR面扫描分析确定纸本天花绿色颜料层所用胶结材料为蛋白质类材料,且可能为动物胶。研究结果有助于故宫东华门城楼井口天花制作工艺的研究及保护方案的制订。

传统水硬性灰浆性能的影响因素综述

水硬性灰浆是性能优良的传统建筑材料,其相比于气硬性灰浆,有更好的防水性、透气性、耐冻性、耐盐结晶性和机械强度等,适合作为古建筑的修复材料。本研究对影响传统水硬性灰浆性能的因素进行归纳综述,探讨无机物(胶凝材料、骨料、水)、天然有机物(多糖类、蛋白质类、油脂类)、养护条件等对水硬性灰浆性能的影响。其中,无机物对水硬性灰浆的性能影响一方面取决于胶凝材料的特性,另一方面取决于灰浆中不同无机组分间的比例;在水硬性灰浆中加入多糖类有机物可提高灰浆力学性能,加入蛋白质类有机物可提高防水性和孔隙率,加入油脂类有机物可大幅提升防水性、耐久性;在高相对湿度条件下养护水硬性灰浆可提高其机械强度,而低湿度条件下养护的灰浆则更具耐久性。本研究成果可为认知、揭示传统水硬性灰浆的科学价值,研究、开发新型古建保护修复材料提供参考与启示。     

纸质文物的热裂解气相色谱-质谱应用研究

对纸质文物的科学认知是保护这类珍贵文化遗产的关键。本研究将热裂解气相色谱-质谱(Py-GC/MS)技术应用到中国传统的四类典型手工纸(竹纸、麻纸、桑皮纸和构皮纸)的分析中,结果表明竹纸中苯酚类物质含量较高,桑皮纸和构皮纸中含有大分子三萜类特征物(如β-香树脂醇、α-香树脂醇和豆甾-3,5-二烯等物质),而麻纸中则无此类特征物——利用这些特征化合物可以区分竹纸、麻纸和桑皮/构皮纸。将这一成果应用到一副清代蜡笺纸对联的分析中：确定了该书法用纸为皮纸(桑皮纸或构皮纸);检测出长链脂肪酸和醇类物质,表明蜡笺纸的制作使用了蜂蜡;检测出吡咯及其衍生物,表明该书法蜡笺纸装裱时所用的胶结材料为动物胶;另外检测到了生物碱类物质,表明该蜡笺纸使用了植物染料。综合以上研究表明,Py-GC/MS方法不仅能够确定中国传统纸质文物的纤维来源,同时可以确定纸质文物上蜡、胶结物及染料等信息;结合传统的赫兹伯格(Herzberg)染色法,进一步确定了皮纸的具体种类。蜡笺纸文物材料信息的检测识别可为文物保护与修复工作提供科学依据,此研究方法为纸质文物的科学认知提供新思路。

Examination of some pigments,grounds and media from Egyptian cartonnage fragments in the Petrie Museum,University College London

A number of cartonnage fragments from the collections of the Petrie Museum, UCL, were examined to identify pigments, media and grounds. The different types of cartonnage made in ancient Egypt are reviewed. Special attention was paid to green pigments, which were shown to be of green earth, or a mixture of Egyptian blue and a yellow, usually goethite or orpiment. Green earth was found in one artefact, dated to the 9th century BC: all other examples were from the Graeco-Roman period. No copper-organometallic greens were present in the examples studied, or Egyptian green, or malachite. Binding media was identified both by ELISA and by GC/MS. A pink colourant was identified as madder, while lead white was used as a white in one example, showing the influence of Roman and Greek pigments on Egyptian art in these later periods. Plant gum, egg, and animal glue were found in different fragments, with mixed media in a few cases. Moganite was found associated with quartz in some preparatory layers by X-ray diffraction, which has not been reported previously as a constituent of ground layers in Egyptian artefacts.

Characterization of organic media in the wall-paintings of the “Palace of Nestor” at Pylos,Greece: evidence for a secco painting techniques in the Bronze Age

This paper presents the results of an investigation of organic binding media detected in samples from the Mycenaean wall-paintings at the “Palace of Nestor” in Pylos (Western Messenia, Greece): samples dated from the Late Bronze Age (ca. 1200 BC). This is the first scientific study to be conducted on organic binding media in Mycenanean painting, and it is a study that aims to contribute significantly towards our understanding of the original painting techniques used during the Bronze Age. The analytical procedures employed for the detection and characterization of the organic substances preserved within the paint layers (proteinaceous materials, lipids and plant gums), were based on chromatography/mass spectrometry techniques (PY–GC/MS, GC/MS). The most significant results, highlighting an a secco painting technique, are herein reported and discussed.

Application of tin to ancient pottery

It has earlier been assumed that the tin cover found on certain antique vases has been attached as a thin foil. In this paper it is shown that the metal may simply have been applied by an immersion technique. Before dipping into the tin melt the pottery must be treated with an adhesion promotor. Animal glue which was known as a binder in ancient times has been found to be useful for the surface treatment.

Scientific investigation of the paint and adhesive materials used in the Western Han dynasty polychromy terracotta army,Qingzhou, China

A royal tomb of early period of the Western Han dynasty (206 B.C–8 A.D) was excavated by archaeologists in Qingzhou County, Shandong Province in 2006. Over 2000 polychromy terracotta soldiers, horses, chariots, servants etc. were unearthed from the tomb. All the terracotta figures are one quarter or one sixth as large as the livings, most of them were painted with well designed patterns. In order to gain complete information about the materials and techniques used for the polychromy on the terracotta army, five samples from the painted areas were taken. In addition, one sample from the area to adhere one leg to the ploychromy horse body was also obtained. The analytical techniques applied include XRF, FTIR, Py-GC/MS and GC/MS. Chinese purple, cinnabar, lead red and ochre were used as pigments, while animal glue was identified as binding medium and adhesive in the polychromy terracotta army in the Han Dynasty. The results definitely will provide new evidence about the materials and technologies used in Han Dynasty. Especially, the binding medium identified is different in comparison with Qin Shihuang's terracotta army (259–210 BC).     

From Byzantine to post-Byzantine art: the painting technique of St Stephen's wall paintings at Meteora,Greece

The old katholikon of St Stephen's monastery at the Meteora (site of the most important complex of monasteries in Greece after Mount Athos) is decorated with wall paintings that date from the beginning of 17th century. In terms of style, the artistic ensemble is altogether characteristic of the period. The painting technique has been examined by means of μRaman and μFTIR spectroscopies, gas chromatography–mass spectroscopy (GC/MS), optical microscopy (OM) and scanning electron microscopy (SEM).     

Neolithic Adhesive from a T‐shaped Ornamental Element Excavated at Site 14 at Kowal,Kuyavia, Central Poland

We conducted an identification of a substance isolated from a T‐shaped ornamental element excavated from a Globular Amphora Culture tomb at the Kowal 14 archaeological site in Poland. ¹⁴C dating indicated 4105 ± 35 bp (POZ‐21912) and 3990 ± 50 bp (POZ‐21910). Analytical methods such as SEM–EDS, XRD and FT–IR were applied to study the origin of its structure. The results of instrumental analysis and the archaeological context indicate that the adhesive substance investigated consists mainly of calcium carbonate (calcite, 78–88%), silica dioxide (quartz), sodium aluminium silicate (albite) and potassium aluminium silicate (microcline). The material might be a man‐made, mineral adhesive, a kind of lime mortar. The object is considered as the oldest European finding of this type outside the Mediterranean Basin. It provides evidence for the use of the lime calcination process in Central Europe as early as in the Late Neolithic, for which there were—up to now—no convincing premises.     

殷人尊东北方位说补证

殷人有重视东北方位、把东北看作是吉向尊位的传统观念。这是由于商族起源于东北地区的古渤海湾一带。甲骨文中“东北”为尊位而“西南”为卑位。商代都城规划中重东北方位的经营,如郑州商城、偃师商城、黄陂盘龙城、夏县东下冯商城、新近发现的焦作府城商代城址和洹北商城等莫不如此。尤以殷墟都城的规划布局重东北方位为甚,如殷墟地区时代最早的遗址在殷墟都城的东北部;殷墟都城之宫城正位于整个都城范围的东北部;殷墟发现的车马坑与大墓的位置关系也表明尊东北方位,等等。
