陕西杨家湾出土西汉彩绘兵马俑的修复保护研究

陕西咸阳杨家湾出土的西汉彩绘兵马俑出现大面积严重风化褪色现象及彩绘层严重脱落、起翘,应尽快采取抢救性保护措施对其进行保护。在系统分析了该批彩绘兵马俑的病害种类及其产生原因后,通过XRD、SEM—EDS和Micro FT-IR对其彩绘颜料成分进行了分析。此基础上,制定了一个系统的修复方案,选取了合适的修复工艺及修复保护剂。结果表明,三乙氧基硅烷缩合而成的树脂胶材料对彩绘层进行回帖后,其强度有了明显的增强。经过自行研制的RFC显现加固剂处理后的彩绘颜色显现出了其古朴清晰的原貌,且颜料附着力增强。

杏花文化的侧装双鋬手陶鬲

侧装双手陶鬲是龙山时代分布于太行山脉两侧的杏花文化最具特征的标识性器物。据侧装双手陶鬲的形态变异及其层位关系,可排出其形态的演变序列。侧装双手陶鬲的制作工艺也相应地基本上经历了两个相继发展的阶段:前一阶段是受陶影响而产生的“式鬲”,由分制的鬲足和鬲身整合成全器,因鬲足的接法不同而形成宽弧裆和平裆;后一阶段才是真正意义的鬲,即抛弃鬲身靠鬲足的联接形成全器主体,并形成尖角裆。此型鬲工艺演变表明:工艺革命只是工艺演进的量的积累到一定程度出现的质变。它虽是变革传统,但它的发展速度、方向,又受传统以及传统中的矛盾逻辑地向前展现的轨迹或定式所影响乃至制约。没有革新与革命,就不能打破传统,然而传统确是伴随革新或革命的影子。这在纯粹的工艺中,则仅是惯性或为惰性思维,但工艺却是社会中的工艺,则又不能不涉及社会中不同人们的不同观念乃至利害矛盾以至冲突,甚至激起一部分人站出来捍卫祖法、保持传统的说教与斗争。这种陶鬲的排序,分别适用于岔沟、双务都、乔家沟和游邀、临水与杏花村诸遗址的杏花文化分期或文化阶段划分。这种陶鬲的谱系研究表明,杏花文化是一自具特征、演变清晰、源流有自,并对其周边地区产生了重要文化影响和起了重要作用的考古学文化。

Technological features of Apulian red figured pottery

Apulian red figured pottery samples, dating back to the 5th and 4th centuries BC, from the archaeological site of Monte Sannace (Gioia del Colle, Bari, Italy) have been characterized from the physical–chemical, mineralogical and morphological points of view. Scanning electron microscopy, X-ray diffraction and atomic spectroscopy investigations have been carried out on the ceramic body, red decorated area and black gloss of the fragments, with the aim of outlining the technological features and of defining the nature of coatings and decorations. All 5th century fragments show the same features: fine texture of the ceramic body, red figures saved from the ceramic paste and black gloss painted directly on the ceramic body. The statistical treatment of compositional data of ceramic bodies excludes the local production of these objects. As regards the 4th century fragments, some show similar features to the 5th century ones; however others are characterized by the coarse texture of their ceramic body and an intermediate red layer of finer clay between the black gloss and the ceramic body. The analytical results make it possible to distinguish two different production technologies of red figured Apulian vases in Monte Sannace during the 4th century BC. Certain vases were produced using the “classic” Attic technology and others with a different technique, not previously known, which involved the application of a red engobe layer on the clay paste, before the black gloss painting.     

Characterization of Iron age pottery from eastern Turkey by laser- induced breakdown spectroscopy (LIBS)

Selected pottery sherds coming from the Ayanis, Dilkaya and Karagündüz excavations in eastern Turkey and dated from the Early to Middle Iron Age were examined as regards their composition by using laser-induced breakdown spectroscopy (LIBS). The objective of the study was first to investigate the potential of the LIBS technique in the compositional analysis of pottery and further to explore correlations in spectral data, by using chemometrics methods that would possibly enable discrimination among different sherds. This work is part of a broader study aiming to examine clay variability both before and during the Urartian State period and to explore possible relationships and differences among pottery objects from fortresses and settlements or settlements and cemeteries on the basis of the clay composition of sherds. Preliminary results demonstrate that by using the LIBS technique it is possible to analyse pottery sherds in qualitative and semi-quantitative ways, providing information on the clay and slip composition. Furthermore, encouraging results have been obtained by carrying out principal component analysis (PCA) on the LIBS spectra, which suggest that in certain cases, it is possible to directly correlate spectral information with the origin of pottery sherds.
