Abstract Four glass beads from a Scythian burial on the island of Khortytsia (Southern Ukraine) were subjected to 3D imaging using micro-CT and photogrammetry. The aim was to reconstruct the process used to produce and decorate the beads by detecting and interpreting the traces left by the technological processes on the bead surface and in the glass body. It turned out that all the beads were obtained by winding hot glass around the mandrel. The distribution, size and shape of the bubbles in the glass matrix revealed by the micro-CT scans and the features observed during a thorough examination of the photogrammetric models allowed us to follow the movements of the bead maker during the formation of the bead body and its decoration, highlighting several details of the production processes such as the number of the superimposed layers and the direction of the rotation of the mandrel during both the formation of the body and the decoration of the bead. Some information about the tools also emerged, with particular reference to the shape of the mandrel, the possible use of a releasing agent and how tools were used to decorate the surface or to remove the beads from the mandrel. According to the archaeological classification, the beads considered here belong to three different types, that are considered chronological indicators of the fourth century BCE and are found in archaeological sites spread over an area extending for several thousand kilometers from the Black Sea coast to the Ural Mountains. This work enriches the knowledge of the micromorphology of beads found in Eastern Europe, which is rarely discussed in the scientific literature on the archaeological glass beads.

Abstract What are Cy Twombly’s sculptures made of? This article presents an overview of a non-destructive examination conducted on three sculptures by American artist Cy Twombly (1928–2011) as part of an art-technological research project at the Doerner Institut in Munich. The artworks are part of the collection of the Brandhorst Museum and belong to Twombly’s series of so-called ‘Original Sculptures’: assemblages of individual found objects, which the artist covered and modified with layers of plaster and white paint. To develop a long-term preservation strategy, the research focused on understanding the materials and construction methods used in Twombly's sculptures. In collaboration with the Chair of Non-Destructive Testing at the Technical University of Munich, the artworks were inspected using X-ray radiography and computed tomography. The results showed that Cy Twombly used various everyday objects made from wood, plastics, metal, and paper/cardboard to build the assemblages. Unexpectedly, the examinations revealed that the individual parts are solely held together by the coating of plaster and paint, lacking additional mechanical connections. The overall structure thus proved to be very fragile and highly sensitive to physical stresses, whether due to handling, transport, or strains in the microstructure caused by climatic fluctuations. Since little was known about Cy Twombly´s choice of materials and manufacturing details, the results offer valuable insights into the overall artistic process and decision-making of one of the most influential artists of the 20th/twenty-first centuries. Conservators can use the art-technological findings to monitor the sculptures ‘condition and develop or adapt long-term preservation strategies, including aspects such as ambient climatic conditions and handling storage and transport specifications. In addition, the knowledge generated can be used for further research on the specific materials and transferred to other artworks by Cy Twombly.

Abstract ‘Fingerprint’ identification is the key to turquoise provenance studies, but previous studies have met with limited success in China. Turquoises in China mainly occur in altered sedimentary rocks and are formed by weathering, leaching and sedimentation. This paper evaluates the potential for sedimentary environment sensitive elements to be used to distinguish between turquoise deposits in China. In this paper, the ratios of V/Mo, Ce/Ce*, Ni/Co, Sr/Ba, Tl/Ga, Li/Ba and V/Cr were calculated for turquoise of different origins. Our results show that these parameters when used alongside Ga concentration permit effective discrimination between turquoise sources in China. This approach brings to light a new means of analyzing trace element databases and an untapped wealth of information that can be used for future turquoise provenance studies.

Abstract Oral history indicates that a large wooden trough held in storage at the University of Kentucky’s William S. Webb Museum of Anthropology was a component of the saltpeter mining operation in Mammoth Cave in the late 18th and early 19th centuries, worked largely by enslaved persons. We used multiple heritage science methods, including radiocarbon wiggle-match dating, tree-ring dating, scanning electron microscopy-energy dispersive X-ray spectroscopy (SEM–EDS), and optical scanning, combined with historical research, to examine the trough. Our analysis supports the oral history of the trough as an artifact of the mining system in Mammoth Cave. This case study illustrates how heritage science methods can provide corroboration for the origins and biographies of poorly documented historical artifacts.

Abstract The gradual loss of certain good cultural genes in the traditional ritual system is, to some extent, driven by the value orientation of the art of ancestral hall decoration. This article uses wall paintings as a medium to uncover significant variables affecting the decorating of ancestral hall murals and to analyze the culturally formative relationships underlying their art from a ceremonial perspective. It depends on textual excavation. The analysis demonstrates that: (1) the 521 murals generally transmit positive content; (2) the shift in the painted figures’ seating and grooming from formal to casual represents the fading of ceremonial concepts; (3) The control of economic costs may be a possible explanation for the large number of figures in crouching, skirting, and side-lying postures in wall paintings; (4) The fact that the colors employed in the garments of the figures from the Ming and Qing dynasties don’t follow the folk color scheme demonstrates that the creative production at that time was not constrained by a lot of ritualistic considerations. The study concludes that the absence of an educational component in the arts is a contributing factor to the diluted nature of traditional rituals in modern China.

Abstract The fossils of Hamipterus tianshanensis (Wang et al. in Curr Biol 24:1323–1330, 2014) and their eggs have important scientific significance because they can provide unique information about the reproduction, development, and evolution of pterosaurs. The fossils and the rock surrounding them have, however, been weathered, which including powdering and flaking, since they were relocated from Xinjiang to Beijing. The high content of soluble salts is a significant factor in fossil deterioration because the dissolution–recrystallization process can generate tremendous pressure and lead to decreased mechanical strength. This study evaluated the electrokinetic desalination performance for the fossils, and two types of poultices employed including paper pulp from Bioline ® and CKS121 (cellulose: kaolin: sand = 1:2:1, w/w). Mercury intrusion porosimetry (MIP), scanning electron microscopy (SEM), ion chromatography (IC), and other methods were applied to evaluate the desalination effect. The surface salt content reduction by applied direct current (DC) was about 70%, and the inner salt content reduction was about 80%. The experimental results suggest that the electrokinetic method is a promising way to desalinate fossils. Nonetheless, cracks appeared in the surrounding rock crack after electrokinetic desalination, which can be explained by the montmorillonite swelling-induced stresses. Pre-consolidation, especially for electro-chemical method may solve the cracking problem for the clay-rich sandstone desalination.
摘要天山Hamipterus tianshanensis (Wang et al. in Curr Biol 24:1323-1330, 2014)化石及其卵为翼龙的繁殖、发育和进化提供了独特的信息，具有重要的科学意义。然而，这些化石和它们周围的岩石在从新疆搬到北京的过程中已经风化，包括粉末状和剥落。可溶性盐的高含量是导致化石变质的重要因素，因为溶解-再结晶过程会产生巨大的压力，导致机械强度下降。本研究评估了化石的电动脱盐性能，并使用了两种类型的膏剂，包括Bioline®纸浆和CKS121(纤维素:高岭土:沙子= 1:2:1,w/w)。采用汞侵入孔隙度法(MIP)、扫描电镜(SEM)、离子色谱法(IC)等方法对脱盐效果进行了评价。施加直流电流可使表面含盐量降低约70%，内部含盐量降低约80%。实验结果表明，电动力法是一种很有前途的化石脱盐方法。但在电动脱盐后，围岩裂缝中出现了裂缝，这可以用蒙脱土的膨胀诱发应力来解释。预固结特别是电化学预固结可以解决富粘土砂岩海水淡化的开裂问题。

Abstract The article describes the revolutionary new ways of communicating the written word when moving from the Medieval to Modern period in Europe, primarily the use of paper and moveable typeface printing and how these catalysed important cultural developments. A similar revolution has taken place in the last 50 years with the development of the internet. The article looks at how scientific publishing has changed with electronic publishing, including the development of Open Access. The journal Heritage Science is placed into this context. Especially important for scientific journals in an era when anyone can post anything on a webpage, is maintaining standards through high quality refereeing which distinguishes formal scientific literature from informal websites.

Abstract We have recently studied northern Finnish archaeological textiles extensively using computed tomography (CT) imaging. These textiles have been found in inhumation burials from the Late Medieval church of Valmarinniemi in Keminmaa and the Postmedieval church of Haukipudas. In this article we discuss the advantages and limitations of CT imaging based on three case studies. Based on the research objectives and the size of studied items, we utilised three different CT scanners: clinical systems and micro- and nano-scale X-ray microscopes. We were able to visualise a child’s coffin and a doll inside, which is a larger scale sample. We were also able to study and reconstruct the complicated structure of a tablet-woven band, as well as identifying individual fibres when examining smaller textile samples with submicron resolution. Even though we observed some limitations in the image quality, we conclude that computed tomography has great potential in the research of archaeological textiles in both 3D and cross-sections and is often easier and more informative than conventional microscopic or other archaeological methodologies.

Abstract The handheld X-ray fluorescence spectrometer (HH-XRF) is commonly used to detect the inorganic elemental composition of pigments on-site. However, the accuracy of in-situ detection results can be affected by the characteristics of the painted surface contaminants and the layered structure of pigments in ancient architectural color paintings. To mitigate this error, a method was proposed that combined the XRF spectra of inorganic pigments with the elemental concentration values obtained through principal component analysis (PCA). Additionally, this study discussed the typical surface contaminants and pigment layering found in color paintings separately. Firstly, experiments were conducted on dust accumulation layers of varying thicknesses. The results indicated that the condition of color paintings after pretreatment of dust accumulation tended to resemble the situation with thin dust accumulation during in-situ testing. A fitting formula was derived to establish a relationship between field testing and laboratory testing results. Secondly, experiments were conducted using various combinations of pigment layers. Based on the findings, it was hypothesized that there was a connection between XRF detection results and the maximum concentration value of a single element (as determined by XRF, in an unmixed or unlayered pigment sample without dust or smoke accumulation). The test results were fitted using a Polynomial formula, providing evidence for the existence of a nonlinear functional relationship between these two variables. Finally, an empirical formula for predicting the concentration values of the top color layer with different base colors was proposed. This study offered a precise method for accurately assessing pigments of ancient architectural color paintings through in-situ testing.

This study offered a precise method for accurately assessing pigments of ancient architectural color paintings through in-situ testing.","PeriodicalId":13109,"journal":{"name":"Heritage Science","volume":"44 2","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135215880","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"艺术学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Abstract There has been widespread concern about the provenance of proto-porcelain in previous studies, which is fundamental in determining the origin of porcelain. However, there are still different opinions on the provenance of proto-porcelain. To discuss this question, this study analyzed 21 proto-porcelain shards, excavated from the Yejiashan Cemetery, on the basis of typology, petrography, and LA-ICP-AES methodologies. Three shards from the Panlongcheng site were also collected for comparative analysis. The typological analysis showed that the majority of proto-porcelain samples from the Yejiashan Cemetery were similar to those from Northern China in type, shape, decoration,and glaze color, while 2 shards showed typical Southern characteristics. The petrographic analysis indicated that there were two different patterns of distribution for quartz particles in the collected samples, which suggested the potential existence of at least two different origins. The LA-ICP-AES analysis results also supported two different origins for Yejiashan proto-porcelain and suggested that one may originate from Zhejiang Province in Southern China. In summary, our study has demonstrated the existence of at least two distinct provenance areas for the proto-porcelain sourced from the Yejiashan cemetery. This distinction is founded upon disparities in typological characteristics, distribution patterns of quartz particles, and chemical compositions. This conclusion contributes to a better understanding of cultural exchange between the Zeng state and neighboring regions and can shed light on the manufacturing industry of the early Western Zhou Dynasty (1046–771 BC).
