Scythian Burial Mound of the 4th Century Bc at Kremenevka,Northeastern Azov Region

The article describes and analyses a burial complex dated to the 4th century BC and located near the village of Kremenevka (Donetsk Province, Ukraine) in the northeastern Azov region. Types of amphoras are identified and the burial complex is more accurately dated to the third quarter of the 4th century BC. A funeral rite unique to the steppes of the Northern Pontic region is reconstructed and described on the basis of stratigraphic data.     

Chemical and lead isotope analysis of some lead-barium glass wares from the Warring States Period,unearthed from Chu tombs in Changde City,Hunan Province,China

In the context of the present study, we have conducted chemical and lead isotope analyses on twelve ancient glass samples unearthed from Chu tombs in Changde City, Hunan Province. The results of the chemical analysis of these samples show that all samples are PbO–BaO–SiO₂ glasses, thus indicating that they are all traditional ancient Chinese glasses. The chemical results also suggest that all Bi wares may either share a common source or were produced according to similar recipes. In turn, the eye beads are different from the Bi wares for their distinct chemical composition. The chemical results indicate that silica, lead-bearing material, barium-bearing material, and sodium/lime-bearing material are the main independent components of the raw materials employed in the production of these glass wares.     

Supply routes and the consumption of glass in first millennium CE Butrint (Albania)

Archaeological, historical and analytical evidence can identify trade patterns and the movement of people and products and thus reveal the cultural and economic connections that existed at a given time. In the case of first millennium CE glass, the manufacture of raw glass in a limited number of glass making installations with unique compositional characteristics makes it possible to trace the likely origin of the raw materials at consumption sites. In this way the analytical characterisation of a large corpus of glass finds can identify changes in the supply routes of high-end industrial products from the Roman to the middle Byzantine period.     

A cost surface model of volcanic glass quarrying and exchange in Hawai‘i

The spatial distribution of artifacts from the Pu‘u Wa‘awa‘a volcanic glass source (North Kona District, Hawai‘i Island) shows a pattern of direct access by those living in the immediately vicinity of the source with subsequent down-the-line exchange. Most quarrying and exchanges likely occurred within a single day’s travel from sites where artifacts were deposited. The exception to this is the discovery of non-local direct access evident in assemblages from the extreme southern end of Hawai‘i Island; these visits may have involved voyages by canoe. While people did not often travel far for volcanic glass they nonetheless appear to have had unfettered accessed to source material and freely conducted inter-community exchanges. This implies volcanic glass was treated as a common pooled resource and the existence of informal exchange relationships.     

青铜文物研究中CT成像的几个作用

通过计算机断层扫描(CT)检测与成像分析后发现:陈璋圆壶的组成构件有26个,而非最初考古报告表述的19个,分三个部分合成;吴王僚剑的剑体腐蚀严重,剑上铭文为铸造而并非后刻;春秋青铜盘修复前的状态清晰可见。由此说明,CT技术在研究古代青铜器铸造工艺、鉴定青铜器真伪、检验保护修复技术路线等三个方面能起到关键作用。     

一件中国国家博物馆馆藏铜雕塑锈蚀产物的分析研究

铜雕塑作为现代艺术品因其历史价值、文化价值、审美价值、科技价值和时代价值被越来越多的博物馆收藏。经过岁月的洗礼,雕塑上有时也会出现锈蚀产物,锈蚀产物或影响艺术品的美感或进一步损害雕塑,因此需要对锈蚀产物进行鉴别,然后采取适合的方法将其去除。为此,通过超景深三维视频显微观察、扫描电子显微镜-能谱仪、显微激光拉曼光谱和傅立叶变换显微红外光谱对一件中国国家博物馆馆藏铜雕塑锈蚀产物进行取样分析。能谱结果表明该锈蚀产物中没有氯离子,再结合拉曼光谱和显微红外光谱结果可以确定锈蚀产物是蓝铜钠石[Na₂Cu(CO₃)₂·3H₂O]和含有钠离子和氧离子的水合甲酸铜[Cu₄Na₄O(HCOO)₈(OH)₂·4H₂O],这种铜锈蚀产物在国内报道较少。为防止它们进一步腐蚀和损害雕塑,选择使用物理方法将锈蚀产物清除。科学的检测方法和分析手段为铜雕塑保护方案的制定提供了重要信息支撑和理论依据。     

Sasanian glass from Veh Ardašīr investigated by strontium and neodymium isotopic analysis

A collection of 31 glass fragments, dated to the 3rd to 7th century AD and excavated in Veh Ardašīr, (modern Iraq), were analysed for their Sr and Nd isotopic compositions with the aim of deepening our knowledge on glass circulating within central Mesopotamia during Sasanian times and to highlight the merits of isotope ratios for the definition of the production scenery. Based on the elemental composition of the samples, two groups related to the exploitation of different plant ashes were previously distinguished, and also a change in the silica source in the course of the 4th century AD emerged. The determination of isotopic distributions of Sr and Nd offers a deeper insight. The ⁸⁷Sr/⁸⁶Sr isotope ratio, together with the Sr elemental concentration, confirms this use of different plant ashes, and permits one to distinguish distinct glass batches, although the isotopic Sr signature does not allow us to highlight evidences of different provenances for the samples of different composition. Moreover, the ¹⁴³Nd/¹⁴⁴Nd isotope ratio suggests the use of sands belonging to a common geological area, and also allows the identification of a set of samples that were possibly produced exploiting a further different sand source. As a whole, Sr and Nd isotope ratio values for the samples considered, i.e. ⁸⁷Sr/⁸⁶Sr = 0.70833 to 0.70916 and ?Nd = −8.69 to −4.98, differ from the published isotopic data on middle Eastern glass samples and can therefore define a characteristic Sr–Nd signature for plant-ash Sasanian glass excavated in Veh Ardašīr.     

Glass from the Archaeological Museum of Adria (North-East Italy): new insights into Early Roman production technologies

In the present study, the first archaeometric data on an ample selection of intentionally coloured (or decoloured) Early Roman glass (1st–2nd centuries AD) from the Archaeological Museum of Adria (Rovigo, Italy) are reported. The analysed samples are 61 in total, both transparent and opaque, and were characterised from the textural (SEM-EDS), mineralogical (XRPD) and chemical (XRF, EPMA, LA-ICP-MS) points of view. This combined approach allowed us to identify the raw materials and production technologies employed in the manufacture of glassware. Results for the transparent samples show that they are all silica-soda-lime glasses. Most of them, independently of colour, have compositions close to those of typical Roman glass, produced with natron as flux. No relationships were identified among chemical compositions, types or production techniques, but a dependence on bulk composition was identified for some particular colours, revealing the careful and intentional selection of raw materials. This is the case of Sb-colourless glass, produced with sand of high purity, a group of intensely coloured objects, mainly emerald green and black, produced with soda ash as flux, and some blue examples produced with various sources of sand or soda ash as flux. Two main types of opacifiers were identified for the opaque samples: calcium antimonate for white, mauve and blue glasses, and lead antimonate for the yellow ones; in one case, a yellow lead-tin antimonate was also identified. As regards the opaque glasses, most of the samples opacified with calcium antimonate are silica-soda-lime in composition, similar to the typical Roman glass. Instead, samples opacified with lead and/or lead-tin antimonates are lead glasses, suggesting different production technologies.     

Humerus Varus in a Subadult Skeleton from the Medieval Graveyard of La Madeleine (Orléans,France)

The skeleton of a subadult individual from the medieval graveyard of La Madeleine (Orléans, France) exhibits varus deformity of its right humerus. The affected bone is shortened, the diaphysis is angulated and the head is grossly deformed. The skeleton is otherwise normal. Several diagnoses are debated, including mucopolysaccharidoses, thalassemia, infection and trauma, the latter being preferred. The severity of the bone changes suggests that the growth disturbance occurred early in the life of the individual. We therefore suppose that the causative trauma occurred at the time of birth or during the early postnatal period. Copyright © 2011 John Wiley & Sons, Ltd.     

A Late 17th‐Century Trade Cargo from Ponta do Leme Velho,Sal Island,Cape Verde

In 1973, while recovering copper cargo from a 20th‐century ship wrecked off the Ponta do Leme Velho on the south‐east side of Sal Island, Cape Verde, explosives revealed an earlier ship cargo with dozens of Portuguese faience plates and bowls, glass beads and metal objects, including buckles, ammunition and copper manillas. The assemblage, including the ceramics and a marked silver tastevin, provide a site date between 1680 and 1700. The research presented here is a result of collaboration between CPAS and the authors in 2008 to analyse this assemblage in the context of late 17th‐century maritime trade.
