The Santa María pottery of El Bolsón valley (Catamarca,Argentina): Compositional characterization and implications on the elaboration processes,ca. 1000–1600 ce

The results obtained from the multi-analytic compositional characterization of ceramic pastes and paints of the Santa María style, from the El Bolsón valley (Belén Department, Catamarca Province, Argentina), are presented here. This pottery style had a wide regional distribution in Northwestern Argentina between ca. 1000 and1600 ce and is characterized by its complex iconography painted in black, cream and red. The analyses show that the containers correspond to the technical tradition of using grog temper and suggest that its manufacture involved a double firing process. This reveals a new practice for the time.     

汉代复色低温铅釉陶器初探

复色釉陶是汉代低温铅釉陶中的一个特殊品种,其施釉烧制工艺系在普通单色釉陶的基础上,于一件器物上施加两种及以上釉料,以低温一次入窑烧制而成,呈现出绚丽的艺术效果,达到了汉代釉陶的高峰。此类釉陶主要分布于宝鸡、济源和延安及其周边地区;最早出现于西汉中晚期,流行于西汉晚期至东汉初期。就施釉工艺而言,其多色施釉技术与北魏时期的二色釉陶一脉相承,并在北齐时期与新出现的"瓷胎铅釉陶"二次烧制技术相结合,形成了北齐特有的多色瓷胎铅釉陶器,为后来唐三彩的出现奠定了技术基础。     

明初大运河南旺分水枢纽水工技术考

明朝初年,国脉皆仰东南,为解决南方粮财物的北运问题,宋礼和白英受命组织修建了大运河山东段南旺分水枢纽。该枢纽主要包括引汶济运、导泉补源、设立水柜和置闸节流四个组成部分。其中,引汶济运是工程之重点,包括戴村坝、小汶河、南旺分水以及配套工程等四个子系统。这些水利设施组成一个和谐的系统工程,保证了该段运河的水量稳定充足,从而实现了大运河500余年的正常通行。南旺分水枢纽代表了我国古代运河水工的最高科学技术成就,堪称世界水利史上的一大经典范例。     

安徽巢湖放王岗出土西汉漆器漆膜测试分析

为了解放王岗出土漆器的髹漆技术,采用了漆膜切片技术、X射线衍射粉末法、傅立叶红外光谱法和显微镜等分析方法对漆器残片进行了分析。实验结果表明:大部分的漆膜包含1～3层髹漆层,一些漆膜中存在着漆灰层;采用了HgS作为漆膜的红色呈色颜料;可能采用了混合大漆和其它有机物的漆料;特别是漆膜中发现了含量约在5%左右的石英颗粒,其成因和作用值得现代漆器业去研究。     

‘Rid grasse of bones’: A taphonomic study of the bones from midden deposits at the Neolithic and Bronze age site of Runnymede,Surrey, England

Runnymede has large samples of Neolithic and Late Bronze Age animal bones, with contrasting preservation conditions in both periods. The bone evidence has been used to interpret the formation of the site deposits. There are few articulated bones, and no joins were found in butchered bone, indicating that the area studied did not contain primary refuse. Various aspects of bone alteration have been analysed: (i) the proportion of bones with very good surface preservation was high in the in situ Neolithic excavation units and the basal Bronze Age midden, but bones in the upper units were mostly eroded. These units are reworked flood deposits. The greater degree of fragmentation of the bone in the reworked units has been quantified, using a system of recording the ‘zones’ present on each bone, which allows calculation of the fraction present. It is also demonstrated that the reworked units contain a lower proportion of identified bones and a higher proportion of teeth and iaws than the units with well-preserved bone, (ii) Quantification of canid gnawing shows, unexpectedly, that more was recorded on well-preserved bone. Thus recognition of gnawing depends on bone condition. This also confirms that most of the erosion of the bone surface is a post-depositional phenomenon. The sequence of activities is therefore interpreted as follows: meat was cooked and consumed, and the bones discarded for the dogs. At a later stage, larger bones were picked up and thrown away in the river or midden. Some ethnographic examples of periodic cleaning of farming settlements are cited.     

A New Methodology and Classification System for Describing Three‐Dimensional Particle Formats: Application to Clastic Lithic Products of Archaeological and Geological Origin

A new classification system is proposed to describe the volumetric formats of clastic lithic products of geological and archaeological origin. In order to build this operative classification, the rectangular block or cuboid is established as the standard geometric format to represent their three‐dimensional format (the X‐axis being length or long diameter, the Y‐axis being the width or intermediate diameter, and the Z‐axis being the thickness or short diameter) on a two‐dimensional diagram. To obtain this graph, each absolute coordinate (X, Y, Z) defining the prisms is projected on to an auxiliary plane with a new set of relative coordinates (x, y, z), expressed as the percentage of their sum. The projection generates a triangular diagram on which the indices of elongation and flatness are represented. A geometric transformation converting the triangular diagram into a quadrangular diagram has been produced in order to better represent the scatter points. Then, a double scale is necessary: (i) an absolute scale to quantify the indices, and (ii) a relative scale to calculate where the graphic locus is projected. This new graph also allows us to work with statistical parameters. Finally, two classic examples of applications selected from the literature are shown.     

商前期青铜斝铸造工艺分析与模拟实验研究

斝是一种酒器,夏代晚期已有出现,盛行于商到西周早期。关于斝的铸造工艺,前人也曾做过一些相关研究。我们通过对出土斝范的考古调研、对铜斝的实物考察和对其铸造工艺的模拟实验研究．认为黄冈博物馆所藏商前期铜斝是采用典型的三分法制作的。斝腹部凸起的棱角分明的兽面纹和柱帽上的涡纹,是在范面上制作出来的;斝腹芯和鏊芯是由芯盒制作而成;铸型不糊草拌泥也可单独阴干、焙烧并用于浇铸。     

商前期青铜斝的制模工艺初步研究

制模是青铜铸造工艺的第一道工序,也是关键工艺之一,其重要性不言而喻。而文献记载的缺乏,考古实物资料的限制,严重影响了学界对陶模制作工艺的认识。近年来,我们通过对大量青铜实物的细致考察,发现大多青铜器上都有明确、整齐的范缝。为研究夏商之际的范铸技术,我们对商前期青铜斝进行了模拟制备,发现分型制模才是其制模工艺的主流,用此种工艺制模更加符合器物上的范铸特征。     

Frogs as a part of the Eneolithic diet. Archaeozoological records from the Czech Republic (Kutná Hora-Denemark site, Řivnáč Culture)

Within the site of Kutná Hora-Denemark (Kutná Hora distr., central Bohemia – Eneolithic, ?ivná? Culture, 3000–2800 BC), 893 frog bones or bone fragments were present in five archaeological features. All identified specimens are of the Common Frog (Rana temporaria Linnaeus, 1758). Males predominate, according to humeral morphology, and only adult individuals are present. The most important findings come from feature 36, where an accumulation of 739 frog bones (MNI = 123) were found, of which 10% (NISP) were burned. This and other contextual evidence indicates that they relate to activity of the Eneolithic people in the settlement. The predominance of hind leg bones and other circumstantial evidence suggest that the frogs were part of the human diet. Behavioural studies of this species suggest that the frogs were gathered from small ponds during the months of March or April. Similar findings are rare.
