河北隆化鸽子洞元代窖藏织绣品蓝色染料分析

采用光学显微观察、激光拉曼、紫外-可见吸收光谱以及高效液相色谱对河北隆化鸽子洞蓝棉袄蓝色、浅蓝色纤维以及百衲枕顶蓝色纤维进行分析研究.通过多种分析手段相互佐证表明,该组样品采用蓝草中的靛蓝染色,色素成分有靛蓝素和靛玉红.各样品中色素成分比例均不相同,推测至少在元代,人类已经能够有意识地调整制靛工艺,染出自己需要的色光.同时靛蓝染料耐光性耐热性差,对酸、碱和氧化均敏感,耐盐性及耐细菌性较弱.在以靛蓝染色的织物清洗中,要选择性地使用洗涤剂,进行点滴试验后才可使用,同时在存放过程中要做到避光、避免高温.     

鲁北—胶东盐业考古调查记

本文通过对鲁北莱州湾和胶东半岛16个县市和出有盔形器的遗址进行了调查,对盔形器的形态演变、分布区域、使用功能等进行了初步研究,并与国内外有关遗址和类似器物作了比较分析,确认菜州湾沿海包含大量盔形器的遗址是商周时期的制盐作坊,而盔形器则是制盐的特殊用具.     

Temporal nature and recycling of Upper Paleolithic artifacts: the burned tools from the Molí del Salt site (Vimbodí i Poblet,northeastern Spain)

Recent research in Paleolithic archeology has stressed the importance of temporal issues in assemblage interpretation. Archeological assemblages are temporal constructs, formed by the addition of an unknown number of depositional events. This temporal dimension is also evident at the artifactual level, since single artifacts may undergo different events of modification and/or uses over time. The recycling of previously discarded blanks for tool production is one of the best examples of the temporal nature of artifacts. The aim of this paper is to evaluate the importance of recycling in a Late Upper Paleolithic site, examining a type of artifact – burned tools – that has up to now been little used to approach this issue. Our results suggest that recycling was probably a significant component of Upper Paleolithic provisioning behavior, with important implications in site formation processes and the typological variability of assemblages. The expedient or curated character of recycling is also discussed.     

遗址博物馆土遗址病害调查与成因分析——以萧山跨湖桥遗址博物馆为例

潮湿环境土遗址的保护一直是非常困难的课题。当遗址与其他材质的文物共存时,保护难度更高。为了探讨遗址博物馆内病害发生的规律和影响因素,为未来潮湿环境土遗址保护措施的研究和设计提供依据,以杭州市萧山区跨湖桥遗址为例开展调查研究。发现盖棚可以防止雨水对土遗址的破坏,但造成了水和盐的单向迁移,是目前土遗址病害的主要根源。对于室内遗址博物馆,如何解决遗址土体水分单向迁移带来的破坏已经成为迫切需要开展研究的课题,建议尽快开展室内土遗址补水技术的实验研究。     

Detection of chloride from pottery as a marker for salt: A new analytical method validated using simulated salt-making pottery and applied to Japanese ceramics

Salt is an essential mineral in the human diet, and ancient peoples obtained salt either directly from rock salt, from salt lakes, or by concentrating saline waters from salt springs or seawater in pottery vessels. However, because sodium chloride, the major component of salt, is soluble in water, it has been thought unlikely that any trace of salt would remain in the pottery after a long period of time. A new methodology for retrieval of water-insoluble (retainable) chloride ion trapped within a pottery matrix is presented as a method for detecting previous use of the pottery for salt making. Simulated salt-making pottery was used to make salt by repeatedly boiling seawater over a fire. After chloride had been extracted with distilled water, to mimic the removal of chloride by natural waters such as rainwater and groundwater, an aqueous ammonium fluoride solution was shown to be capable of extracting chloride ions remaining in the pottery. A chloride-selective electrode was used to quantify the amount of extracted chloride in the presence of fluoride. This method was then successfully applied to excavated Japanese pottery vessels suspected of having been used for making salt. Identification of retainable chloride in pottery can offer insights into salt trading networks, which reflect the growth and affluence of an ancient society.

山东寿光机械林场东周盐业遗址发掘简报

2017年,山东寿光机械林场遗址Ⅰ区、Ⅲ区共清理各类遗迹30余处,包括灰坑、盐井和盐灶等。出土器物有圜底瓮、鬲、豆、盆、罐、瓦等,绝大部分为残片,以圜底瓮残片为大宗,器物年代集中于战国早中期。初步判断该遗址为战国时期一处煮盐作坊。     

土质文物盐害中硫酸钠的研究——从微观到宏观

土遗址和壁画遗址可溶盐主要为NaCl和Na_2SO_4,其中Na_2SO_4是破坏程度最严重的盐。一般认为,硫酸钠只有在温度、湿度变化时才不稳定,才发生得失结晶水引起的晶型及体积变化。为研究土质文物盐害的形成机制及内在原因,调研了全国几处典型土遗址和壁画遗址的盐害状况并取样分析。分析发现:1)土遗址和壁画遗址中硫酸钠的形貌、结构是动态变化的(无论在任何极端干燥环境甚至真空条件下);2)环境因素如温度、相对湿度的变化只是加剧上述变化进程。硫酸钠结晶析出时,其体积膨胀约4倍。这一系列的过程,深刻影响着硫酸钠的相变复杂性和对依存土质文物本体的破坏性。本工作从微观和宏观两个层面探讨了这些发现,并通过不同盐分(不同浓度氯化钠、硫酸钠)侵蚀破坏模拟试验、不同温度条件下模拟试验、不同相对湿度下模拟试验,从宏观层面印证了上述微观机制在土遗址和壁画遗址本体的外在表现。本研究发现土遗址中硫酸钠的形貌、结构是动态变化的,该工作弥补了以往研究和认识上的局限。本研究将对阻止、延缓及预测土质文物盐害的发生、发展提供科学参考。
