Changes in the body,glaze and enamel compositions of early Meissen porcelain, 1723–c.1740

The evolution of early Meissen body, glaze and colorant compositions is examined using X-ray fluorescence spectroscopy (XRF) measurements on three artefacts that can be accurately dated to the period 1723–c.1740. The results are interpreted based on recipes recorded in the earliest documents of the Meissen archives. The pure Aue kaolinite contains low levels of Ti and can be distinguished from secondary clays, for example, clay from Colditz. The excess Ti in the glaze versus the body reported earlier and confirmed by the present authors is explained by the exclusive use of Colditz clay for the glaze, as described in the recipes before 1730, providing a terminus ante quem for Meissen porcelain exhibiting this particular asymmetry. After 1730, the presence of elevated Ti in the body could serve as a marker for the experimental admixture of clays to Aue kaolinite to alter its properties. Based on the detection of As, Ba and Bi, it is suggested that smalt from Erzgebirge was the colorant for blue enamels until at least 1725.     

“中国西南与东南亚地区冶金技术的起源与传播暨临邛冶铁实验考古”国际学术研讨会综述

2019年11月,"中国西南与东南亚冶金技术的起源与传播暨临邛冶铁实验考古"国际学术研讨会在四川邛崃市召开。来自海内外的百余位学者,就中国西北与西南、中亚、东南亚地区冶金技术的起源与传播进行深入探讨,并在临邛汉代冶铁实验考古现场就汉代冶铁和炒钢的技术与工艺、考古遗迹与各个生产环节的对应关系、出土冶铸遗物的科技检测分析等问题展开讨论。与会代表一致认为,研讨会的召开不仅展示了亚洲大陆冶金考古的新发现和新成果,临邛冶铁实验考古也为今后冶金考古研究提供了新的思路和有效借鉴。     

文物的赋存环境及其预防性保护问题

我国是世界上历史最悠久的古国之一,拥有为数众多的具有历史、科学、社会及经济价值的文物。本研究尝试综述了从文物与其赋存环境关系的角度,将文物赋存环境分为全曝露自然环境、半曝露自然环境及人工营造环境,通过分析赋存环境对文物的影响,探讨文物赋存环境的转化过程,提出不同环境条件下文物的预防性保护问题。     

数字时代博物馆版权例外制度的困境与出路

全球博物馆在技术发展的加持下进入了新的发展阶段,数字化建设、藏品资源分享以及文创产品开发成为博物馆“角色转变”的新标杆。然而,现有的版权例外规则并不能满足博物馆的发展需求,更无法契合博物馆开放的馆藏作品的传播姿态,无力贴合博物馆文创产业发展的诉求。基于此,有必要通过适当放宽博物馆数字化建设的版权例外空间、合理延伸博物馆藏品传播的版权例外适用范围以及高效运用法定许可规则助推博物馆文创产业发展等措施,实现我国博物馆版权例外制度在数字时代下的良性变革。     

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。     

The Post‐Industrial “Shop Floor”: Emerging Forms of Gentrification in San Francisco's Innovation Economy

The San Francisco Bay Area in California is undergoing a technology‐driven wave of growth arguably more thoroughgoing than the first “dot‐com” bubble, fueling hypertrophic gentrification and tales of a deeply class‐divided, “Blade Runner kind of society”. While Silicon Valley is still the industry's employment center, San Francisco is seeing faster tech firm growth, and is transforming its downtown to become more “livable” and promoting public space as key to innovation. In this context, this paper offers a reading of urban public space not just as a consumption amenity but also as the “shop floor” of a labor process that goes beyond the walls of the firm to mobilize the social itself in the production of privately appropriated value. With innovation now the watchword of gentrification, the stakes of this shift oscillate between the total commodification of urban vitality and the recognition of the social process of value production itself.     

Pottery Production in the Buddhist Communities in Central Asia: The Kushan‐Sassanian Pottery Workshop of Kara Tepe (Termez,Uzbekistan)

We present the first full archaeometrical study of Kushan‐Sassanian pottery from the Buddhist monastic complexes at Kara Tepe (Termez, Uzbekistan), recovered both in the pottery workshop and in the monastery, using a combination of analytical methods (XRF, XRD, SEM–EDS and OM). The study allowed the identification of the reference group, the correspondent fabric, the raw materials used for its productions, some of the technological processes involved in manufacture and several weathering processes. All the results confirm that the kiln was supplying the religious community of the monastery with pottery, made using local raw materials, and highlight the possibility that the kiln could have supplied the nearby monastic complexes, where no kilns have been found. Further archaeological evidence indicates the existence of specialized potters working itinerantly at the broader Bactrian area.     

谈我国纸质文物保护的科技需求

我国纸质文物数量众多而保护难度较大。纸质文物因其特殊的本体材料、性能,病害原因多样、易于损毁,特别是民国纸质文物损坏现象严重。纸质文物保护需要建立完善的文物数据库和检测体系,以现代科学方法展开劣化机理研究,结合不同地区气候条件,以本国传统产纸技术、修复体系为根基,引入国际先进技术,达到长期、稳定保存纸质文物的目的。     

Something to Compete with ‘Gunsmoke’: ‘The Big Picture’ Television series and selling a ‘modern,progressive and forward thinking’ Army to Cold War America

Airing from 1951 until 1971, ‘The Big Picture’ was the United States Army’s primary means of marketing itself to the U.S. public, particularly between the Korean and Vietnam Wars. Drawing for the first time on archival records concerning the show’s production, this paper documents how information officers sought to escape the stock-footage straightjacket embedded in the show’s origins and showcase an Atomic Age Army standing sentry at the Cold War’s ramparts. Ultimately, they fought dual losing battles against parsimonious budgets and public indifference, while their insistence on content control hampered potential exposure in more appealing prime-time entertainment programmes.
