Microscopic Analysis of Wall Painting Techniques: Laboratory Replicas and Romanesque Case Studies in Southern Switzerland

The identification of painting techniques is an important aspect of any research related to historical, artistic, and conservation issues in the field of wall paintings conservation. There are a variety of different methodological approaches that can be used to identify wall painting techniques. In this study, the application of optical (PLM) and electron (SEM-EDX) microscopy was explored as they are complementary analytical techniques commonly used for micro-stratigraphic analysis of painted surfaces. Five replicas were prepared according to the technical procedures reported in medieval historical treatises, and the pigment was applied at different time intervals in order to monitor the modifications at the interface between the ground and pictorial layer. The comparison of data from the replicas with samples from Romanesque wall paintings in churches in Southern Switzerland and Northern Lombardy (Italy) allowed for an evaluation of the reliability of the proposed methodology and for the interpretation of the painting techniques.     

Deterioration Assessment and Conservation of a Heavily Degraded Korean Stone Buddha from the Ninth Century

Abstract

The standing Buddha image of Jincheon in the Republic of Korea created in the fourth year of Taehwa is engraved on a darkgray rock wall of shale. The front face has a backward inclination, meeting the strike of N40°W almost vertically. The host rock contains well-developed fine laminations and stratifications, and has small and large discontinuous planes irregularly distributed. Exfoliations make it hard to make out each part of the body. The surface of the surrounding rocks is severely contaminated with lichen and Bryophyta, and plant roots aggravate the mechanical and biological weathering. The rocks went through a series of conservation treatments, which consisted of dry cleaning followed by wet cleaning using distilled water. Broken or cracked parts were filled in or glued together using epoxy resin, surfaces with exfoliations were treated with ethyl silicate to become water-repellent and hardened. The color of the repaired parts was matched to harmonize with the rest of the image. Drainage was created to divert rainwater from the slope above away from the image, and surrounding plants were removed to control lichen growth. The bedrock of the Buddha image is deteriorated in its functions due to the surface weathering, therefore it is necessary to implement long-term monitoring and to search for comprehensive conservation solutions.     

Contradiction and Overdetermination in Occupy Wall Street

Contradiction and overdetermination in the work of Louis Althusser provide conceptual resources for the theorization of capitalism as a structural totality, and instances of class struggle, such as Occupy Wall Street, as part of an immanent movement of movements that is embedded within and against the differential logic of the mode of production. A reconsideration of Althusser is warranted on the grounds that his early work resonates theoretically with cutting-edge theoretical formulations of Autonomist Marxism, it remains useful to any materialist conceptualization of class struggle and history, and it provides means of assessing the conditions under which instances of class struggle transform into revolutionary situations.     

广州地区公藏石刻文献情况调查-兼论地区石刻文献数据库的建立

综合运用实地勘察、问卷调查、专家访谈以及因特网辅助调查4种方法,于2010年1月就广州地区石刻拓片收藏情况、广州地区石刻文献专藏情况以及广州石刻文献地区特性等进行了调查。根据调查反馈,首先总结了广州地区公藏石刻拓片的情况,包括基本情况、保存情况、整理情况和利用情况;继而结合理论研究,在肯定地区石刻文献的区域文化价值的基础上,从突出地区石刻文献的区域文化特性和深度揭示地区石刻文献信息两方面探讨了建立地区石刻文献数据库的设想。

Cellulose degradation in the Vasa: The role of acids and rust

Abstract

The oak timbers of the Swedish warship Vasa are deteriorating. High amounts of oxalic acid have been found along with a low pH and low molecular weight cellulose deep in the wood timbers. The iron-rich surface wood differs from the interior wood in that it displays higher pH and cellulose with higher molecular weight. The objective of this study was to determine why there is a difference in cellulose degradation, pH, and oxalic acid amount between the surface region and the interior of the Vasa timbers. Analysis of cellulose weight average molecular weight by size exclusion chromatography was performed, as well as quantification of oxalic acid and iron by high-performance anion exchange chromatography and atomic emission spectroscopy, respectively. It was found that a decrease in iron content coincides with an increase in oxalic acid concentration and a drop in pH at a certain depth from the wood surface. When iron-rich surface wood samples from the Vasa were mixed with an aqueous solution of oxalic acid, a fast increase of pH over time was observed. Neither interior wood poor in iron nor the fresh oak reference showed the same neutralizing effect during the time of measurement. This indicates that the presence of iron (rust) causes a neutralization of the wood, through the formation of iron(III) oxalato complexes, thus protecting the wood from oxalic acid hydrolysis. This effect was not observed to the same extent for other acids observed in Vasa wood (sulfuric, formic, glycolic, and acetic acids).

图书馆装饰设计中装饰画的选择

装饰画表现出图书馆的艺术风格与文化品位。适当挂置装饰画可以提高图书馆室内整体的和谐度。现代化图书馆选择装饰画应从装饰画的主体颜色、内容、形式、风格、图案、样式及形状等方面考虑,选择与所处空间环境相呼应、与图书馆的功能相匹配、与图书馆的文化积淀与地域特色的个性化相融合的装饰画。

The Social and Historic Construction of Professional Values in Conservation

Summary

This paper discusses the social history of the emergence of conservation as a profession distinct from traditional restoration. It proposes that the development of conservation as a distinct field came about through the evolution of an existing area of practice, in a changing conceptual climate which increasingly acknowledged the necessity for, and the legitimacy of the scientific model. This paper considers the changes in societal values that led conservators to hold their present ethical principles, values and beliefs, focusing on two in particular: the importance of preserving the integrity of the object, and the belief that the best way to do this is through the application of science.
