这个项目的基本概念是识别并利用传统绘画介质的化学和物理性质的变化来表明和整合环境条件对绘画的影响。为了实现这一目标，测试漆膜正在按照传统艺术家的食谱准备。使用非侵入性光谱（Bacci），微传感器，热分析技术（Odlyha）和用于分子结构分析的微尺度分析质谱（Boon）的组合来监测材料性能的变化。测试条通过暴露在受控环境（光、温度、相对湿度和有害气体）中进行校准，并对其性能的变化进行量化。这提供了关于分子水平变化的性质和速率的信息，并为分子监测条在野外暴露后的评价提供了数据库。现场场地已经选定，包括泰特美术馆（英国）、桑德姆教堂（英国Burghclere）、乌菲齐美术馆（It）和荷兰国立博物馆（NL）的各个地点。目前正在使用EV5VCT92 0144项目中描述的玻璃传感器评估其中一些地点的环境条件。小型压电石英晶体湿度传感器将安装在桑德姆教堂的斯坦利·斯宾塞画作和乌菲齐美术馆的乔托的《奥格尼桑蒂圣母》上，以确定局部相对湿度和温度的变化。此外，使用图像清漆的新型涂层也被应用于类似的压电石英晶体传感器，以评估环境对油漆清漆化学性质的影响。在分子水平上，也正在收集有关实际绘画中清漆和油漆介质的化学和物理变化性质的数据。
The basic concept of this project is to identify and then use the changes which occur in the chemical and physical properties of traditional paint media both to indicate and integrate the effects of environmental conditions on paintings. To achieve this aim, test paint films are being prepared in accordance with traditional artists' recipes. Changes in material properties are monitored using a combination of non-invasive spectroscopy (Bacci), microsensors, thermoanalytical techniques (Odlyha), and microscale analytical mass spectrometry for molecular structure analysis (Boon). The test strips are calibrated by exposure to controlled environments (light, temperature, relative humidity and noxious gases) and alterations in their properties are quantified. This provides information on the nature and rate of change at the molecular level and a data base for evaluating the molecular monitoring strips after their exposure in the field. Field sites have been selected and include various locations in the Tate Gallery (UK), Sandham Chapel (Burghclere, UK), the Uffizi Gallery (It) and the Rijksmuseum (NL). Environmental conditions of some of these locations are being evaluated at present using the glass sensors described in project EV5VCT92 0144. Small piezoelectric quartz crystal humidity sensors will be installed to determine localised variations in relative humidity and temperature on [I] Stanley Spencer paintings in Sandham Chapel and [2] Giotto's ''Madonna di Ognissanti'' in the Uffizi Gallery. In addition novel coatings using picture varnishes are being applied to similar piezoelectric quartz crystal sensors to evaluate the effects of environmental impact on the chemistry of varnishes on paintings. Data are also being collected on the nature of chemical and physical changes in varnishes and paint media in actual paintings at the molecular level.
