Effects of emissions of materials for wrapping, transportation and storage on stained glass windows and on glass objects in show cases in museums

  • The emission of volatile organic compounds (VOC) of materials for wrapping, transportation and storage of stained glass windows were investigated by direct thermal desorption. The analysis was performed with thermal desorption in combination with gas chromatography and mass spectrometry. Emissions of organic acids were determined. The damage risk of volatile organic compounds, e.g. organic acids as acetic acid, propanoic acid, hexanoic acid and octanoic acid was investigated on model glasses in climate chambers. After exposure the surface of the most sensitive samples was damaged. Based on emission measurements in exhibit cases of the former museum "Grünes Gewölbe in the Albertinum" in Dresden, Germany, the atmospheric conditions inside the show cases were determined. It can be shown that the atmospheric conditions inside the cases endanger the glass and enamel objects of art especially in show cases with low air exchange rates.

It can be shown that the atmospheric conditions inside the cases endanger the glass and enamel objects of art especially in show cases with low air exchange rates. Materials with high emission rates of organic acids should not be in direct contact with medieval glass for a long time and should not be used in exhibit cases. Acid emissions, especially acetic acid plays an important role during investigation of different materials for show cases and can be determined by direct thermal desorption.zeige mehrzeige weniger
