Mummy 1911-210-1
n ancient Egyptian mummy from the collections of the National Museums of Scotland was examined using computerised tomography (CT) scanning as part of the NMS mummy project. A facial reconstruction was produced from the CT scans for comparison with a painted 'portrait' which covers the face of the wrappings. The...Macleod, R I ; Eremin, Katherine ; Wright, A R ; McDonald, J

Non-destructive analysis of nineteenth century Scottish calotype negatives and salt prints
The combination of Raman spectroscopy and Secondary Ion Mass Spectrometry can improve understanding of the chemistry of the glass alteration process. Formic and acetic acids play an important role in the alteration of museum glass objects placed in a humid atmosphere. Raman spectroscopy indicates that the soda-rich glass structure is...Robinet, L ; Eremin, Katherine ; Fearn, Sarah ; Pulham, C ; Hall, Christopher

Effect of organic acid vapors on the alteration of soda silicate glass
Organic acids were previously shown to be involved in the alteration of historic soda silicate glasses in humid atmospheres under museum storage conditions. The present study investigates the role of these pollutants on the visual, compositional and structural modification of soda silicate glasses. Replica glasses aged in humid or humid/acidic... -

The use of Raman spectrometry to predict the stability of historic glasses
In the National Museums of Scotland (NMS) widespread alterations have been observed in the glass collections of 19th to 20th century, affecting British, Islamic and Asian glasses. It is important for museums to be able to distinguish between stable and unstable glasses, so that particular care can be taken to...Robinet, L ; Eremin, Katherine ; Coupry, Claude ; Hall, Christopher
