Non-destructive analysis of nineteenth century Scottish calotype negatives and salt prints
Nineteenth century negatives and positives in the collections of the National Museums of Scotland (NMS) and the National Galleries of Scotland (NGS) were analysed non-destructively to identify the techniques used in their manufacture. Modern positive and negative images prepared using known nineteenth century processes were also analysed for comparison. Air-path...Eremin, Katherine ; Tate, Jim ; Morrison-Low, A D ; Berry, James ; Stevenson, Sara

West Highland Sculpture, Scotland – defining a Gaelic Lordship
The graveyards of the West Highland of Scotland contain many commemorative crosses and grave-slabs dating from the 14th to mid 16th century. They are carved in distinctive style from a variety of rock types. Their distribution largely coincides with the Lordship of the Isles, a powerful Gaelic Princedom, often in...Caldwell, David H ; Eremin, Katherine ; Miller, S ; Ruckley, N A

On the chemistry of John and Robert Adamson’s Salted paper prints and calotype negatives
The chemical processes used by John and Robert Adamson and the possibility that they might have used some special ingredient has long been the subject of speculation. In the early stages of photography in Scotland, the chemical processes used were probably based on William Henry Fox Talbot's, but it is...Eremin, Katherine ; Tate, Jim ; Berry, James

Understanding glass deterioration in museum collections: a multi-disciplinary approach
Raman spectroscopy and secondary ion mass spectrometry were used to investigate chemical and structural changes in soda and soda-lime glass exposed to organic pollutants under ambient and accelerated ageing conditions. Raman spectroscopy reveals modification of the glass structure non-destructively, in situ, and as a function of depth. The pollutants caused...Robinet, L ; Fearn, Sarah ; Eremin, Katherine

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
