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

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

Non-destructive analysis of museum objects by fibre-optic Raman spectroscopy.
Raman spectroscopy is a versatile technique that has frequently been applied for the investigation of art objects. By using mobile Raman instrumentation it is possible to investigate the artworks without the need for sampling. This work evaluates the use of a dedicated mobile spectrometer for the investigation of a range...Vandenabeele, Peter ; Tate, Jim ; Moens, Luc

Excavation at Aguas Buenas, Robinson Crusoe Island, Chile, of a gunpowder magazine and the supposed campsite of Alexander Selkirk, together with an account of early navigational dividers
Excavations were undertaken of a ruined building at Aguas Buenas, identified as an 18th-century Spanish gunpowder magazine. Evidence was also found for the campsite of an early European occupant of the island. A case is made that this was Alexander Selkirk, a castaway here from 1704 to 1709. Selkirk was...Takahashi, Daisuke ; Caldwell, David H ; Caceres, Ivan ; Calderon, Mauricio ; Morrison-Low, A D …

Alteration of soda silicate glasses by organic pollutants in museums: Mechanisms and kinetics
The role of the organic pollutants formic acid, acetic acid and formaldehyde in the alteration of unstable soda silicate glasses is examined through SIMS depth profiling of replica glass aged in polluted and non-polluted atmospheres under ambient conditions. The effect of different controlled atmospheres is compared to the polluted atmosphere... -

The 17th dynasty gold necklace from Qurneh, Egypt
In 1908, the archaeologist Flinders Petrie discovered a rich intact burial of an adult and child at Qurneh, near Luxor. Stylistically, the burial has been dated to the late 17th Dynasty, in the 16th century BC. The complete burial group came to Edinburgh in 1909. A recent examination of the...Tate, Jim ; Eremin, Katherine ; Troalen, Lore ; Guerra, Maria Filomena ; Goring, Elizabeth …

Monitoring copper and silver corrosion in different museum environments by electrical resistance measurement
The results are reported of a systematic programme of electrical resistance measurement (ERM) of copper and silver corrosion rates within various museum environments, directed towards developing preventive conservation understanding and practice. Electrical resistivity measurements were made using copper and silver probes for one month and one year in 33 locations,...Dubus, M ; Kouril, M ; Nguyen, T P ; Prosek, T ; Saheb, M …
