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... -

Goldwork in Ancient Egypt: workshop practices at Qurneh in the 2nd Intermediate Period
Described by Petrie as ‘the largest group of goldwork that had left Egypt’, the jewellery from the intact burial of an adult and child discovered at Qurneh in 1908 is the most important group of gold objects excavated in Egypt dating from the 2nd Intermediate Period (c. 1800–1550 BC). This...Troalen, Lore ; Tate, Jim ; Guerra, Maria Filomena

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 …

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

Material characterization and preservation guidance for a collection of prosthetic limbs developed since 1960
National Museums Scotland has collections relating to many areas of science and technology, including medical science. This paper considers technical and conservation issues of an important collection of more than 150 prosthetic limbs. Much of the collection is of prosthetics developed for children born lacking or with malformed upper limbs...Smith, Margaret J ; Kirk, Susanna ; Tate, Jim ; Cox, Darren
