Probing the factors which control degradation in museum collections of cellulose acetate artefacts
Cellulose acetate artefacts in museum collections cover a period from the early 1900's to the present day. Conservators have observed that certain of these objects are showing signs of warping, crazing, cracking, discolouration and shrinkage accompanied by a strong smell of acetic acid. Previous studies on cellulose nitrate artefacts show...Ballany, Jane M ; Littlejohn, D ; Pethrick, R P ; Quye, Anita

Degradation studies of cellulose nitrate plastics
This book addresses the interaction of principle and practice, of materials, techniques and ideas, which characterise contemporary conservation as a whole.Stewart, R ; Littlejohn, D ; Pethrick, R P ; Quye, Anita ; Tennent, N H

Analytical studies of the degradation of cellulose nitrate plastics in museums
This paper discusses a project which is examining the degradation of cellulose nitrate artefacts. Several analytical techniques including Fourier transform infrared (FTIR) spectroscopy and ion chromatography have been used to investigate the degradation processes occurring and the various factors influencing the rate of degradation. Accelerated ageing of cellulose nitrate has...Stewart, R ; Littlejohn, D ; Pethrick, R P ; Quye, Anita ; Tennent, N H

The use of accelerated ageing tests for studying the degradation of cellulose nitrate
Previous studies have shown that high levels of sulphate in cellulose nitrate artefacts may be a cause of increased degradation. Accelerated ageing tests have been used to study and monitor the deterioration of prepared cellulose nitrate samples and artefacts over time. An evaluation has been made of the effects of... -

The Museum of Scotland and conservation issues of commissioned art
The Museum of Scotland is a new building in Edinburgh which opened in November 1998 to present the history of Scotland from its geological beginnings to the present day. This article considers conservation issues within three themes: the building itself as iconic modern architecture and its effect on the exhibition...Tate, Jim ; Clarke, David V ; Spencer, Helen ; Cobo del Arco, B

Analytical study of the Middle Kingdom group of gold jewellery from tomb 124 at Riqqa, Egypt
The jewellery from tomb 124 at Riqqa, consisting of one pectoral and one winged beetle in gold and cloisonné work, one gold shell pendant decorated with wires and granulation, and one hollow gold amulet in the form of god Min, was analysed by handheld X‐ray fluorescence and scanning electron microscopy...Troalen, Lore ; Guerra, Maria Filomena ; Maitland, Margaret ; Ponting, M ; Price, C

A Raman spectroscopic study of pollution-induced glass deterioration
White crystalline deposits were present on a large number of 19th and 20th century British glass artefacts in the National Museums of Scotland collections. Analysis of these deposits by ion chromatography showed that sodium and formate were the dominant ions. Raman spectroscopy identified sodium formate anhydrate phase II as the...Robinet, L ; Eremin, Katherine ; Cobo del Arco, B ; Gibson, L T

A Raman spectroscopic analysis of pigments from Dynastic Egyptian funerary artefacts
As part of a comprehensive analytical survey, Raman spectra were obtained of pigments from ancient Egyptian funerary artefacts dating from the 17th Dynasty to the Graeco‐Roman period, using several laser excitation wavelengths. A wide colour palette has been identified with mineral pigments and pigment mixtures; several variations were detected with...Edwards, Howell G M ; Jorde Villar, S E ; Eremin, Katherine
