Investigation of the degradation of cellulose acetate museum artefacts
Cellulose acetate artefacts from various museums have been analysed by micro-FTIR spectrometry and ion chromatography in an attempt to identify whether there are any common factors associated with their degradation. There was good correlation between the IR spectra, the concentration of ions extracted from an artefact and the visual degree...Littlejohn, D ; Petherick, R ; Quye, Anita ; Ballany, Jane M

Negative ion ESI–MS analysis of natural yellow dye flavonoids : an isotopic labelling study
Flavonoids are amongst the most commonly used natural yellow colourants in paintings, as lakes, and in historical textiles as mordant dyes. In this paper, evidence from isotopically labelled substrates is used to propose negative ion electrospray collision induced decomposition mechanisms of flavones, flavonols and an isoflavone. These mechanisms include a...McNab, Hamish ; Ferreira, Ester S B ; Hulme, Alison N ; Quye, Anita

Wroughte in gold and silk: preserving the art of historic tapestries
Wroughte in gold and silk features exceptionally important tapestries from major European collections; and shows the world-class research – scientific, artistic and historical – applied to their preservation. Presenting the interdisciplinary European Community-funded project 'Monitoring of Damage in Historical Tapestries' (MODHT), the research is described in an understandable and practical...Quye, Anita ; Hallett, Kathryn ; Herrero Carretero, Concha

The natural constituents of historical textile dyes
The sources and structures of dyes used to colour Western historical textiles are described in this tutorial review. Most blue and purple colours were derived from indigo—obtained either from woad or from the indigo plant—though some other sources (e.g. shellfish and lichens) were used. Reds were often anthraquinone derivatives obtained...Ferreira, Ester S B ; Hulme, Alison N ; McNab, Hamish ; Quye, Anita

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

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
