Investigation of inherent degradation in cellulose nitrate museum artefacts
Cellulose nitrate was one of the first semi-synthetic plastics to be commercially exploited and as such many museums contain a large number of artefacts illustrating the versatility of this plastic for the creation of a wide variety of functional and aesthetic artefacts. Conservators find themselves faced with the challenge of...Quye, Anita ; Littlejohn, D ; Petherick, R ; Stewart, R

The practice of dyeing wool in Scotland c.1790-c.1840
The history of dyeing is complex, even when analysed over a short period of time and in a comparatively small country such as Scotland. There are hundreds of dyes, natural and manufactured; most require the use of further chemicals as mordants to fix the colour; dyes interact with different vegetable...Burnett, John ; Mercer, Katherine ; Quye, Anita

Characterisation of ‘bog butter’ using a combination of molecular and isotopic techniques
The chemical analyses of ‘bog butters’ recovered from peat bogs of Scotland were performed with the aim of determining their origins. Detailed compositional information was obtained from ‘bog butter’ lipids using high temperature gas chromatography (HTGC) and GC-mass spectrometry (GC-MS). The results indicate the degree to which ‘bog butters’ have...Berstan, Robert ; Dudd, Stephanie N ; Copley, Mark S ; Morgan, E David ; Quye, Anita …

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

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

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
