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 characterisation of metal soaps
To characterize more fully the metal soaps found in paint films or on metal surfaces, several metal soaps were synthesized and their X-ray diffraction pattern and Fourier transform infrared (FTIR) and Raman spectra measured. Metal soaps were obtained from four different fatty acids found in drying oils — two saturated...Robinet, Lauren ; Corbeil, Marie-Claude

By the mandate of heaven': a kingfisher-feather headdress in the National Museum of Scotland
This article focuses on a kingfisher headdress selected for the new East Asia gallery at the National Museum of Scotland. Dating to the late Qing dynasty and previously thought to be part of an opera costume, new research has revealed that this intricate headdress might instead have been the property...Cao, Qin

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 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

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
