The analytical characterisation of the main component found in logwood dyed textile samples after hydrochloric acid extraction
The triennial meetings of the ICOM Committee for Conservation (ICOM-CC) are widely regarded as the most significant global events in the heritage conservation calendar. At each Congress, the membership of the ICOM-CC are brought together to report and to review current research. The meetings offer the conservation professional a unique...Hulme, Alison N ; McNab, Hamish ; Peggie, David A ; Quye, Anita ; Vanden Berghe, I …

The application of liquid chromatography–mass spectrometry and accelerated light ageing for the analytical identification of yellow flavonoid dyes in historical tapestries
Papers in this volume cover various aspects of the deterioration of textiles and the different scientific techniques that can be applied to investigate the characteristics of historic textiles, their fibres, dyes etc. The authors include textile, paper and painting conservators, conservation scientists, chemists, archaeologists, engineers, biochemists and a zoologist.

Negative ion electrospray mass spectrometry of neoflavonoids
The electrospray ionisation mass spectra of the neoflavanoids brazilin and hematoxylin are reported in both their reduced (1 and 2, respectively) and their oxidised forms (3 and 4, respectively). In the reduced forms, breakdown pathways under collision induced decomposition (CID) conditions produce fragments characteristic of rings A and C; in...Hulme, Alison N ; McNab, Hamish ; Peggie, David A ; Quye, Anita

2',4',6'-Trihydroxy-1-methoxyacetophenone monohydrate at 150 K
The geometry of the title compound, 2-methoxy-1-(2,4,6-trihydroxyphenyl)ethanone, C9H10O5·H2O, is determined by the presence of an intramolecular hydrogen bond; the geometry of the benzene ring is distorted by a flanking carbonyl group.Ferreira, Ester S B ; Hulme, Alison N ; McNab, Hamish ; Quye, Anita ; Parsons, S

Development of analytical techniques for the study of natural yellow dyes in historic textiles
Interest in all aspects of dyestuffs has grown considerably since an informal meeting of researchers twenty years ago developed into the annual meetings of Dyes in History and Archaeology, with the journal of the same name publishing a selection of papers presented. Analysis has revealed that the early 20th-century clothing...Ferreira, Ester S B ; Quye, Anita ; McNab, Hamish ; Wouters, J ; Boon, J J …

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
