Raman spectroscopy of coloured resins used in antiquity: dragon's blood and related substances
Dragon's blood is a deep red resin which has been used for centuries by many cultures and much prized for it's rarity, depth of colour and alchemical associations. The original source of dragon's blood resin is believed to be Dracaena cinnabari from Socotra in Africa, but since mediaeval times there...Edwards, Howell G M ; de Oliviera, Luiz Fernando C ; Quye, Anita

‘Dragon’s Blood’ I—characterization of an Ancient resin using Fourier transform Raman spectroscopy
Several resins generically known as ‘dragon’s blood’ from different botanical and geographical sources were characterised non‐destructively using Fourier transform Raman spectroscopy. Genuine ‘dragon’s blood’ resin (Dracaena spp.) as found on Socotra Island was the probable source in antiquity. The spectra of recently collected Socotran resins from different sites were compared...Quye, Anita ; Edwards, Howell G M ; Farwell, D W

Mummy 1911-210-1
n ancient Egyptian mummy from the collections of the National Museums of Scotland was examined using computerised tomography (CT) scanning as part of the NMS mummy project. A facial reconstruction was produced from the CT scans for comparison with a painted 'portrait' which covers the face of the wrappings. The...Macleod, R I ; Eremin, Katherine ; Wright, A R ; McDonald, J

Non-destructive analysis of nineteenth century Scottish calotype negatives and salt prints
The combination of Raman spectroscopy and Secondary Ion Mass Spectrometry can improve understanding of the chemistry of the glass alteration process. Formic and acetic acids play an important role in the alteration of museum glass objects placed in a humid atmosphere. Raman spectroscopy indicates that the soda-rich glass structure is...Robinet, L ; Eremin, Katherine ; Fearn, Sarah ; Pulham, C ; Hall, Christopher

Ancient genomes indicate population replacement in Early Neolithic Britain
The roles of migration, admixture and acculturation in the European transition to farming have been debated for over 100 years. Genome-wide ancient DNA studies indicate predominantly Aegean ancestry for continental Neolithic farmers, but also variable admixture with local Mesolithic hunter-gatherers. Neolithic cultures first appear in Britain circa 4000 bc, a millennium after...Brace, Selina ; Diekmann, Yoan ; Booth, Thomas J ; Faltyskova, Zuzana ; Rohland, Nadin …
