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

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
