Journal articleAs 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...

Journal articleSeveral 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...
