Raman spectra (λexc = 633 nm) for selected pigments present in Jama-Coaque ceramics (thick lines). Reference spectra (thin lines) and selected peaks for clay (squares)39, copper phthalocyanine (circles)37, goethite (triangle up)34, hematite (triangle down)33, and carbon black (diamond)35 are provided for comparison. The sample and colour as background are provided to the right of each spectra.
