Wall Painting Fragment

Pink and red pigment on brown-white plaster. Pink ground with darker red-pink stripes. Samples of the pigments and plaster were taken and analyzed in the Straus Center in 2023. Ultraviolet-induced fluorescence imaging produced results consistent with madder lake pigment in the pink, while Fourier transform infrared spectroscopy (FTIR) analysis resulted in the identification of gypsum in both the white and pink. The plaster was identified as gypsum plaster.
