Cr logwood inks prepared following variations of a mid-19th century recipe were characterized by Raman spectroscopy, Fourier transform infrared spectroscopy, liquid chromatography–diode array detection–quadrupole time-of-flight–mass spectrometry, and liquid chromatography–inductively coupled plasma–mass spectrometry to determine their composition and to obtain Raman spectra for their identification in artworks and in historic documents. The Raman spectral references were used to characterize the ink used by van Gogh in Street in Saintes-Maries-de-la-Mer.
