Data and scripts from: Noninvasive identification of carbon-based black pigments with pump-probe microscopy

Carbon-based black pigments a widely used class of pigments are difficult to differentiate with the noninvasive techniques currently used in cultural heritage science. We utilize pump-probe microscopy to distinguish four common carbon-based black pigments as pure pigments as two-component black pigment mixtures and as a mixture of a black and a colorful pigment. This work also demonstrates that even nominally "homogeneous"pigments present remarkable and useful heterogeneity in pump-probe microscopy.
