A more complete overview of the characteristics of the layers in the investigated car paint fragment is given in Table 2. The pigment compositions in the second column are extracted from the XRD tomograms in Fig. 4. The top layer (1, white) of the multilayer contains rutile. In the four layers below (2–5), talc and aluminum are present, which are known to be used for adding strength to the coating and for providing a reflective luster. The diffraction patterns of layer 5 show a small amount of hematite, which is not visible in the hematite tomogram in Fig. 4 because of the (much) higher concentrations in layer 2 and 4. Layer 6 can be subdivided in two layers (6a and 6b), one of which contains goethite.
