These results were confirmed with other nondestructive techniques, including X-ray fluorescence and optical fiber reflectance spectroscopy.Then, the researchers mixed pigments from a commercial acrylic paint brand (used in Germany since the 1800s) with different ratios of titanium white, trying to match colors and the range of tints typical for painters. A knowledge of these ratios could help art conservators prepare the right materials for restoration, say the researchers. Using the mixtures%u2019 handheld Raman spectral data, they trained a machine learning algorithm to determine the percentage of pigment. The approach indicated that the Berlin Wall paint chips contained titanium white and up to 75% of pigment, depending on the piece analyzed and according with the color tone. The researchers say these results indicate that their AI model could provide high-quality information for art conservation, forensics and materials science in settings where it%u2019s hard to bring lab equipment to a site.TURKCOAT Haziran / June - Temmuz / July 2025Bilimsel / Scientific54%u015f%u00fcn%u00fcl%u00fcyor.
