This chapter delves into the multifaceted application of Raman spectroscopy as a pivotal forensic tool in the realm of cultural heritage preservation. It intricately examines various scenarios where Raman spectroscopy plays a crucial role in evaluating the authenticity and composition of diverse artefacts. One significant focus is on the assessment of an artwork destroyed by fire, where the analysis of ashes resulting from the burnt painting provides essential insights into the originality of materials present. This meticulous investigation underscores the importance of Raman spectroscopy in unravelling the molecular details that can shed light on the provenance and integrity of cultural treasures.
Moreover, the study extends its scope to the evaluation of Brazilian stamps, employing Raman microscopy to identify the composition of postmark inks. By confirming the presence of pigment, triglyceride, and proteinaceous materials, the research contributes to the authentication process of these historical artefacts. Additionally, the analysis of lead-based paints, specifically identifying lead white, massicot, and litharge, showcases the technique’s versatility in characterising materials used in artistic creations.
Overall, the chapter underscores the significance of complementary analytical techniques in corroborating molecular information identified by Raman microscopy. This approach not only highlights the robustness of the technique but also emphasises its utility in forensic research for cultural heritage conservation. By providing a comprehensive and detailed analysis of materials, Raman spectroscopy emerges as a valuable tool in the preservation and understanding of our artistic and historical legacy.
