Raman Explored: Unveiling the past 
A seminar highlighting research breakthroughs in cultural heritage and geoscience

From fossil forgeries to future resources
Richard Unitt, Research Fellow, University College Cork

Raman is still an emerging technology in the field of geoscience/geology, and we have taken on projects where there are little or no previous studies to provide reference material. As such, we are often leading the way in publishing detailed petrographic Raman maps, sometimes in 3D, as well as developing new methodologies to examine exceptionally preserved fossils. This talk will cover a number of published studies as well as ongoing research where Raman spectroscopy has proved to be an essential tool for enhancing our understanding of the natural world. 




Going where no Raman has gone before: Spectroscopy on Mars
Joseph Razell-Hollis, Postdoctoral Researcher, Natural History Museum, London

Raman spectroscopy, a vital tool for chemical analysis on Earth, has been utilized on Mars since July 2021. The SHERLOC instrument aboard NASA’s Perseverance rover employs deep-ultraviolet (DUV) Raman spectroscopy to identify minerals and organic compounds, aiding the search for evidence of past life and habitability on Mars. Joseph will summarize the mission’s findings from the first few years and discuss the unique challenges of conducting Raman spectroscopy on another planet.




Uncovering the secrets of our past with a VIRSAtile Raman Analyser
Dale Boorman, Sales Manager, Renishaw

If samples are too large to fit under a conventional microscope or if they can’t be moved to a lab environment, then we need a versatile instrument which can analyse samples on the move, but without compromising performance. Cultural heritage samples are often large, fragile and/or highly valuable, which limits sample preparation and adds to the challenge of obtaining high quality Raman spectra. We will describe how the Renishaw Virsa™ Raman Analyser provides an innovative solution to this problem, and we will show how it has been used to analyse artefacts in situ to help us better understand their underlying stories.




⁠Old objects, new pigments: unexpected findings in cultural heritage collections
Lucia Burgio, Lead Conservation Scientist, Victoria and Albert Museum

Occasionally, 'new' pigments can be found unexpectedly within museum collections, hiding in plain sight. In recent years, four of them have been discovered at the V&A on objects from different continents, spanning multiple centuries. Find out more about bismuth white, mercury white, bismuth grey and spherical copper resinate, and learn about the objects that are decorated with them.




⁠Beyond the Brushstroke: Raman spectroscopy and the detection of art forgeries
Denis Moiseev, CEO and co-founder, ArtDiscovery

For centuries, art experts have battled forgers in an ongoing arms race, with each side continuously evolving their techniques. In recent years, Raman spectroscopy has emerged as a powerful tool, providing experts with a significant advantage in detecting forgeries. Through a series of case studies, this talk will explore the critical role of Raman spectroscopy in the identification of art forgeries and discuss how this advanced technique could eventually render forgery a relic of the past.




⁠Raman Spectroscopy: a tool for teaching research-based cultural heritage
Paul Garside, Lecturer in Conservation Science, University of Glasgow

At the Kelvin Centre for Conservation and Cultural Heritage Research (University of Glasgow), Raman spectroscopy has an important role in both research and teaching. It is a particularly useful way of introducing students to complementary analysis (alongside techniques such as XRF and FORS), allowing them to explore strengths and limitations of analysis, in addition to sampling and interpretation. By doing so, they are also able to carry out their own research (recently on important manuscripts such as the Historia de Tlaxcala and the Margarita Philosophica), as well as appreciating staff-led research on materials including iron gall ink and parchment.




⁠The mineralogical composition of the Altar Stone at Stonehenge
Sergio Andò, Associate Professor, University of Milano-Bicocca

Megalithic Stone 80 at Stonehenge, the so-called Altar Stone, is a grey-green micaceous sandstone, anomalous for its composition and enigmatic for its provenance. To solve this conundrum, our team have collected new mineralogical data with a Renishaw Raman inVia™ on the Altar Stone fragment MS1, which indicates that the Old Red Sandstones in central England are not the source. This mineralogical database was applied to the in-situ, non-destructive investigation of the Altar Stone at Stonehenge, using a Renishaw Virsa™ Raman analyser. This experiment is important as we broaden our horizons in our search for the origin of the Altar Stone in other parts of Britain.




⁠Exploring the world with Raman inside the SEM
Jorge Diniz, Senior Application Scientist, Renishaw

Multi-modal sample analysis is essential to thoroughly characterise and understand our samples and materials. The inLux™ SEM Raman interface allows simultaneous and colocalised SEM and Raman imaging on one system, determining chemical composition, molecular and crystalline structure, and elemental composition, all at high resolution without moving the sample. We will show how using the inLux interface enhances material understanding and also demonstrate the power and ease of combining these techniques inside a SEM.
