ABM CONFERENCES ABM MEMBER EVENTS ABM Seminar Series - December 2024 Seminar Series Presenter When mould is a museum visitor – xerophilic fungal growth challenges environmental recommendations for heritage collections In the last decade, extensive fungal growth has developed in Danish museums parallel to climate change challenging occupational health and heritage preservation. The growth was unexpected as the museums controlled relative humidity below 60 %, according to international environmental recommendations for heritage collections. Only heritage artefacts were affected, there was no growth on building constructions, interior and museum boxes. A cross-sectional study using a multiple detection approach found that the culprits were extremophilic xerophilic fungal species able to grow at low relative humidity, which is most unusual for fungi. The study concluded that xerophilic fungal growth is nationally distributed and suggests these species as a novel contaminant in climate-controlled museum repositories. To safeguard occupational health and heritage preservation research in sustainable solutions, avoiding xerophilic growth in museum collections is most important. Explore PUBLICATIONS + PROJECTS

How do you start investigating ancient textiles, when you are not even sure where to start? What kind of materials are they made from? Is there any information in those materials that would help identify a geographic place or date for the origin of the materials (if not the textiles themselves)? If the material is dyed--and many textile fragments are multi-colored--how could we test the dye? And, again, could the dye analysis give us any clues as to geography and chronology? Are there any tests or analytical procedures that can shed any light on the weaving or making process? If possible tests or procedures are known, how does one set up such tests? What is needed? Is sampling necessary? If so, what size would the samples need to be? What are the costs involved? Juliet and Ilaria will be holding an informal conversation touching on various topics of interest to both curators and scientists investigating ancient textiles. Explore PUBLICATIONS + PROJECTS

She investigates paints, coatings, adhesives, and the organic materials found in artworks across all ages using spectroscopy (FTIR), mass-spectrometric (GC/MS, Py-GC/MS. MALDI, LCMS) and immunological techniques (ELISA), with emphasis on natural and synthetic polymer identification and degradation. Her research interests include interactions between pigments and binders, especially proteins, polysaccharides, lipids, and their mixtures. ABM CONFERENCES ABM 2021 Poster Presenter Why Antibodies for Art Analysis? Materials from animal and plant sources (biological materials) have been used by artists to create all forms of artworks throughout time. The challenge to cultural heritage scientists is to provide meaningful and accurate information to curators, art historians, and conservators about the fats, lipids, gums, and proteins that are chemically changed by pigments and binder interactions. Antibodies offer one avenue for the investigation of proteins and polysaccharides. This presentation will describe the pros, cons, and future of this approach.

For the first time, hydrogen‑deuterium exchange mass spectrometry (HDX-MS) was implemented to explore the conformational alterations of proteins resulting from their interaction with inorganic pigments within the early stages of the paint film formation. Intact protein analysis and bottom-up electrospray-ionisation mass spectrometry strategies combined with progressively increasing deuterium incubation times were used to compare the protein structures of the model protein hen egg-white lysozyme (HEWL) extracted from newly dried non-pigmented films and newly dried films made from a freshly made mixture of HEWL with lead white pigment (2PbCO3 Pb(OH)2). The action of other pigments was also investigated, expanding the HDX study with a global approach to paint models of HEWL mixed with zinc white (ZnO), cinnabar (HgS) and red lead (Pb3O4) pigments. The results show structural modifications of HEWL induced by the interaction with the pigment metal ions during the paint formulation after drying and prior to ageing. Both the charge distribution of HEWL proteoforms, its oxidation rate and its deuterium absorption rate, were influenced by the pigment type, providing the first insights into the correlation of pigment type/metal cation to specific chemistries related to protein stability. Explore Julie Arslanoglu Cutting Through the Fat: Animal Species and Food Processing Techniques of Residues Found in Nineteenth-Century Edgefield Pottery As part of the exhibition, Hear Me Now: The Black Potters of Old Edgefield, South Carolina, The Met’s Department of Scientific Research (DSR) investigated organic food residues found inside large nineteenth-century alkaline-glazed stoneware vessels from the Old Edgefield District, South Carolina. “Examining Storage Jars from the American South” describes the driving questions about the jars’ use and the users’ lifestyle. Investigations reported in “The Inside (and Outside) Scoop: Scientific Analysis of Food Residues Inside the Jars from Old Edgefield, South Carolina” established that the heterogeneous residues are mostly oily materials with solid materials of various unknown origins. We hoped to gain more information about the jars’ contents from these residues, but to do so we need the sophisticated tools and expertise of our collaborators through ARCHE. Explore

This approach,however, is not always applicable due to the deterioration of the archaeological objects.Paleoproteomics was used as an alternative approach to identify the species of origin of fifteensamples of various tissues from approximately 600‑year‑old garments found in Nuulliit, northernGreenland. Proteomics revealed that a limited group of marine and terrestrial mammals were usedfor clothing production. The results obtained from the analysis of multiple types of clothing andelements, such as sinew thread and gut skin, suggest that their applications were based on theirproperties. When conclusive assignment of a sample to a species via proteomics was not possible, theobservation by transmitted light microscopy of feather and hair micromorphology, if not affected bydiagenesis, was used to improve the identification. The proteomic characterization of animal materialsused for clothing production in the Nuulliit archaeological context provides an insight into thepractical knowledge and the strategies adopted by the local Indigenous community to exploit naturalresources Explore
