Pigment-Macromolecule Complexes Isolation from Sea Urchin Biomineral Waste for Coloring Materials Claudio Ferreira, Vaskar Sardhalia, Alshaba Kakar, Romain Descamps, Lucrèce Matheron, François Ribot, Alexandre Disser, Tony Jouanneau, Elena Vasileva, Natalia Mishchenko, Nadine Nassif, Frédéric Marin, Marie Albéric Chemistry Methods, 2026 The production and widespread use of synthetic pigments and dyes have significant environmental and health impacts. Despite this, synthetic colorants remain dominant due to their wide color range, high stability, strong tinting power, and lower cost compared to natural alternatives. Therefore, to offer sustainable and competitive substitutes, eco‐friendly methods for producing bio‐based pigments with similar performance are essential. Herein, a methodology has been developed to extract the entire colored organic fraction occluded within seashell biomineral waste, which comprises pigments and pigment‐macromolecule complexes. This process involves an optimized cleaning procedure of the biomineral soft tissues, a tailored biochemical extraction, and detailed characterization of the extracted fraction. Applied to sea urchin skeletons, this method successfully isolates polyhydroxylated naphthoquinone (PHNQ)‐macromolecule complexes. These complexes show superior pH stability in purple hues compared to free PHNQ, which shifts from red to purple in basic conditions. Notably, the approach enhances colorant yield by up to five times. These results, together with mineral pigment synthesis and fabric dyeing assays performed with the extracted colored organic fraction, contribute to a better understanding of the origin of color in biominerals and reveal the versatility of these natural pigments for environmentally friendly coloring of both organic and inorganic materials.
Multi-classifier majority voting analyses in provenance studies on iron artefacts Grzegorz Żabiński, Jarosław Gramacki, Artur Gramacki, Ewelina Miśta-Jakubowska, Thomas Birch, Alexandre Disser Journal of Archaeological Science, 2020 The main objective of this paper is to propose an approach for identification of provenance of archaeological iron artefacts making use of major oxides and trace elements. For this purpose, seven classifiers were built on the basis of the following techniques: Linear Discriminant Analysis (LDA), Support Vector Machine (SVM), Random Forests (RF), Naïve Bayes (NB), K-Nearest Neighbours (KNN), Recursive Partitioning and Regression Trees (RPART) and Kernel Discriminant Analysis (KDA). A final assignment of a given observation to a regional class was carried out on the basis of results provided by all classifiers using a majority voting technique. The proposed approach was first tested on experimental slag and then it was applied to actual archaeological data. It is hoped that this method can become part of a new integrated approach which will consider all available types of data, such as major and trace elements and isotopic ratios.
A 15th century ear-dagger and its scabbard from the found at castel-minier (French pyrenees) Florian Téreygeol, Alexandre Disser, Julien Flament, Guillaume Sarah Gladius, 2019 [fr] Il est peu commun de mettre au jour de l’armement dans un contexte archéologique minier. La découverte faite à Castel-Minier est d’autant plus importante qu’elle est intervenue dans un contexte archéologique maitrisé. Elle met en lumière une dague à oreilles de la fin du XVe siècle qui diffère largement de celles connues dans les collections par sa sobriété. C’est la première fois que cet équipement offensif est découvert en contexte archéologique. Au-delà de la raison d’être de ce poignard dans une mine d’argent au XVe siècle, son étude permet de mettre en lumière pour la première fois une dague à oreilles de facture catalane destinée à un marché bien différent de celui des exemplaires connus dans la bibliographie.
‘Guard the Good Deposit’: Technology, Provenance and Dating of Bipyramidal Iron Semi-Products of the Durrenentzen Deposit (Haut-Rhin, France) S. Bauvais, M. Berranger, M. Boukezzoula, S. Leroy, A. Disser, E. Vega, M. Aubert, P. Dillmann, P. Fluzin Archaeometry, 2018 In the early days of iron metallurgy in Western Europe, the most widespread type of ‘trade iron’ (semi-product) was bipyramidal in shape. Although they are frequently found, little is known about how they were manufactured and circulated, or even about their age. An interdisciplinary approach was applied to the Durrenentzen deposit (Haut-Rhin, France), the third-largest in Europe in terms of artefact quantities, in an attempt to reconstruct the technological, social and economic context that caused them to be abandoned. A morphometric study of the 51 iron bars revealed a high degree of homogeneity, despite variations in detail. Four objects were selected for archaeometric studies. Metallographic analyses show internal differences (quality of the material, nature of the alloys and manufacturing techniques). Chemical analyses also showed different provenances. Finally, radiocarbon analyses of the carbon in steel (iron/carbon alloy) linked this deposit to the early Iron Age. This study provided the first benchmark for more general research, significantly changing perceptions of the economics of iron at the beginning of the Iron Age.
Iron Supply for the Building of Metz Cathedral: New Methodological Development for Provenance Studies and Historical Considerations A. Disser, PH. Dillmann, M. Leroy, M. L'Héritier, S. Bauvais, PH. Fluzin Archaeometry, 2017 This paper develops new reflections regarding the provenance of iron artefacts, by defining the trade networks that might have supplied the building yard of the Metz city belfry at the end of the 15th century. Regional field surveys were carried out in Lorraine in order to constitute a chemical repository, including ironmaking zones considered as the most probable metal providers. The chemical characterization—both major and trace elements—of slag inclusions entrapped in the metallic matrix of iron reinforcements was performed in order to compare their chemical signature to the reference set. A statistical approach based on the combined use of descriptive multivariate analyses was developed to infer the origin of the metal supplied to the building yard. As the multiplicity of potential metal providers was assessed from former studies, the results obtained underline the place taken by local workshops in the supply strategy developed by the builders. This study thus provides crucial information supporting a discussion about the scale and the organization of such networks at the end of the Middle Ages
