A1 - Hahn, Oliver T1 - Non-invasive Identifizierung von Pigmenten in modernen Hinterglasbildern (1905-1955) - Highlights aus der Hinterglasforschung N2 - Im Rahmen des Projektes „Hinterglasmalerei als Technik der Klassischen Moderne von 1905 – 1955“, welches vom Museum Penzberg – Sammlung Campendonk, Penzberg (Gisela Geiger und Diana Oesterle) geleitet wurde und in Zusammenarbeit mit der freischaffenden Restauratorin Simone Bretz, der Bundesanstalt für Materialforschung und -prüfung (BAM) und dem Doerner Institut erfolgte, konnte im Rahmen einer Promotion erstmals ein Konvolut von mehr als 60 Hinterglasbildern mit nicht-invasiven Analysemethoden untersucht werden. Die eingesetzten Verfahren ermöglichten die Identifizierung der Pigmente und eine Klassifizierung der verwendeten Bindemittel. Die materialwissenschaftliche Beschäftigung mit der Hinterglaskunst in ihrer Vielfalt ist ein relativ junges Forschungsfeld. Lange wurde ihr mit Unkenntnis, Missverständnis und sogar Geringschätzung begegnet. Im kunsthistorischen Kontext wurde diese Art der Kaltmalerei zumeist mit dem Begriff der Glasmalerei belegt und nicht als eigenständige Kunstform anerkannt, da in beiden Fällen Glas als Bildträger seinen Einsatz findet. In der Hinterglasmalerei wird die Tafelrückseite mit organisch gebundenen Malfarben verziert und das Werk ausschließlich bei auffallendem Licht betrachtet. Die künstlerische Herausforderung liegt immer in der technischen Notwendigkeit eines umgekehrten Malvorganges: die oberste, durch das Glas sichtbare Schicht muss zuerst auf den Bildträger Glas aufgetragen werden, der optische Hintergrund wird zuletzt aufgebracht. Im Vergleich zum Tafelbild, bei dem die Malerei erst durch den Firnisauftrag Tiefenlicht erhält, entfalten die Farben in der Hinterglasmalerei bereits beim Malen ihre Intensität und erhalten gleichzeitig Schutz durch den gläsernen Bildträger (Bretz et al. 2016). Neben der kunstgeschichtlichen und kunsttechnologischen Bearbeitung der Hinterglasbilder spielten materialwissenschaftliche Untersuchungen an einer Auswahl von 66 Bildern im Rahmen des von der VolkswagenStiftung finanzierten Forschungsprojektes eine zentrale Rolle. Grundsätzlich wurde ein nicht-invasiver Ansatz gewählt, um die fragilen Kunstwerke in-situ zu messen und somit einen Transport zu vermeiden. Die Methodik umfasst neben VIS-Spektrometrie in Reflexion und energiedispersiver Röntgenfluoreszenzanalyse (RFA) auch Infrarotspektroskopie in diffuser Reflexion (DRIFTS) und Raman-Spektroskopie. Mit Hilfe des gewählten methodischen Ansatzes lassen sich sowohl anorganische als auch organische Pigmente identifizieren und die Zusammensetzung von Metallfarben und Folien sowie die Glaszusammensetzung qualitativ bestimmen. Ferner ermöglicht die DRIFT-Spektroskopie eine Klassifizierung der Bindemittel. Die im Rahmen des Forschungsprojektes analysierten Hinterglasbilder können folgendermaßen chronologisch gruppiert werden: 1910-1919 (17 Bilder), 1920-1929 (18 Bilder), 1930-1939 (6 Bilder), 1940-1949 (7 Bilder), 1950-1955 (13 Bilder) und >1955 (5 Bilder). Die Auswertung der Ergebnisse ermöglicht grundsätzliche Aussagen über die verwendeten Malmaterialien in Hinterglasbildern in der ersten Hälfte des 20. Jahrhunderts und zeigt Änderungen der verwendeten Pigmente im zeitlichen Kontext auf. Während der ersten Hälfte des 20. Jahrhunderts kamen viele neue Pigmente und Malmaterialien auf den Markt, wobei speziell die synthetischen organischen Pigmente (SOP) zu nennen sind. Eine Vielzahl an SOP konnte in Hinterglasbildern aus allen Zeitgruppen identifiziert werden, wobei hier vor allem Farblacke aus synthetischem Alizarin (PR83), Vertreter der roten und orangen β-Naphthol Pigmente [(z.B. PR3, PR4, PO5 (in Nächtliche Fahrt, 1921 von L. Hildebrandt nachgewiesen)], die blauen und grünen Kupferphthalocyanine [z.B. PG7, PB15 (taucht ab 1949 in Hinterglasbildern auf)] und einige gelbe Azopigmente [z.B. PY1, PY3, PY12 (in Geneigter Mädchenkopf, 1941 von Oskar Schlemmer gefunden)] aufzuführen sind (Steger et al. 2018; Steger et al. 2019a). Einige seltene SOP der Triarylcarboniumgruppe konnten ebenso nachgewiesen werden. Darunter fallen neben der Identifizierung von PR81 (Ohne Titel, 1954, M. Uhlenhuth) auch die erstmaligen Nachweise von PV2 (Hahn, um 1945, L.-G. Buchheim) und PG1 (Exzellente und einmalige Dressuren, 1945/46, L.-G. Buchheim) in Kunstwerken überhaupt (Steger et al. 2018; Steger et al. 2019a). Ferner konnten mit PB52 aus der Gruppe der Anthrachinone und PR60 aus der Gruppe der verlackten Naphthalin-Sulfonsäure-Pigmente weitere seltene SOP in den Bildern Rudern (um 1912) beziehungsweise Apokalyptischer Reiter II (1914) von Wassily Kandinsky nachgewiesen werden (Steger et al. 2019b). Neben den Entwicklungen der SOP können auch eindeutige Trends in den anorganischen Pigmenten veranschaulicht werden. Seltene anorganische Pigmente wie zum Beispiel Strontiumweiß (SrSO4) in der Kreuzabnahme (1914/15) von Carlo Mense (Steger et al. 2019c) wurden identifiziert. Neu entwickelte anorganische Pigmente wie zum Beispiel Cadmiumrot (Cd(S,Se); ab 1928 in 11 Hinterglasbildern nachgewiesen) oder Titanweiß (TiO2; Anatas kommt ab 1922 vor, Rutil konnte nur in Kissen der Träume, 1976 von Werner Schriefers identifiziert werden) tauchen in einigen Hinterglasbildern auf. Schweinfurter Grün (3Cu(AsO2)2·Cu(CH3COO)2) oder Strontiumgelb (SrCrO4) wurden in einigen Bildern bis etwa um 1925 gefunden; diese Pigmente konnten dagegen in späteren Bildern nicht mehr nachgewiesen werden. Als Beispiel sind hier vier frühe Hinterglasbilder (1909–1914) von Wassily Kandinsky zu nennen, wobei Strontiumgelb in vielen Bildpartien zu finden war (Steger et al. 2019b). Publizierte materialwissenschaftliche Ergebnisse von Kandinskys Leinwandgemälden aus späteren Werksperioden zeigen, dass Strontiumgelb zu dieser Zeit vollkommen aus seiner Palette verschwunden ist und vor allem durch ein anderes Gelbpigment, nämlich Cadmiumgelb, ersetzt wurde (McMillan et al. 2013). Eine materialtechnische Besonderheit in der Hinterglaskunst ist die Verwendung von Metallfolien und Metalleffektpigmenten. Metallfolien aus Silber, Zinn, Aluminium oder Messing wurden vielfach als künstlerisches Element in die Komposition integriert, wobei sie als finale Schicht auf, die bereits gestaltete, leicht transparente Malerei geklebt wurden. Durch die Betrachtung im auffallenden Licht erzeugten die Folien bemerkenswerte Glitzereffekte. Zinn- und Aluminiumfolien wurden zum Beispiel in Rudern (um 1912, W. Kandinsky) nachgewiesen, während Messingfolien häufig in Bildern von L.-G. Buchheim gefunden wurden. Die Zinnfolien wurden im 19. und frühen 20. Jahrhundert für Verpackungszwecke (z.B. Zigaretten, Schokolade) verwendet. Aluminiumfolie wurde erst ab 1910 industriell in der Schweiz hergestellt und zu Beginn vor allem für Schokoladenverpackungen eingesetzt (Skrabec 2016). Die frühe Verwendung solche Folien in Hinterglasbildern (z.B. Rudern, um 1912) zeigen eine rasche Verbreitung dieses Materials bei den Künstlern an. Unter Metalleffektpigmenten versteht man feingemahlene Pulver aus Metall (z.B. Zinn, Nickel, Kupfer) und Legierungen (z.B. Messing, Neusilber) mit unterschiedlichen Tönungen, welche bei seitlichem Lichteinfall auf Hinterglasbildern ein merkbares Funkeln erzeugen. Solche Metalleffektpigmente wurden vielfach bei Werken von Heinrich Campendonk nachgewiesen (Geiger und Bretz 2017) und konnten in allen chronologischen Gruppen gefunden werden. Grundsätzlich ermöglichen die Ergebnisse ein besseres Verständnis für die Technik der Hinterglasmalerei und helfen insbesondere, diese eigenständige Kunst im Hinblick auf die „klassische“ Tafel- bzw. Leinwandmalerei abzugrenzen. So zeigen Vergleiche mit Gemälden auf Leinwand von Wassily Kandinsky deutliche Unterschiede in den verwendeten Farbmitteln für beide Techniken. Die Anzahl von 66 gemessenen Hinterglasbildern von 39 Künstlern erscheint im Kontext von über 1200 Arbeiten, welche im Rahmen des Projektes lokalisiert werden konnten, gering. Allerdings können die durchgeführten Untersuchungen als Startpunkt für zukünftige Projekte in diesem Forschungsfeld, beispielsweise für einzelne Werkkomplexe verstanden werden. Die Forschungsergebnisse werden auf die Webseite www.hinterglas-klassischemoderne.de eingestellt. Im Sommer 2020 präsentiert das Museum Penzberg – Sammlung Campendonk Hinterglasbilder von 1910 bis 1960 als Abschlussausstellung des Forschungsprojektes. Die Ausstellung wird von einem ausführlichen Katalog über die fächerübergreifende Forschung begleitet. Für Herbst 2020 ist ein Hinterglas-Symposium an der Bundesanstalt für Materialforschung und -prüfung (BAM) Berlin im Rahmen eines N.i.Ke. Workshops geplant.

It consists of a primary reflectographic screening to determine the type of the ink (soot, tannin or iron-gall) and a subsequent in-depth analysis using several spectroscopic techniques: X-ray fluorescence (XRF), Infrared and Raman spectroscopies. The first of them, XRF elemental analysis aims at establishing the unique fingerprints of inks containing metals or trace elements in carbon inks. In addition, we use Raman analysis to identify so-called mixed inks, an ink category that received little attention so far. Finally, with the help of IR spectroscopy we obtain information about the ink binders. T2 - Coptic Literature in Context.

This presentation will examine the inks used by Jews in the in different geographical zones try to correlate the results of the material analysis with written records and existing traditions. We will compare the inks proposed by Maimonides, who lived in 12th-century Egypt, with the considerations of Rashi, who lived in 11th-century northern France, and see that they both advocated use of the inks commonly known and produced in their respective regions. It is Maimonides who proposes to add tannins to the soot inks, but rejects the metallic salt, both of which were practices that were well attested in contemporary Arabic recipes for making ink. In contrast, Rashi was favourable to employing the plant inks in use in contemporary Northern Europe.

The success of their contribution depends strongly on the formulation of the question and the choice of the methods to obtain the requested answer. Therefore, one should try to go beyond the understanding of the basic principles of the scientific analysis. We will start with a glance at the basic principles of the techniques used in the material science for determination of the elemental composition (X-ray emission) and molecular composition (FTIR & Raman). We will move then to the bench and mobile equipment commonly used in the field of cultural heritage. At the end we will choose a question to be answered and design an ideal experiment that will be modified according to the limitations dictated by on-site conditions. In the ateliers in the afternoon we will a) compare two XRF devices that differ in their spatial resolution; b) use a high resolution microscope (Keyence) to obtain a close look at writing surfaces and materials; c) we will learn to determine the type of the inks with the help of another microscope (DinoLite AD413T-12V), a usb microscope with visible, UV and NIR illumination; d) we will learn to use FTIR-ATR device for determination of the type of the writing surface; e) We will use mobile Raman device for identification of pigments.

Our studies of the Dead Sea Scrolls writing surfaces show that they can be divided roughly into three groups: leather, parchments of a light tint, and those of various shades of brown. The latter ones are invariably tanned, whereas the middle group is characterized by the presence of various inorganic salts. Some of the pale parchments, among them the Temple Scroll (11Q19), are remarkably similar to medieval European parchment. Therefore we have formulated the working theory that in the Judaea of the Hellenistic period two different parchment-making traditions existed side by side: an ‘eastern’ one (represented by the tanned parchments of Qumran, closely resembling Aramaic documents from the fifth century BC, and a ‘western’ one (represented by the untanned/lightly tanned ones similar to early Christian Greek parchments). This division has found support during our studies of the Geniza fragments, in which Babylonian and Palestinian traditions seem to follow the “eastern” and “western” technologies, respectively.

The first comprises materials that write themselves, producing script by rubbing their own material off onto the writing surface. It includes charcoal, graphite, chalk, raddle, and metal styluses. Depending on the material and consistency, these are cut or pressed to make styluses and then used for writing. The second group comprises all coloring liquids that are applied to the writing surface with a quill, pen, or printing block. It includes inks made from dye solutions (for example, tannin inks) and those made from pigment dispersions (for example, sepia, soot, and bister inks). The latter are sometimes also rubbed as pastes into letters incised into the writing surface, where they increase visual contrast. Due to the variety of recipes and the natural origin of raw materials, there is a wide range of different components and impurities in writing materials. Soluble inks (Tinten) Soluble inks are based mainly on dyes forming a water solution. Colored inks were manufactured with different plant or insect dyes (e.g. Brazil wood, kermes). To stabilize the volatile material, the dyes were mixed with a mordant (e.g., alum). Brown plant inks – best-known as blackthorn or Theophilus’ inks – are usually produced from the blackthorn bark and wine. In the early European Middle Ages, inks of this kind were widely used in the production of manuscripts in monasteries. Usually, they are light brown, so sometimes small amounts of iron sulfate were added, which led to what was called an “imperfect” iron gall ink. The difference between “classic” iron gall ink and such imperfect ink is therefore not clear: the distinction is not possible, especially with the naked eye. Dispersion inks (Tuschen) According to its generic recipe, one of the oldest black writing materials is produced by mixing soot with a binder dissolved in a small amount of water. Thus, along with soot, binders such as gum arabic (ancient Egypt) or animal glue (China) are among the main components of soot inks. From Pliny’s detailed account of the manufacture of various soot-based inks, we learn that, despite its seeming simplicity, producing pure soot of high quality was not an easy task in Antiquity. Therefore, we expect to find various detectable additives that might be indicative of the time and place of production. One such carbon ink requires the addition of copper sulfate . The experimental discovery of this ink in 1990 led to a misleading expression “metal ink” that is sometimes found in the literature. Colored dispersion inks based on pigments such as orpiment, cinnabar, or azurite have been known since Antiquity. Natural or artificially produced minerals are finely ground and dispersed in a binding medium. As in soot inks, water-soluble binders such as gum arabic or egg white were used. Iron gall ink (Eisengallustinten) Iron gall inks are a borderline case between these two groups. They are produced from four basic ingredients: galls, vitriol as the main source of iron, gum arabic as a binding media, and an aqueous medium such as wine, beer, or vinegar. By mixing gallic acid with iron sulfate, a water-soluble ferrous gallate complex is formed; this product belongs to the type “soluble inks”. Due to its solubility, the ink penetrates the writing support’s surface, making it difficult to erase. Exposure to oxygen leads to the formation of insoluble black ferric gallate pigment, i.e., “dispersion ink”. Natural vitriol consists of a varying mixture of metal sulfates. Since for ink making it was obtained from different mines and by various techniques, inks contain many other metals, like copper, aluminum, zinc, and manganese, in addition to the iron sulfate. These metals do not contribute to color formation in the ink solution, but possibly change the chemical properties of the inks.

A1 - Targowski, P. A1 - Rabin, Ira T1 - What should we take into an account in the characterization of iron-gall ink by means of X-ray fluorescence? N2 - The earliest known recipes for iron gall inks include four basic ingredients: oak galls – pathological growths of oak leaves; metal salts – usually referred to as vitriol; a binder such as gum Arabic; and water. The final product differs in the elemental composition due to the multitude of recipes as well as differences within the composition of the ink’s ingredients. Nowadays, based on the qualitative and semi-quantitative evaluation of X-ray fluorescence data, it is possible to distinguish inks on the basis of the so-called fingerprint model. The first goal of our study was to determine to what extent the type of XRF spectrometer affects the quality of the ink evaluation. We tested two types of spectrometers, semi-stationary machines equipped with polycapillary focusing optics and a handheld spectrometer with a diaphragm collimator and a relatively big interaction spot. The second goal was to address the issue of whether the ink composition might be affected by storage in a metal container. The presentation will discuss the role of the spectrometer type in the evaluation of a thin layer material such as ink. We have also learned that the iron-gall ink composition might depend on the type of vessel in which ink was being stored.

The focus here is on drawings that were executed with red chalk. This drawing material has different functions - one of which is the use as a transmission material. The methodological approach is double: first, the scientific indexing of this stock. The foundations for this, along with classic analysis of style, are innovative material-scientific methods of investigation. T2 - Red Chalk Drawings.

Exhibit display cases should protect cultural objects from dust as well as from mechanical and physical damage. To ensure a stable climate inside the display cases, a low air exchange rate is maintained. Typically air exchange rates are often smaller than 0.1 d 1, which can result in rising concentrations of potential harmful immissions inside of the display cases due to emissions from materials. Especially high concentrations of organic acids, which can emit from e.g. sealing materials, can produce damage of cultural objects. In 2012 BAM introduced a procedure witch is called: BEMMA-Scheme (Bewertung von Emissionen aus Materialien für Museumsausstattungen) which stands for: “Assessment of Emissions from Materials for Museum Equipment”. Micro chambers are used for VOC emission tests of display case construction materials, e.g. textiles, plastics, sealing material, coatings and others. Each sampling procedure is carried out in duplicate. Emissions like formic acid, acetic acid, formaldehyde and oximes are excluded and the sum of emissions of VVOCs, VOCs and SVOCs is limited. For a positive assessment all listed criteria must be fulfilled; otherwise the display construction material fails the BEMMA scheme. The BEMMA scheme is not a guarantee for an emission free display case, but a necessary requirement for the choice of suitable materials for emission and immission reduced display cases.

Though technological progress considerably affected each step of the manufacture of paper, the essence of the invention remains unchanged until today. The process of manufacturing handmade paper can be divided into a number of steps: - choosing the raw material (e.g. cellulose from wood, cotton, rags) - beating and grinding the fibres into small pieces - producing a liquid pulp of the desired texture - treating the pulp with various additives - filling the pulp suspension into a paper mould - draining the water - pressing and drying to get the actual sheet - various post-production treatments We will see how the manufacturing process is reflected in the properties of the paper and its degradation. A special attention will be paid to the instrumental analysis for identification of the paper types. Also watermark play an important role in the studies of the manuscripts. A short overview will be offered at the ends of the lecture.

T1 - Analyses of paper, tinting and illumination in persian manuscripts held in the Golestan Palace library N2 - In the 15th century, Persian manuscripts underwent significant and lasting changes. Possibly as a response to the import of tinted and gold-decorated paper from China, which was used for manuscript production in Greater Iran, Persian papers were also tinted and embellished with gold-decorated and marbled margins or frames. In a joint project between CSMC and the University of St Andrews, and in co-operation with the Golestan Palace Museum, we aim to analyse papers and their decorations in manuscripts in the holdings of the Golestan Palace Library. The analyses aim to determine the consistencies of papers, pigments and metals and the techniques used for their production and application. The support will be first described in its codicological characteristics such as dimensions, thickness, colour (expressed in colour coordinates), pattern left from the sieve (observed in transmitted light). The plant used as raw material in paper production will be studied by fibres analysis, while the sizing agents, the pigments, dyes and metals will be analysed by the application of several methods: in particular Reflectography, X-Ray Fluorescence and InfraRed, Raman and Visible Reflectance Spectroscopy. The results of the analyses will be published in an online database that will form an important resource for the material aspects of Persian manuscripts and be a starting point for establishing a first chronology of the materials and techniques used in Persian manuscript production.

But papyrus was also burnt in order to obtain soot used as an ingredient for a particular type of ink (midād al-qarāṭīs). In this talk I will give an overview of the recipes – in particular those by ar-Rāzī –, their context and transmission in order to evaluate this double nature of papyrus, which is considered at the same time a writing support and a material to be recycled. Moreover, I will discuss what kinds of ink are most likely to be found, according to these literary sources, on Arabic manuscripts and documents written on papyrus and compare them to the typologies mentioned for paper and parchment. These results are the premises of a research project starting at the beginning of 2019, in which a number of dated fragments from several European institutions will be analysed with non-destructive techniques in order to establish a profile of the main writing media used in the early centuries of the Islamic Era.

For this reason (among others) in the last 50 years analytical techniques have been applied to the study of manuscripts. Unfortunately, the scientific investigation of Arabic books is still uncommon, focusing mainly on single case studies of illuminated manuscripts where the black media used to write the text is largely overlooked. This lack of knowledge prompted a recent research in which black ink recipes have been collected from written Arabic sources, their feasibility has been assessed, and some of them have been reproduced. These samples were artificially aged and analysed through an array of analytical techniques, mostly non-invasive and non-destructive, in order to build a database of Arabic inks and their ingredients and to verify the detection limits of the equipment employed. Finally, the results were compared to the data collected from historical manuscripts. In this talk I will focus on the ink typologies and the terminology (ancient and modern) used to describe them. In particular I will highlight how even the modern classification fails to capture the variety encountered in both recipes and manuscripts, particularly in the light of recent discoveries. I will address especially the terminological and conceptual issues of mixed inks – in the form of carbon inks and tannins, of carbon and iron gall inks, and of carbon and metallic salts –, iron gall inks made without vitriol and iron gall inks made with sources of tannins different from gall nuts.

They may be included in treatises of diverse subjects – from handbooks for secretaries or calligraphers to books on arts and crafts, to alchemical and astrological essays. Recipes can also appear, with or without relation to the main text in the manuscript, in the form of lists or collections or even added in empty spaces as single entries. Why were these recipes written down? Were they used by the many professionals dealing with inks in their every-day work? Or were they part of the literary genre of adab with little or no practical application? To answer these questions a research project was set up: ink recipes have been collected from written Arabic sources, their feasibility has been assessed and some of them have been reproduced. These samples were artificially aged and analysed through an array of analytical techniques, most non-invasive and non-destructive, and the results compared to the data obtained by the application of the same analyses on concrete manuscripts. The codicological characteristics of the manuscripts have also been studied. My aim in this talk is to show how such an interdisciplinary approach could be beneficial for the study of material culture.

In the first part I will present the analytical techniques and the equipment used by the Centre for the Study of Manuscript Cultures that can be applied for the study of decorated papers. The analyses aim to determine the constituent materials of papers, pigments, dyes and metals and the techniques used for their production. I will focus in particular on the kind of information these techniques allow us to gather: through optical microscopy we conduct fibre analysis in order to identify the plant used as raw material in paper production while Reflectography, X-Ray Fluorescence and InfraRed, Raman and Visible Reflectance Spectroscopy are used to study the sizing agents, the pigments, dyes and metals. In the second part I will show some results obtained by the application of these techniques on a few Persianate manuscripts, dating between the 15th and 17th centuries, belonging to the corpus of Ilse Sturkenboom.

Unfortunately, the scientific investigation of Arabic books is still uncommon, focusing mainly on single case studies, often producing unclear results, especially for black inks. This lack of knowledge prompted a recent research in which black ink recipes have been collected from written Arabic sources on bookmaking, their feasibility has been assessed, and finally some of them have been reproduced. These samples were artificially aged and analysed through an array of analytical techniques, mostly non-invasive and non-destructive, in order to build a database of Arabic inks and their ingredients and also to verify the detection limits of the portable equipment employed. In this talk I will present some instances of how this approach can help textual criticism, for example in evaluating variants and determining the competence of authors and compilers. At the same time the research highlights how much this scientific work depends on textual studies, especially concerning the identification of ingredients. Moreover, I will focus on some of the problematics I faced both during the textual interpretation and the actual reproduction of the recipes and how they influenced the results of the scientific analyses. In particular I’ll look into the role played by the degree of purity of the components and the function (real and perceived) of some of the ingredients.

A1 - Rabin, Ira T1 - XRF ink analysis of selected fragments from the Herculaneum collection N2 - Hundreds of papyrus rolls, carbonized during the 79CE eruption of Mount Vesuvius, were discovered in 1754 at Herculaneum. Sophisticated mechanical methods for unrolling the best-preserved scrolls have been applied, with varying success. However, such processes have been abandoned, to prevent risk from irremediable damage or loss and to preserve the integrity of the extremely fragile rolls. Following the development of X-ray based non-invasive techniques, attempts to virtually unroll the scrolls were made. The most common ink in Antiquity was carbon-based, and the main element of carbonized papyrus is carbon, making these investigations difficult. However, some attempts with synchrotron X-ray phase-contrast tomography (XPCT) were successful. Recently, the identification of antique inks containing metals raised hope that if some of the inks contain metal the rolls can be virtually unrolled using conventional CT- technique. We are presenting here the first results of a preliminary analysis, which aimed at identifying scrolls whose ink contains metals.

In collaboration with the other two service projects, Z01 and Z03, it aims at bridging the gap between humanities and natural sciences and technology. To that purpose, we set up a laboratory with a range of high-end instruments, most of them mobile, allowing thorough non-destructive analysis of manuscripts. In addition to working on constantly improving the laboratory and the methods of analysis, a substantial part of our activities is dedicated to service, by supporting different research projects conducted at the centre. In this talk, we will present our equipment and the possibilities offered by the different techniques available regarding the different kinds of missions: typology and classification of inks, provenance studies, recovery of faded inscriptions and palimpsests, reconstruction of the history of manuscripts, authentication and dating. We will give a brief overview of our past and ongoing activities in the frame of the second phase of the CSMC. Finally, a selection of three projects will be presented in greater detail to highlight the possibilities of our laboratory and the diversity of missions which can be carried out.
