TY - CHAP A1 - Ghigo, Tea A1 - Torallas, S. T1 - Between Literary and Documentary Practices: The Montserrat Codex Miscellaneus (Inv. Nos. 126‐178, 292, 338) and the Material Investigation of Its Inks N2 - The Montserrat Codex Miscellaneus (TM 59453/LDAB 552) has been the subject of numerous studies since the publication of ist first text by its owner, father Ramon Roca-Puig. Scholars have dealt with the content of its texts, as well as interrogated its origin and materiality. It is a fourth-century papyrus single quire codex, which contains texts in both Latin and Greek. It has been argued that it belonged to the Bodmer library, connected to a Pachomian library in the Thebaid. In this paper we want to contribute to the material study of the codex by presenting the first results of an archaeometric analysis performed upon the inks. The Analysis was carried out within the framework of the ‘PAThs’ project based at Sapienza University of Rome, and executed with the close cooperation of DVCTVS, a team of scholars who curate the Roca-Puig collection. The results obtained have not only cast light on the history of production of the codex, but also, and perhaps most importantly, point out that a meaningful interpretation of the analytical data is only possible through an interdisciplinary collaboration between the humanities and the natural sciences.

These results can be set in a historical context and help to confirm art historical interpretations. Proofs of certain pigments can be used for dating purposes and may reveal if the artist used not only local but also imported materials. A pilot study of two Chinese reverse glass paintings from the late 19th (Yingying and Hongniang) and early 20th centuries (The Archer) was performed using a multi-analytical approach including X-ray fluorescence (XRF), diffuse reflectance infrared Fourier transform spectroscopy (DRIFTS) and Raman spectroscopy. This approach allowed the identification of the pigments and the classification of the binding media. The results reveal a combined use of traditional Chinese and imported European materials. Several pigments like cinnabar, lead white, orpiment, carbon black and copper-arsenic green (probably emerald green) were found in both paintings; red lead, artificial ultramarine blue, Prussian blue and ochre appear in at least one of the paintings. The proof of limewash (calcite and small amounts of portlandite) as a backing layer in “Yingying and Hongniang” indicates that clamshell white was also used for reverse glass paintings. Drying oil was classified as a binding media in most areas of both paintings. However, the orange background of The Archer yielded prominent bands of both proteinaceous and fatty binder.

T1 - La invencíon del Sacromonte: How and Why Scholars Debated about the Lead Books of Granada for Two Hundred Years N2 - At the end of the sixteenth century, a number of relics and artefacts were discovered in Granada, Spain. They included what became known as the Lead Books of the Sacromonte, twenty-one written artefacts made of circular lead leaves engraved in archaic Arabic characters. The authorship was attributed to some Arab disciples of St James the Greater considered to be the first evangelisers of the Iberian Peninsula. The texts, the materiality and the circumstances of the discoveries fuelled a debate surrounding their authenticity that lasted more than two centuries, a debate so fierce and controversial that not even papal condemnation in 1682 was able to stop it. Soon after the discoveries were made public, scholars highlighted the many contradictions and errors of a historical, linguistic and theological nature present in the texts, identifying members of the local Morisco community as possible forgers. This article focuses on how the scholarly community of the sixteenth and seventeenth centuries handled these findings and looks at the methods employed by the scholars to evaluate the authenticity of the artefacts. It will also look at how the particular interests of the various authorities involved influenced the acceptance or dismissal of relevant academic results.

Weit verbreitet ist mittlerweile die „Fused Filament Fabrication (FFF)“ Technologie. Hier wird ein thermoplastisches Filament geschmolzen, durch eine Metalldüse extrudiert und anschließend schichtweise so auf ein Druckbett aufgetragen, dass ein 3D-Objekt entsteht. Das Filamentmaterial wird dabei thermisch stark belastet, was zur Emission von Aerosolen sowie flüchtigen organischen Verbindungen (VOC) führt. Dabei werden hauptsächlich ultrafeine Partikel (UFP, dP < 100 nm) freigesetzt werden, die sogar in manchen Fällen im sub-4nm Größenbereich einen signifikanten Anteil ausmachen können (Tang und Seeger 2024). Die gesundheitliche Relevanz eingeatmeter UFP ist durch sehr viele Studien gut belegt. Während eines i.d.R. mehrstündigen FFF-Druckvorgangs wird ein Anwender mit diesen Luftschadstoffen im Innenraum exponiert, häufig ohne eine Einschätzung des damit verbundenen Risikos zu haben. Die Exposition kann durch technische Faktoren (z.B. Druckerausstattung und -einstellung, Innenraumventilation), aber auch erheblich durch die Filamentauswahl beeinflusst werden. Unser Vorschlag zur Risikominderung besteht in der Auszeichnung emissionsarmer Filamentprodukte mit dem Umweltzeichen „Blauer Engel“, um so den Verbrauchern eine fundierte Auswahl zu ermöglichen. In unserem Projekt entwickeln wir dafür ein kammerbasiertes, standardisierbares und robustes Prüfverfahren zur vergleichenden Messung der Emission aus Filamenten. Mit dem Strangdruck-Verfahren (engl. Strand Printing Method, SPM) wird eine festgelegte Filamentlänge mit konstanter Rate extrudiert und auf dem Druckbett abgelegt, ohne dabei ein 3D-Objekt aufzubauen. Diese Vorgehensweise reduziert den Einfluss experimentell schlecht zu kontrollierender Faktoren sowie die Ausfallquote. Eine detaillierte Beschreibung und die Vorteile von SPM werden in Tang und Seeger (2022) erläutert. SPM wurde bereits für 44 Filamentprodukte aus unterschiedlichen Polymeren und Additiven als Vergleichstest angewendet. Alle Messungen wurden in einer klimatisierten 1 m³-Emissionsprüfkammer durchgeführt. Die Gesamtanzahl der emittierten Partikel (TP) dient als Beurteilungsmaß, in Anlehnung an die Vergabegrundlage DE-UZ-219 des Umweltzeichens Blauer Engel für Laserdrucker. Unter den getesteten Filamentprodukten variiert TP um ca. vier Größenordnungen (1E+9 ≤ TP ≤ 1E+13). Auch innerhalb jeder der untersuchten Polymergruppen variierte TP signifikant. Die Partikelemission kann daher nicht allein nach dem Basispolymer kategorisiert werden. Unsere Resultate belegen, dass die Stärke der Partikelemission eher eine charakteristische und individuelle Eigenschaft eines Filamentproduktes ist. Die Herkunft der Polymere, die herstellerspezifischen Additive sowie die nicht deklarierte Verunreinigungen können einen starken Einfluss auf die Emission haben. Die Auszeichnung von emissionsarmen Filament-produkten verspricht somit eine einfache, aber effektive Maßnahme zu sein, um Verbrauchern eine Minderung des Expositionsrisikos beim FFF-3D-Druck zu ermöglichen.

An often-heard argument within a call for tender of new display cases is that there should be no emission inside of the display case. This is nearly impossible for new ones especially when they must also fulfill the requirement of an air change rate of less than 0.1 per day. For example, constructions or decorations in exhibition spaces, storage containers in depot rooms, and exhibition display cases release volatile substances that might lead to irreversible changes or, under certain circumstances, damage to the stored or displayed objects. In Germany beneath the well-established Oddy-test also the BEMMA procedure is used to evaluate the construction materials. For larger amounts of display cases control measurements of VOCs at the end of construction or buildup is quite common. However, what is necessary to measure the air inside of display cases. What are the circumstances when the display cases were closed before the test period? Is it possible to organize a clean environment for reliable measurements. How comparable are the resulting VOCs with results from BEMMA test and control measurement at the end. The BEMMA procedure should include a further VOC-test at 60 °C. What are the benefits of this enlargement. Mainly materials that have a high potential to store VOCs inside of the material in combination with a less permeable surface should be evaluated stricter than others.

Tras las huellas de los aztecas, se ocupa de una colección excepcional de manuscritos mexicanos y sudamericanos. La colección se inició cuando, a principios del siglo XIX, Alexander von Humboldt donó a la Biblioteca Real de Berlín varios fragmentos de manuscritos pictográficos indígenas del siglo XVI procedentes del actual México. Estos documentos, conocidos habitualmente como Fragmentos Humboldt, representan la parte más notable de la colección, que con el tiempo se fue ampliando a través de la adquisición de diferentes manuscritos mesoamericanos, principalmente escritos en lenguas indígenas con caracteres latinos. Entre abril de 2017 y marzo de 2019, la Staatsbibliothek zu Berlin - PK (SBB) y el Bundesanstalt für Materialforschung und -prüfung (BAM) llevaron a cabo un proyecto científico conjunto, financiado generosamente por la Deutsche Forschungsgemeinschaft (DFG) con el nombre de Análisis material y estudios histórico-culturales de manuscritos coloniales mexicanos en Berlín y Cracovia. Los principales objetivos del proyecto fueron determinar la procedencia de los manuscritos americanos y, dado que presentan un alto grado de fragmentación, establecer sus relaciones internas y las que establecen con otros objetos ajenos a la colección. Para ello, se combinaron métodos de análisis de corte etnográfico, cultural e histórico con otros propios de las ciencias naturales. Gracias a la buena cooperación con la Bibliotheka Jagiellońska tuvimos acceso tanto a los Manuscripta americana de Berlín como a los de Cracovia, pudiendo proceder a su examen exhaustivo y realizar exámenes científicos de alta precisión. N2 - Die Publikation befasst sich mit einer einzigartigen Sammlung mexikanischer und südamerikanischer Handschriften, die zu Beginn des 19. Jahrhunderts ins Leben gerufen wurde, als Alexander von Humboldt der Königlichen Bibliothek zu Berlin Fragmente indigener mexikanischer Bilderhandschriften aus dem 16. Jahrhundert schenkte. Sie sind heute auch unter der Bezeichnung Humboldt-Fragmente bekannt und stellen den bedeutendsten Teil der Sammlung dar, die im Laufe der Zeit durch den Ankauf verschiedener Arten von Handschriften aus Mittelamerika, vorwiegend in indigenen Sprachen und lateinischer Schrift, erweitert wurde. In den zwei Jahren von April 2017 bis März 2019 verfolgten die Staatsbibliothek zu Berlin – Preußischer Kulturbesitz (SBB-PK) und die Bundesanstalt für Materialforschung und -prüfung (BAM) ein gemeinsames, von der Deutschen Forschungsgemeinschaft (DFG) großzügig gefördertes wissenschaftliches Projekt: Materialanalysen und kulturgeschichtliche Untersuchungen mexikanischer Handschriften aus der Kolonialzeit in Berlin und Krakau. Die Hauptziele des Projekts bestanden darin, die Provenienz der Manuscripta americana zu ermitteln und, da sie einen hohen Grad an Fragmentierung aufweisen, festzustellen, wie sie untereinander und mit Objekten außerhalb der Sammlung in Beziehung stehen. Zu diesem Zweck wurden ethno-kulturhistorische und naturwissenschaftliche Methoden kombiniert. Dank einer guten Zusammenarbeit mit der Jagiellonen-Bibliothek konnten wir die Manuscripta americana sowohl in Berlin als auch in Krakau sehen und studieren und sie wissenschaftlich vermessen.

The collection was established at the beginning of the 19th century, when Alexander von Humboldt donated fragments of 16th century indigenous Mexican pictorial manuscripts to the Royal Library in Berlin. Today these are also known as the Humboldt fragments and represent the most significant part of a collection that was augmented over the years by the purchase of various types of Mesoamerican manuscripts, mainly in indigenous languages with Latin script. During the two year period from April 2017 to March 2019, the Berlin State Library (SBB - SPK) and the Bundesanstalt für Materialforschung und -prüfung (BAM) carried out a joint scientific project funded by the Deutsche Forschungsgemeinschaft (DFG) entitled "Material-analytical and cultural-historical examinations of colonial-period manuscripts from Mexico in Berlin and Cracow." The main objectives of the project were to determine the provenance of the Manuscripta americana and, since they exhibit a high degree of fragmentation, to examine how they are related to each other and to objects outside the collection. The investigation combined ethnocultural-historical and materials science methods of analysis. Thanks to the constructive partnership with the Jagiellonian Library, we were able to see and study the Manuscripta americana in both Kraków and Berlin and to carry out scientific measurements on them.

A1 - Freisitzer, R. A1 - Rabin, Ira T1 - A study on early european inks from St. Paul in lavanttal N2 - Typology of Inks Archives and museums around the world contain a vast number of manuscripts that were written in different inks: carbon inks, plant inks, iron-gall inks and mixed inks. Yet most archaeometric studies of manuscripts focus on the palette of pigments found in illuminated manuscripts whereas identification of the inks is still largely based on cultural-historical studies and visual inspections. One of the reasons of this disproportion in the studies can be explained by the properties of Raman spectroscopy, the technique of choice for identification of pigments. In contrast, this technique is only partially viable when dealing with organic colourants. Brown and Clark discuss these difficulties and the uncertainties of identification of iron-gall inks by Raman spectroscopy in their pioneering work on early medieval Anglo-Saxon manuscripts (K. Brown and R. Clark 2004). To facilitate instrumental analysis of inks, we have developed a protocol that starts with the identification of the inks type (Rabin et al. 2012) which doesn’t require complicated instrumentation and can be carried out by paleographers and codicologists. Three typological ink classes The black writing materials used in manuscript production in Antiquity und Middle Ages can be sorted in three typologically different ink classes: soot, plant and iron-gall. Soot ink is a fine dispersion of carbon pigments in a water soluble binding agent; plant-based ink consists of a solution of the tannins extracted from gallnuts or tree bark; iron-gall ink, is produced by mixing a soluble compound of iron (II) with gallic or tannic acid extracted from gallnuts or tree bark. Therefore, iron-gall ink presents a boundary case between solution and dispersion ink, in which a water-soluble preliminary stage oxidizes and evolves into a black, insoluble precipitate similar to the carbon pigments when the writing is exposed to air (Krekel 1999). The additional category of mixed inks, i.e. inks produced by addition of various metals to the soot inks or intentional mixing of iron-gall and soot - based inks started attracting scholarly attention only recently because their significance was established only a short while ago (Brun et al. 2016, Colini 2018, Nehring et al. 2021). We suggest that plant and mixed inks build a bridge from the carbon ink of Antiquity to the properly formulated iron-gall ink that became a standard black ink from the late Middle Ages to the 19th century when it gave way to modern inks.

Das Papier besteht aus Fasern meist pflanzlicher Herkunft und wird durch Entwässerung einer Fasersuspension auf einem Sieb gebildet. Der Abdruck des Schöpfsiebes (die Papierstruktur) und ein vorhandenes Wasserzeichen bieten Anhaltspunkte für Provenienz und Datierung; daneben erlaubt die Analyse der Fasern, der Füllstoffe und der Leimung eine weitere Charakterisierung des Schriftträgers. Spätestens seit dem Mittelalter sind es Eisengallustinten, die das schwarze bis bräunliche Erscheinungsbild vieler Manuskripte auf Papier hervorrufen. Daneben lassen sich auch schwarze Rußtuschen oder farbige Auszeichnungstuschen nachweisen. Eisengallustinten werden durch Mischung einer eisenhaltigen Komponente mit Gerbstoffen hergestellt. Eisensulfat ist die am häufigsten genannte Eisen liefernde Zutat, daneben sind aber auch eisenhaltige Minerale, Nägel oder Rost denkbar. Die Gallussäure leitet sich ab aus den Galläpfeln, der krankhaften Veränderung einzelner Planzenteile verschiedener Eichenarten. Diese werden durch die Eiablage von Schlupfwespen hervorgerufen. Wie schon beim Papier ermöglicht der materialanalytische Nachweis charakteristischer Beimischungen oder Verunreinigungen innerhalb der Tinten die Beantwortung kulturhistorischer Fragestellungen – gemeint sind hier die Unterscheidung von Original und Korrektur oder die Sichtbarmachung späterer Ergänzungen.

The challenge imposed by the study of this specific type of manuscript led to designing and building dedicated stages to ensure the safety of the scrolls during the analysis. Furthermore, the identification of multiple corrections executed in apparently identical inks required broadening the standard two-step protocol of near infrared reflectography and X-ray fluorescence to include multispectral imaging. This work has prepared the division to participate in the large collaborative project “To roll: Materialisierte Heiligkeit (Materialised Holiness)” based at the Free University, Berlin.

Soluble inks are based on plant or insect dyes forming a water solution. In the early European Middle Ages brown plant inks were usually produced from the blackthorn bark and wine. In contrast to these soluble brown inks, one of the oldest black writing materials was produced by mixing soot with gum arabic or animal glue dissolved in a small amount of water. From Pliny’s detailed account of the manufacture of various black carbon inks, we learn that producing pure soot of high quality was not an easy task in Antiquity. Iron gall inks are a borderline case between these two groups. They are produced from four basic ingredients: gallic acid, an iron-containing component, gum arabic as a binding media, and an aqueous medium such as wine, beer, or vinegar. By mixing gallic acid with soluble iron ions, a water-soluble ferrous gallate complex is formed. Exposure to oxygen leads to the formation of insoluble black ferric gallate pigment. 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 inks. The Bundesanstalt für Materialforschung und -prüfung (BAM) together with the Centre for the Study of Manuscript Cultures in Hamburg (CSMC) has developed a protocol for ink analysis. It consists of a primary screening to determine the type of the ink and a subsequent in-depth analysis using several spectroscopic techniques (X-ray fluorescence analysis and vibrational spectroscopy). This contribution presents a qualitative and quantitative analysis of historical writing inks to characterize distinguishable inks in manuscripts, to determine the origin of manuscripts, and to assign unknown fragments to time and place.

Since consumers may be exposed to these VOCs immediately after e.g. unwrapping of newly purchased products, reliable analytical methods are needed to determine air concentration profiles in the early phase of VOC emissions. Concerning typical sample sizes of consumer products, micro-scale test chambers (μ-chambers) were considered suitable for this purpose. In addition, compared to medium- or large-scale test chambers, μ-chambers require lower initial investment and operational costs, and offer options for emissions screenings where higher sample throughput is essential. For these reasons, a μ-chamber-based method to determine initial concentrations of VOCs emitting within the first hours of simulated product use was developed. The chamber air was frequently sampled on desorption tubes loaded with Tenax® TA, followed by quantification of emitted VOCs via thermal desorption gas chromatography mass spectrometry (TD-GC-MS). The method was assessed in a round robin test involving eight participating laboratories from 2 countries. Pieces of a rain poncho (sample area A: 2.01·10-4 m2) emitting cyclohexanone, phenol, 2-ethylhexanol, naphthalene and isophorone in significant concentrations were distributed as sample material. Each laboratory conducted triplicate emission tests over a period of 48 h in μ-chambers with volumes of 44 or 114 mL. The loading factors L of 4.57 m2·m-3 (44 mL) or 1.76 m2·m-3 (114 mL) and air flow rates of 24 mL·min-1 resulted in area-specific air flow rates q of 7.17 m3·m-2·h-1 in both chamber types. The temperature was set to 23°C and, if possible, relative humidity was set to approx. 50%. The chamber air was sampled after 0.5, 1, 2, 4, 24 and 48 hours. In addition, to assess the analytical performance, each participating laboratory received two analyte-spiked Tenax® TA-loaded desorption tubes for quality control (QC). Very low relative standard deviations (11–17%) were obtained for the QC test. The results of the emissions tests in the early phase (0.5–4 h) were also adequate, with acceptable z scores (|z|≤2.00) received by six to seven participating laboratories. All eight laboratories obtained acceptable z scores after the longer sampling periods (24 and 48 h). Hence, the inter-laboratory comparability of the results obtained with the developed μ-chamber method was successfully confirmed.

Products, such as building materials and furniture, emit volatile organic compounds (VOCs), which are therefore ubiquitous in indoor air. Different VOC combinations may, under certain environmental and occupational conditions, result in reported sensory irritation and health complaints. A healthy indoor environment can be achieved by controlling the sources and by eliminating or limiting the release of harmful substances into the air. One way is to use materials proven to be low emitting. Meanwhile, a worldwide network of professional commercial and non-commercial laboratories performing emission tests for the evaluation of products for interior use has been established. Therefore, comparability and metrological traceability of test results must be ensured. A laboratory’s proficiency can be proven by internal and external validation measures that both include the application of suitable reference materials. The emission test chamber procedure according to EN 16516 comprises several steps from sample preparation to sampling of test chamber air and chromatographic analysis. Quality assurance and quality control (QA/QC) must therefore be ensured. Currently, there is a lack of suitable reference products containing components relevant for the health-related evaluation of building products. The EU-funded EMPIR project 20NRM04 MetrIAQ (Metrology for the determination of emissions of dangerous substances from building materials into indoor air) aims to develop 1) gaseous primary reference materials (gPRM), which are used for the certification of gaseous (certified) reference materials (gCRM) and 2) emission reference materials (ERM). Most commercial gas standards of indoor-relevant compounds are not certified due to the lack of primary reference materials to which the project aims to contribute. The gPRM under development is a gas-phase standard containing trace levels of VOCs in nitrogen or air from the check standard according to EN 16516 (n-hexane, methyl isobutyl ketone, toluene, butyl acetate, cyclohexanone, o-xylene, phenol, 1,3,5-trimethylbenzene) with a target uncertainty of 5 %. The gPRM can be sampled into sorbent tubes to obtain transfer standards in the form of gCRM. The well characterised ERM represents a sample of a test specimen, e.g. building material, that is loaded into the emission test chamber for a period of several days and is used to evaluate the whole emission test chamber procedure. It shall have a reproducible and temporally constant compound release of less than 10 % variability over 14 days. Different approaches for retarded VOC release, such as the encapsulation of pure compounds and the impregnation of porous materials, are being tested to reach this aim. Furthermore, the design of the ERM is accompanied by the development of a numerical model for the prediction of the emissions for each of the target VOCs. The current progress of the work on both materials will be presented.

Products, such as building materials and furniture, emit volatile organic compounds (VOCs), which are therefore ubiquitous in indoor air. VOC in combination may, under certain environmental and occupational conditions, result in reported sensory irritation and health complaints. Emission concentrations can become further elevated in new or refurbished buildings where the rate of air exchange with fresh ambient air may be limited due to improved energy saving aspects. A healthy indoor environment can be achieved by controlling the sources and by eliminating or limiting the release of harmful substances into the air. One way is to use (building) materials proved to be low emitting. Meanwhile, a worldwide network of professional commercial and non-commercial laboratories performing emission tests for the evaluation of products for interior use has been established. Therefore, comparability of test results must be ensured. A laboratory’s proficiency can be proven by internal and external validation measures that both include the application of suitable emission reference materials (ERM). For the emission test chamber procedure according to EN 16516, no artificial ERM is commercially available. The EU-funded EMPIR project MetrIAQ aims to fill this gap by developing new and improved ERMs. The goal is to obtain a material with a reproducible and temporally constant compound release (less than 10 % variability over 14 days). Two approaches were tested: the impregnation of porous materials with VOC, and the encapsulation of VOC in polymer microcapsules. Impregnation is performed with help of an autoclave and supercritical CO2. The encapsulation is done by interfacial polymerisation on VOC droplets. For both approaches, synthesis and/or material parameters were varied to obtain an optimal ERM. Findings about the optimisation of ERM generation, as well as performance of the best emission reference materials, will be presented.

T1 - Mixed Inks in Two Coptic Documents from the Hermopolite Region Relating to Lease Business N2 - In this article, we present two Coptic papyri, P 11934 and P 11935 from the Berlin collection excavated in Ashmunein (ancient Hermopolis) by Otto Rubensohn in 1906. We employ a multi-disciplinary approach that takes into account both their materiality – writing support as well as ink – and their content, as has become ‘best practice’. 1 Material aspects of written documents have traditionally been the purview of papyrologists. Recently developed methods of scientific analysis generate sets of archaeometric data with the potential to improve understanding of the materiality of ancient document production, as well as to yield new evidence for genuine papyrological research questions. To achieve this, a large corpus of comparative data needs to be built. Our contribution offers a first step in this direction. We aim at presenting the papyri, which were selected because of the ink corrosion during conservation work at the Berlin collection, in a format that is exhaustive both for material and textual aspects. The inks from both papyri were analysed using a combination of techniques, contributing to our better understanding of the development of ink technology in Late Antiquity.

Over the last decade, the popularity of material studies of manuscripts using non-destructive testing (NDT) has increased enormously. These studies are held in especially high esteem in the case of suspicious writings due to the methodological rigour they are reputed to contribute to debate. We would like to stress that materials analysis alone cannot prove that an object is genuine. Unfortunately, audiences with a humanities background often tend to disregard the technical details and treat any published interpretation of instrumental analysis as an objective finding. Four examples are outlined here to illustrate what questionable contributions the natural sciences can make in describing manuscripts that have actually been forged.

Within the following 10 years, clandestine and legal excavations revealed some 900 highly fragmented manuscripts from the late Second Temple period. This collection is generally known as Scrolls of the Judea Desert or Dead Sea Scrolls (DSS). For many years after their discovery, text analysis and fragmeents attribution were the main concern of the scholars dealing with the scrolls. The uncertain archaeological provenance of the larger part of the collection added an additional difficulty to the formidable task of sorting some 19000 fragments. After 60 years of scholar research the question of origin, archaeological provenance and correct attribution of the fragmenst are still hotly debated. To dtermine a possible contribution to the debate from the point of view of writing materials, we used otpical and electron microscopy, various X-ray based techniques as well as vibratiional sprectroscopy. We validated our approach with SY - based studies using the advantages of the synchroton radiation source with respect to the benchtop devices. Our laboratory studies showed that often production and storage locality could be distinguished thenks to the specific residues ("fingerprint") they left on the material. Moreover, we have diescovered that diferrent parchment production processses coexisted in the antiquity, and the resulting writing materials can readily be distinguished.

Coloured ruling with plummet or ink would make a Torah scroll invalid for liturgical use. Ruling lines on some leather fragments of early Oriental Torah scrolls give the impression of being produced with plummet or ink but may be the result of dust in the furrows of relief ruling. Erfurt 9, a fourteenth-century Ashkenazi Torah scroll, has coloured ruling, which is partial secondary re-ruling, on 13 of the 34 surviving sheets, perhaps added when the original relief ruling was difficult to see. The coloured ruling in Erfurt 9 is brown, giving it the visual appearance of iron-gall ink. However, XRF tests showed that the only meaningful metallic component in the coloured ruling was lead (Pb). Lead plummet ruling tends to have a greyish appearance. Black specks under near infrared light are consistent with minium, a lead-based red ink that can turn brown when it degrades. Partial secondary re-ruling added with minium to the original relief ruling comes as a surprise as it would have rendered Erfurt 9 unfit for liturgical use.

During the last years a lot was done to improve the mere technical side of the techniques. Especially in the case of XRF mapping experiments the acquisition speed needed to be increased to allow mapping in the high resolution demanded by the challenges at hand. High resolution in moderate times can now be achieved, but with the price of proportionally increased amount of data that needs to be processed ideally in parallel to the measurement. The classical approach in XRF spectroscopy of elemental fitting of the spectral data does not even come close to fulfill any on the fly processing time constraints and will consume too much processing time in the foreseeable future. In this paper we will discuss the applicability of modern statistical data processing methods to XRF mapping of iron gall ink palimpsests. We will present a comparison of a new approach based on principle and independent component analysis (PCA and ICA) and the standard element mapping method. We will show that a reduction in processing time of almost two orders of magnitude can easily be achieved.

N2 - While studying the socio-geographic history of inks, division 4.5 (Analysis of cultural artefacts and assets) of the BAM (Bundesanstalt für Materialforschung und -prüfung) in Berlin together with the Centre for the Study of Manuscript Cultures in Hamburg has developed a protocol for ink analysis. It consists of a primary screening to determine the type of the ink, and a subsequent in-depth analysis using several spectroscopic techniques. Using this protocol, scientists can assist scholars in addressing a rather broad range of historical questions that cannot be answered unequivocally through scholarly research alone. Among these are investigations on collaboration between scribes and scriptoria, on the usage and annotation of manuscripts and on their path through time and space in general. This research can thus help to reconstruct the circumstances of the production of written heritage as well as their history and transmission. To facilitate the dialogue between the scholars and the scientists a simple optical tool was developed to allow the scholars to perform preliminary ink analysis required for formulation of the question that in turn can be answered by scientific in-depth investigations. In this paper, ink types and their identification method is accompanied by examples of the recent work conducted on parchment manuscripts in the Austrian National Library.

For this purpose, mobile and miniaturized devices were used to measure the paintings in situ. The methodology includes X-ray fluorescence (XRF), VIS spectroscopy (VIS), Raman spectroscopy and diffuse reflectance infrared Fourier transform spectroscopy (DRIFTS). In a first step the capabilities of DRIFTS for binding media classification and pigment identification were tested. DRIFTS enables, besides Raman spectroscopy, the collection of molecular information of a substance that can be used as characteristic fingerprint spectrum. However, the simultaneous collection of both specular (surface) and diffuse (volume) reflection leads to complicated mixed DRIFT spectra, that can vary strongly for one substance depending on the dominant fraction of reflected light. Specular reflection causes several spectral distortions like inverted bands, band shifts and derivative-like features whereas pure diffuse reflections leads to an intensity enhancement of combination bands and overtones. Both specular and diffuse reflection cannot be optically separated, and their proportion depends on material properties like the absorption coefficient and the refractive index as well as on Parameters like surface roughness, porosity, grain size and angle of incidence and detection. A direct comparison of DRIFT spectra with IR spectra of other methods (e.g. transmission, ATR) is not possible, hence the creation of DRIFTS databases was needed. The next step was the complimentary utilization of Raman spectroscopy and DRIFTS for the dentification of synthetic organic colourants. Such colourants are in the further chapters called synthetic organic pigments (SOP) even when it’s not always entirely clear if they are soluble dyes or pigments that are practically insoluble in the medium in which they are incorporated. Raman spectroscopy is generally the method of choice when dealing with SOP, but fluorescence can hamper the Raman spectrum severely, inhibiting the proper identification of the pigment. DRIFTS was successfully applied and several SOP like synthetic alizarin (PR83), the yellow azo pigments (e.g. PY1) or the red and orange β-naphthol pigments (e.g. PR3) could be identified in the paintings solely by means of DRIFTS. The holistic methodological sequence was defined after the successful establishment of DRIFTS as serious analytical alternative. As the time is always the most limiting factor for in situ measurement campaigns in museums, the 9 sequence needs to be time saving but also efficient. The methodology starts with quick measurements by XRF and VIS to get a first idea of the pigment composition, followed by the validation of the results with the vibrational spectroscopies for selected points. Measurements of reverse glass paintings by Carlo Mense and Wassily Kandinsky were conducted to test the entire procedure. A high number of pigments could be identified, including several rare ones like strontium white (SrSO4), PR60 and PB52. The binding media were classified using the previously recorded references. The results were set in the art historian context and were discussed in a multidisciplinary way. The influence of Asian art, especially of Chinese reverse glass paintings as source of inspiration for artists of the “Blauer Reiter” collective (e.g. Wassily Kandinsky, Gabriele Münter, Franz Marc und Heinrich Campendonk) is shown. Non-invasive measurements of two Chinese reverse glass paintings from the late 19th and early 20th century were conducted, enabling a comparison of the palettes of Chinese and European painters. The Chinese palette includes heavy use of red lead and orpiment, pigments that were hardly sed in Europe anymore. More modern pigments like zinc white, cadmium yellow, viridian, chromates, cobalt blues or SOP were not found at all in the Chinese paintings.

In the framework of the ‘PAThs’ project, archaeometric analyses complement the information pieced together by a range of disciplines in the field of humanities. The use of different complementary analytical techniques provides information on the type of ink used and its elemental composition, unveiling interesting details regarding the materials and methodology of manufacturing of writing media. Moreover, this contribution takes a step forward and discusses the possible existence of a regional arrangement in the elemental composition revealed in the inks studied.

Starting from this finding, in June 2018 a preliminary campaign of analysis by means of X-Ray fluorescence (XRF) of external portions removed mechanically from their original rolls in the eighteenth century (the so-called scorze) took place at the Biblioteca Nazionale at Naples. Also in this case, the aim of the survey was to investigate the ink composition in order to detect possible traces of metal. This article sums up the results of this survey.

N2 - In the last decade, applications of X-rays to the study of manuscripts significantly spread in both diversity and extent. They range from writing material analysis, mostly with X-ray fluorescence (XRF), permitting non-invasive characterization of inks and pigments used, to the investigation of the origin of writing supports. In addition, XRF mapping has proved to be an invaluable tool for recovering erased text. Finally, computed-tomography (CT) has shown potential in virtually unrolling rolls, making text readable without using-damaging mechanical methods. Despite their growing use, little attention has been paid to the side effects of such analytical tools. We observed irreversible parchment colour changes during some experiments on dead-sea scrolls with synchrotron radiation sources. Furthermore, partial photo-reduction of iron under high intensity beam during X-ray absorption near edge structure spectroscopy (XANES) measurements of iron-gall ink on paper has been reported several times [5,6]. Such phenomena have mostly been overlooked so far, although there is an increasing awareness of the necessity to study them. We conducted experiments at the Deutsches Elektronen-Synchrotron (DESY) facilities to investigate X-ray induced structural alteration of paper and parchment to see whether the presence of absorption centres (ink and pigments) has an impact. In addition to better understanding degradation processes, we are aiming to define an appropriate methodology of analysis of manuscripts with a tolerable risk of damage. The first results concerning X-ray induced damage of cellulose materials have already been presented at the Synchrotron Radiation and Neutrons in Art and Archaeology (SR2A). We are focusing here on the results on parchment materials.

A1 - Hahn, Oliver A1 - Golle, U. T1 - Blindness and Insight. The Rhetoric of Connoisseurship and the Investigation of Materiality. N2 - The aim of the lecture is to present the productive interplay of connoisseurs and material analysis using the example of selected drawings from the Rembrandt collection of the Klassik Stiftung Weimar. We try to determine the point at which the question of the materiality of the drawings makes sense in the traditional discourse of connoisseurship. On the one hand, this involves the question of authorship – Rembrandt – or not? – and the locating of attributed drawings in the context of the work. On the other hand, it is about making drawing processes visible, characterizing ways of drawing and workshop practices as well as distinguishing different forms of reworking and copying within the Rembrandt workshop. The material analyses culminate in the question of whether Rembrandt’s inks can be distinguished at all. It becomes apparent that the newly gained knowledge about the materiality of the drawing no longer reveals itself to the “mere” view of the connoisseur. Rather, it is only generated by the digital image. The rhetoric of connoisseurs must therefore be contrasted with the necessity of a hermeneutics of the digital image. The envisaged “material turn” of drawing science is thus simultaneously able to take up the critique of the question of authorship, which has been growing ever more recently, and to transfer it to a more comprehensive perspective of aesthetics of production.

Möglichkeiten und Grenzen N2 - Eine neue Panik macht sich in Deutschland breit: sind alle Bücher, die einen grünen Farbschnitt oder Umschlag haben und damit giftiges Arsen enthalten, eine Gefahr für Mensch und Umwelt? Der Vortrag blickt aus archäometrischer Perspektive auf das Phänomen und stellt klar, dass seit der Antike gesundheitsschädliche Pigmente Verwendung fanden und dass seit dem späten Mittelalter schriftliche Belege für den sorgfältigen Umgang mit solchen Gefahrstoffen existieren. Die Farbe "grün" ist keineswegs die einzige Farbe, die "Gifte" enthalten kann. Zudem lässt sich die Palette der "gefährlichen" Elemente mit Blei, Quecksilber, Cadmium oder Chrom deutlich erweitern.

In the past, scholars have speculated about the relationship between the inks using highly subjective observations. For example, The scholars spoke about “apricot” and “chocolate” distigmai, arguing for their respective origins based on their visual similarity to the original ink and that of the medieval reinker, respectively. In recent decades, micro X-ray fluorescence (µXRF) has revolutionized the study of ancient and medieval cultural artifacts, making it possible to examine them using objective criteria. The application of such objective scientific measurements to ancient and medieval manuscripts will be explained with examples of how color, hue, and appearance of ink can be highly misleading.

Auch wenn in beiden Fällen Glas das Trägermaterial ist, bezeichnet Hinterglasmalerei jedoch eine völlig andere Technik. Während bei der Glasmalerei die Farben auf den Bildträger eingebrannt werden, handelt es sich bei der Hinterglasmalerei um eine Kaltmalerei. Selbsttrocknende Farben werden auf die Rückseite der Glastafel aufgetragen, zuweilen wird die Malweise durch aufwendige Veredelungstechniken ergänzt. Mehr und mehr rückt diese Technik, die materialtechnologisch zwischen Tafelmalerei und Glasmalerei zu verorten ist, in den Blickwinkel einer interessierten Öffentlichkeit, wie dies eine zunehmende Anzahl verschiedener Ausstellungen zur Hinterglasmalerei belegen.

T1 - Inks Used to Write the Divine Name in a Thirteenth-Century Ashkenazic Torah Scroll: Erfurt 7 (Staatsbibliothek zu Berlin, Ms. or. fol. 1216) N2 - The scribe of ‘Erfurt 7’, a thirteenth-century Torah scroll now kept in Berlin, initially left blank spaces for the divine appellations Elohim ( אלהים ) and YHWH Elohim ( ,(יהוה אלהים which were filled in during a second stage of writing. The appearance of the ink employed to write the appellations was significantly darker than that of the surrounding ink. X-ray fluorescence analysis (XRF) has shown that the light and dark brown inks had similar elemental compositions, but contained different ratios of iron to potassium, which could be explained by the use of different batches of ink. According to some medieval sources, the divine appellations were sometimes filled in during a second stage of writing in the presence of ten men from the Jewish community. In Erfurt 7, the two-stage procedure was only performed in the first 1.5 columns of the original sheets, suggesting it may have been part of a public ceremony inaugurating the writing of the divine names in the scroll. Erfurt 7 emerges from this study not only as a ritual object used for liturgy, but as a rallying point for the Jews of Erfurt to come together as a community to express their reverence for the written form of God’s name. The divine name YHWH ( יהוה ) was written in a smaller script than the surrounding text on three replacement sheets using the same two-stage procedure. The ink used on the replacement sheets contained zinc, which is characteristic of other Erfurt manuscripts as well. This suggests that Erfurt was the place where the scroll was used, cherished and eventually repaired.

Possible application of a non-destructive analytical method N2 - VIS-spectrometry is a rapid, non- invasive, mobile method that offers a first overview of possible colorants used for painting. This is worked out in detail for European paintings and applied for artefacts and illuminated manuscripts. Manuscripts from Asia for example show colorful decoration identified to be mostly prepared with mineral pigments such as cinnabar, azurite, malachite or orpiment, which can be well confirmed by elemental analyses due to their color-giving metal ions. This is not the case for the colorants used in pictorial manuscripts from pre-Hispanic America, painted mainly with organic dyes from plants. The palette of colors used by the Aztecs is very rich due to their extensive empire and long- distance communication with vassal states liable to tributes including dyes of high quality. These include for example red cochineal, yellow zacatlaxcalli, tagetes, safflower, and achiotl, as well as blue indigo, or matlalli.

Einige Pigmente und Farbstoffe, d.h. Tinten, Stifte oder Kreiden, waren nur für den Gebrauch als Zeichenmittel vorgesehen – andere wiederum finden sich auch in der Tafel- oder Fassmalerei. Ausgehend von schwarzen Zeichenmaterialien soll zunächst eine allgemeine Typologie der Farbmittel entwickelt werden, um den Kosmos dieser Vielfältigkeit zu illustrieren. In einem zweiten Teil werden farbige Elemente am Beispiel von Rötel in Zeichnungen hinterfragt, deren Funktion und Bedeutung sich aus der Betrachtung heraus nicht unbedingt sofort erschließt. So diente die Farbe hier weder der naturgetreuen Nachahmung, noch wurde sie für eine nachträgliche Wertsteigerung eingesetzt. Der dritte Teil dieses Exkurses widmet sich schließlich solchen „farbigen“ Elementen, deren Konnotationen sich aus den Zeichnungen nicht ermitteln lassen und die daher zunächst irritieren. Diese vermeintliche Farbigkeit war aber ursprünglich vielleicht gar nicht intendiert, sondern ist vielmehr auf Alterungs- und Korrosionsprozesse zurückzuführen.

They uniquely reflect the relationships between indigenous culture and Spanish colonial masters. This study focusses on the scientific investigation of three manuscripts (Manuscripta Americana 3, 8, and 10) that are kept today in Krakow. It is assumed that these three parts belong together in a certain way, so various material analyses were carried out to prove this assumption. The scientific investigation focusses on the different black and brown writing inks.
