T1 - Rötel und Eisengallustinte als Farbeffekte in der Zeichnung N2 - Eine Vielzahl unterschiedlicher Materialien findet für die farbliche Gestaltung von Zeichnungen Verwendung. 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.

T1 - Schwarz auf Weiß N2 - In der Sammlung des Naturwissenschaftlichen Kabinetts Johann Wolfgang von Goethes wird ein eher unscheinbares Stück Papier aufbewahrt, welches einen grauschwarzen Aufstrich aufweist. Bei genauerer Betrachtung glaubt man, drei Querstreifen mit rötlicher, weißlicher und bläulicher Farbe innerhalb des grauschwarzen Aufstrichs zu erkennen. Das Papier weist oben die Skizze eines Prismas, im mittleren Bereich am rechten Rand die Beschriftungen „violett/blau“, „weiß“ sowie „gelb/roth“ auf. Interessanterweise ist die Aufschrift „violett/blau“ dem eher rötlichen, die Aufschrift „gelb/roth“ dem eher bläulichen Querstreifen zugeordnet. Die rechte untere Ecke ist mit „Sk“ (Seebeck?) gekennzeichnet. Sowohl die Beschriftungen als auch die Skizze wurden mit einem Graphitstift ausgeführt. Das Papier ist auf eine Pappe mit Papprahmen geklebt und mit schwarzem Papier umwickelt. Es ist unumstritten, dass es sich bei diesem Objekt um das Ergebnis eines naturwissenschaftlichen Experiments handelt, doch was stellt es dar und lässt sich die ursprüngliche Versuchsanordnung aus dem vorliegenden Befund und weiterer, heute zugänglicher naturwissenschaftlichen Untersuchungen rekonstruieren?

T1 - Scientific Analysis of Leonardo’s Manuscript with Anatomic Drawings and Notes N2 - In this paper, we discuss the importance of scientifically investigating cultural artefacts in a non-invasive way. Taking as test case Leonardo da Vinci’s Manuscript with anatomic drawings and notes, which is stored in Weimar, we clarify fundamental steps in the chronology of this folio. By means of microscopy, infrared reflectography, UV photography, and X-ray fluorescence analysis, we were able to identify various types of sketching material and several varieties of iron gall ink. For his sketches, Leonardo used two different sketching tools, a lead pencil and a graphite pencil, as well as several types of ink for developing these sketches into drawings. With regard to ink, it is important to observe that there is no difference between the ink Leonardo used for drawing and the ink he used for writing text. Based on the materials analysed, we suggest a chronology for the creation of this unique folio.

Due to technological developments, technical diagnostics in art and culture are in ever-greater demand in such fields of transdisciplinary research. Natural sciences play auxiliary role in the studies of manuscripts. The success of their contribution depends strongly on the formulation of the question, the choice of the methods to obtain the requested answer, and appropriate reference databases. First, report was given on the measurements performed on local raw materials, such as, plants, minerals and animals, which constitute the reference session. Then, the first results of the scientific analysis of several fragments from the Malian manuscript collections were present.

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.

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.

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.

Insights into the painting technique along with art historical comparisons provided the opportunity for a better understanding of the painting’s genesis, in particular concerning an early reworking of the background by the artist. A recovery and reconstruction of the earlier version of the background is now possible. The discovery of zinc in distinct passages of the painting, as well as the grey-black pigment stibnite and glass particles used as a supplement in paint layers are of special interest.

Aside from Zerdoun’s mention in her outstanding review of written sources, “Les encres noires au Moyen-Âge”, this ink category has received little if any attention from scholars and scientists. And yet, if analytically attested, the use of such inks could serve as an additional category to classify and distinguish the writing inks on the historical socio-geographic map of the writing inks we are trying to build.

In rare cases, inks typology has been determined by means of microscopy and reflectography, i.e. using their physical and optical properties, respectively. Since carbon, plant and iron gall inks belong to different classes of compounds they could be easily distinguished had only pure inks been used. Even these crude observations suggest that the inks used differed greatly in their composition. Reconstruction of the ink recipes with the help of advanced non-destructive analytical techniques could serve as a powerful accessory for in the studies of ancient papyri. The proposed paper will present a short survey of the methods of material analysis and the challenges offered by ancient inks. The examples of the ink studies from the collections of the Israel Museum in Jerusalem and Egyptian Museum in Berlin will conclude the paper.

Scientific systematic study of inks from Coptic manuscripts N2 - While studying the socio-geographic history of inks, division 4.5 of the BAM (Bundesanstalt für Materialforschung und Prüfung) 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: XRF, FTIR, and Raman. In most cases, we can obtain satisfactory results using a non-invasive protocol. However, mixed inks that contain no metals evade such a protocol. These inks constitute a heterogeneous group of media used especially in the Middle East and the Islamicate world since at least the 10th century; they are characterized by blending carbon ink and tannins, with or without the addition of vitriol. Our own research aims primarily at recreating a socio-geographic history of inks, parchment, and papyrus and includes the comparative analysis of the writing materials of the Dead Sea Scrolls, ink and papyrus in Ancient and Hellenistic Egypt, and inks in documents from various contemporary medieval communities in Fustat (first nucleus of Cairo). During many years of study, we concluded that the continuous production of Coptic manuscripts from late Antiquity to the Middle Ages offers a unique opportunity for historical study of the ink in a large geographic area. Thanks to the collaboration with the ERC project “PAThs” (www.paths.uniroma1.it), based at the University of Rome La Sapienza, and within the activities of a PhD research dedicated to this topic, we therefore created a new branch of our project focused entirely on the analysis of Coptic inks, pigments, and dyes. This pioneering systematic study of writing materials coming from a specific area and time frame (5th-10th century) aims not only at a better understanding of the complex Coptic multicultural and plurilingual society, but also and mainly at clarifying the links among the Coptic and other societies between the ancient and medieval eras. Finally, it will cast light on the history of the technological development of inks in the eastern world, from Antiquity to the middle ages.

Die in der frühen Kolonialzeit hergestellten verschiedenartigen Codices waren damals schon nicht mehr an den Orten ihrer ursprünglichen Verwendung. Entsprechend ihres Seltenheitswertes gelangten einzelne Schriftstücke seit der Conquista in die Bestände bedeutender Persönlichkeiten. Hierzu fertigte man auch Abschriften oder Kopien an, oder zerstückelte sogar einzelne Blätter, so dass die Darstellungen auf den abgetrennten Fragmenten oft nur zum Teil abgebildet vorliegen. Um herauszufinden, ob einige Schriftstücke der "Humboldt Codices" in Bezug zu einander stehen, werden die Dokumente, ihre Symbole und Schriftzeichen und das zur Herstellung verwendete Material miteinander verglichen. Mit den für die Analyse von Manuskripten bewährten Untersuchungsmethoden werden Papier und Farbmittel identifiziert. Hierzu zählen Raman-, FTIR-, Röntgenfluoreszenz- und VIS- Spektroskopie. Charakteristisch für die Herstellung von schriftlichen Dokumenten in der Kolonialzeit von Amerika ist die Verwendung von indigenem Material wie Papier aus Baumrinde und Pflanzenfarben zusammen mit den aus Europa bekannten Materialien. Geklärt wird, inwieweit neben den bekanntesten Farbstoffen wie Cochenille, Mayablau oder Mischungen mit Tonmineralen auch mineralische Pigmente zum Einsatz kamen. Vorgestellt werden die auf Tafel 36 in den "Vues des Cordillères et Monuments des Peuples Indigènes de l`Amerique, Voyage de Humboldt et Bonpland" abgebildeten Fragmente. Die hier von Humboldt vorgenommene Zusammenstellung wird mit der Farbpalette der in Berlin archivierten originalen Schriftstücke verglichen. Die Interpretation der Ergebnisse gibt einen Hinweis auf die Zuordnung oder auch Zusammengehörigkeit dieser einzigartigen Dokumente amerikanischer Geschichte. Hierbei wird die Frage aufgeworfen, inwiefern davon auszugehen ist, dass diese mit weiteren Fragmenten in Verbindung gebracht werden können, was für die Beleuchtung der kulturhistorischen Zusammenhänge von großer Bedeutung ist.

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.

To ensure the comparability of results from different testing laboratories their measurement performance must be verified. For this purpose, Bundesanstalt für Materialforschung und -prüfung (BAM) organizes an international proficiency test every two years using well-characterised test materials (one sealant, one furniture board and four times a lacquer) with defined VOC emissions. The materials fulfilled the requirements of homogeneity, reproducibility, and stability. Altogether, 41 VOCs were included of which 37 gave test chamber air concentrations between 10 and 98 µg/m³. This is the typical concentration range to be expected and to be quantified when performing chamber tests. Four compounds had higher concentrations between 250 and 1105 µg/m³. The relative standard deviations (RSD) of BAM proficiency tests since 2008 are compared and the improvement of the comparability of the emission chamber testing is shown by the decrease of the mean RSD down to 23% in 2021. In contrast, the first large European interlaboratory comparison in 1999 showed a mean RSD of 51%.

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.

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.

Schriftenreihe des Netzwerks zur interdisziplinären Kulturerhaltung hatte ich angeführt, dass bei der Untersuchung von kulturellen Artefakten naturwissenschaftliche Untersuchungsmethoden zunehmend an Bedeutung gewinnen, sie eigentlich unverzichtbar geworden sind. Ein besonders einprägsames Beispiel dieser fächerübergreifenden Zusammenarbeit zwischen Geisteswissenschaften, Naturwissenschaften und Restaurierungswissenschaften war die Ausstellung Johannes Vermeer. Vom Innehalten, die in diesem Jahr in der Gemäldegalerie Alter Meister in den staatlichen Kunstsammlungen Dresden gezeigt wurde. Eigens für diese Ausstellung wurde das Gemälde Brieflesendes Mädchen am offenen Fenster einer grundlegenden Restaurierung unterzogen. Diese Restaurierung diente jedoch nicht nur der Reparatur des Bildes. Um sich dem ursprünglichen Zustand des Gemäldes zwischen 1657 und 1659 anzunähern, wurden später hinzugefügte Malschichten großflächig abgenommen. Möglich wurde dies durch unterschiedliche, bildgebende materialwissenschaftliche Untersuchungen im Vorfeld, welche die wissenschaftlichen Grundlagen für die Diskussion über den weiteren Umgang mit der Lesenden schufen. Materialanalytische Verfahren wurden und werden ständig weiterentwickelt und optimiert. Sei es, um aus einer Vielzahl von Einzelmessungen ein Gesamtbild zu erstellen, oder die Größe einer Probenentnahme so zu reduzieren, dass von einer „minimal-invasiven“ oder „quasi nicht-invasiven“ Untersuchung ausgegangen werden kann. Nun feiert die Bundesanstalt für Materialforschung und -prüfung, zusammen mit ihren Vorgängerinstitutionen, den königlichen Versuchsanstalten, in diesem Jahr ihren einhundertfünfzigsten Geburtstag. Sie blickt damit auf eine lange Tradition materialwissenschaftlicher Analysen zurück, an deren Beginn beispielsweise die metallographischen Untersuchungen von Adolf Martens stehen. Derartige Untersuchungen bilden auch heute noch einen wesentlichen Bestandteil archäometallurgischer Forschung. Die Historie bzw. die Weiterentwicklung der Methodik lässt sich hier besonders gut nachzeichnen. Jedoch blicken auch Verfahren zur Charakterisierung weiterer Werkstoffe, wie Glas, Keramik, oder organischer Materialien auf eine lange Geschichte zurück. Die in diesem Band der N.i.Ke.-Schriftenreihe präsentierten Beiträge dokumentieren einerseits aktuelle Forschungsarbeiten, die erst in diesem Jahr in entsprechenden Fachjournalen publiziert wurden, andererseits liegen einige der Arbeiten bereits 50 Jahre zurück. Sie bekunden damit nicht nur die materialtechnologische und historische Bandbreite der Projekte, sondern offenbaren die Vielfältigkeit kulturhistorischer oder restauratorischer Fragestellungen, zu deren Beantwortung natur- und materialwissenschaftliche Forschung wesentliche Beiträge liefern können. Ich bedanke mich bei allen Kolleginnen und Kollegen, die zur Erstellung dieser dritten Ausgabe der N.i.Ke. Schriftenreihe des Netzwerks zur interdisziplinären Kulturerhaltung beigetragen haben. Ihre Aufsätze ermöglichen den Blick in die Vielfältigkeit materialwissenschaftlicher Untersuchungen im Bereich Kunst- und Kulturgut. Ich wünsche Ihnen viel Spaß auf dieser kleinen Zeitreise.

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.

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.

Thus, a good indoor air quality is important. Emissions of volatile organic compounds (VOCs) from furniture and building materials can cause health complaints1. Quantitative VOC-emission testing is carried out under standardized conditions in emission test chambers. In the presented project an emission reference material (ERM) is developed that emits a defined mixture of VOCs which is required for quality assurance and -control (QA/QC) measures. Porous materials (e.g zeolites, activated carbons, MOFs or aerogels) are used as reservoir materials and impregnated with VOC. The porous materials are selected, among others, by their pore size, pore size distribution, polarity and availability. Due to their regular pore structure zeolites are tested at first. For a prediction of the emission profile, the ERM is supposed to exhibit a constant emission rate over time. The aim is a stability of ≤ 10 % change in the emission rate over a minimum of 14 days. Method For impregnation, the material is placed into an autoclave inside a rotatable basket. The VOC is added and the autoclave is closed. Afterwards, CO2 is inserted. The closed system is then heated to the supercritical point of CO2 (31 °C, 73.75 bar). In this state, the CO2 acts as solvent for the VOC. By rotating the basket, the distribution of the VOC is ensured. After a few minutes, the pressure is decreased slowly and the CO2 is released. For the determination of the emission profile, the impregnated sample is placed into an emission test chamber. These chambers can be operated either with dry or humid air (50 ± 5 % rel. humidity). Every second to third day, air samples are taken and analyzed by gas chromatography. For an ideal impregnation, several different pressures and temperatures as well as impregnation times are tested. Results Two zeolite materials tested in dry air conditions reach emission profiles with a decrease of less than 10 % over 14 days (heptane and toluene, respectively). Further it was discovered that smaller pellets of the same zeolite show better results than bigger particles. When the pore size of a zeolite is too small, e.g. 0.3 nm, the VOC cannot be absorbed sufficiently. The main disadvantage of zeolites is their hygroscopicity because it has a large impact on the release of VOC when they are used in emission test chambers under standardized test conditions (23 °C, 50 % rel. humidity). Activated carbons have emission profiles with a larger change over 14 days. However, the high hydrophobicity allows measurements in humid air conditions which was not possible with the before mentioned hygroscopic zeolites. It is possible to impregnate powdered materials as well, and thus powdered non-hygroscopic (n.h.) zeolites were impregnated. Their emission profiles are comparable to those of the activated carbons. The use of methylated hygroscopic zeolites with a decrease in hygroscopicity did not yield successful emission measurements. The change over 14 days is calculated only for the stable phase (~250–300 h). The desired stability of ≤ 10 % change of the emission rate over 14 days could already be reached under dry testing conditions. Further investigations under humid conditions show that zeolites with high Si/Al-ratios are non-hygroscopic and comparable to activated carbons (20–30 % change). The next step is to reduce the change in the emission rate of these materials to the aimed ≤ 10 % over 14 days.

Fast alle stammen sie aus der ehemaligen Sammlung des Italieners Lorenzo Boturini, deren Reste heute über mehrere Länder verstreut sind. Der hohe Fragmentierungsgrad sowie ungeklärte Fragen zur Provenienz und Genese der Bruchstücke machen es schwierig, sie zu rekontextualisieren. Um dies dennoch zu erreichen, kommen einander ergänzende moderne natur- und kulturwissenschaftliche Methoden zum Einsatz. Als Beispiel einer Neuzuordnung werden die Humboldt-Fragmente IX-XII vorgestellt. Dass die vier Bruchstücke verwandt sind, wurde schon lange vermutet, nicht jedoch, dass sie zusammen mit einem nicht mehr vorhandenen Mittelteil ein einziges Dokument gebildet haben. Die Gründe für eine derartige Rekonstruktion werden als Ergebnis der Forschungsarbeiten diskutiert.

Die nicht-invasiven Analysen ermöglichen Informationen zur Herkunft, zum Herstellungsprozess und möglicherweise zum Alter (direkte Dating nicht möglich, Ausnahme: Papierstruktur, Wasserzeichen). Die zerstörungsfreien Analysen können Rückschlüsse auf mögliche Fälschungen geben, sind neben den offensichtlichen Vorteilen jedoch auch mit einzelnen Limitierungen behaftet. Der Vortrag soll anhand einiger Fallbeispiele die Möglichkeiten aber auch Grenzen bei der zerstörungsfreien (mobilen) Auffindung von Fälschungen aufzeigen.

Les résultats réunis dans cette étude semble indiquer que les scribes achètent leur propre encre. L’analyse des encres peut nous aider à retracer une chronologie de l’écriture et signature de certains documents juridiques. Élargissement du corpus: - Comparaison avec des documents écrits par la cour du Qadi - Documents d’autres collections - Avec d’autres documents contemporains (Génizah Afghane) N2 - Conclusion and track: It seems that there is no correlation between the type of ink used and other criteria sought apart from a mark of personal preference, except with regard to religious documents, in which case a difference is made according to the community. The results gathered in this study seem to indicate that scribes purchased their own ink. Ink analysis can help us trace a chronology of the writing and signing of certain legal documents.
