There are three typologically different classes of black writing inks: soot inks consist of carbon particles.

Their inks appear brownish, although they date back to the fourth and third century BCE, when carbon inks are believed to have been commonly if not exclusively used. Using imaging micro-X-ray fluorescence and infrared reflectography, we discovered that the inks in both documents contain a significant amount of copper in addition to carbon. Comparing the extant recipes for black writing inks and the experimental evidence, we suggest that these inks are a transition between the pure carbon and the iron-gall inks. Such inks may have been quite common before the production of iron-gall ink was clearly understood and established.

Fr. 9084: one or two palettes? N2 - The manuscript of the History of Outremer by William of Tyre stored at the BNF (ms. fr. 9084) is believed to have been illustrated by two different hands. Indeed, the first five miniatures of this manuscript appear to be very different from the last seventeen, which were supposedly painted by an artist known as the "Hospitaller Master". This painter worked on at least two manuscripts in Paris between 1276 and 1280, and eight more in Saint Jean d'Acre before 1291. During his stay in the Latin Kingdom of Jerusalem, his palette changed and reached its most important development in the Manuscript of the History of Outremer, maybe influenced by the colourful crusader style of the first five miniatures. The present work aims at identifying the pigments used on both parts of the manuscripts and see whether they are the same for both artists or not. For that, portable XRF analysis was used directly at the Bibliothèque National de France in Paris, where the manuscript is stored. This allowed a quick, non destructive and non invasive study of the manuscript. Significant differences were observed in the compositions of some pigments indeed, in particular for the red and green, showing the use of different palettes. This could indicate that the Hospitaller Master not only brought his knowledge and style, but also probably part of his palette of pigments with him when moving to Saint Jean d'Acre.

N2 - Two main types of inks coexisted in Early Medieval times: carbon inks and iron-gall inks. Many variations within these types existed, depending on the source of raw materials and their proportion. In addition to these, an intermediate mixed type of ink, with both iron and carbon as colouring agents, was sometimes used, especially in early Arab manuscripts. Two projects are being conducted currently at the Bundesanstalt für Materialforschung und -prüfung (BAM) concerning the analysis of inks with Raman spectroscopy. The first one aims at comparing the spectra of different carbon inks from Antiquity to the Middle Ages with Raman spectroscopy, while the second one focuses on the identification and comparison of mixed inks. For the first project, several carbon inks were made using different sources of carbon (pine soot, olive oil soot, date seeds charcoal etc.) and various binders (fish glue, gum Arabic, proteinic binder etc.), following antique recipes. These inks were then analysed with Raman spectroscopy and fitted with the “two-peaks” and the “three-peaks” models following the procedure described by Goler et al., to help spotting differences between the spectra, depending on the recipe. Some samples were then disposed in an ageing chamber at 80°C and 60% RH and analysed again in order to determine whether changed in the spectra are observable. The procedure proposed by Goler et al. to date inks with Raman spectroscopy was also evaluated during this process. Although several carbon inks could be distinguished from their spectra, no differences were seen between aged and fresh samples. Furthermore, experimental conditions were found to have such a significant influence that reliable dating of inks through Raman spectroscopy seems dubious.

T1 - The quest for the mixed inks N2 - In this article, we would like to share our observations concerning the inks produced by intentionally mixing soot or charcoal with tannin extracts or iron-gall ink. 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.

T1 - An Attempt at a Systematic study of inks from Coptic manuscripts N2 - It is well documented that throughout Antiquity, ancient Egyptians used mostly carbon inks as a writing material. In Late Antiquity, some metals started to be added to carbon based inks. We have records of five manuscripts from the Dead Sea Scrolls collection whose carbon inks were found to contain copper Also, lead was recently found as an additive in carbon inks on a charred fragment from Herculaneum. Furthermore, the earliest evidence of iron-gall ink was found in the Book of Proverbs (Codex Ms. Berol. orient. oct. 987) dating to the third fourth centuries ce. It has been suggested that along with carbon and iron-gall inks, there is no reason to think that purely tannin inks were not also in use in Egypt. However, so far, we just have evidence of a copper-tannin ink identified in a number of documents from Egypt in the first third centuries bce. In an attempt to fill this gap in this extremely fragmented scenario during our studies of the socio-geographic history of inks, we arrived at the conclusion that the continuous production of Coptic manuscripts from Late Antiquity to the Middle Ages offers a unique opportunity for the historical study of inks across a large geographic area.

A1 - Rabin, Ira T1 - XRF ink Analysis of some Herculaneum papyri N2 - Recent research has suggested that some of the inks used in Herculaneum papyri do not consist of pure carbon. 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.
