Ink analysis was performed in November 2018 on Cod. Pal. germ. 330 and Cod. Pal. germ. 389 at Universitätsbibliothek Heidelberg and on Cod.poet.et.phil.fol.1 at Württembergische Landesbibliothek Stuttgart.
The results are published in:
Bosch, Sebastian. (2022). The inks of "Der Welsche Gast": non-invasive analysis by XRF spectroscopy and nIR microscopy.
All data uploaded here was recorded with the following instruments:
DINO:
micrographs (bmp files) were recorded under visible (VIS), ultraviolet (UV) and near infrared (NIR) light with the three-colour imaging USB microscope (Dino-lite AD413T-I2V, Metav, Germany);
images were not taken from manuscript Cod.poet.et.phil.fol.1, since this manuscript was imaged with a Multispectral Imaging (MSI) camera (dataset will be published soon).
ARTAX:
XRF raw spectra (linescans) were recorded with the portable XRF spectrometer ARTAX (Bruker Nano GmbH, Germany);
the raw spectra were saved in subfolders 01_rtx (rtx files);
with ARTAX software SPECTRA 7.2.5.0 (Bruker Nano GmbH, Germany) micrographs of the measuring spots were exported in subfolders 02_bmp;
accumulated spectra were generated and exported in subfolders 03_txt (txt files) and 04_spx (spx files);
evaluated net intensity values of assigned elements were exported in subfolders 05_csv (csv files);
evaluated rtx files were saved in subfolders 06_ev_rtx (rtx files);
new project files (rtx files) were generated for inks and red inks using the corresponding spx files;
evaluated net intensity values were exported in subfolders 07_ev_xls (xls files);
evaluated rtx files were again saved in subfolders 06_ev_rtx (rtx files);
processed data was further plotted and evaluated with the software OriginPro 2018G and saved in subfolders 08_opju (opju files);
documentation of measurement spots (pdf files).
This research was funded by the German Research Foundation (Deutsche Forschungsgemeinschaft, DFG), first as part of Sonderforschungsbereich 950 (SFB 950) and then under Germany's Excellence Strategy programme (EXC 2176 "Understanding Written Artefacts: Material, Interaction and Transmission in Manuscript Cultures", project no. 390893796). The research was conducted within the scope of the work conducted at the Centre for the Study of Manuscript Cultures (CSMC) at Hamburg University .
