Scientific analysis of three manuscripts of "Der Welsche Gast", Universitätsbibliothek Heidelberg, Cod. Pal. germ. 330 and Cod. Pal. germ. 389, and Württembergische Landesbibliothek Stuttgart, Cod.poet.et.phil.fol.1

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:<br>
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:

<strong>DINO:</strong><br>
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);<br>
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).

<strong>ARTAX:</strong><br>
XRF raw spectra (linescans) were recorded with the portable XRF spectrometer ARTAX (Bruker Nano GmbH, Germany);<br>
the raw spectra were saved in subfolders <strong>01_rtx</strong> (rtx files);<br>
with ARTAX software <em>SPECTRA 7.2.5.0</em> (Bruker Nano GmbH, Germany) micrographs of the measuring spots were exported in subfolders <strong>02_bmp</strong>;<br>
accumulated spectra were generated and exported in subfolders <strong>03_txt</strong> (txt files) and <strong>04_spx</strong> (spx files);<br>
evaluated net intensity values of assigned elements were exported in subfolders <strong>05_csv</strong> (csv files);<br>
evaluated rtx files were saved in subfolders <strong>06_ev_rtx</strong> (rtx files);<br>
new project files (rtx files) were generated for inks and red inks using the corresponding spx files;<br>
evaluated net intensity values were exported in subfolders <strong>07_ev_xls</strong> (xls files);<br>
evaluated rtx files were again saved in subfolders <strong>06_ev_rtx</strong> (rtx files);<br>
processed data was further plotted and evaluated with the software <em>OriginPro 2018G</em> and saved in subfolders <strong>08_opju</strong> (opju files);<br>
documentation of measurement spots (pdf files).
