A1 - Wolff, Timo T1 - Das Schwarzlot in der Hinterglasmalerei - Zerstörungsfreie Untersuchung von Kunst- und Kulturgut N2 - Die Bedeutung der Zerstörungsfreien Prüfung im Bereich der Kunst- und Kulturanalyse hat in den letzten Jahren deutlich zugenommen. Mobile Untersuchungstechniken erweisen sich als besonders geeignet, da die fragilen und kostbaren Objekte in den Museen verbleiben und somit keine Schädigungen durch Transport oder Klimawechsel erleiden können. Dieser Beitrag möchte am Beis piel der Hinterglasmalerei die Bedeutung der naturwissenschaftlichen Analyse im Bereich der Kunstgeschichte aufzeigen. Der Begriff der Schwarzlotmalerei wird in der Kunstgeschichte allgemein für eine schwarze Konturmalerei verwendet. Während der Begriff in der Glasmalerei eindeutig das Material – ein mit Eisen- und Kupferoxiden schwarz gefärbtes Bleiglas – bezeichnet, steht der Begriff in der Tafelmalerei für tiefschwarze Konturen auf Goldgründen und Lüstern. Diese Modellierung ist jedoch im Vergleich zur Glasmalerei - soweit bekannt - mit organischen Schwarzpigmenten ausgeführt. Auch die Hinterglasmalerei, und hier insbesondere die des späten Mittelalters zeichnet sich durch eine dominierende schwarze Konturmalerei aus. Mittels zerstörungsfreier Röntgenfluoreszenzanalyse konnte in einer Auswahl repräsentativer Objekte Schwarzlot nachgewiesen werden. Bezogen auf die Konturierungen ist hier eindeutig der stilistische, aber auch der maltechnische Einfluss der Glasmalerei auf die Hinterglasmalerei ablesbar. Es ergibt sich aber ein wesentlicher Unterschied – bis auf wenige Ausnahmen wurde hier das Schwarzlot nicht eingebrannt, sondern als Kaltbemalung verwendet.

T1 - Reference-free X-ray fluorescence analysis of an ancient Chinese ceramic N2 - The investigation of an ancient Chinese ceramic served to further develop and validate fundamental parameter-based quantitation procedures in reference-free x-ray fluorescence (XRF) analysis. The XRF measurements of this sample were performed at the four-crystal monochromator beamline of the Physikalisch-Technische Bundesanstalt (PTB) at the BESSY II synchrotron radiation facility employing different excitation energies. The parallel processing of the XRF spectra recorded at different excitation energies provides a means to simultaneously evaluate relevant fundamental parameters and secondary enhancement processes such as those induced by photoelectrons. Employing well-characterized and absolutely calibrated instrumentation, all experimental parameters involved in XRF are known for small relative uncertainties allowing for a completely reference-free quantitation. Apart from traces of rare earth elements, the analytical results of the Chinese ceramic achieved by reference-free XRF are in line with target values given within a proficiency test of the International Atomic Energy Agency (IAEA) involving atomic and nuclear methods.

T1 - A compact 3D micro X-ray fluorescence spectrometer with X-ray tube excitation for archaeometric applications N2 - In this work, the applicability of a new 3D micro X-ray fluorescence (3D Micro-XRF) laboratory spectrometer for the investigation of historical glass objects is demonstrated. The non-destructiveness of the technique and the possibility to measure three-dimensionally resolved fluorescence renders this technique into a suitable tool for the analysis of cultural heritage objects. Although absorption and resolution effects complicate qualitative analysis of the data, layered structures can be distinguished from homogeneous samples without the need for full quantification. Different manufacturing techniques were studied in this work with the help of hand-made reference samples. With the gained knowledge it could be shown for the investigated historical glass object, that black enamel as a stained glass contour colour was used in a cold painting. The object was not fired after the application of the black enamel, but instead the adhesion of the paint was solely provided through organic binding agents and the backing with metal foils. Thus, for the manufacturing of the object, a mixture of cold painting technique with a stained glass color was used. Quantitative measurements with a 3D Micro-XRF setup at the Berlin synchrotron BESSY II confirm the assumptions drawn on the basis of the qualitative investigation with the 3D Micro-XRF spectrometer with X-ray tube excitation.

One the one hand these chemical composition fingerprints may answer some questions concerning the provenance of different materials, the chronology of their use, and give furthermore, the possibility to date unknown fragments in the lifework of an artist. On the other hand this method might be useful for the development and validation of conservation treatments.

The particle number concentration time series was measured as well as the particle size distributions. In parallel, emitted particles were size-selectively sampled with a cascade impactor and subsequently analyzed by the means of XRF. In order to identify potential sources for the aerosol's elemental composition, materials involved in the printing process such as toner, paper, and structural components of the printer were also analyzed. While the majority of particle emissions from laser printers are known to consist of recondensated semi volatile organic compounds, elemental analysis identifies Si, S, Cl, Ca, Ti, Cr, and Fe as well as traces of Ni and Zn in different size fractions of the aerosols. These elements can mainly be assigned to contributions from toner and paper. The detection of elements that are likely to be present in inorganic compounds is in good agreement with the measurement of nonvolatile particles. Quantitative measurements of solid particles at 400 °C resulted in residues of 1.6 × 109 and 1.5 × 1010 particles per print job, representing fractions of 0.2% and 1.9% of the total number of emitted particles at room temperature. In combination with the XRF results it is concluded that solid inorganic particles contribute to LPD emissions in measurable quantities. Furthermore, for the first time Br was detected in significant concentrations in the aerosol emitted from two LPD. The analysis of several possible sources identified the plastic housings of the fuser units as main sources due to substantial Br concentrations related to brominated flame retardants.

Prior to this study, the presence of organochlorinated pesticides in rooms and storage cabinets had already been proven in an analysis of air samples that employed gas chromatography and mass spectroscopy. To estimate the risks these toxins pose to both collections and museum staff, we conducted a field study with the help of a portable X-ray fluorescence spectrometer. In this study, we present an attempt at a reliable quantitative analysis. In addition to chlorine, other potentially hazardous elements such as lead, arsenic, and mercury were found in the majority of the objects. In some cases, however, it has to be taken into account that the detected elements might have originated from manufacturing processes rather than biocide treatments. Such knowledge is a crucial prerequisite to proper risk prediction.
