Offre de thèse : Reproduction and chemical characterisation of historical lead white (Antwerp)

Logo University of Antwerp

The research groups Antwerp Cultural Heritage Sciences (ARCHES) and Antwerp X-ray analysis, Electrochemistry and Speciation group (AXES) of the UAntwerpen are looking for a joint full-time (100%) doctoral candidate in the interdisciplinary field of Conservation-Restoration (C-R) and Science, focussing on the reproduction and chemical characterisation of historical lead white, to explore its potential to serve as a technical marker for dating paint layers. You will work actively on the preparation and defence of a PhD thesis dedicated to the study and characterisation of historical lead white in paintings with the aim to discriminate pigments employed by Old Masters from their industrial-age equivalents. To do so, your work will focus on the study of historical textual sources and the reproduction of historical technology, followed by the speciation and quantification of the resulting substances with chemical imaging and other techniques. In this way, your research is anticipated to assist the (ongoing) treatment of hybrid artworks in museum galleries, presenting heritage professionals with a puzzling amalgam of original materials and non-original layers, accumulated during various interventions.
