Analysis report from the project "Drawings by Johan Tobias Sergel at Nationalmuseum", RAÄ-2023-2835

Analysis report from the project "Drawings by Johan Tobias Sergel at Nationalmuseum" (Diarienummer RAÄ-2023-2835). This report compiles data from the following analytical techniques: 1. X-ray fluorescence spectroscopy (XRF; data from a Bruker Artax u-XRF and Bruker Crono MA-XRF); 2. Fourier transform infrared spectroscopy (FTIR). The purpose of the project was to better understand the composition of Hetsigt Kärlekspar, a drawing by Johan Tobias Sergel (https://collection.nationalmuseum.se/en/collection/item/71030/), particularly the ink and the residual adhesive from the lining, which could 
perhaps lead to a better understanding of the fragile nature of the drawing and its deterioration processes.
