Sammanfattning (abstract):
The aim of this paper is to highlight various pigments found in 70 signed painted wall-hangings, so-called bonader, produced in southern Sweden during the eighteenth and nineteenth centuries. The analyses were performed using Fourier transform Raman (FT-Raman) spectroscopy and scanning electron microscopy-energy dispersive X-ray analyses, supplemented with microscopy and reconstructions of historic pigment references. The results indicate that inexpensive pigments such as chalk, woad, orpiment, ochres, red lead, and carbon black were used. Some synthetic pigments such as Prussian blue, emerald green, and chrome yellow were used for painted wall-hangings in the latter part of the period. Also some atypical artists' painting materials such as a yellow lake made of curcuma, turmeric, and metallic lead foils were identified. FT-Raman spectra of a selection of pigments used for the wall-hangings are presented. The results from the study can be used for risk assessment for the deterioration of the wall-hangings in consideration of preventive and remedial conservation strategies. The art technological results, i.e. the painting materials found and the different painting techniques identified for each painter, can supplement previous stylistic attributions of unsigned and anonymous painted wall-hangings from southern Sweden.
