Previous research into bonad painting has always originated in the humanities, from an art/cultural history perspective.
Bonad paintings are painted wall hangings that tell a story, often with a biblical theme, and were put up in farmhouses on special occasions such as Christmas. However, there has, to date, been little information available about the paint and materials used.
“It’s important to know about the materials used in these wall-hangings so that we can preserve them,” says Ingalill Nyström from the University of Gothenburg’s Department of Conservation. “We need to know whether they run the risk of being bleached or broken down by different kinds of exposure, treatment or conservation method. It’s also important for the people who handle them to know whether any of the substances in them could be harmful or toxic.”
Several toxic pigments have been found in the wall hangings studied, including orpiment and emerald green, which contain arsenic. Orpiment was very common in yellow pigment in painted wall hangings throughout the 18th century and well into the 19th century too. Emerald green appears in some 19th century wall hangings.
“So it’s important to be careful when handling them. Several of the pigments and dyes are also sensitive to light, and the binding agent in the hangings is sensitive to damp and moisture.”
Ingalill Nyström’s thesis is the first of its kind. Previous research into bonad painting has always originated in the humanities, from an art/cultural history perspective.
Her aim was to investigate the technology, materials and painting techniques used in the wall hangings.
“The quality and characteristics of the materials used can play a role in both these paintings’ technical opportunities and their limitations. In my book I describe the various raw materials, approaches, potential painting tools and other aids that could have been used,” says Ingalill Nyström.
She also discusses how the paints may have been mixed and applied to the wall hangings.
Ingalill Nyström’s work is a cross-disciplinary study that combines art technological source research with spectroscopic analysis methods. She has examined more than 70 bonad paintings originating from southern Sweden between 1700 and 1870, and also 700 paint samples.
The materials used often comprised paint made with cheap pigments mixed up with egg and sometimes a touch of flour. The paint was generally applied to recycled linen, which had been primed with flour glue. Typically, templates were used for the figures in the scenes depicted.Contact:

Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.
The results will be published on March 22 in the journal „Astronomy & Astrophysics“.

Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.
Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.

Enzymes behave differently in a test tube compared with the molecular scrum of a living cell. Chemists from the University of Basel have now been able to simulate these confined natural conditions in artificial vesicles for the first time. As reported in the academic journal Small, the results are offering better insight into the development of nanoreactors and artificial organelles.
