Colorful wall hangings contain toxic substances
Date:11/12/2012

"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 Nystrm.

She also discusses how the paints may have been mixed and applied to the wall hangings.

Ingalill Nystrm'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.
