Abstract [en]

Paint fragments were collected from painted 18th and 19th century interiors from traditional buildings in Halsingland, Sweden. The aim was to identify binders used by the artists by direct-methylation and GCMS analyses of the lipid fraction in the samples. The lipid content was categorized as mainly animal, plant-based or mixed. The study indicates that used colour tone and possibly also underlying foundation (wood, paper or textile) is essential for the artists' choice of binder components. Animal-lipid based compounds were found to be used for a wide variety of colours, including mixed colour and several light colour tones. Animal and sometimes mixed lipids seem also to be characteristic for colour fragments from paper and textiles. Red, black and blue colours are quite common among the mixed-lipid category. However, half of blue, green and black colours were found in the vegetable lipid group. A tendency towards the plant-lipids was also indicated in colour samples painted on wood. Many different forms of terpenoids were found among the wood samples, suggesting that its origin can be traced mainly to wood composites, such as extractives.
