Teknisk analys av konst på papper -Exemplifierad genom undersökning av träsnitt
The aim of this bachelor thesis has been to investigate some of the materials present in and onprinted papers which might be suitable for analysis. A brief history of paper making and somepigments were studied after which the theory of some of the available methods for technicalanalysis were summarized. Two works of art on paper were chosen for a closer examination,both are woodblock prints but of different composition and origin. The investigation wasmade to exemplify some of the common techniques applied on works of art. There were twoaims in these examinations. One was to extract sufficient information about the objects so thata decision about possible measures in conservation can be supported or avoided. The otheraim was to try and extract enough useful information from the objects so that a determinationof age and attribution either could be supported or rejected. The two most advanced analyticalinstruments used in the study were FTIR and SEM-EDX. An evaluation of the application ofthese for pigments and a specific dye on paper was made. The conclusion of this was that thelack of references for the comparison of results was one of the main limiting factors. Eventhough a definite result wasn't achieved, the study showed that one possibility to determinepossible presence of the moisture sensitive dye dayflower blue (commelinin) was throughexamination with SEM-EDX. The way in which this was done with the equipment used wasto determine the presence of the element magnesium. Further studies would include whether anon-destructive method of determining the presence of this dye could be performed using aXRF equipment.
