   Sammanfattning : The number of publications concerning problems with pyrit (FeS2) and pyrite oxidation in archaeological objects made of bone or antler is limited. Problems with oxidation of unstable pyrite are well known in mineral collections, marine archaeological wood as well as archaeological skeletal remains. LÄS MER

3. 2. Färgerna i Torpa geometrisk jordebok Materialundersökning av en samling lantmäterikartor från 1640-talet

   Kandidat-uppsats, Göteborgs universitet/Institutionen för kulturvård

   Författare :Kristina Nilsson; [2015-01-08]
   Nyckelord :pigment analysis; FTIR-spectroscopy; SEM-EDX-spectroscopy; geometrical cadastre; 17th century cadastral map; Nils Eriksson Njurén;

   Sammanfattning : The geometrical cadastre of Torpa, drawn by Swedish surveyor Nils Eriksson Njurén in 1648, was analyzed by micro-sampling Energy-dispersive X-ray (SEM-EDX) and Fourier transform infrared (FTIR) spectroscopy, in order to characterize the materials used in its production. The volume is one of the old Swedish geometrical (large-scale) cadastres that were produced during the period 1630-1655, with the purpose to gain insight of the resources of the country. LÄS MER
