Analysis of Unknown Material Sample, July 1946

This document details the technical analysis of an unidentified material sample conducted between July 13 and July 15, 1946. The investigation involved consultations with experts at the Geological Survey of Sweden (Sveriges Geologiska Undersökning), the Royal Institute of Technology (Tekniska Högskolan), and the company AB Wilh. Becker. The sample was initially hypothesized to be an industrial waste product altered by atmospheric conditions. Dr. Thorslund of the Geological Survey dismissed the possibility that the sample was a fossil or recent resin, suggesting it might be cellulose industry waste. Docent E. Öman, an expert in paper technology at the Royal Institute of Technology, examined the sample and found no evidence of cellulose industry waste. He noted a potential similarity to a nitration product of retene. Subsequent testing with concentrated nitric acid, however, failed to dissolve the sample, which instead turned black. Docent Öman also considered the possibility of discarded linseed oil but could not explain the material's unique structure. Finally, discussions with Engineer Klang at AB Wilh. Becker on July 15, 1946, involved comparing the sample against known resins, including copal, dammar, and akaroid resins. It was concluded that the sample did not match any known resins or technical products, leaving its origin unidentified.
