Prov nr 18 (Sample No. 18) Analysis Report

This document, dated August 19, 1946, details the laboratory analysis of 'Sample No. 18' (Prov nr 18) conducted by the FOA. The sample was recovered from a site near Torsjö, Eksjö, following a reported light phenomenon observed on August 11, 1946, at 1400 hours. An initial investigation on June 13 (likely a typo in the document for August) at the suspected impact site led to the discovery of slag material believed to be from a space projectile. The material was subsequently sent to Professor Ljundgren at the FOA for analysis. The physical description of the sample notes it consisted of irregularly shaped, grey lumps with white patches, reaching up to half the size of a fist. It was not compact, appearing to be composed of sintered or stuck-together dried powder. Upon heating, the material burned and produced white smoke. Chemical analysis revealed the primary component to be zinc, with trace amounts of lead and cadmium, as well as water-soluble zinc chloride. The report concludes that the presence of zinc powder in this form is difficult to explain in a natural context. By comparing the sample to known unburned smoke mass treated with water, investigators determined that the sample was, in all probability, unburned smoke mass.
