Prov nr 13 (Sample No. 13) - Analysis Report

This document is a laboratory report from the Swedish National Defence Research Institute (FOA), dated July 25, 1946, concerning 'Sample No. 13'. The report details an incident reported by a stone worker named Hugo Rydén in Löre, Glanshammar, on July 18, 1946. Rydén reported that during the night, two slag-like objects fell onto his property. He claimed the objects were hot upon impact, as the grass surrounding the landing site was scorched. Upon investigation by Constable K.G. Jernwall, a 13x13 centimeter area of burned grass was identified, along with four match-like sticks. The laboratory analysis of the recovered material described two irregularly shaped pieces weighing approximately 20 grams, along with numerous smaller particles. The material was characterized as a brown-black, porous ground mass fused with sand on one side, featuring metallic, drop-shaped deposits. Physical testing revealed that the ground mass was hard but brittle, non-magnetic, and resistant to rusting in water. Conversely, the metallic droplets were magnetic and rusted rapidly when exposed to water.
