AI-Generated Summary
A 1946 laboratory report from the Swedish FOA analyzes a 4.5g iron-based object (Sample 11). Experts from the Swedish Museum of Natural History determined the object was not a meteorite, identifying it instead as an industrial byproduct.
This document is a laboratory report from the Swedish National Defence Research Institute (FOA) regarding 'Sample No. 11,' which was received on July 22, 1946. The sample, weighing 4.5 grams, was submitted in a glass tube with a cork. Physically, the object was described as a small, flattened drop-shaped piece with smooth surfaces. Upon arrival at the FOA, it had broken into several smaller pieces. The material exhibited a sintered structure, with a radiated structure on the side that had contacted a surface, and a porous structure elsewhere. The sample was found to be magnetic. Chemical analysis of three samples yielded an average iron content of 75.6%, with no other metals detected, suggesting the object was a mixture of magnetite and free iron or iron oxide. Spectroanalytical examination confirmed iron as the primary constituent. To determine its origin, the sample was presented to Professor Aminoff and Dr. Zenzén at the Mineralogical Department of the Swedish Museum of Natural History. They concluded that the object could not be a meteorite, noting that while iron meteorites contain iron, they typically also contain significant amounts of nickel and iron sulfide, and possess a completely different structure. The report concludes that the sample is a product of some industrial process.
Vid besök på Naturhistoriska Riksmuseets Mineralogiska Avdelning förevisades provet för professor Aminoff och dr Zenzén, vilka intygade, att det icke kunde utgöras av en meteorit.

Official Assessment
The sample is not a meteorite; it is likely a product of some industrial process.
Chemical analysis showed 75.6% iron content with no other metals present. It is likely a mixture of magnetite and free iron or iron oxide. Experts at the Swedish Museum of Natural History confirmed it is not a meteorite due to its structure and lack of nickel/iron sulfide.
