AI-Generated Summary
A 1946 laboratory analysis report from the Swedish FOA regarding an unidentified material sample (Prov nr 3:1). The material's origin remained unknown after expert consultation.
This document is a laboratory report detailing the analysis of a material sample designated 'Prov nr 3:1'. The sample was collected on July 9, 1946, and received by the Swedish National Defence Research Institute (FOA) on July 12, 1946. The sample consisted of three pieces, each weighing approximately one gram, and was initially examined by Dr. Bäcklund at the Swedish Cellulose Company's Central Laboratory in Sundsvall. Visual inspection described the material as loose, white to grey-white, and easily crumbled. It contained a mixture of branched and unbranched fibers, crystals, black particles, and brown scales. The material exhibited a layered structure, potentially originally 6 mm thick, with internal cavities lined with a black substance. Chemical analysis showed the material was 90.5% soluble in acetone, with a melting point of +50 degrees Celsius for the soluble portion. Further testing, including saponification, indicated no non-saponifiable matter. A microscopic examination identified a granular structure in the fatty primary component. The report concludes with a note that Dr. Thorslund of the Geological Survey of Sweden was unable to provide any information regarding the origin of the material.
Vid besök på Sveriges Geologiska Undersökning kunde dr Thorslund icke ge någon uppgift om materialets ursprung.

Official Assessment
The material is soluble in acetone (90.5%), insoluble in acetone (9.2%), and contains 1.3% ash. The acetone-soluble portion has a melting point of +50 degrees, a saponification value of 188, and a neutralization value of 198. Microscopic examination reveals a granular structure in the fatty main component. Dr. Thorslund of the Geological Survey of Sweden could not identify the origin of the material.
