Technical Analysis of Recovered Material

This document is a technical report detailing the analysis of recovered physical materials. The items described include a piece of loose-mesh fabric similar to surgical gauze, cotton yarn with black insulating beads, and a crumpled piece of paper identified as being torn from an envelope. The report details a qualitative spectral analysis performed on three samples. Sample 1 contained carbon, silicon, magnesium, iron, aluminum, copper, and traces of zinc. Sample 2 contained manganese, zinc, silicon, magnesium, and iron; dissolution in hydrochloric acid produced chlorine gas, suggesting the presence of manganese dioxide (brunsten), along with graphite residue. Sample 3 contained light-colored salt crusts with zinc as the primary component. Based on these findings, the report concludes that the materials are remnants of a dry cell battery. On July 9, an engineer named Nordin at Rylander & Rudolph Fabriks AB in Henriksdal was consulted. Nordin confirmed the assessment, stating his firm conviction that the items were remnants of a ring-type battery element.
