Prov nr 4 (Sample No. 4) Analysis Report
AI-Generated Summary
This report details the laboratory categorization of physical samples received by FOA,1 in July 1946. The samples, which include slag-like and coke-like materials, were analyzed for their physical structure and density.
This document is a technical report from FOA,1 regarding the analysis of physical samples received on July 12, 1946, which had been collected on July 9, 1946, and forwarded by the newspaper Sundsvalls tidning. The material arrived in a cardboard box and consisted of numerous pieces of varying sizes. The report categorizes these pieces into four distinct groups based on their physical properties. Group 4:1 contains a single piece similar to 'sample no. 1', which notably contained a piece of grass inside an internal cavity. Group 4:2 consists of relatively heavy, slag-like pieces in colors including violet, brick red, and gray-black. These pieces exhibit a coarse-porous structure with elongated pores, suggesting they were once in a molten or semi-molten state where air bubbles moved in a specific direction. Group 4:3 contains coke-like pieces with a non-uniform structure; some are porous, while others are denser and layered. Some of these pieces have rounded surfaces, indicating they were worn down by rolling against similar materials. These pieces are light and float on water. Group 4:4 is similar to group 4:3 but possesses a more silver or tin-like luster and potentially higher density in its porosity. These pieces also float on water.

Official Assessment
The samples were categorized into four groups based on their physical characteristics, including porosity, color, and density. Observations suggest some materials were in a molten or semi-molten state during formation, as evidenced by the movement of air bubbles. Some samples show signs of mechanical wear, and several are light enough to float on water.
