War sand

War sand is sand contaminated by remains of projectiles used in war. This kind of sand has been found in Normandy, since its invasion, among other places.^[1] In 1988, the sand on Omaha Beach was discovered to contain man-made metal and glass particles deriving from shrapnel; 4% of the sand in the sample was composed of shrapnel particles ranging in size between 0.06 millimetres (0.0024 in) and 1 mm (0.039 in).^[2] Researchers also discovered trace amounts of iron and glass beads in the sand, originating from the intense heat unleashed by munitions explosions in the air and sand.^[2][3]
