Last weekend I taught a special two-day course on the identification of explosives to a young lady from San Salvador. She is a forensic mrcroscopist newly assigned to the "Bomb Squad". Her problem was to determine what explosives were used after terrorist bombings. Fortunately, some small particles of the explosive substance usually remain after a detonating. Careful examination of a bomb crater or of bomb fragments usually uncovers these tiny residues.

My problem was to teach her the microscopical characteristics of the most likely explosives she might encounter. These include common inorganic nitrates, chlorates and percholorates and less common organic (military) explosives such as TNT, RDX, HMX, PETN and tetryl.
