What is Lead styphnate?

Plain description, key identifiers and synonyms

Lead styphnate, [wetted with >= 20 % water or mixture of alcohol and water] appears as a slurry or wet mass of orange-yellow crystals. Must be shipped wet with at least 20% water or water and denatured ethyl alcohol mixture. May explode due to shock, heat, flame, or friction if dried. Used as an initiating explosive. The primary hazard is the blast of an instantaneous explosion and not flying projectiles and fragments.
