What is Dynamite?
Classic dynamite is made up of three parts nitroglycerin, one part diatomaceous earth and a small part of sodium carbonate. This is mixed together and molded into short sticks then wrapped in paper. Nitroglycerin on its own is a very explosive substance and is shock sensitive. Absorbed into diatomaceous earth or sawdust, nitroglycerin is less shock-sensitive. Over time, the dynamite will weep its nitroglycerin, which can then pool in the bottom of the box or storage area.
