Dynamite is an explosive material based on nitroglycerin, using diatomaceous earth (AmE: kieselgur; BrE: kieselguhr), or another adsorbent substance such as powdered shells or clay. Dynamites using organic materials as sorbents such as sawdust are less stable and such use has been generally discontinued. Dynamite was invented by the Swedish chemist and engineer Alfred Nobel in Geesthacht, Germany, and patented in 1867.
