Dynamite is an explosive made of nitroglycerin, sorbents (such as powdered shells or clay) and stabilizers. It was invented by the Swedish chemist and engineer Alfred Nobel in Geesthacht, Northern Germany and patented in 1867. It rapidly gained wide-scale use as a more powerful alternative to black powder. Today, dynamite is mainly used in the mining, quarrying, construction, and demolition industries. Dynamite is still the product of choice for trenching applications, and occasionally used as a cost-effective explosive booster for ANFO charges.
