Updated April 25, 2017. By Maria Kielmas. Dynamite was invented by Swedish chemist and engineer Alfred Nobel in the late 19th century as a safe way of using nitroglycerin as a demolition agent. Nobel stabilized nitroglycerin by mixing it with diatomaceous earth, the fossilized shells of diatoms. Dynamite has to be detonated using a blasting cap.

The carbon and hydrogen combine with oxygen, and the nitrogen is liberated. Dynamite is an explosive consisting of an absorbent substance (for example, sawdust) soaked in nitroglycerin. The absorbent material helps nitroglycerin become much more stable. You normally use a blasting cap to detonate dynamite — this creates a small …
