Dynamite is an explosive made of nitroglycerin, an adsorbant (usually diatomaceous earth) and various stabilizers. It is the first high explosive developed, and it replaced gunpowder in many applications.
Dynamite will burn if ignited, but if the flame is too hot, it may explode.
Dynamite is a white-grayish paste, insoluble in solvents (the filler part). Dynamite has a density between 1.30 - 1.51 g/cm3.
Dynamite is a strong explosive, which is sensitive to shock, such as impact. It has an average detonation velocity of 6,000 m/s.
Few places still manufacture dynamite in its classical version, as most have switched to the more safe ANFO based explosives. Dyno Nobel is one of the few that still produce it. Purchasing it requires an explosive permit.
Dynamite can be prepared by carefully adding nitroglycerin to powdered diatomite.
Dynamite is best used as a way to safely handle and detonate nitroglycerin.
Working with dynamite will result in absorbing nitroglycerin liquid/vapors, which, being a strong vasodilator, will result in severe headaches.
Dynamite is best stored in cool places. It can only be stored safely for about 1 year. Over time, it will "sweat" nitroglycerin, which is very dangerous.
