Explosive Dynamite Britannica

Explosive Explosive Dynamite: The second most important of Nobel’s inventions was dynamite, in 1867. He coined the name from the Greek dynamis, “power.” The basis for the invention was his discovery that kieselguhr, a porous siliceous earth, would absorb large quantities of nitroglycerin, giving a product that was much safer to handle and easier to use than nitroglycerin alone.
