At the time, the only dependable explosive for use in mines was black powdera form of gunpowder. A recently discovered liquid compoundnitroglycerinwas a much more powerful explosive, but it was so unstable that it could not be handled with any degree of safety.

In Nobel invented an improved detonator called a blasting cap ; it consisted of a small metal cap containing a charge of mercury fulminate that can be exploded by either shock or moderate heat.

The invention of the blasting cap inaugurated the modern use of high explosives. Nitroglycerin itself, however, remained difficult to transport and extremely dangerous to handle. Undaunted by this tragic accident, Nobel built several factories to manufacture nitroglycerin for use in concert with his blasting caps.

These factories were as safe as the knowledge of the time allowed, but accidental explosions still occasionally occurred.

By chance, he discovered that nitroglycerin was absorbed to dryness by kieselguhra porous siliceous earth, and the resulting mixture was much safer to use and easier to handle than nitroglycerin alone. He also continued to experiment in search of better ones, and in he invented a more powerful form of dynamite, blasting gelatinwhich he patented the following year.

Again by chance, he had discovered that mixing a solution of nitroglycerin with a fluffy substance known as nitrocellulose results in a tough, plastic material that has a high water resistance and greater blasting power than ordinary dynamites.

In Nobel introduced ballistiteone of the first nitroglycerin smokeless powders and a precursor of cordite. Although Nobel held the patents to dynamite and his other explosives, he was in constant conflict with competitors who stole his processes, a fact that forced him into protracted patent litigation on several occasions.

Besides explosives, Nobel made many other inventions, such as artificial silk and leather, and altogether he registered more than patents in various countries. Although his business interests required him to travel almost constantly, he remained a lonely recluse who was prone to fits of depression.

He led a retired and simple life and was a man of ascetic habits, yet he could be a courteous dinner host, a good listener, and a man of incisive wit. He never married, and apparently preferred the joys of inventing to those of romantic attachment.
