Gelignite

The blasting gelatine ( explosive rubber) is one of the strongest commercial explosives and is one of the dynamite explosives, specifically to the Abelites. The blasting gelatine consists of glyceryl trinitrate ( " nitroglycerine " ) and 6-8% collodion.

First produced in 1876 by ​​Alfred Nobel, to increase the safety in handling of nitroglycerin, it is more efficient. Than ordinary dynamite, which contains about 25 % inert diatomaceous

The detonation velocity of the explosive gelatin is approximately 8,000 m / s; However, blasting gelatine is subjected to a rapid aging process, which greatly reduces the detonation velocity.

The blasting gelatin forms a gelatinous, elastic, translucent, pale yellow colored mass of the consistency of a thick jellied, can be easily bent, cut with a knife and leaves even in the strongest pressure does not spill glyceryl trinitrate.

By adding a little camphor (4 %), it is insensitive to mechanical effects, even against those margins to a large degree. When heated, blasting gelatin behaves similar to the ordinary dynamite. For yourself blasting gelatine explodes on rapid heating at a temperature of about 240 ° C, mixed with camphor can blasting gelatin no longer be detonated by slowly heating. Against water blasting gelatin is so insensitive that they can be stored until use under water.

It is used only in exceptional cases.
