Dynamite was the first trade name introduced for a commercial explosive
by Alfred Nobel; it was nitroglycerine absorbed in kieselguhr
(Guhr dynamite). Bonding of nitroglycerine by gelatinization with nitrocellulose
was discovered by Nobel at a later date.
At first, active absorbents such as a mixture of sodium nitrate with
wood dust were employed instead of the inert kieselguhr. The result
was the development of nitroglycerine-sensitized powdery explosives,
which are still known as “dynamites” in English-speaking countries;
W also Ditching Dynamite.
Variations in the concentration of gelatinized nitroglycerine (the concentrated
product is known as blasting gelatine) by the addition of
sodium nitrate and wood dust or cereal meal yielded gel dynamites,
which are known as “gelignites” in English-speaking countries; in
Germany, the old designation of “dynamite” has been retained. In the
meantime, they have been placed by ammonium-nitrate-based W Ammongelit.
These products contain nitroglycol rather than nitroglycerine,
with improvement in the safety of handling and transportation.
Dynamites are no longer manufactured in Germany.
