3. INTRODUCTION
• Dynamite is an explosive made of nitroglycerin, sorbents (such as powdered
shells or clay) and stabilizers.
• It was invented by the Swedish chemist and engineer Alfred
Nobel and patented in 1867. It rapidly gained wide-scale use as a more
powerful alternative to black powder.
• Today, dynamite is mainly used in the mining, quarrying, construction,
and demolition industries.
• Dynamite is occasionally used as an initiator.

4. DYNAMITE
A .Diatomaceous earth
(absorbent material) soaked
in nitroglycerin.
B.Protective coating
surrounding the explosive
material
C.Blasting cap.
D.Electrical cable (or fuse)
connected to the blasting cap.

5. Short Biography Of Alfred Noble
• The Alfred Bernhard Nobel ( 21st Oct 1833 – 10th Dec 1896)
was a Swedish businessman, chemist, engineer, inventor.
• When Alfred was 18,he went to The United States to study
chemistry for 4 years.
• Alfred,returning to Sweden with his father after the bankruptcy
of their family business, devoted himself to the study of
explosive.
• He did this because he builts bridges & building in Stockholm
and his construction work inspired him to research new way of
blasting rocks.

6. Historical Development
• Dynamite was invented by
Swedish chemist Alfred Nobel in
the 1860s and was the first safely
manageable explosive stronger
than black powder.
TIMELINE

7. 1846-Nitroglycerin
• Before Dynamite, Nitroglycerin was first invented
by Italian chemist “Ascanio Sobrero”in 1847.
• It was the first practical explosive stronger than
black powder.
• Sobrero first called his discovery “pyroglycerine”
& warned strongly against its use as an explosive.
• It was later adopt by Alfred Noble as a
commercially useful explosive.

8. 1860- Alfred begins his experiment
• Alfred Noble begins experimenting
with Nitroglycerin. His goal is to
make it a lot more safe & easy to
handle.

9. 1863-Starts Inventing Parts
• In 1863, Alferd Noble invented the Noble patent detonator and blasting caps
for detonating nitroglycerin.
• The Noble patent detonator used a strong shock rather than heat
combustion to ignite the explosive.
• The Noble company built the first factory to manufacture nitroglycerin and
eventually dynamite.

10. 1866-The Invention Of Dynamite
• After years of hard work and research, Noble discovered that mixing
nitroglycerin with silica & sodium carbonate would turn the liquid in
malleable paste called “Dynamite”.
• He originally sold his Dynamite as “Noble’s Blasting powder”.
• After its introduction, dynamite rapidly gained popularity as a safe alternative
to gunpowder & nitroglycerin.
• One advantage that dynamite had over nitroglycerin was that it could be
cylinder-shaped for insertion into the drilling holes used for mining.

11. 1875-Gelatinous Dynamite
• Noble’s next outstanding contribution was his
invention Gelatinous dynamite, an explosive jelly.
• It was more powerful & even a little safer than
dynamite he had invented nine years earlier.
• The addition of ammonium nitrate to dynamite
further decreased the accidental explosions
• It also made it cheaper to manufacture.

12. 1880’s Military Application
• In the 1880’s ,the U.S. Military
experimented with dynamite guns in which
dynamite was fired at the enemy from guns.
However, the concussion from the blast of
the gun prematurely detonated the
dynamite. Other explosive application at
this time had been developed, and the use
of dynamite was minimized.

13. Dynamite Today
• Alfred Noble died in 1896.
• He helped industrialize the world, make many industries safer, and also
changed weapon technology.
• Without Alfred Noble and his dynamite, many more people would have died
when building dams, mining, excavation and demolition.
• In the 1950’s , 95% of the explosive in The United States were dynamite.
Today it’s less than 2%.

14. Noble Prize Initiation
• The Nobel prizes were established by none other than
inventor Alfred Nobel.
• The award is based on a donation received by the Nobel
Foundation in 1968 from Sveriges Riksbank on the
occasion of the bank’s 300th anniversary.
• Initiation of Nobel prize On 27 November 1895, Alfred
Nobel signed his last will,giving the largest share of his
fortune – more than SEK 31 million (today approximately
SEK 1,702 million) to be converted into a fund and
invested in “safe securities”.
