Talk:Dynamite

message: This is all well... and good, and has proven to provide the user with interesting information.   May I suggest adding a "How-To"  section to the article ?  (I am not fluent enough with this topic to write it)  
I'm considering playing around with different chemical compositions and thought that it might be interesting to see household items which might provide the proper components for something of this nature.
Perhaps outside the realm of a traditional Encyclopedia, but I figure I'd comment and see if anyone has anything to say / add.

:This is also my understanding.  Although "dynamite" originally referred to nitroglycerine in diatomaceous earth, today commercial "dynamite" is made of mixtures containing mostly ammonium nitrate.  It's still packed in the familiar red* tubes. -Wfaxon 04:22, 16 July 2006 (UTC)

11/20/06 - This may be the wrong place to post such a comment/question, but I was watching a movie last night that the actors found a couple of sticks of Dynamite in a freezer and one of the actors stated that once the dynamite dropped 3 degrees it would explode.  I noticed this post stated that the Nitro within Dynamite is volatile when frozen so it seems there is partial truth to this but is it true about the degree drop causing it to explode.  They were stating only a fool would store dynamite in a freezer which it appears to be true.  And no I do not have dynamite much less in my freezer, I just from time to time like to see if what someone says is true is so based on some type of data.  Thanks and please feel free to send me an email at pjhinde@aol.com if you have data or post it here.

Just corrected your spelling. Nitroglycerine is safe to handle when Absolutely frozen,  below about 56 Fahrenheit, but, on thawing, large ice crystals with sharp edges break loose, causing extreme shock sensitivity until fully thawed.  There should be a section on this unfortunate property, and how antifreezes, like Ethylene Glycol Trinitrate, prevent this and also add to the blast. Also, Nitro's reputation for the Worst Headaches. Miners would chew a piece of dynamite or stick it in their sweatband to get used to it. If you stop being exposed, the headache tendency also returns,70.176.118.196 (talk) 20:23, 25 March 2011 (UTC)

thread_title:  Incorrect content? 

message: Is it not true that sawdust can be used as a replacement for the diatomacious earth? I.E, mixing sawdust and nitroglycerin can also create dynamite, correct?
* Nitroglycerine based dynamite has been made mixing dynamite with sawdust, with sawdust and nitrates to burn the sawdust, with ammonium nitrate which is another explosive itself. Diatomacious earth is inert and served to cushion the nitroglycerin which is sensitive to shock. The other substances used to make other variaties of dynamite are either explosives themselves or fuels that add to the explosive effect while also serving to cushion the nitroglycerin against shock. Common commercial dynamite was usually made to be used in an on-going mining or quarry operation and was not intended to be stored for long because time or extremes of weather can seperate the volatile nitro from the cushioning material (see the plot of the movie "Sorcerer (film)").

message: :Nobel later on deeply regretted his inventing of the explosive due to its use on the battlefield as a means of killing. This led him to use the great fortune dynamite brought him to fund the Nobel Prize.[citation needed]
At least the German Wikipedia states that, despite frequent claims to the contrary, the classical (Gur-)dynamite was never used in battle because it was too sensitive at this point. (Entgegen vielfacher Behauptung wurde das klassische (Gur-)Dynamit Alfred Nobels nie im Krieg verwendet, da es zu diesem Zweck noch viel zu empfindlich war.) So what is true? Was some variety of dynamite used? Which variety? Did this really motivate Nobel to fund the Nobel Prize? (Why then are there prizes for physics or chemistry?)

thread_title:  Dynamite has Greek and not Latin Roots 

message: It should be noted Nobel called his powder "Dynamite" from the outset. Some countries, like England, nicknamed it "Nobel's  Safety Powder". A record of the accidents from straight nitroglycerin should precede Nobel's discovery, giving it more merit.
The first dynamite company was in San Francisco, CA, about 1867. In order to circumvent Nobel's patent, it was soaked in wood pulp, etc, not kieselguhr, as the patent stated.  This was Giant Powder Company; the name "Giant Powder" became an American generic for Dynamite (a copyrighted term).  Hercules, in the East Bay,  followed. After several explosions , Giant  and Hercules were absorbed by DuPont. Giant moved back east to Wilmington,  Delaware. Hercules manufactured dynamite, then  nitrate fertilizer. then imported it, before going out of business. Du Pont bought out many firms. In 1911, after the Sherman Anti Trust act, DuPont had to release its near stranglehold on dynamite manufacture in the U.S.
Du Pont, oddly, had  initially resisted the manufacture of dynamite, spreading propaganda it was "unsafe". Peddlers would show sticks to miners, then set them on fire,  hit them with hammers,etc,  to prove it was ok. They even gave away  free samples to anyone who'd try it. None was made on the east coast until  DuPont's  Repauno plant opened in 1886. Then, the buy-outs began.
The only dynamite mfgr. in the U.S. to date is Austin Powder in Cleveland, OH. Du Pont now  only manufactures paints and chemicals. Apache Powder, near Tucson, AZ, only mfgs. Ammonium Nitrate, and wholesales explosives. This is mostly due to nitrate pollution into the artesian aquifers of the surrounding cities of Benson, Curtis, St. Davids, and Tombstone. There are several Canadian, Indian, European, and South African concerns still going. Dynamit Nobel is the best known.
Dynamite made silver, nickel, and other metals we take for granted now commercially available. The depth and hard rock of the Comstock Lode made its mining nearly  impossible until its invention.   Black powder was cheaper, but it took seven to nine times as much. Large holes had to be made to place the kegs. Due to its low briscane (shattering power), black blasting powder would only break rocks to boulder-sized pieces, making  for more work. Dynamite, though more expensive, was much cheaper to use as it used less, and shattered rocks to bits. Silver prices soared until its general use. (The "Cartwrights" on the TV show, Bonanza, owe their fortune to the Comstock Lode and Dynamite. The initial airings are dated around 1867.)It also made mining of the Anaconda range in Montana possible and profitable. Many alloys that build our jet aircraft, etc, are made so because of hi explosives like dynamite used in mining.70.176.118.196 (talk) 00:37, 26 March 2011 (UTC)

thread_title:  First man to use Dynamite in rock blasting? 

message: I was going to make an article about this explosive substance but after reading this article I'm not too sure about it now. According to the dynamite article, dynamite was invented in 1867 and is based on nitroglycerin and sawdust or wood pulp can be used. But according to this 1870 book, dualin was invented in 1869 and took the place of nitro-glycerine and dynamite. The dictionary definition of dualin is "an explosive substance consisting essentially of sawdust or wood pulp, saturated with nitroglycerin and other similar nitro compounds. It is interior to dynamite, and is more liable to explosion." I don't know much about explosives but to me it sounds like the WP dynamite article has a confusion with dualin: using nitroglycerin, sawdust or wood pulp to make dynamite. It would be nice if this could be cleared up. Volcanoguy 15:05, 4 May 2013 (UTC)
replies: text: You don't seem to have read your source correctly. Its a book dated 1870 refering to Mining and Mines in the USA. Dynamite, at that time, was a registered trade name and refers to particularly product manufactured by a particular company which was sold in certain countries: mostly in the UK, South Africa and Australia, but also the USA. Its not in the dynamite article but there was a recognised explosives cartel where Alfred Nobel, in Britain, and the German explosives manufactures carved up the world trade in explosives between themselves. Dualin is another (possibly) similar product with a registered trade name that appears to be common in the USA and Germany. So what what gives you the expertise to claim that the wikipedia article on dynamite is confused: it is not? Dualin, appears to be an inferior and less safe product, which your source clearly states. It was possibly used in the USA because it was cheaper than Dynamite, which would have to have been imported in the USA via one of Alfred Nobel's official agents, and it was possibly a way of getting around Nobel's US trade marks / patents.

text: Dualin was also used in Canada because I have read about its use at an early 1900s mine in my area. Volcanoguy 17:25, 5 May 2013 (UTC)
replies: text: Thanks for that. I did some more (quick) research on this topic from a UK perspective and there are a few points that I could add. I also picked up a copy of "The Du Pont Canada History", written in 1982, when I was in Ottawa four years ago, so I know that Canada was making black powder (Gunpowder) from 1860 onwards, but I don't think it was making any high explosives in the 19th century. I don't really know about Canadian explosives legislation, but from a UK perspective, explosive regulations in effect banned the manufacture, importation and use of all explosives except those on a list of authorised explosives. Canada might have had similar laws. These lists included many (comparable) trade name explosives. Nobel's UK patent on Dynamite No. 1 expired in 1881, so after that anyone could make it, and that could/would have lead to a fall in price. To get round that a Nobel-Dynamite Trust was in operation between 1880 and 1887, between British and German manufactures, to control prices (and trading areas) across most of Europe and Australia and South Africa. In 1897 there was a similar-type agreement set up between the Nobel-Dynamite Trust and du Pont, in America, and that lasted until 1907. Canada had very high import duties on American explosives (to price out US manufacturers) and that seems to have lasted until 1906, when Canada became a free trade area (for explosives). If as you say Dualin was in use in Canada about 1900, then it might well have been imported from Germany. Canadian Explosives Ltd was set up in 1911 (see Nobel, Ontario), so from about World War One, onwards, Canada had a domestic supply of high explosives. Albeit, the company had US and British owners (du Pont and ICI)Pyrotec (talk) 19:12, 5 May 2013 (UTC)
replies: text: The year was 1908 when the mine was using it. The document I read was about two miners who got killed by a charge of dualin. Apparently the charge only partly exploded so the miners were trying to clean the blast hole out and reload it. But the rest of the charge exploded while cleaning it out, killing the two men and injuring three others. Anyway I just think there should be an article for dualin. There seems to be no articles mentioning dualin but it can be added in  under blasting since it was used for blasting rock. Volcanoguy 21:00, 5 May 2013 (UTC)

message: Both articles will have this exact message added to their talk section. The explosive yield of both TNT and Dynamite are cited as different values in their respective articles, and as multiple different values within a single article. The Wikipedia article on Dynamite (http://en.wikipedia.org/wiki/Dynamite) cites TNT and Dynamite to have explosive yields of 4.0 MJ/kg and 5 MJ/kg, respectively, whereas the Wikipedia article on TNT (http://en.wikipedia.org/wiki/Trinitrotoluene) cites TNT and Dynamite to have explosive yields of 2.8 MJ and 7.5 MJ/kg, respectively. In the TNT article, there is a line, "The explosive energy utilized by NIST is 4184 J/g (4.184 MJ/kg).[16]", which probably means to say that TNT has an explosive yield of 4.184 MH/kg, making for a probable third value, but the statement is ambiguous: On first read, I thought that NIST was an explosive that produced 4.184 MJ of explosive energy for every kg utilized. Suggest changing it to something like, "The NIST records the explosive yield of TNT as 4.184 MJ/kg.", if that is what is actually meant.  — Preceding unsigned comment added by 174.3.225.120 (talk) 00:34, 28 July 2014 (UTC)

message: FWIW, I remember reading an article (in Science I think) some years ago which stated that, while dynamite certainly revolutionized hard rock mining and demolition, Nobel's biggest customers were American farmers, who used it to clear their land of stumps. The eastern half of the US was originally mostly forest, which had to be cleared to facilitate plowing. That is a lot of stumps. While you can easily uproot stumps now with machines, at the time it was quite difficult, and dynamite solved a major problem for farmers.
