The more nitroglycerin there is in a given lot of dynamite, the farther back the mortar will swing.
Of course this transportation by flow is possible for nitroglycerin only while it is a liquid, and not after it has been absorbed by porous earth and given the name of dynamite and the look of moist sawdust.
On the other hand, the girls working with cordite get to using it as chewing gum; a harmful habit, not because of any danger of being blown up by it, but because nitroglycerin is a heart stimulant and they do not need that.
Nobel's invention, "cordite," is composed of nitroglycerin and nitrocellulose with a little mineral jelly or vaseline.
Why not solve both difficulties together by dissolving the guncotton in the nitroglycerin and so get a double explosive?
But nitroglycerin is uncertain stuff to keep and being a liquid is awkward to handle.
So instead of throwing away the extra collodion that he had made he mixed it with nitroglycerin and found that it set to a jelly.
Besides cordite and similar mixtures of nitroglycerin and nitrocellulose there are two other classes of high explosives in common use.

A flask of whisky was in another pocket, a bottle of peppermint and tablets of nitroglycerin were in a third, and yet he was really in no shape to go at all.
In this way he obtains a very inflammable and very porous charcoal, which can absorb more than five, and approaching six times its weight of nitroglycerin without any risk of the separation of the oil.
The nitroglycerin in exploding decomposes into steam, carbonic acid, nitrogen, and oxygen.
Some of this glycerin is refined, but the great part of the crude goes to the manufacturers of dynamite, which is nitroglycerin mixed with infusorial earth, so as to weaken it.
There is just as much acid after the glycerin is turned into nitroglycerin as there was before.
In burning the nitroglycerin is protected from detonation by the gelatinous state of the guncotton, but still adds to the rate of burning and produces a higher temperature.
This statement appears to be correct for all kinds of nitrated cellulose powders, whether mixed with nitroglycerin or other substances.
No evidence was submitted that the tablets, as found on the market, contained the amount of sodium nitrite and nitroglycerin claimed.
That is, it does not appear that the manufacturer checks the sodium nitrite and nitroglycerin content by analysis.
The necessity of such control of tablets containing nitroglycerin is evident from the report[102] of L.

Therefore when nitroglycerin is indicated to lower blood pressure, digitalis is not usually indicated; when digitalis is indicated to aid the heart, nitroglycerin is generally not indicated.
The treatment of such an undesired behavior of digitalis is, of course, to stop the drug immediately, give saline laxatives, hot sponging or hot baths, nitroglycerin and perhaps alcohol.

Poisonous fumes are often produced by the explosion of the nitroglycerin compounds.
This name was originally applied to his mixture of nitroglycerin with kieselguhr, but now includes also other mechanical mixtures or chemical compounds which develop a high explosive force as compared with gunpowder.
These are probably largely due to incomplete detonation, by which part of the nitroglycerin is vaporized or merely burned.
Nitroglycerin in its liquid form is now rarely used for blasting, partly because its full strength is not often necessary but chiefly because of the difficulty and danger of transporting, handling and charging it.
