Mr de la Place and I deflagrated a convenient quantity of nitre and charcoal in an ice apparatus, and found that twelve pounds of ice were melted by the deflagration of one pound of nitre.
The deflagration begins, and continues in the water, and gas is disengaged with less or more rapidity, in proportion as the mixture is more or less dry.
In deflagration with nitre, azotic gas is likewise disengaged, because azote is one of the constituent elements of nitric acid.
It is very probable that water is decomposed during the deflagration of gun-powder, and that part of the oxygen furnished to the nascent carbonic acid gas is produced from it.
After this, the gas of the deflagration is made to pass into the jar in the same manner as directed when water is employed.
As oxygen is changed, by deflagration with charcoal, into carbonic acid, instead of oxygen gas, carbonic acid gas is disengaged, at least when the mixture has been made in just proportions.
So long as the deflagration continues, the muzzle of the pistol must be kept somewhat inclined downwards, to prevent the water from getting into its barrel.
I have already made a considerable series of experiments upon the nature of the elastic fluids disengaged during the deflagration of nitre with charcoal and sulphur; and have made some, likewise, with the oxygenated muriat of potash.
In this manner I have sometimes collected the gas produced from the deflagration of an ounce and half, or two ounces, of nitre.
By igniting the suspected substance with nitrate of potassa, it can quickly be ascertained whether it is organic or not, for if the latter, the vivid deflagration will indicate it.
If the oxidation is effected through the addition of a substance containing oxygen (for instance, the nitrate or chlorate of potash) and the heating is accompanied by a lively deflagration and crackling noise, it is termed detonation.
A mixture of nitre and crude antimony projected into a red-hot crucible, produces a deflagration more or less rapid, forming a composition which is used in pharmacy, and medicine.
We know that carbon has the property of decomposing nitric acid, and also nitrate of potassa; for, when it is brought in contact in the state of ignition with nitre, a deflagration will ensue, and carbonic acid be formed.
The Nitrous Acid is not only dissipated during the deflagration of the Nitre, but is even destroyed, and perfectly decomposed.
When no deflagration ensues, the matter contained in the crucible will have lost much of its fluidity.
This deflagration of Sulphur is the only means we have of decomposing it, in order to obtain its Acid in purity.
In this deflagrationthe Acid is dissipated, and totally separated from the Alkali, which now remains by itself.
The little hole left in the covering crucible is necessary for giving vent to the vapours, which rise during the deflagration of the Nitre, as they would otherwise open themselves a passage by bursting the vessels.
It causes a powerful deflagrationwhen thrown upon burning coals; and when a mixture of it with sulphur is thrown into a red-hot crucible, a very vivid light is emitted.
If nitrate of potash (saltpetre) is the adulterating ingredient, it may be detected by throwing it on burning coals, when deflagration will ensue.
White flux is the residuum of the deflagration in a red hot crucible, of a mixture of two parts of nitre, and one of cream of tartar.
Its opponents even assert that the power and the rapidity of the deflagration of the explosive mixture are greater with hot-tube ignition.
The fifth record is particularly interesting because it shows the influence of the ignition-tube on the power of the deflagration of the explosive mixture (Fig.
Therefore the volume of powder is to the volume of gas produced by its deflagration as 1 to 400.
In order not to pass the weight assigned the sides had been made a little less thick and the bottom thicker, as it would have to support all the violence of the gases developed by the deflagration of the pyroxyle.
The admirable projectile was not hurt by the intense deflagration of the powders, instead of being liquefied, as it was feared, into a shower of aluminium.
It seems to me, too, that that deflagration has the intensity and brilliancy of objects the combustion of which is produced in pure oxygen.
These fusees were to burn in the void it is true, but oxygen would not fail them, for they would furnish that themselves like the lunar volcanoes, the deflagration of which has never been prevented by the want of atmosphere around the moon.
We shall use a large-grained powder," answered the major; "its deflagration is the most rapid.
