Black powder (he black powder) consists of three components – saltpeter, sulfur and coal. Proportions – 75% of potassium nitrate, 15% of coal, 10% of sulfur. And over time, they are very broad, I must say, indicators. For example, in medieval France, the proportions were 2/1/1. And nothing, guns somehow shot, the task was carried out. And only from 1650 at least some normal standard was established.
Types of gunpowder
Relatively speaking modern powder divided into smoky and smokeless. Black powder – A direct descendant of even the Chinese. Smokeless powder – it is a gas that has been burned out.
Both black powder and smokeless existed and exist in quite interesting varieties, depending mainly on the quality and quantity of coal. And this is a really interesting moment.
If standard firewood is annealed at a high temperature – about 350-450 degrees, then we get black coal. It crumbles easily, it burns without flame. And it will be quite small. Will come out of it black powder.
If the standard firewood is annealed at a temperature of 280 – 320 degrees, we get brown coal. Burned away, reddish on the surface of the sparks. It is 2 times more. Raw material for cocoa powder.
If the standard firewood is annealed at 150-180 degrees, we get chocolate coal. Almost doesn’t crumble It should be cool down without air access.
Brown and chocolate powder use more in artillery, because it is much more powerful. Seriously, this zadrotstvo with annealing is worth it.
There is a special sulfur free powder, It would be no sulfur at all. And that is typical for non-powdered powder just used chocolate charcoal. But it’s not.
And then there is white powder – it is just smokeless. This is a special perversion, which is now used only in rocket science. Composition – 75 percent potassium nitrate, 25 percent … sugar. The composition is stable, burns well, detonates as it should.
AND yellow powder. 55% saltpeter, 18% sulfur and 27% anhydrous potash or potassium carbonate. Stuck is more expensive than black powder, it is very much more promising, but it is very promising.
Method for determining the type of gunpowder and its quality
There is a pretty visual way. gunpowder checks, allowing to determine damage. We need a gunpowder, a small strip of paper and a stopwatch.
Take out the paper and fold it in half – it turns out such a “groove”. We measure two stripes. And we fall asleep between them 0.25 grams of gunpowder. We set on the stopwatch. When burned down. Yeah, I need a good reaction. And then – check the results.
- 0.5 sec – black powder
- 1.6 sec – black powder or smokeless powder, prone to detonation
- 1.8 – 2.2 seconds – good smokeless hunting powder
- 2.3 – 2.4 seconds – spoiled smokeless hunting powder
- 4 sec – pistol powder
- More than 7 sec – rifle powder
Oh yeah, we’re not sure how to make a black powder is banned. Roskomnadzor stands out, you know. It doesn’t matter. And it’s a way to go through a google translator. But no, faithful defenders inexorably guard the Motherland.
