@@MrRedeyedJedi She should have left it for a fair bit longer. If you're doing it with low grade acids it wants to soak and nitrate for 24 hours.

Gun cotton has way more brisance than black powder which accounts for it's ability to split the rock into many pieces rather than venting much of it's energy shooting up through the drill hole. In spite of it's limitations black powder remained in use for many years after the invention of guncotton and even dynamite, mainly to split large logs and to dislodge tree stumps.
FYI that is NOT Guncotton. At best she made Pyroxylin (Nitrogen content of between 8.0 - 12.3%). Way too much ash left over to be anything remotely close to guncotton, which by definition has a nitrogen content of at least 13.35%.
So, if it didn't fully nitrate then, it's not guncotton. Pyroxylin is nitrocellulose with less the fully nitrated cotton. Gun cotton is nitrocellulose with fully nitrated cotton.
@@wessonsmithjr.6257 What was it about her method that resulted only in a partial nitration? Did the colder temperature slow down the reaction of the concentrated nitric acid? Would it have been a different story had she simply allowed the cotton wool to soak for longer?
@@Mrjmaxted0291 Longer nitration. At least twice as long as she did. On a side note, I haven't messed with gun cotton ever since I started messing with Tetrazoles, Erythritol Tetranitrate, Nickel Hydrazine Nitrate, etc. Wayyyy more fun to play with.:)
Nitrocellulose cant be compared to black powder as nitrocellulose is considered as high explosive and can go to deflagration to detonation in relevant conditions, while black powder is still low explosive , it only deflagrates no matter what.
@@jdhudson2211in fact nitrocellulose was created in paris by henri braconnot. They probably had ice... not that it is really that necesary for making nitrocellulose though.
ice really isnt required you could use water in a bigger tub or flow cool water though a tub the water/ice combo just is easier to cool in small containment the reason to cool is to slow down the reaction think of it as brakes on a truck exothermic reactions can become violent with boiling frothing churning action think mentos diet coke but with hot boiling acid spewing out like a volcano makes a potentially harmful mess slowing down the reaction alows the chemist to brake/control the speed
Fuse, blasting cap, or just a battery and steel wool. Anything that will make a spark. You can also impact it with a hammer but I just don’t think I would want to be that close to it.
Ooo I know this comment is two years old, but I just really want an excuse to share my firearm related nerdery Yes, you could compress nitro cellulose to make it more powerful! that's actually one of its biggest advantages over black powder. when you compress black powder it'll eventually get to a point where it wont really produce any more gas pressure or kinetic energy, but you could theoretically compress nitrocellulose to the point where trying to actually use it would be, for all intents and purposes, suicide. And to answer your second question, compressing nitro cellulose or putting it under high pressure isnt actually all that dangerous, nitro cellulose isnt impact sensitive, it needs a certain level of heat and energy, that's why metallic cartridges need primers to function
@@cheskotokarev Guncotton can be impact or shock sensitive if the nitrification level is high enough. This was an issue when highly nitrifed guncotton was used as bursting charge in naval shells as the gun cotton will often detonate before the shell penetrated through the armour of targeted ships. They got around this issue by wetting the guncotton with water to reduce its sensitivity.
@@kovona Oh, I didn't know about that! My knowledge is pretty limited to small arms, and at that scale I believe it would be incredibly difficult to put enough kinetic energy into the powder itself to make it go off, but that is really quite interesting regardless!
I've watched so many videos and made so many batches of gun-cotton the fact that there was so much carbon left over that chemists does not know how to make gun cotton to save her life she needs to go back to school
Yeah, the cotton didn't turn that yellowish color that fully nitrated guncotton should have. Plus did you notice how she completely avoided answering the question of what would happen if the temperature of the reaction went above 17 degrees? Shit chemistry!
Sure, nitrocelulose is actually modern gunpowder. There are some additives to control burn, but you can try. Just be super carefull, it may burn much faster and blow up yout gun.
"Wet nitrocellulose is very volatile " No it isn't. Have you ever tried to ignite wetted nitrocellulose? You can't. It's how nitrocellulose is transported in the US for safety. They wet it.
They skiped the next step where they plasticize it with acetone and press thru a spaghetti like press that use 3 tons to extrude it to the shape u see smokeless powder in today
Gun powder, charcoal-sulfer-potasium nitrate, and gun cotton are not explosives but are, in fact, propellants. Confined they to exhibit explosive results due to confining the expanding gasses. Real explosives propagate at much higher speeds where touching them off even unconfined explode. One would not want to do to an explosive what was shown in this video. The result would be an explosion not just rapid burning of black powder or nitrated cotton.
I assume you mean a cartridge? If so, yes. Single base smokeless powders are compromised of nitrocellulose, double base powder use nitrocellulose and nitroglycerin, and triple base powders use nitrocellulose/ nitroglycerin/ and nitroguanadine. Now for use as a propellant, there are different chemicals used to control burn rate, act as stabilizers, etc. But nitrocellulose is the primary ingredient.
Actually it doesn't detonate. The explosion is not a detonation, but rather a deflagration. Look it up on wikipedia for more info. Basically only high explosives (C4, etc...) detonate, since the shock-wave is faster than the speed of sound in the material. Gunpowder deflagrates, since the shock-wave moves slower than the speed of sound in the gas produced.
@@drgrlitz look it up. To make the cotton, potassium nitrate is combined with sulphuric to create nitric acid. Or if obtainable, nitric acid it's self is used.
The difference is the brissance. That's what makes it so effective for mining operations versus black powder charges. It's probably the only high explosive that would look totally innocuous on a ladies dressing table lol. I can't believe they let him stand that close, with no shield though! That's pretty damn close, and pretty damn stupid! Especially when you know full well that there's the potential for supersonic shards of rock to be filling the air. Even with that relatively low quality, partially nitrogenated guncotton, it's still going to detonate. If I was their insurance company I'd be having blue fits over that footage lol.
You’re on the right track. If you experiment with that train of thought long enough, you end up with Cordite. Which is the same explosive that Britain’s used in its guns in WW1 and WW2
Vaseline was used in the manufacture of Cordite which was used as a propellant for various cartridges and guns. The vaseline byproducts would coat the bore of the rifle or cannon to prevent erosion and rust since Cordite produced very high temperatures.
Gunpowder is black powder. They just are two names for the same thing. "Gunpowder" is the original, "black powder" was coined after the smokeless powder was created.
Maybe someone else actually packed the 5g of gun cotton into the hole, because this definitely doesn’t seem to 5 grams. it was more like quarter of a gram to half a gram
