    Nitrate levels in the lab cotton were too low, as there was a great deal of residue left behind. Fully "nitrated" guncotton leaves almost no residue and a slight bit of moisture. It practically vaporizes.

      @@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. I'm not sure how the concentration would change things, I'm fairly sure it's the temperature and soaking time that are the most critical factors though, as I've seen demonstrations of household chemical sourced guncotton which deflagrated with almost zero residue. A film of ash and condensation being all that was left. Hers was pretty inefficient and left a lot of dirty solid residue. C- could do better!

    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%.

      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.

    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.

    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.
