  • hey Dornier335A I like what you said and you know your stuff about deflageration versus detonation. I'm a chemist check out my vids. Subscribe to me I will to you. talk soon Peace be carefull

  • You got a lovely reddish/orange glow with this. I wonder if you could improve that by mixing in some strontium or lithium salts in?

  • @RadioTrefoil

    That would probably slow it down a bit. And I don't think it would do so much difference. 

  • Would Armstrong's mixture detonate ANFO? Could it be used to make percussion caps and reloading primers? I and a bunch of good ole boys need to know in case someone gets re-elected.

  • @bmcgraw3840

    No, AM can not detonate ANFO, you need a booster to do that. You can make detonators with Armstrong's mixture but it's really stupid because it's so sensitive.

  • mate that would be better in day light

  • Hello friend, I tried the same proportion but instead of using magnesium magnalium I used to 50/50 and has not worked for anything, not even turned on. Could you advise? What magnalium mixture could be done with a similar effect?

  • @CostraBrava

    How fine is your MgAl?

    KClO4 / MgAl is a very good flash powder.

  • @Dornier335A I bought magnalium than 350 mesh, and I ground in ball mill with steel balls for 10 hours. This combination of KClO4 / MgAl that ratios are?

    Thanks for all friend

  • @CostraBrava

    10 hours is not enough... You should ball mill it for a week or grind it with my steel plate method.

    NaNO3 or KNO3 / MgAl are very fast flash powders too. I think the ratios are about

    60 / 40 oxidiser to MgAl.

  • @Dornier335A thanks friend, I tried a mixture of NaNO3 + magnalium the proportion 60/40 and I did not catch fire. Could it be that the NaNO3 had too much humidity? Balls are formed continuously and is difficult to sift Thanks for all

  • i sell Potassium perchlorate, magnesium powder, aluminium powder, german black and send into UK

  • Did you coat the Mg? Based on the rate of deflagration, i'd say you had very dry NaNO3. How was it milled and mixed without taking in much water? Nice composition! I wonder if it can be pressed into a motor casing.. Ever try it?

  • @ikinner

    No, I did not coat the Mg.

    My NaNO3 stays dry during the winter and spring because the air has relatively low humidity.

    You mean to use it as a rocket propellant? It can definitely be pressed without ignition but I have only tested compositions with more charcoal than magnesium as rocket propellant.

  • Normally I don't favorite flash powder videos, but this is a show of a skilled pyrotechnician at work instead of an idiot mixing two things together he knows nothing about.

  • Well my first thought was that the 'detonation' is merely the excess Mg being volatilized and reacting with the oxygen in the air.

  • Ok , why would this composition detonate?

    It has a fairly large negative oxygen balance of around -30%.

    In comparison , 70/30 Kperc/Al flash has a oxygen balance of +- 5.5%.

  • @anjin33

    The magesium reacts with the nitrogen produced by the reaction.

    Instead of 5 Mg + 2 NaNO3 --> 5 MgO + N2 + Na2O

    is the reaction like this: 8 Mg + 2 NaNO3 --> 5 MgO + Mg3N2 + Na2O.

    And if it is more magnesium it will react with the oxygen in the air like a thermobaric bomb.

    Now i don't use charcoal at all because the flash powder is more powerful without it.

  • lol tell the composition and then say don't try this at home

  • I'm going to have to try this.

    Very nice man.

  • this is actually a very dangerous way of doing it. as you mill any reactive metal, whether using your method of the more traditional ball mill and the metal becomes this fine it is actually so fine that it has airiated and trapped oxygen between the particles. the Mg becomes a flash in its own right at this point and im sure you wouldn't grind flash powder.

  • that lead to a thread of a forum i post on, when the guy opened his ball mill, the friction from doing so was enough to ignite the magnesium and he ended up with first degree burns over a large part of his body. you are using steel against still, the above example was rubber against plastic. steel against steel sparks very easily, it would only take the slightest spark at the wrong time and your mill would become a bomb. this all being said, it is a very impressive flash powder.

  • @ccharvey1902

    I've heard of that accident before. But I use a completely different milling method that has no risk of igniting the magnesium powder. I think you have to watch my video about how i make my magnesium powder: How I make super fine powdered magnesium and aluminium powder (1 micron)

  • @Dornier335A

    I am an HE pyro, but these are extremely brisant powders you've made. Bravo.

    How sensitive is THIS particular mix to friction/impact/ spark?

    You have made some truly excellent videos in terms of sensitivity, but in the future if you do, please include pizoelectric lighters. They cost about $3...cheap shit, but simulates that static spark.

    Static electricity is the biggest bitch with FP....any kind of FP.

  • @dawson01913

    I have tested my flash powder with a piezoelectric thing from a lighter. It was impossible to light it even if the spark went right trough the pile. I needed to use a 3700 μF capacitor loaded to almost 40 V to ignite the powder with a spark.

    In the spark tests I used flash powder with slightly bigger particle size, and without charcoal.

  • @Dornier335A

    Do you believe charcoal significantly elevates the sensitivity of this mg/nano3/charcoal powder? Charcoal isn't the most sensitive ingredient, from my understanding or experience.

    I may try to make this powder in very small batches and fully test out its properties. Maybe it could substitute primaries for some people who play with HE.

  • @dawson01913

    Well, I used the charcoal because the powder was easier to light than without charcoal.

    And more gasses are produced in the reaction with charcoal.

    Actually I don't think this flash powder can initiate HE, ferrocerium flash powders will probably work better. But it's worth trying.

  • @MrKennybomb1 First I filed a piece of magnesium to get 100 micron (140 mesh) powder with flake shape. Then I milled it between a steel plate and a steel bar. It's hard to get finer powder than 10 micron (1250 mesh) but I succeded.

    I make aluminium powder the same way.

  • @Dornier335A this is actually a very dangerous way of doing it. as you mill any reactive metal, whether using your method of the more traditional ball mill and the metal becomes this fine it is actually so fine that it has airiated and trapped oxygen between the particles. the Mg becomes a flash in its own right at this point and im sure you wouldn't grind flash powder.

  • Ka-Boom!

    Would have been funny to be there and see it with your own eyes.

    Thumbs up

  • Holy shit that was awesome! What kind of Mg was it? Mesh? And what kind of charcoal was it? I guess a soft-wood?

  • @pyr0ph1L

    The magnesium was homamade 5 micron or 2500 mech powder.

    I don't know what kind of charcoal it was, it was a charcoal briquette i took from the grill.
