murderskill Posted May 13, 2006 Share Posted May 13, 2006 Idk. I'm sticking with kclo4/al Link to comment Share on other sites More sharing options...
artificier Posted May 13, 2006 Share Posted May 13, 2006 i found the loudest flash powder in skylighter.comthe best flash powder its 50/50 of a mixture of standard flash powder 70/30 with bulleye smokeless powder ! Link to comment Share on other sites More sharing options...
Mumbles Posted May 13, 2006 Share Posted May 13, 2006 Thats not a flash powder though. That is flash powder and smokless powder. I hardly doubt that is the loudest by the way. Link to comment Share on other sites More sharing options...
Canadian_Pyro Posted May 14, 2006 Share Posted May 14, 2006 This is slightly off topic, but does there exist a KClO3/Al flash? I have been attempting to find a comp that doesn't utilize sulfur, the best alternative so far being sugar. It is not comparable to KClO4/Al. Does anyone have any ideas? Sure. When you mix a powerful low temp oxidizer with a metallic fuel, what do you think is produced? Flash Powder. You must calculate the proper proportions of ingrediants, obviously. Start by working out the reaction. KClO3 + 2Al -> Al2O3 + KCl A very simple reaction, now take the atomic weights, K = 39Cl = 35O = 16Al = 27 Substitute in the weights, and calculate. [39+35+3(16)] + [2(27)]122 + 54176 Then divide the weight of one of the reactants by the total weight, and multiply by 100. 122/176x10069 A 70/30 mix would be optimal.

Canadian_Pyro Posted May 14, 2006 Share Posted May 14, 2006 KClO3 is a more powerful oxidizer than KClO4 because its decomposition i more exothermic, this also makes it more sensitive to ignition, your flash should ignite more easily than it would if you were using KClO4 as the oxidizer. Perhaps it is your aluminum. Are you using spherical or granular or flake? What mesh size? Link to comment Share on other sites More sharing options...
Swany Posted May 14, 2006 Share Posted May 14, 2006 I mixed a 70:30 with german dark Al and pure KClO3 and it worked beautifully. I couldn't really tell a difference between it and perchlorate based flash, but it worked. Link to comment Share on other sites More sharing options...
Canadian_Pyro Posted May 14, 2006 Share Posted May 14, 2006 I have already looked into all that. The problem is not the chemicals, it is the composition itself. The KClO3 decomposes before the Al has a chance to actually react...... basically meaning I get KCl/Al instead of the wanted Al2O3 + heat. Sulfur would be used to reduce ignition temperature..... but there is that small side effect of being unstable. Sucrose is the best alternative I have found so far.... but it's still rather poor compared to KClO4/KMnO4 flash. I can get the KClO4 without a problem.... just wondering whether people actually have used KClO3 based flashs.... So you've tested the solubility of the white crystalline compound left over in a certain quantity of water to confirm that it is KCl? 34.4g of KCl dissolves in 100ml of water. 1 Link to comment Share on other sites More sharing options...
Canadian_Pyro Posted May 14, 2006 Share Posted May 14, 2006 Stop blaming the chems. If it will not ignite, there is something wrong with the process you used to produce it. Perhaps your KClO3 is not finely powdered enough, or the mixing is not adequate. It should ignite very easily, as it has each time I as well as many others have used it.

[w00t] Posted May 14, 2006 Share Posted May 14, 2006 Do you have to use either; Parlon/PVC or RedGum combined with e.g Strontion Carbonate, Copper Oxide to create coloured Fire/Sparks? Link to comment Share on other sites More sharing options...
Pretty green flame Posted May 14, 2006 Share Posted May 14, 2006 I'd rather not blame anything and just use KClO4. What is the best colored flash powder? I am still waiting for a few packages (due quite soon), so I can't experiment yet .Excelent colored flash powders can be made by mixing a color producing nitrate (Sr or Ba) and magnesium in the ratio of 1:1. Ba(NO3)2 and Mg will produce a flash that flashes with a blinding green light. Excelent. Haven't tried Sr yer so i can't really say how it will perform.

RUUUUUN Posted May 14, 2006 Share Posted May 14, 2006 I have found Ba(NO3)2/Mg to have a white flame envelope with a green tinge around the edges, but if you are a distance off it is a nice green color. Sr(NO3)2/Mg gives a nice pink/red flame envelope and an incredibly bright flash. Without the Cl donors those rich colors jsut aren't there, rats.

Rooster Posted May 14, 2006 Share Posted May 14, 2006 To get a nicely colored flame from flashpowders, the maltese often add a chlorine donor, mostly PVC. Parlon will not work as well, because it is a flame retardant. The reaction is so fast you need something that burns together with the other ingredients when ignited. This is especially true to get a good green from barium nitrate/magnesium flash. 1 Link to comment Share on other sites More sharing options...
[w00t] Posted May 17, 2006 Share Posted May 17, 2006 I made a rather bright flash, with atomized 400mesh Al + home made potassium chlorate and a very small pinch of red iron oxide. here is video i just took http://media.putfile.com/Bright-Flashpowder amount ~ 0.2g Link to comment Share on other sites More sharing options...
Canadian_Pyro Posted May 17, 2006 Share Posted May 17, 2006 Very bright, I am seeing spots after watching that vid. Link to comment Share on other sites More sharing options...
ltf Posted May 17, 2006 Share Posted May 17, 2006 The best colored flash i think is Ba(NO3)2/Sr(NO3)2/PVC in the ratios of 12/12/1, be carefull these flashes are extremly violent.The cheapest and loudest flash is KMnO4/Mg its like the barium/Mg/PVC explodes in the open.Try these flash powders and be carefull By the way KKnO4/Mg flash in a salute makes a blast like a tank.

FrKoNaLeaSh1010 Posted May 17, 2006 Share Posted May 17, 2006 Anyone have any personal experience with the comparison of KClO4/Al and KClO4/Al/S. I know the Shimizu flash comp of 64/23/13 is said to be the loudest of the KClO4/Al/S mixes but how does it compare to just KClO4/Al 70/30? I ask this only because I am running low on perc and Al and wish to have more bang for my buck basically. Link to comment Share on other sites More sharing options...

shadopyro Posted May 19, 2006 Share Posted May 19, 2006 Wow havent come back to this topic in ages... But anyway, i discovered another flash powder by accident, unorthadox i must say...mix 50:50, 50%(70:30 kclo4:Al) with 50% (thermite 3:1 Fe2O3: Al-where the Al is very fine Al i used 10 micron). I was pretty bored, so i lit it with a thin blackmatch thinking that this would just fizzle and send sparks everywhere, but suddenly "thummmph!". i was dazzled and blinded for about 10mins!I havent managed to try it in a salute yet in comparison to normal 70 30 flash, but seems pretty fast burning and lights as easily as my 70 30 flash powder. Anyone wanna try this mix in a salute? i could post this in the compositions section if needed. Oh yeah and if you really wanna have all powerful flash powders with higher risks then i might be a more worthy thought of learning a biut more and going into high explosives. When i tried the KClO4 Al S one a while ago, all it did was sizzle and crackle loudly, while filling the air with the stench of pure SO2 gas, dont think i'll be trying that again untill i get some German dark Al.

lacrima97 Posted June 12, 2006 Share Posted June 12, 2006 Guys, I hate to break the news, but the best flash is. PURPLE FLASHKClO4.......37Sr(NO3)2....11Mg (-400)...37CuO.........11PVC.........04 Purple is my favorite color. Source: -Degn Link to comment Share on other sites More sharing options...
FrKoNaLeaSh1010 Posted June 12, 2006 Share Posted June 12, 2006 You think you could post some info about that purple flash like how good the color is and burn rate. I was planning on trying that this week. Link to comment Share on other sites More sharing options...
lacrima97 Posted June 12, 2006 Share Posted June 12, 2006 I would post something about it, but actually, I have never made flash powder. It is my current fav though, because it is purple, and has chems that I will have access to within the month. Link to comment Share on other sites More sharing options...
lacrima97 Posted July 2, 2006 Share Posted July 2, 2006 I just tried the purple flash powder with 500mesh magnesium. It completely and utterly kicked my ass. Sadly, the flash wasnt purple though. More of a...light colored white. I don't currently have any dark Al, so I am wondering how this compares to the standard 70:30 flash mix. This stuff was definately awesome on the loud scale. Echoed for around 4-5 seconds. It was 10g btw. This is the first flash powder I have ever made and (i'm not sure if this is allowed or not) compared side by side to say 10g of HExplosives, the HE doesn't compare. I have never felt a "kick, shockwave, whatever" like this from 10g of an HE. Flash is just awesome. Link to comment Share on other sites More sharing options...
optimus Posted July 3, 2006 Share Posted July 3, 2006 My favourite flash has got to be German dark Magnalium/Kcl04. I'm not overly keen on bangers/salutes but the sound of a few grammes burning in the open is amazing For purple salutes, I think a modification of the Degn violet flash might give a better colour.

Mumbles Posted July 5, 2006 Share Posted July 5, 2006 You might need to be farther away for the purple light. I've use a green flash of 50:50 Ba(NO3)2:Mg. Closer than 100 feet or so it looks very white with some green tinges. When it is several hundred feet away(in the air) it is much greener.

weknowpyro Posted July 5, 2006 Author Share Posted July 5, 2006 Just asking around but has anyone ever experimented with silver nitrate water ignited flash before? There would not be many uses for it but it would be intrested to see i expect. Link to comment Share on other sites More sharing options...
