Gilded Posted November 26, 2004 Share Posted November 26, 2004 "what chemicals can you add to give the smoke bomb coloured smoke" That's indeed a frequently asked and tricky question... I think someone said something about "artificial indigo"... I'm trying to look something up. Link to comment Share on other sites More sharing options...
Gilded Posted November 26, 2004 Share Posted November 26, 2004 OK, it appears that some of the commercial smoke bombs are made of approx. 20% potassium chlorate, 20% lactose and 60% unsoluble strong dye, for example paranitraniline, surrounded by a clay shell. I'm not quite sure if adding paranitraniline to KNO3-sugar mixture will impart a color on the smoke though. Link to comment Share on other sites More sharing options...

Gilded Posted November 26, 2004 Share Posted November 26, 2004 Btw, found a fun fact: The KNO3/sugar smoke bomb generates smoke about 600 times its own volume. So I hope the 45g lot doesn't go off in your house boris. Link to comment Share on other sites More sharing options...
boris_73 Posted November 26, 2004 Author Share Posted November 26, 2004 Damn thats not the worse part, because it can be kept safely i decided to make another batch and find an excuse to set it off probably down at my grandpa's end, he was the one who got me into things like this and helps me get my chemicals, anyway if it is true what you say total volume of 54000 will be coverd with smoke it best not go off in my bloody house Edit: today i am not at my brightest, days like these you know i am tired without me even telling you Edit 2: united nuclear has irritated me a bit because they said it was a small batch.... Small indeed ill set these two off in there office and we'll see what a small batch it is anyway if i am ever in danger i can light these and disapear Link to comment Share on other sites More sharing options...

Gilded Posted November 26, 2004 Share Posted November 26, 2004 "if i am ever in danger i can light these and disapear" That's ninjalicious. "What is the smoke actually made of?" You mean the smoke coming from a KNO3/sugar smoke bomb? Small carbon particles at least, carbon monoxide probably too, along with carbon dioxide. I'd imagine some water vapor being released too as the sugar decomposes. Link to comment Share on other sites More sharing options...

If you were to make this type of smoke bomb from the saltpetre sold at a garden supply store would any impurities affect the reaction much?

budullewraagh Posted November 26, 2004 Share Posted November 26, 2004 essentially the same products, although different amounts. oxidation of hydrocarbons yields water and carbon dioxide, and oxidation of glucose is similar except it takes a little less oxygen to react, as there is already oxygen in the glucose Link to comment Share on other sites More sharing options...
Gilded Posted November 26, 2004 Share Posted November 26, 2004 "If you were to make this type of smoke bomb from the saltpetre sold at a garden supply store would any impurities affect the reaction much?" I'm not sure if you guys use the same code for fertilizer, but here it's nitrogen-phosphor-potassium (for example 34-0-0 for NH4NO3). I'm quite sure that they're used worldwide though. Of course, the bag will probably say "saltpeter" but I recall that many different assortment saltpeters are used in fertilizing. It probably just says "potassium saltpeter", if it's a bag of KNO3. Also, I'd imagine the code for pure KNO3 is 14-0-44. Link to comment Share on other sites More sharing options...
boris_73 Posted November 26, 2004 Author Share Posted November 26, 2004 no the salt peter or also know as potassium nitrate sold at garden centers would not effect the reaction the potassium nitrate at garden stores is about 98-99% pure its fine for any reaction you want to do with it Link to comment Share on other sites More sharing options...
jdurg Posted November 27, 2004 Share Posted November 27, 2004 that's brilliant news this way i can keep it for as long as i want and be able to go to sleep with out fear im going to wake up with a house full of smoke and my parents looking over as if they had an intenton to kill me LOL. Well, don't worry. If the smoke bomb goes off there'll be too much smoke for your parents to see you anyway. tee-hee. Link to comment Share on other sites More sharing options...
[Tycho?] Posted November 28, 2004 Share Posted November 28, 2004 I tried making that stuff once at a friends house. We melted the saltpeter together with the sugar for a while, then lit it. It burned blue, and fast. It produced almost no smoke, so we either mixed it incorrectly or heated it for too long/ not long enough. Link to comment Share on other sites More sharing options...
budullewraagh Posted November 28, 2004 Share Posted November 28, 2004 i bet it burned lilac instead of blue:\ what were your proportions? how large was the flame in comparison with the reagents? btw jdurg, can you get nitrates where you live? i can't Link to comment Share on other sites More sharing options...

Just go to unitednuclear.com, or look for the Chemsavers store on E-Bay and you can easily get some nitrates. As for at the gardening store, I don't know. I know that getting battery acid is next to impossible where I am, and if you even ask for it they claim that they don't sell it and only use batteries that never need to be "refilled".

budullewraagh Posted November 28, 2004 Share Posted November 28, 2004 yeah, i have the same problem. we cant get any oxidizers where i live; nitrates, nitrites, chlorates, perchlorates, chlorites, permanganates, etc. they're even taking away simple common things like hydrochloric acid, which i rarely see anymore. theres almost no red phosphorus in match books...and i still can't find sulfuric acid either Link to comment Share on other sites More sharing options...

budullewraagh Posted November 28, 2004 Share Posted November 28, 2004 well, car batteries but they're SO poor, as the lead sulfate is left and theyre messy etc. i just dont like using batteries for sulfuric aside from that i have no source. i was thinking about using the lead chamber process, however, to make some sulfuric Link to comment Share on other sites More sharing options...
boris_73 Posted November 28, 2004 Author Share Posted November 28, 2004 Today i set of my smoke bombs in my back garden and to be honest in the open 45g is not that bad it produces a LOT of smoke in a couple of seconds and stays around for a few more but after a while it goes all though my neighbour did come out to see where all the smoke was coming from but she was'nt really that botherd and i asked her not to tell my parents which she wont do because we get along very well as neighbours:)))) and so i am deciding to make some more maybe this time about 1-2 pounds worth that will be a great smoke screen i have also concluded that 1. if you put the mixture in a cardboard tube with one end sealed the smoke last's twice as long all though it does'nt come off as fast and not as thick 2. if you put the mixture in a cardboard tube with no ends sealed it produces a nice thick screen of smoke and last for quite a while 3. if you dont put the mixture in any container and light it it burns very fast, a very thick dense smoke screen but it all goes in a couple of seconds so either option 2 or 3 are the better ones and if you have a large enough mixture e.g. 1-3 pounds option 3 would be the better one for a nice quick dense smoke screen, which should last quite a long time if you have large enough amounts Edit: also sparklers make excellent fuse's mine gave my about 1 minute to stand back so i decided to cut them in half and have a 30 second fuse and dont light a smoke bomb indoors the smoke would be even worse indoors because it has no where to go Link to comment Share on other sites More sharing options...
