muxolini Posted October 17, 2017 Posted October 17, 2017 Hello people I bought professional Red smoke dye and mix KCLO3, SUGAR AND Magnesium Carbonate. I have a problem guyswhen ignition coming to the fire sometimes to the fire. Sometimes black smoke. I'm doing the wrong thing ? Ty video-1508240875.mp4
AllisterF Posted October 17, 2017 Posted October 17, 2017 (edited) You might want to post up your mix ratios (as well as the dye you used) and maybe someone with experience using that dye and mix will steer you to a better ratio to cool down and slow down the burn... The black smoke and big flame is because it's burning too fast and hot... Edited October 17, 2017 by AllisterF 1
muxolini Posted October 18, 2017 Author Posted October 18, 2017 Hello guys I managed to get it red smoke. Does anyone know how to get it dense smokeKCLO3,DYE,MAGNESIUM CARBONATE,sodium carbonate,LACTOSE
AllisterF Posted October 19, 2017 Posted October 19, 2017 Read my post above, it's still pertinent to your new question... 1
Mumbles Posted October 19, 2017 Posted October 19, 2017 Use a better formula, use a better dye, or use better techniques. 1
greenlight Posted October 19, 2017 Posted October 19, 2017 (edited) Post your formula no one can help find the problem if we dont know the ratios your using. Edited October 19, 2017 by greenlight 1
muxolini Posted October 19, 2017 Author Posted October 19, 2017 (edited) I have no scales but me watching youtube video I do not know what's wrong. https://www.amateurpyro.com/forums/gallery/image/4197-hlorat-i-karbonat/ Edited October 19, 2017 by muxolini
MrB Posted October 19, 2017 Posted October 19, 2017 I have no scales but me watching youtube video I do not know what's wrong. I'm going to suggest that the problem is in the first line. 2
greenlight Posted October 19, 2017 Posted October 19, 2017 Haha I agree, dude you need to use scales when weighing out any pyrotechnic compositions. The coloured smoke formulation is quite dependant on burn temperature to work properly. The dye needs to be vaporized but nor burnt. Increasing the oxidizer or fuel content too much accidentally i.e. innaccurate weighing, can mean the difference between red smoke and dark brown/black smoke. I have the same brand dye as you and it performs fine.That dye looks orange in the container as well not red for some reason like mine. Also, the composition uses lactose whenever listed, not table sugar. 1
muxolini Posted October 19, 2017 Author Posted October 19, 2017 Pyromaniac Can you write me exact amount of grams that you use. Maybe you can also record your smoke I would be thankful
Arthur Posted October 19, 2017 Posted October 19, 2017 Accurate weighing is important! you need some scales and the ability to measure to 1% or better. 1

greenlight Posted October 20, 2017 Posted October 20, 2017 I will find my formula when I get home and post it up.It is very similar to this one written in the description of the video: https://www.google.com.au/url?sa=t&source=web&rct=j&url=https://m.youtube.com/watch%3Fv%3DsJj1YKeZLGM&ved=0ahUKEwj0spq0rv_WAhWKXLwKHTCuAWMQwqsBCDUwCA&usg=AOvVaw10VOoaWPZYW3wrWnRyxwsV 1
Arthur Posted October 20, 2017 Posted October 20, 2017 A typical coloured smoke will contain 25% lactose, 25% pot chlorate and 50% of a chosen sublimeable dye. ALSO the housing is important. Likely you will have to try several casings. However there are other formulae, inerts and inhibitors may be added to slow the flame reaction. 1
AllisterF Posted October 21, 2017 Posted October 21, 2017 ALSO the housing is important. Likely you will have to try several casings. I don't have much experience with smoke bombs, but from what I have seen is that housings that have for the lack of a better word a 'snuff' or 'containment' chamber that prevents the burn from easily getting outside oxygen and concentrates the smoke before exit seem to produce thicker smoke then open end tubes or what not... 1
Arthur Posted October 21, 2017 Posted October 21, 2017 The surface of the burn needs to only burn with the chemicals in there, not with atmospheric oxygen. This way you control the degree of burn and get smoke not burned dye. 1

However there are other formulae, inerts and inhibitors may be added to slow the flame reaction.Whoops I forgot to state about the casing, the most simple ones I used to make were wrapped in one layer of foil and many wraps of tape. Otherwise I used to press it into a tube the main factor being oxygen can't get in. You can take this other red formula I have and tweak it to your own satisfaction: KClO3: 29.5Lactose: 18.0Red dye: 47.5MgCO3: 5.0 Heat can be controlled by adjusting the oxidizer/fuel ratio but avoid excess oxidizer. The greater the amount of dye the slower the burn rate as well.The Magnesium carbonate acts as a coolant (and maybe gas neutralizer?) Absorbing heat as it decomposes. Adding more MgCO3 can also help slow down a mixture that burns too rapidly.

AustralianPyromaniac Posted October 21, 2017 Posted October 21, 2017 To su procenti, ali možete ga tretirati kao gramove i dobiti 100g zajedno. Regards, AP
AllisterF Posted October 21, 2017 Posted October 21, 2017 thank you greenlight I'll try that. Is that in grams ty It's a percentage ratio, use any weight based measurement you desire...

Arthur Posted October 22, 2017 Posted October 22, 2017 The down side of smoke is how much dye you use for a few seconds of effect. 100g of smoke should last less than a minute as a smoke but 50g of dye would dye all of the clothes you own! A carefully made BP based firework leaves no trace when it is fired, any kind of smoke leaves proof of it's firing for months.

I just need to work on for density smoke
