oh please give me advice on sulfur with black powder

[Guest marker227]

I am going to make a smoke bomb.

 

It goes like this.

 

60/50 ratio.

 

Black powder with sulfur powder. I have both. I am going to use like 3 grams of powder and 4 grams of sulfur. In a cup or something. It said the powder will burn off the sulfur and make a white smoke. Is this true? I don't want it to explode. I am going to start it by inserting a hot red wire.

no it`s not altogether true, it`s make sulpher dioxide, and that`s colorless, it`s also very toxic!!!

 

why don`t you finely cut up some ping pong balls and add that to your BP instead, it`s a MUCH better result )

[Guest marker227]

I found that out to.. Thank you. Are there any ways I can use chemicals to make smoke like the smoke bombs you can buy from a army store?

[Cap'n Refsmmat]

I believe you can buy "Bottled smoke" at home improvement stores to test fire alarms, you could look at the ingredients in that.

[YT2095]

sure there is and better if you`re not to fussy about smell

 

using BP isn`t the way I`de go anyway, it burns too fast for a start, use an NC based powder either single or double based type, dissolve it in acetone and add sawdust, cast that into a cardboard tube then stick in a 10 sec visco fuse and let it dry in the sunshine for a couple of days.

the result will be a solid tube with a regular burn rate, not too fast and CLOUDS of smoke! as well as being mostly harmless (no more than sitting round a smokey campfire).

a 100g grain will fill a 20x20` room in seconds

NC based powder????

[YT2095]

NC = Nitro Cellulose, such as Pyrodex smokeless powder

[Lance]

Isn't KNO3 and sugar pretty safe/effective?

[YT2095]

it is, but the volume of smoke to weight is a bit cruddy

[MulderMan]

this is from memory but if youve seen the anarchists cookbook it shows a method involving boiling bleach. but ill get back to you on that one. is it cheaper to produce them or just buy them from a shop? cos i havent heard of Pyrodex

[YT2095]

Pyrodex is the powder used to reload bullets or muzel loader guns, no one usess black powder anymore because it`s corrosive and shities up the barrel and mechanisms, also kicks out loads of smoke

Pyrodex is a BP substitute. any modern bullet or shell will contain a NC based powder. Pyrodex is a brand name btw and although it contains no NC, it WILL work just as well

also boiling bleach will give you a crappy version of Sodium Chlorate, ya may as well just Buy the stuff!

[Phreak]

if you want to make smoke bombs the easy way is

 

KNO3 and icing sugar

60 : 40

but the trick to making it realy good is to melt the two together

 

low temp, in the end it should look like caramel then stick the fuse in before it hardens. I make a lot and form it in an Ice cube tray.

 

or 4oz rocket tubes.

be carfull with "candy rocket" mix! unless you`re REALLY experienced and take all safety precautions, it can and often does with learners, catch fire in the pan! even with experienced makers it happens on occasion. and it MUST be done outdoors for this reason!

uh oh. i guess i had a close call a few years ago before i had much chem knowledge. thank my lucky stars.

[r1dermon]

correct, never ever put the pan on a high setting...medium is the absolute limit, even if it takes a bit long, its better than losing your skin. also, i though something like red iron oxide could be added which would make the mixture solidify, correct me if im wrong, i just use the powder for model rockets.

r1dermon, google this: Rcandy

 

Adding Fe2O3 makes the grain burn faster.

[TWJian]

Sigh, anyone know how to make a smoke bomb or gunpowder with KClO3? I lack KNO3.Making flash powder seems to be highly dangerous.

[YT2095]

dissolve it in boiling water, then soak some news paper in it, or even bran flakes or corn flakes and let it dry.

 

it`ll kick out LOADS of smoke!

esp if you add a fine light spray of motor oil on it afterwards

The problem is that the area that I live in has a rather high humidity. Guess I just make a makeshift airing cupboard and dry it in it. Thanks for your suggestion.
