anyone know the smoke agent used in the

Enola gaye white smoke grenades

 

methyl anthraquinone ?

cinnamic acid - don't think so

terephthalic acid- don't think so

colophony- don't think so

 

others -

 

it produces a pale yellowish deposit on surrounding vegetation, but does not smell like colophony.

Hi,

 

Take a look at this

I think you're on the right path with the anthraquinone's but gawd only knows where you'd get this from

I'd be interested in what you learn as I enjoy creating smoke effects.

[dave]

that is quite an old paper, one which I had not seen, so thanks for that.

 

I am beginning to edge my bets on methyl anthraquinone but I could well be wrong.

 

it is marketed as a white smoke agent

Please understand that pyro compounding usually has PRICE as a major input.

Just done a few loose burn test with 1g kclo3 + 2g of the following fuels: dextrin, lactose, flour, cane/beet sugar, naphthalene, wood dust (only 1g of this due to density). lactose seemed to produce the most smoke followed by cane sugar then wood dust. Naphthalene as expected produced black smoke dextrin very little smoke, flour least of all but smelt the nicest.

 

A lot of smoke formulas contain ammonium chloride however i was a little reluctant to try this with chlorate as the oxidizer.

 

As Arthur said the cheapest will probably be your most likely formula

[dave]

yes, i am familiar with ammonium chloride in smoke compositions

 

just wondered what they were using

and the money is still on methyl anthraquinone (in china its probably quite cheap)

[fruitfulsteve]

Just done a quick search of methyl anthraquinone and got some conflicting information. It's on the hazardous chemical list and has anti cancer uses.Although I'm sure you done your research and know this already.

 

Are they definitely made in China ? There are a lot of this type of stuff still made in the UK. Spectrum somewhere up north is one of them !!

interesting.

 

I know of drain testers but didn't know they also used methyl anthraquinone

Looks like your source! I would love to see the results of this, you must share a vid.
