Out of which materials are smokeless roomfontains

[Polumna]

hi dudes,

 

I recently bought some smokeless fontains, they are for indoor using, now the question is:

 

out of which chemicals are they made???

 

the powder which comes out of them is yellowish, and they burn with silver sparks!!!!

The ones that we've got here in denmark is made out of nitrocellulose and titanium, because the waste product from the reaction is non-toxic. The powder is white and a little grey, so I have no idea what the american fountains contain.

He's from germany.

 

Chances are it is just NC. Perhaps Ammonium Perchlorate. There are some smokeless flashes based with zirconium hydride and barium oxide/nitrate. Could be something like that as well.

Well since this is here I got a question,

 

 

I have access to bars of titanium for pool and I was wondering if that would work in fountains and how could I grind it into powder if it would work????

I believe they also use Misch metal in 'cold' fountains.

 

The yellow tinge may be due to the NC getting a little old.

Yes, the Ti bars will work, it's just grinding that is is the problem. Ti is very hard and will tear up ordinary steel tools. I believe silicon carbide tools are required.

The indoor fountain I’ve used are sulphur based I think with Ti for sparks. The sulphur sinks the place out which can be a problem

[Mumbles]

I doubt they were sulfur based if they were meant for indoor use. Or they could have been meant for outdoor use. Pumping off noxious chemicals and a bunch of smoke is not the primary objective of indoor pyro. It may have just been an old batch of NC. It can give off some NOx.

The bloke I work with said they are and they sure smell like it, he was saying there not as bad as the ones he use to get once the building he was doing it in had to be evacuated it got that bad.
