Flaming

[dar303]

Wow, very nice! A guess it's bit hard to get the permits to use this at a club or show without a lot of hassle.

You need to have a "pyro license" (or whatever the license is called for the pyrotechnics people), to use these in public places. I guess if you lived out in a remote area it ould be OK just to fire these off, but if you decide to use them publicly (Depending where you live), its gonna cost you abit in liability fee's

Pretty cool otherwise. I can imagine how the colours were changed.

we found the patent for the sigman systems colored flame pots, they use compressed air and propane and a pressure boosting ram to get 2000-4500 psi. They do sell the color flame oil in small amounts and I want to know how they get that saturated blue with no sodium contaimination and no parlon additives. (i'm not into home pyro, but I like purdy colors)

There are other chlorine donors than parlon. I'm guessing they use DCM (liquid, bp 40°C). Not very environmentally friendly. It is actually banned for all but research use in Sweden.

It's interesting that they can get such a big flame without sooting using propane. Soot colors the flame yellow and you need a very good fuel/air mixture to not get it.

but somehow this makes me think its NOT dcm:

when you can get them at local candle shops,here in the states, its benign.


OK, a recent patent search shows that what they call a oil candle is ethylene glycol and a alcohol, plus the salt, plus some HCL. A few other patents claim a unknown catalyst coated on the wick in addition to the salts for 'eliminating the yellow color"

no but DMX is an option...

DMX has no error checking, so a power glitch can make your flame projector fire. DON'T use DMX for flame effects unless you really know what you're doing.
