Hey, 

I'm new to this forum, and I'm also not really an amateur fireworks maker, but I do use fireworks and I have a question that I'm out of my depth on. 

Fire spinners quite often add Ferro-Titanium to their wicks, (after fuelling them with kerosene) to create a sparkler like effect as the wick burns, and the metal powder flies off and burns also. It's a pretty awesome way to make people happier to see you spinning fire, and the effect lasts quite well throughout the burn, (which can be 2m-10 minutes long, depending on the size of the wick.)

But that's not my question. I was thinking about how to achieve a coloured version of this sparkler effect. Coloured flame is not what I want, but a coloured sparkle with the silver of the ferro-titanium. Obviously I thought about using copper powder, but that doesn't work so good, or at all. I'm not sure that the kerosene burns hot enough to make it react. Kero burns at like under 250 celcius as far as I know. Which is not far, cos I haven't stuck a thermocouple in there.... 

I wondered if I needed a different chemical or a chlorine donor and a metal carbonate or some thing, and use the paraffin as the fuel? But I also have to be careful of the fumes produced and any falling sparks, cos I'll be pretty close to the action. So I don't particularly want to use any really toxic chemicals, or any thermite because I am not too keen on it falling on my skin. 

Also, I was wondering it there was any sparkler recipes that would do the job, or any alternative chemicals for ferro titanium. Or if I should make tiny sub 1mm stars and add them to the wicks, assuming there don't all burn immediately... 

I hope this provides some interest for you guys...
