Hi there,
a question this time.
I know there are many companies in UK that sell colored sparklers. Would someone please describe them a little bit? What is interesting to me, is how good is the color (I know there are red, green and blue sparklers)?

Thank you

The colour is okay, but not good. Coloured sparklers are nothing special. The colour only appears in the small area of flame that is visible on the sparkler itself as it burns, the sparks themselves are not coloured. The fumes can be a bit much (well for me anyway). Coloured sparklers suffer from the phenomenon that most coloured flames do, they are better viewed at a distance that at close proximity.

I've never seen any commercial blue sparklers, but I've seen good red ones - not a deep, Strontium Nitrate red, but reasonably vivid. I can remember the green ones being a little pale and washed out, very similar to theatrical green flash.

Thanks. I'm working with the thing. Sparks of Fe give so high yellow spectrum that it hides almost all the color. That's why it is interesting to know, how good are the other ones.

There is a very large post with many forumlas - good place to start anyway. Search the forum.
