I read that atomized copper can be used to enhance the green colouring in a mixture and was wondering if its safe to do this with Barium Nitrate for a sparkle mix ...

My thinking is that as its an oxidiser and a metal powder its gunner make flash powder .. but then copper isn't as reactive as the metals we use to make flash so it should be fine .. but then there would be Al in the mixture as well ...

The full mix would be:

Potassium Nitrate - 53g
Sulphur - 18g
Charcoal - 11g
Aluminium (300 mesh) - 7g
Barium Nitrate - 7g
Atomized Copper - 7g
(mixture is a variation of D1 Glitter from PyroGuide wiki)

So what do people think?

** Fore not ** I'm new to pyrotechnics **

I was talking to one of my dad's friends (he does fireworks displays) a couple of days ago about adding colour to my fountains and he suggested using Strontium nitrate for a red colorant.

Having never heard of it I went to wiki and found it indeed is a red colorant and that it also produces Nitrogen dioxide which is a pretty poisonous gas.

Now my question is: If I use Strontium nitrate as a red colorant in my fountains will I need to worry about this Nitrogen dioxide?

And does anyone else use it for anything ... also your general input on colorants would be wonderful
