In recent days I have treaty making based on nitrocellulose of blue llama, free (AP),

I have added copper oxide, copper sulfate, but no colour, if someone knows thank the contribution.

I've had success adding AP, Parlon and CuO.

 

This is starting off with a very hot double base, which burns cleanly. While AP and Parlon are not both needed for chlorine, I used them both because they form a balanced oxygen/fuel mix, and also lower the flame temperature enough to make the blue work better, since the CuCl which emits the blue light is not stable at higher flame temperatures.

 

Obviously you don't want too much carbon in the flame because it can cause incandescence and pollute the flame with yellow. Also you do not want too much oxygen, since that causes CuO to remain in the flame and produce red light.

What do you mean by "blue llama, free (AP) ?"

Would you clarify what you mean by "burns cleanly?" There are numerous DB NCs and fewer SB. Any preference or performance difference you've seen?

85 NC,

7 AP,

5 CuO

3 Parlon

I'll try tomorrow. I think it's a very good composition for the amount of nitroceulose I think it will not draw smoke.
Thank you. I have it like that
77 NC- 19 AP- 4 CuO

What I meant is Without ammonium perchlorate
