I have a question for those experienced at making fireworks. At 1:10 in this video, you will see the fireworks adding silver powder to the shell. Is this a flash composition?

Great video by the way

I am not experienced at making fireworks butt i do know lots of southern european shell builders use a flash booster in there small(6") spherical shells.

It's a flash booster indeed, to increase the break strength/power. Gives the stars that extra push.
If you put the flash in a small bag, and put this in the center of the break, then you have a so called flash bag.

You actually want the slow flash to mix with your rice hulls(burst charge). -325 mesh Al and Kno3 is usually used, and it is more commonly used/needed in smaller shells. Also the smaller the shell is the more booster one can use. Awesome vid BTW!

Great video. thanks dave

Yes that is most likely slow flash like pyromaniac stated that amount of reg flash would most likely cause to hard of a break

Awesome vid indeed I too use the slow flash in my shells, kno3 and dark aluminum and that works well.
