taiwanluthiers Posted July 20, 2012 Share Posted July 20, 2012 I made a similar comp but without the red gum... Strontium nitrate and a metal fuel and a chlorine donor makes a VERY bright flash, but if only Al is used its gotta be finely divided (not spherical). MgAl is a good choice... I will try later with dark Al because I found a cheaper source for those than MgAl. Link to comment Share on other sites More sharing options...
