I gave this formula a go recently. It's a nice effect - bushy and energetic... not too much glittering happening, though. The video shows a few good flashes at the end, otherwise indistinguishable from the main column of sparks. I'm getting the feeling that my Aluminium of roughly 250mesh is not going to cut it as fas as glitter is concerned.I have noted this formula from Lancaster:
BP: 76
Strontium Carbonate: 10
Antimony Trisulphide: 8
Atomized Aluminium 350 mesh: 6
I can't seem to find "bright" aluminium anywhere, so I'm trying to find some glitter formula which uses Aluminium of a larger particle size. UN lists their coarse granular Al as being used in "some" glitter formulas - has anyone heard of any glitter formula which use Aluminium in the <325mesh range?... I'm not having any luck......
