Cool cake!

That star is nice. Just wondering how you mix this one, since the comp is more or less a slow flash comp?

Grind the KNO3 and pass it through 100# screen, the sulphur AND dextrin are screened by 100# mesh too. Mix both aluminums, add the rest of the previously screened chemicals and gently screen 3 times through 30# screen. After this you can start rolling or pressing this comp.

In my experience Is not that similar to flash burst, the atomized aluminum make this burn slower and More sparkly rather than flash.

The flake alu makes pretty good flash. Mixing both alus first is probably a good idea, but I would still treat it with caution, avoiding friction and static electricity. Thanks!

The flake aluminum is actually bright flake aluminum (1500#), pretty messy as it gets airborne easy. This composition is not very sensitive, actually i had to give a layer of hot prime as it needed more temperature to ignite.

All cautions are welcome, how do you avoid static electricity btw?

I know, messy stuff, but as I said makes pretty good flash. I guess it's only sensitive as fluffy powder. When rolled and compacted it's another story.
Reg. static... wearing all cotton clothes helps and working when the weather is more humid.

You can also add more humidity to the work environment if you wet with plenty water all the floor of your Workspace.

You can also use one of those humidifiers that are sold at growshops  plus a termohygrometer. This will help you monitoring your working parameters, ensuring safe humidity levels in order to keep static risk at the lowest possible.

Excellent! Do you have any shots of the device and/or fusing?
