Will this mess my stuff up?

@kalkbayrock Your blender / coffee grinder? Yes, it won't destroy it but the blades will lose sharpness.. So I recommend buying an additional blender with some spare blades exclusively for pyrotechnics. Each 200g of aluminium I have to replace my blades. And they cost like 4-7$.

I know you probably dont have any way to know, but aluminum oxidizes really fast when it comes in contact with air. I kind of wonder how much actual aluminum powder you end up with, and not just aluminum oxide, which is not useful for pyrotechnic stuff.

[CrEaTiVePyroScience]

@htomerif Not really, any form of aluminium will get a very small oxidation layer when exposed it for a very short time to air. The oxidation layer won't get any thicker if you expose the aluminium for a longer time to air. That's just normal for aluminium and will not decrease the performance.. Once the thin layer is formed it will protect the aluminium from futher oxidizing to aluminium oxide.

s'Cuse me,.. but that burned rather crappy; or not ? Should it not burn Brighter ? a bit .

[CrEaTiVePyroScience]

@explosivefreak666 I think you are confusing this with Magnesium , magnesium burns very bright but Aluminnium doesn't burn that bright. There are alot of kinds of aluminium powder some burn very bright but dark german hasn't the tendency to burn bright.

@SIKShow theres nothing wrong with blowing shit up

[willam1992]

aluminium powder by itself is not dangerous neither is iron powder when mixed its still hard to ignite once its ignited it burns hotter then lava but is not in any way explosive

@htomerif yeah, so.. 4nm. I dont think anyone is going to be grinding anything down to 4nm.

[htomerif]

@CrEaTiVePyroScience I guess thats kinda my point though. as the particle size decreases, the surface area increases. I don't know what oxide thickness is, but as the particle size approached it the proportion of aluminum oxide would approach 100%. I can probably look it up though I guess.
