Unknown Powder
I went to mexico last friday, and i picked up some polumas. I emptyied a few, and since it looked and burned like cheap whistle powder in the open, i decided to make a whistler. I got about 1/2 teaspoon of it, and packed it into a really thin tube, no more than 1/32 inch thick. The plugs were really crappy, becuase all i did was pack tissue paper into each side. When it went off, it made a very loud boom. Does anyone have any idea what this powder could be? It is white(no crystals, so i dont think it could be AP) and it burned a little fast but very feircly in the open, and it doesnt cake when pressed. I am thinking it could be HMTD, but anyone else have ideas? Thanks for any help.

Re: Unknown Powder
����Possibly some sort of sugar based flash powder. I severely doubt that the Mexicans are packing their fireworks with explosive peroxides.

Re: Unknown Powder
I went to mexico a while ago and I ate a burrito. I broke the number one rule in border towns, NEVER EAT FOOD IN MEXICO. Try to avoid the water too. That said, I don't really have enough info to make a determination to what this is, but it's probably just some sort of cheap flash.

Re: Unknown Powder
i only went no more than 5 miles from the cali border.
I do think it could be a peroxide, becuase i was packing it pretty tight, and there was very little confinment. It is hard to get a sugar based comp. to explode, and sugar easily cakes, and this powder didnt cake at all.

Re: Unknown Powder
do you think they would put AP in polumnas? I think that's a little too dangerous.
PS- I was gone for a few days but I'M BACK

Re: Unknown Powder
����Still. Why would they go through the effort of synthesizing a peroxide when flash powder takes less effort and can be stored for far longer.

Re: Unknown Powder
it for sure wasnt flash powder, becuase there werent any sparkles in the powder. All it was was a plain white powder, so that is why i asked.

Re: Unknown Powder
I'm sure it's not something like AP also, they aren't that dumb...
Just from what you've said, I'd guess whistle (it needs to be packed pretty well, so if it was whistle, thats why it exploded instead of whilstling) or maybe chlorate/perchlorate and sugar.

Re: Unknown Powder
i did pack it really tight, like whistle powder should. It could be chlorate and sugar, i forgot about that, but you usually shouldnt pack the powder for it to explode.

Re: Unknown Powder
There are no 'sparkles' in my flash powder, it's a homogeneous mixture that explodes with a flash and almost no sparks.

Re: Unknown Powder
i think he ment that the powder didn't have anything metallic in it therefor it wouldn't sparkle/shine/glint/reflect when light fell on it.

Re: Unknown Powder
����High mesh flash powder doesn't really sparkle anyway. The metal particles are too small to be reflective to the naked eye, and the stuff is just plain grey if german or indian black aluminum powders are used.

That's the whole 'homogeneous mixture' part of what I said. Homogeneous, in this case means the individual parts of the mixture are indistinguishable from one another.
