mormanman Posted February 4, 2008 Share Posted February 4, 2008 Well, looks like it's going to be a while until your next shell. You're delusional if you think they're giving back illegal fireworks and mortars to fire them from. If the cops raid a meth lab, and it gets overturned because of an illegal search they're not giving the drugs back. You'd be in violation as soon as they handed them back to you for possessing illegal fireworks. You really have to hope that he thinks that they're class C. Above all else don't volunteer information or you'll just be digging your hole even deeper. All I really said was that the weren't shock sensitive and they didn't believe me. Also, the fire martal said that I might get my stuff back and I'll pray to all the gods to get that stuff back. If I don't get it back I can't do pyro until I'm 21. Also, I have to bring this up.Why did he say that black powder was the most sensitive of the powders why armstrong's mix is like uber crazy sensitive?

Mumbles Posted February 4, 2008 Share Posted February 4, 2008 You have a sliver of a chance to get the mortars back, but the fireworks you can kiss good-bye. No one in their right mind would give them back, especially to a minor. If he does indeed, well a lot of texans would not be happy with what I'd have to say. As for why he said BP was the most sensitive powders. There are two reasons. 1, he was trying to scare you. Or 2, he's a moron. Link to comment Share on other sites More sharing options...

They may believe what they say is true, or they may be know better and be trying to scare you. Man, sorry that you got busted, that sucks. Good luck.

0nE.sh0t.kIll Posted February 5, 2008 Share Posted February 5, 2008 Keep us posted on what happens with your situation and how it turns out and what you get back. I'm interested to hear, because people in my area call the cops for little pressure bombs, so I keep my things small, until I turn 21 that is.

Doubtful. Keep in mind it was a fire marshal, not a police officer. That would make ALL the difference in what charges might be leveled. Also, it was presumably the fire marshal that confiscated his stuff, it's not like it's in a police evidence lockup. A fire marshal would certainly know of any professional pyros in the area - maybe he thinks he's doing a kid (no offense) a favor by placing him where he'll learn how to handle stuff safely, and indulge in his hobby legally?

asilentbob Posted February 5, 2008 Share Posted February 5, 2008 Once again crazyboy25 and I say:Home made fireworks are classed as high explosives! Its possible that you will be let off... but extremely improbable. I estimate the chances of you getting the mortars back at around 5% and the chances for you getting the had been improperly stored HIGH EXPLOSIVE classed ILLEGAL fireworks back as <0.1%... IF you have to bring everything in frount of the court. No idea how many strings the fire marshal can pull and how beefy those strings are. I really hope this doesn't get bad press. Judges when its up to them generally rule similar to the way it has been done in the past... so a couple bad rulings and it becomes more likely that future rulings will also be bad and/or lead to increased legislation.

TheSidewinder Posted February 5, 2008 Share Posted February 5, 2008 Dunno about where you two live but home-made fireworks here, in Minnesota and in neighboring Wisconsin, are classified as Low Explosives, and have to be stored in a Federally permitted LE or HE magazine. (Local or State regulations may restrict it further.) I think the only exception is "bulk salutes", which have to be stored in an HE magazine only? Or am I confusing regs again?

asilentbob Posted February 5, 2008 Share Posted February 5, 2008 In Texas without a proper manufacturing license it has to be classed as HE as I understand it. Now with a manufacturing license and a registered storage magazine for 1.3g and everything logged and stored per the current national/state/local regs, it would be fine... Aside from the fact that he was setting stuff off under the wrong circumstances. But yeah he can't get a license or magazine yet. If he networked a bit he might be able to find someone willing to share their magazine and property so he could perhaps manufacture on their property under their supervision then store in their magazine and shoot on their property again under their supervision. However I'm not entirely sure what if any regs cover that. I would think that fire marshals wouldn't mind in that case due to the supervision of a more experienced licensed pyrotechnician though. Without license and magazine there are still some club events where the club manufacturing license will "umbrella" it. And probably other situations like manufacturing as a worker in a company. I suppose we'll just have to await the ruling. Link to comment Share on other sites More sharing options...
Mumbles Posted February 5, 2008 Share Posted February 5, 2008 It might be an insurance thing, but everywhere I've talked to doesn't allow manufacturing, handling, or shooting of 1.3g for those under 18. I believe this is the age to get an employee possessor license, so it may have something to do with that. Frankly, it doesn't sound too serious to me. They'd be giving out more than a citation for presumably illegal discharge of fireworks, if they were really concerned. I would imagine that the ATF would be involved, to at the very least try to to scare you. Link to comment Share on other sites More sharing options...
mormanman Posted February 5, 2008 Share Posted February 5, 2008 Bob, I do understand that this could escalate quite a bit and I could be in serious danger with the law/government. And with the mortars and devices; I'm just saying that I hope that I'll get them back. Mumbles made a good point by saying that I would get more than just a citation. I would have been arrested if the guy wasn't nice and cool about everything and if he would rather be asleep. I'm also glad ATF isn't involve (knock on wood). BTW, about being taught by a Professional Pyro, I'm just telling you what my mom told me what the fire marshal told her. Oh yeah, I forgot to tell you guys what I managed to shoot off.2 D1 comets1 TT comet1 3" aerial shell5 starmines some TT, blind reaper silver, D1 and White star comps. They were nice and I started small to build the suspense and I was waiting for my mom. Kinda glad she wasn't there now. Link to comment Share on other sites More sharing options...
rocket Posted February 6, 2008 Share Posted February 6, 2008 Hey guys what do you think about making bismuth trioxide from bismuth metal. Seem easy enough thought wether the metal will dissolve it nitric easily is another thing. If I could order it in I would but it’s too dam expensive.

oskarchem Posted February 6, 2008 Share Posted February 6, 2008 Hey, guys, I was wondering: Would it be possible to make nice blue stars by using just Copper Oxide (II)+KClO4+S+Dextrin? Would this make an acceptible blue? If not please tell me so I dont buy evrything and then not be able to make nice blue. Thanks Link to comment Share on other sites More sharing options...
TheSidewinder Posted February 6, 2008 Share Posted February 6, 2008 All the blues I've seen have more ingredients than that. Here's the simplest one I could find with just a little searching. It's listed as Shimizu KP#2. Formula is in percentages by weight: Potassium Perchlorate 66.5 Copper(II) Oxide, black 13.4 Red Gum 9.9 Parlon 5.4 Dextrin 4.8 No idea if this makes a "good" blue. I haven't tested it. Maybe someone here has, and can comment. Link to comment Share on other sites More sharing options...

qwezxc12 Posted February 6, 2008 Share Posted February 6, 2008 I've shot both Shimizu's Blue #1 (Cu(II)CO3) and Blue#2 (CuO); they are both "acceptable", I guess. I think they are about as good a blue you're going to get from KP without more exotic Chlorine donors like Dechlorane, etc. I also used Shimizu's B-70:Potassium perchlorate........63.80% Red gum..........................9.50% Cupric oxide......................12.90% Parlon...............................13.80% Dextrin.............................+4.00% I think the additional Parlon helps with the deepness of the color, but YMMV. Conkling also has two formulas (KP#1 & KP#2) that are very similar, but I have no experience with them. That said, if you can get it and can deal with the potential incompatibilities, I think AP renders a far superior blue. Link to comment Share on other sites More sharing options...

TheSidewinder Posted February 7, 2008 Share Posted February 7, 2008 That's a quote from a different post. Go and read my reply to your other question there. As to the Red Gum, the precentage is so small that I don't think it's there as a fuel, but rather as a binder. It may be needed to make it all stick together acceptably well. You could probably substitute SGRS for all the Dex and Red Gum, but you might have to experiment a bit to get it all right. Link to comment Share on other sites More sharing options...
