If you want to get arrested then you are going the right way about it. We do not discuss high explosives on this forum. Period.

[thatthing1]

point taken, it was just an idea. I'll have to come up with new idea's then on what i'm using to make it more interesting, I've heard Strontium Nitrate and magnesium powder is a good coloured flash any one know a good composition. cheers

[Jerronimo]

Omg you're asking questions about HE(forbidden) and flash, and you have 3 posts on this forum.
Have you got any experience with this sort of stuff?
Strontium nitrate is hygroscopic, so it will attract water from the air.
Water and uncoated Mg absolutely don't go together, and a mix with a hygroscopic oxidiser even makes things worse.

I've a lot of expirience with his potassium perchlorate but I find his potassium perchlorate isn't cheap, is there a cheaper supplier for potassium perchlorate? (in Europe!). It's very good stuff, but not cheap.

I've found a supplier from fireworkchemicals and he asks me $200/25KG bag, it's a very good price, but it comes from Asia and I think the shippingcosts will be very hughe.

$8 per kilo is pretty good but its only $2 a kilo from nitroparis

Depending where you live, the shipping from Nitroparis will also cost some. I requested a quote some while ago, and I remember that the shipping here was going to be 200€ regardless of the amount of chemicals.

Just had a quick look at their website, it looks extremely expensive. It is around 10x the price I would pay for most of the listed chemicals and fuse etc and I think I pay over the odds for being a private individual and not a company.

for example, fast shotgun fuse £6.00 for 2m I pay £0.62, 4m of flying fish £12 I pay £1.86. Acetone £7.32 for 500ml I pay just over £5 for 5 Liters from a local paint supplier, again Xylene 50ml for £7.12 I pay £4 for 2.5L from a local paint supplier. Flash grade aluminium £8.56 for 50g I pay £21 per Kg and thats well over the odds. About the best value from the site is the ammonium perchlorate as that only about 4 x what I pay

nice to see some one keeping an eye on prices i resort to using sodium nitrate and rolling my own cases anyone uk/ midlands interested in comparing prices and bulk buying to keep costs down?????

[trekkie]

i DON'T KNOW ABOUT PURCHASING AMMONIUM NITRATE FOR MAKING H.E BUT DO ANY OF YOU LOT KNOW WHAT THE MAXIMUM ORDER QUANTITY IS FOR BUYING CHEMICALS AT HOBBYCHEM. YOU SEE, THE THING IS, SOME MONTHS BACK i BOUGHT 300G OF GERMAN DARK, 250G OF SULPHUR, 100G OF MAGNALIUM AND 200G OF POTASSIUM PERCHLORATE, THE RESULT WAS THAT i GOT MY DOOR BASHED IN BY THE POLICE. i ALSO BOUGHT SOME DEXTRIN BINDER FROM THE THE CHEMICAL SHOP. ANYWAY, I WAS ARRESTED AND MY COMPUTER SEIZED ALONG WITH THE CHEMICALS AND HELD FOR 10 HOURS IN THE CLINK AND THEN RELEASED ON BAIL. I FELT I NEEDED AN EXPLANATION FROM HOBBYCHEM BECAUSE I BELIEVED THAT THEY HAD DUPED ME AND ALERTED THE POLICE ABOUT MY PURCHASE. I WAS ALSO TOLD BY MY SOLICITOR THAT THAT WAS PROBABLY THE LIKIEST EXPLANATION FOR MY ARREST. TWO MONTHS LATER HOWEVER, I WAS TOLD THAT I WOULD NOT BE FACING ANY CHARGES. IN THE MEANTIME, I HAVE GOT TO FIND £500 TO HAVE A NEW DOOR FITTED FOR WHICH THE POLICE ARE RELUCTANT TO PAY FOR. THE THING THAT REALLY FRUSTRATES ME IS I'VE ONLY BEEN IN THIS HOBBY FOUR MONTHS AND I'VE ALREADY BEEN ARRESTED, NOT TO MENTION FEELING DRAINED WITH FRUSTRATION AT WHETHER I SHOULD QUIT OR NOT, NOW I KNOW WHY SOME OF YOU DIEHARDS PREFER FERTILIZERS AND MILLING TO BUYING THE BLOODY STUFF.

[RangerOfFire]

For those who want to read the above post, here it is in coherant form:

I don't know about purchasing ammonium nitrate for making h.e but do any of you lot know what the maximum order quantity is for buying chemicals at hobbychem?

You see, the thing is, some months back I bought 300g of german dark, 250g of sulphur, 100g of magnalium and 200g of potassium perchlorate, the result was that I got my door bashed in by the police. I also bought some dextrin binder from the the chemical shop.
Anyway, I was arrested and my computer seized along with the chemicals and held for 10 hours in the clink and then released on bail. I felt i needed an explanation from hobbychem because i believed that they had duped me and alerted the police about my purchase. I was also told by my solicitor that that was probably the likeliest explanation for my arrest.

Two months later however, i was told that i would not be facing any charges. In the meantime, I have got to find £500 to have a new door fitted for which the police are reluctant to pay for: the thing that really frustrates me is i've only been in this hobby four months and i've already been arrested, not to mention feeling drained with frustration at whether I should quit or not...

Now I know why some of you diehards prefer fertilizers and milling to buying the bloody stuff.

[portfire]

trekkie.I suspect its not the quantity (although it probably did play apart) of the materials you bought but,what you bought.The only thing i can think of making with what you ordered is flash and large amounts of the nasty stuff.If (and its a BIG if) hobbychem did alert the authorities,they did so out of concern.Also,four month into this hobby and your ordering chems like that,it may just be me but,it was around a year before i orderd perc.Just me ???


dean

[Jerronimo]

No it's not just you Dean, as the saying go's: you have to learn to walk before you can run.
And you should do just that trekkie, don't even contemplate making or using flash at this early stage in your pyrohobby, you and your stay on this forum will probably not last very long when this is your only objective.
I may sound like a priest, but believe me it's for your own good when you stay away from this stuff until you got more experience with reactive chemicals/formulations.
As a matter of fact I haven't made any flash to this day, and I'm doing this stuff for over four years now.
You will see that most forum members are not interested in making a quick bang, and in my opinion there's no challenge and reward in that.
Fireworks are a art form, and it's the art and science of making BEAUTIFULL fireworks that should be pursued.

[Gazza]

Given that you are new to pyro, your best bet would be to master the skill of making blackpowder, as this is *the* fundamental ingredient in most fireworks. There is a lot more to fireworks than just bangs. In my opinion, being able to produce a deep, vivid blue star formula is far more rewarding than knocking-up a flash formula. Flash does have its place in fireworks (as a shell breaker, for example), but at your stage it would be a lot safer to master the skill of making blackpowder.
