fred815 Posted July 29, 2011 Posted July 29, 2011 I'm so new I've got to reply to something before i can ask a question. There I replied so my post will be coming!!!!!!! TA DAA
Stargazer Posted October 19, 2011 Posted October 19, 2011 Hi All. I'm also a newbie, at least to this site. I'll try to not do that newbie thing of searching for five minutes, then asking really really dumb questions that are discussed elsewhere. My first post ever!
Dr Boom Posted June 23, 2013 Posted June 23, 2013 Might I suggest the chat room here also? Sometimes you can lure the old folks in there with coffee and hopes of beef jerky or fishing stories. Most of the time pyro is discussed

Pyro011 Posted June 27, 2013 Posted June 27, 2013 Hi All from South Africa Im a Complete noob to this but im really interested in learning all I can.
corvus777 Posted July 6, 2013 Posted July 6, 2013 hello im new to pyro, only been doing it for 2 weeks now, I cant seem to get my stars to light from the burst, any ideas?
Seymour Posted July 6, 2013 Posted July 6, 2013 (edited) Yep, but I need more information to narrow it down. Welcome to the forum  What star composition? Are they primed at all yet, if so, what with? Edited July 6, 2013 by Seymour
corvus777 Posted July 8, 2013 Posted July 8, 2013 i used the formula from skylighter.com for red rubber stars i primed them and everything i can only get them to light 1-2 out of like 30 stars in a shell im doing 2" shells with 4:1 bp rice hulls, im wondering id their is too much humidity where im at so i built a star dryer to see if it helps, so far put em in the dryer for 3 hrs and it still takes like 7-11 sec with a lighter to ignite them

Sometimes you can lure the old folks in there with coffee and hopes of beef jerky or fishing stories. Most of the time pyro is discussed . Oh yes Dr, all of the people in chat are old and only will break out the fishing stories when we have our first cup of coffee in the mornings . But seriously , if any of the newbies need anything answered they are more then welcome to hop of chat and ask , we don't bite Edited July 8, 2013 by pyroman2498
User64 Posted July 8, 2013 Posted July 8, 2013 Is there any literature or articles that delve into the science aspect to help the reader understand how different combinations affect the outcome of the intended build ? I'd rather understand the science first by knowing how certain compositions should perform and being able to make knowledgeable changes if the results aren't what were being sought before spending one single penny on anything.
pyroman2498 Posted July 8, 2013 Posted July 8, 2013 IF i'm understanding this correctly , i would recommend taking a look at the pyrotechnica books , Fireworks: The Art, Science, and Technique, and maybe the , A Professional's Guide To Pyrotechnics: Understanding And Making Exploding Fireworks. those are some good reads to look at anyway.
Shadowcat1969 Posted July 8, 2013 Posted July 8, 2013 i used the formula from skylighter.com for red rubber stars i primed them and everything i can only get them to light 1-2 out of like 30 stars in a shell im doing 2" shells with 4:1 bp rice hulls, im wondering id their is too much humidity where im at so i built a star dryer to see if it helps, so far put em in the dryer for 3 hrs and it still takes like 7-11 sec with a lighter to ignite themWhile I am not as experienced as a lot of people here, I would say that moisture in the star probably isn't your problem, if the prime isn't lighting for 7-11 seconds (BTW, I would NOT use a lighter to test them, that puts you too close to them when they do ignite). I would probably suggest adding another layer of the 50:50 outer prime as described by Skylighter, and maybe even a layer on top of that of 100% Black Powder.
User64 Posted July 8, 2013 Posted July 8, 2013 Thank you pyroman, I'll start with those. I just want to understand what should happen and how to change things if they don't before buying anything.
pyroman2498 Posted July 8, 2013 Posted July 8, 2013 No Problem dude,Thats a good idea, learn as much as you can before you start building, Its the way i wish i would have started...Anyways,Stays Safe, ~Steven
Zumber Posted July 8, 2013 Posted July 8, 2013 Hello, just getting my first post out of the way.welcome to the forum Rogcat33...!!
Mumbles Posted July 8, 2013 Posted July 8, 2013 User64, that is actually sort of a hard request. Really understanding how things function is a combination of knowledge of the effect, as well as practical experience. Much of the knowledge within pyrotechnics is empirical, and doesn't have as much theoretical underpinning as some (myself included) may like. You can read as much as you want, but it really wont do you a lot of good until you start getting your hands dirty and get some experience. That said, there is some decent literature that approaches things from a more scientific angle. Fireworks: the Art, Science, and Technique - Dr. Takeo ShimizuFireworks from a Physical Standpoint - Dr. Takeo Shimizu (actually a 4 part series)The Pyrotechnia Journal Series (17 issues total)Pyrotechnics - Dr. Alexander HardtChemistry of Pyrotechnics - Dr. John Conkling
ChloRure Posted July 8, 2013 Posted July 8, 2013 Those red stars use acetone and dont really trap water.. You can even test them while they are not dry. When I did them, I primed them with pinball prime then a greenmix bp with 8% silicon as second prime, they took fire easily in a shell.
coffman34 Posted July 9, 2013 Posted July 9, 2013 First post. I have a question on the ATF's magazine storage. Do you have to store all finished fireworks in a magazine? Or is it just the chemicals used to manufacture them. I ask, because I have the ability to hold a separate magazine in another building away from where I can make them. But I want to make shells and save them all for a show for a party I do every year in the back yard. If I I have to store them all in a magazine, I just didn't know how many I would be able to store with the 50# limit. I only plan on doing 3" shells tops. Thanks, and sorry for the hijack.
flying fish Posted July 11, 2013 Posted July 11, 2013 That is sort of backwards... raw, unmixed chemicals (potassium nitrate, etc...) do not require storage. Live pyrotechnic compositions and completed fireworks do require storage. The 50# limit is the net weight of powder, so you might be able to do more with it than you think.
Mumbles Posted July 11, 2013 Posted July 11, 2013 Typically a standard approximation is that you assume 50% of a shell is live material. If you assume that an average 3" ball shell is 150g or so, then you can account for 75g of live material, which works out to approximately 300 3" shells. 1
unsilentninja29 Posted July 15, 2013 Posted July 15, 2013 I been clicking on links but they seem they don't ever wana load, im using internet explorer , and was wanting to make some shells next year in a 3" ball, Was looking for some advice for beginners?, and books also, but like I said I tried clicking links and wasn't loading maybe its my explorer?
