Shizznt Posted February 12, 2014 Posted February 12, 2014 Nice job for your first shell, but you really need a longer time fuse. it needs to be about 2.5-3 seconds. Did you make those stars yourself or did you pull them out of a consumer shell?What kind of booster are you going to make with chlorate? If you are making flash or whistle then you should get perchlorate.I wouldn't use chlorate for flash because it is unstable. -Ryan
LambentPyro Posted February 12, 2014 Posted February 12, 2014 I agree with Ryan, if that's what you're looking to use Chlorate for, sell it. Your honestly safer with other more common flash with KP. Use Whistle Mix if you're beginning out. It's jusrt as effective IME, and is a non-concussion powder, meaning God forbid something went wrong, it would explode in your face. There are many more effective uses for KP, and it's much cheaper. It does infact seem like you had TT stars and used dragon eggs from a crackling ball. Is this true?
jaysgoh Posted February 12, 2014 Author Posted February 12, 2014 To be honest, I use meal formula cut stars for the stars the stay at beside hemisphere. I grab some cracking stars, not much just 2-4 that's what I left and just throw inside. Was just disappointed that my meal formulary star did not ignite . I might wanna give whistle a try for booster. I couldn't get perchlorate as the price is 2x higher than my chlorate. My chlorate cost me approx usd60/kg and perchlorate need order and the supplier told me is very expensive item. Can I order it from eBay? Does it safe that my customs will check my parcel? Will I get caught when then found chemical inside? My wiper motor seller haven't reply me.. Hope he can reply me soon.
Sparx88 Posted February 13, 2014 Posted February 13, 2014 Still was a good time though right! lol I think you might be a little heavy on the lift charge though, I would subtract 1/4 of the lift by weight and use a longer spollette or ram it much tighter and get it to burn 3.5-4 seconds. 1/4 time fuse is always an easier and reliable option, less work to boot. Make certain that where you glue the fuse it is very well sealed inside and out to help prevent flower potting which is what you almost had happen with this one. I like using 5 minute 2 part clear epoxy for fuse glueing, ready to go in an hour if your in a hurry. Let it cure for 2-3 hours for best result. Small changes go a long way in this hobby. Keep it up! I look forward to seeing more of your work
LambentPyro Posted February 13, 2014 Posted February 13, 2014 (edited) IIRC, KClO4 is prohibited from being sold on eBay. Edited February 13, 2014 by LambentPyro
jaysgoh Posted February 13, 2014 Author Posted February 13, 2014 Okay if aluminium powder? Can I order from eBay? What's the probability that custom will hold my item
jaysgoh Posted April 28, 2014 Author Posted April 28, 2014 Yes it is! It's so expensive! I can get potassium chlorate, aluminium, magnesium from lab supply! Which is hell expensive. Any alternative I can get? But for kno3(3kg for 35usd), willow, pine and unknown wood Airfloat cost me ( 5usd per kilo) I just bought 2 bag of lead balls (300 balls +-) and 7kilo willow, still thinking do I get the right choice of charcoal for bp and should I get pine as well?
schroedinger Posted April 28, 2014 Posted April 28, 2014 Willow should be ok. You could always start to make it yourself. Chlorate from electrolysis, Aluminium from Al foil by using a blender and ballmill. Magnesium by milling magnesium turnings, which can often easly be gotten as pressed brickets. Also magnesium is oftten sold as casted blocks, which can be ground up with a file or used to make magnallium
fredjr Posted April 28, 2014 Posted April 28, 2014 Chlorate gets a bad rap. Despite the common misconceptions it is NOT inherently unstable. Yes more sensitive, & some incompatabilities, but not unstable. Not saying a beginner should play with chlorate, but it does have uses. I certainly wouldn't recommend using chlorate flash for a booster. As for the previous poster's suggestion on milling magnesium, that is a very BAD idea. Magnesium and chlorate would be another bad idea. And wow the prices you mention are insane, at least 12x what I would expect to pay. Also although I can't tell distance in your video, it seems like you are shooting in a city or populated area, that is another bad idea.
jaysgoh Posted April 29, 2014 Author Posted April 29, 2014 Well, I can only get magnesium and aluminium powder from laboratory. I'm shooting at the football field, but it's in resident area.
taiwanluthiers Posted April 30, 2014 Posted April 30, 2014 I don't know how much potassium chloride is in your area but if you can get them very cheaply (look for 0-0-60 fertilizers) you can make chlorate and perchlorate by electrolysis. It's not has hard as it seems and you can produce large amounts of cheap per(chlorate) using the right anodes. For the 0-0-60 fertilizer you will have to dissolve them and filter out the red crap they put in them before using it for per/chlorate synthesis but they work very well and should be cheap. (0-0-60 is 99% potassium chloride with red crap added to it for whatever reason, the red stuff is completely insoluble so should filter out fairly easily) Don't try to mill metal if you don't have to.... I hear stories of sudden flash fire from milling them. You can try to import those because it's not like you're really going to be using a lot of metal powder in a typical comp, and they can be labeled as paint/pigment powder.
jaysgoh Posted April 30, 2014 Author Posted April 30, 2014 Thabks , I try look for ace hardware. Potassium nitrate is not cheap as well. Ace hardware didnt sell any salts .usually mg and al , which of them more useful in pyrotechnics. ?As for charcoal .I can get easily fr China. Just for aluminium powder, I couldn't find flake type. Dont flame me and I m asking. Can I use chlorate whistle mix on 3 inch? I only can access chlorate by today. Actually mcrh got what use? Does it givr out equal power?Thinking of using slow flash , but seems not encouraged .kno3 Al flash can make a good job in slow flash?
taiwanluthiers Posted April 30, 2014 Posted April 30, 2014 don't even think about chlorate whistle unless you want to be a "self absolving bomb technician"
FlaMtnBkr Posted April 30, 2014 Posted April 30, 2014 Have you tried getting your parents to buy the chemicals? Could the shop owner be trying to take advantage of you since you are younger? Those prices are pretty crazy. What country did you say you were in? You could make H3 with your chlorate as a booster. With the prices you are paying you could make devices to produce chlorate and powdered metal. Heck, even one for visco fuse. But they take some knowledge and understanding of how things work. I don't know if it is the language barrier, but honestly you don't sound like you could make them, and then use them safely. Honestly, I would try to put your money into commercial fireworks that you can enjoy. The prices you are paying for chemicals is ridiculous. And if you insist on trying to make fireworks, maybe try smaller shells that use less chemicals and are a bit safer. Or try making small rockets. They can be made completely by hand, don't use a lot of chemicals, and usually perform much better than a similar size consumer rocket.
fredjr Posted April 30, 2014 Posted April 30, 2014 H3 is a good break charge for small shells. But I don't think using it as a "booster" on a BP break charge would be a good idea.
jaysgoh Posted April 30, 2014 Author Posted April 30, 2014 (edited) Yes, I might won't be using chlorate in my composition. For Perchlorate, the price is almost 800usd for 500g lab grade here. It was like Omg, every perchlorate cost more than 600usd.no joke. Maybe it's laboratory grade. I don't think so they scam me man, it's quite rare item here. I might make my shells by this year end and waiting for Chinese new year. So now I am making lot pot lot of stars and bp and spolette and some hemisphere. So that after my exam I will make some 3 inch and mines for Chinese new year How to build soft gold star without Fe/Ti? Any formula substitution? Sorry bro, commercial fireworks is illegal here, I got updated prices by March, 2 inch festival ball x6 cost approx 30usd. And 3 inch 60usd, 4 inch 80usd, 5 inch 150usd per one. They grab it from Thai-land. The prices dropped a little bit maybe it's not 'golden season'. My goal is 3 inch - 5 inch, but 4 inch seems big enough for me as I view live before that my neighbour fire it. So far the most highly useful chemical is kno3. It can be bought quite easily but it's kinda overpriced if compare to United States. Sulfur I can get it at shopping complex and various of charcoal I have to order from China. Shipping fees kill me always. But after my year end exam, I will be super free and might get some works and earn some pocket money to stock up Anyone got idea that one litre of rice hulls equal to how many gram? Chinese people sell it as litre. I bought 6 of them and cost me 2usd Edited April 30, 2014 by gohjiejing
FlaMtnBkr Posted April 30, 2014 Posted April 30, 2014 If you are dead set on building larger fireworks then maybe try contacting a Chinese firework company. Some sell chemicals and will ship small amounts. Much more reasonable prices, even with shipping. If you can't find a company, maybe I can find one. You didn't mention what country you're in?
jaysgoh Posted May 1, 2014 Author Posted May 1, 2014 I try to separate the words to prevent search engine search for the words. MA-LAY'SIA . Yes , its popular country after the incident happened. Nah I dont think so I can get oxidizer from other country, assume that custom check that few kilo of oxidizer and I will get back ground check. But I've add 4 kilograms of kno3 into my cart it cost me 10 usd . And 1 aluminium and 1 mg
