  1. I've heard of individuals using hot glue as the endplugs themselves. But I would definitley use the tissue to isolate and insulate the powder from the heat. I'm planning on lifting some 3/4" ID salutes in the next couple of weeks. I'll update you guys soon.
  2. I have personally never heard of an ignition via hot glue gun. I believe hot glue guns work about 120 degrees Celcius. I'm not sure of the auto ingition point of flash powder, but believe most black powders are around 600 degrees. Tissue wadding with a glob of glue should do fine for a fast powder.
  3. You don't need an APC account to view it's contents. Well other than HE, but the tut is accessible by anyone.
  4. Pyrostar I am sorry, but this seems to be a bit kewlish. You didn't mention anything of how you made it except for that it is a mixture of magnesium powder and blackboard chalk You didn't even try to find out what the chalk is definitley made of so that makes it very hard to duplicate for others across the net looking at this. Lastly, we already have a flashpowder thread and a salute thread and don't want pyroforum.nl to be another one of those kewl sites. Please use the threads that we already have and keep the place neat. (To the mods: If this seams out of place please delete.) Anyways. Mg is very reactive. The use of carbonate oxidizers has been proven in other compositions as well. It can also be lit and sustain a "flame" through a block of dry ice. Also, what is this way you found to powder Mg?
  5. Definitley invest in a good respirator before buying any more chems. Obviously you are being exposed to dangerously small metal particles. In the original Wizard of Oz movie the tinman's makeup was made of aluminum powder. He died shortly after do to his lung damage. I do believe it is better to use a less efficient flash than to have to worry about the dangers of permanganate flash. You mentioned you have magnesium powder. Why not try the old 50:50 mix of KNO3:Mg? It has proven well enough for well confined salutes. You may need to get something stronger down the way if you get into crossettes or something, but for a banger you'll be fine.

    Starmine

    Hello all. Last night I had the experience of two starmines. One was 25g of stars and 8 grams lift. The other was a 2" aeriel shell that turned into a starmine. The shell weighed 86g and was lifted with 8g. I spiked it very well (or so I had thought). I believe the problem may have been from a bit too much lift. This is the fastest powder I've ever had, as well as leaving it in meal form. I know rushing is bad, but I wanted to let it fly so bad . Well the intended star mine was more of a color test. I didn't get to see too much color because I never primed the stars and it turned out they definitley needed prim. 3 out of the whole lot was all I seen. It was bleser's organic purple. Unfortunatley, I did not like what I did see. The shell/mine was actually an amazing mine. It was just white (BP based) cut stars. Various sized. I think the burst gave a nice extra flame out of the mortar. The funniest part was when the "casing" of the shell landed in a tree. Good times.
  7. That definitley needed to be milled for a lot longer. No experience with "super-duper fast rye charcoal". Are you talking about Cocoa Powder or BP that rye was the charcoal used? Btw, instead of putting two posts in a row within 1 hour it would be best to just edit your first post.
  8. Where is it you are from? Carbonates can usually be find semi-locally in pottery supply places. Sometimes nitrates even. Great news that your parents are accepting this as your hobby. I'm not sure if I've replied to your situation, but I will. #1 Be honest with your parents. They won't trust you if you don't give them a reason to. #2 Don't scare them. -Show them any injuries and calmly explain the severity. -Don't do anything too big at first -Explain everything to them before it happens #3 Don't take shortcuts Those are the best things I can think of at the moment. I am 19 myself. My aunt and uncle don't mind, but I'm not mass producing flash salutes or anything like that, so things work well. There biggest grips is about my charcoal hands touching the furniture. Good luck.
  9. The black powder thread. Post any questions or comments on black powder here. I am also wondering who likes to take what processes when making their own black powder. Here's my story: I am in the middle of processes right now. I have been using a 3lb rock tumbler style mill with 100 .50 cal lead bullets. I just recently was given (by my girlfriend) a 1/2 HP motor. It's a beast at 24.5 pounds/ 11.11 kg. It is whisper quiet right now, but will operate a loud ball mill I'm sure. Not sure on the size of drum I will be using, but it is going to be moderatley sized. I've got a design thought for my mill to support various sized drums. I'll keep you updated if it goes through. I currently make 100g batches and make pulverone with dextrin added. I use what I believe to be weeping willow charcoal.
  10. Duvel, I believe you are using too much solvent if you are having the KNO3 recrystallizing out of the mixture. This is a big problem with stars and the process is called driving them in. Try using less water/alcohol mixture and compare them. Using 6-10 percent water and force it through a window screen helps spread the moisture evenly.
  11. I had a nice long post all ready and I lost it. Here's the jist of what I said: Willow is good enough. How'd you make you're charcoal? What kind of mill do you have? Pulverone will slow down BP if a binder is used. Look into a BP die. Here are the charcoal tests: http://www.creagan.net/fireworks/charcoal_tests.html Sorry for the tone, just mad because I lost a nice long post and am in a hurry.
  12. There is a magnalium post in the english section so I guess any further posts on that should be placed there. Yes your composition is defninitley going to be too slow and hot(temp) for a fountain. I tried a comp a little bit ago. KNO3--------------65 Sulfur--------------15 Al Atomized-------15 Charcoal-----------5 Well what happened was it was TOO slow. Had a nice white portfire with some sparks shooting up randomly and then it burned throught the tube wall. A loose pile burning had a strobe effect, that was cool. I think it would work well for a cake insert comp though. Remember a fountain needs thrust to expel the effects out of it. Many times effects are: metals charcoal chunks largish sulfur prills dragon eggs very small stars as well as other things. Keep on working out your plans and figure out why some things work and others don't and you'll be able to fix and modify many comps to your liking. Patience and practice are THE key.
  13. That actually was not a glitter fountain. It was just meal with Mg chips placed randomly in it. Goes to show how simple things can be. I don't think glitters would work very well in close up. Part of the glitter is due to how far away they are. Starmines with glitters are pushing it even I think. Kind of how stars lose their characteristics of twinkling when there only a few million miles away compared to trillions. I believe D1 is a promising fountain comp but would not glitter with the adjustments needed for the thrust. You'd have to get rid of most if not all the bicarbonate and maybe up the nitrate. Meal+metal works fine in the beginnings.
  14. Mr. S, that must be one good dinner to last this long. The american school system starts at "kindergarten". Following is 1st through 12th grade. When one enters Kindergartern they are age 5 and usually 6 upon graduation. So when 12th grade goes by they enter as 17 and graduate at 18. I made a mistake back in the 6th and am going to graduate at 19. K-6 are generally elementerary school grades. 7&8 are junior high school. Some school districts end elementerary at 5th and 6th through 8th are called middle school. 9-12 are high school. Once in high school there are also titles for whatever grade you are in. 9=freshman, 10=sophomore, 11=junior, 12=senior. The same names are given in college, but instead of 13-16 it is 1st-4th all over again. I don't know why I typed all that, as Prophet said, "It isn't THAT important."
  15. I definitley do not take it as an attack on myself. I also definitley do not claime the saying "stay green" to be something I came up with. I was just reading a lot of back issues of PML and many people sign off with that saying. I normally don't say it myself, but it just came out. I believe it is in reference to the green man as well as the adopted slogan for the Pyrotechnics Guild International. The following is taken from the pyrotechnic glossary at pyrouniverse.com
  16. Yes, it seams that quite a few people on this forum speak english very well. Well type it well at least. That channel is not connected with APC, but some of the regulars are part of APC. Some actually don't like APC at all. What is this forum's channel?
  17. Well I'm not asking for HE I was just getting it out there that there hasn't been a little of talk and probably wouldn't be a necessity if more sub-forums were put into the english section. Is pr0n the same as porn? If so then no, not my thing. Yes, I'll stop by the irc channel once in a while. Frozentech is who showed it to me I believe. I very much respect the regulars there and find it a good place if a specific question is bugging me. As for learning Dutch. I don't think I'll be putting that on my to-do list. I tried learning french for 5 years (well through the american public school system) and that didn't turn out too well, not too bad either. I think if need be I'll ask a mod to translate, thanks for the gesture by the way.
  18. It could be. I'm not sure what other sub-forums are available in the Dutch section, but I don't see a lot of enthusiasm here for HE. Maybe compositions and such for the English though. Otherwise the section will be crowded eventually.
  19. So this isn't the same as an introduction thread. More of a summary of your experiences as a pyro. We don't need another 15 chapter "Diary of a Pyro". Here you can include whatever you want about yourself as a pyro and just as easily omit what you don't want known. This is just to get a better understanding of our community. Name: you can call me deadman Age: 19 The rest: Well I first got into pyro very young. My babysitter showed my the hairspray+lighter trick when I was about 7 years old. I freaked out the first time she made me do it, but went home and did it again. In the 8th grade (13-14 years old) I started reading archives of the explosives and weapons forum. I also unfortunatley got a digital copy of the anarchist cookbook. Within a year I was making smoke bombs and such. Also the occasional backyard petrol fires. A friend had a sandbox from when he was little and we poured petrol on the sand and lit it, then proceeded to flip the gas at eachother creating small fireballs that went out when they hit you. I went through a troubeled stage and skipped school one day. Two friends and I went to one of their houses and had a sparkler fight. Occasional match wars at night as well. Burned holes in our shirts and his linoleum floor. Then my friend John and I went through the arson stage. Arson victims include a small dead grass field next to my elementerary school, a truck that had dead brush in the back, and finally the (thank god) demise of my arson stage a trash can at a local department store. After lighting the trash can on fire we ran across the parking lot into a Toys R' Us and started playing video games. The local authorities had us in handcuffs promptly. Then I took a break and only read for quite a while. With a new sense of maturity and a job, I started true pyro. I also had moved to Bakersfield during this time. Mojave desert in California if some aren't familiar. Very hot, dry climate during the summer. Low rain during winter and when it does it's thunderstorms. I got my KNO3 in the form of stump remover. My cousing who is an avid hunter gave me a few pounds of smokeless powder. I then bought a rock tumbler/ball mill. Bought sulfur at a local hydroponics store. Tried activated charcoal . Had to make my own not great but better. Acquired more and more chems. Started making fountains, rockets and other true pyro devices. Then I got into flash salutes for a little while. First permanganate that I got for free from my school, then perchlorate which I ordered. Time marches on. Upon turning 18 I moved back to my hometown Salinas. Near the monterey bay in California. Now I use eucalyptus charcoal (sucks for lift btw). Started making stars here. Got into aerial shells and the more advanced parts of pyro. Also I bought a real set of pyrotooling a la Greg Boyd. Things are going much better than my doubtful beginnings. Well either that's all I have to say or I'm tired of typing. Let's see what others have to say. Edited to change birthdate.
  20. It is definitley more internationally friendly although I'm not familiar with the .nl format other than to this site. But who can argue with the great information and discussion found here. I only wish I spoke Dutch to be able to read the other posts.
  21. Just wanted to say I am enjoying the new url of www.pyroforum.nl Also recent activity in the forum is always a mood maker. ;)
  22. News: It appears that Cu/Al thermite in a (44:10) ratio is sensitive to .22 caliber rounds when confined in as little as a film canister. Great news, great news. Now this has not been confirmed by myself and may prove to be untrue in which case there will be more news. Stay green.
  23. Due to the recent mention of traditional and other thermites I started this thread. Black Iron thermite is considered the norm from my experience. Red thermite is about the same cost, but loses some of the energy the black iron is common too. I mentioned I really like CuO thermite, it is extremely fast in fine powdered state. Faster burning than good BP actually. Blackwolf mentioned that CuO is one of the more energetic thermites. Yes it is but there are much more vigorous reactions. Such as the heavy metal thermites we all love known as dragon eggs. Red lead is a very destructive thermite that I would probably guess to be one of the most violent thermites around.
  24. To not distract from that at hand topic I am going to make a new thread: Thermite(s). If a mod could please move some posts from this thread to that one it would definitley help keep things clean. ;)
  25. What kind of thermite are you wanting to make ucki? The traditional Fe3O4? I don't know why, but I love the CuO thermite. I use ceramic grade.
