Rooster Posted January 30, 2006 Posted January 30, 2006 d4jon: I see no thread on green stars so I think it would be nice to start one. Here's a modified red organic to burn green. Cheaper to make since barium chlorate and nitrate are not used. Potassium Perchlorate 70Red Gum 9Barium Carbonate 15Charcoal 2Dextrin 4 Rather poor green though. Will have pictures soon. +++++++++++++++++++++++ Mumbles: My personal favorite is a rounded off Shimizu forumla. Barium nitrate 28Potassium perchlorate 48Red gum 14Parlon 5Dextrin 5 The direct Shimizu foruma is:Barium nitrate....................................28.3Potassium Perchlorate.............................47.2Parlon.......................... ..................4.7Red Gum...........................................14.2Soluble Glutinous Rice Starch.....................5.6 It works just as well rounded off, and I don't have to bother with the fractional gram amounts. ++++++++++++++++++++++++ chris17: It's a shame Barium Carbonate often produces a lame green color. I'm a bit affraid to work with Barium Nitrate as it is said to be highly toxic. ++++++++++++++++++++++++ al93535: Just wear a good respirator (not a dust mask!!) and latex gloves. Make sure to wear long pants and a long sleeved shirt then wash them immediately after. KCLO4 is also toxic, although not as much. You should use the above precautions when working with any chemicals though. I sure don't want to even breathe in charcoal dust! The green Mumbles posted above is a really good one! Makes a nice good green! I use the same comp with a few alterations. +++++++++++++++++++++++++ d4jon: I added a percent of parlon. My kclo4 is running low and i don't remember the initial test color and don't know if it helped or not. Here is a vid of the burn with a percent of parlon added. Rather hard to ignite these stars... Movie +++++++++++++++++++++++++++ pyrohawk: Yeah damn it Robert....gosh Sorry I just had to say it Decent lookin green to. +++++++++++++++++++++++++++++ d4jon: Do any of the non-nitrate containing greens work well? I got one with Barium Chlorate 72Barium carbonate 4Red gum 12Charcoal 8Dextrin 4 If anyone has some feedback that would be great. Debating whether or not to buy Barium Chlorate. +++++++++++++++++++++++++++++++ Mumbles: I've warned you about this once before. Only ask the question in one place on the forum. If you do it again you are getting a full warning. This is an exact copy and paste from the random thread. ++++++++++++++++++++++++++++ Swany: Barium chlorate arguably produces the best greens. The reason for this is rather obvious... However it is more dangerous than its nitrate counterpart, as it is more soluable in water. I don't know about acid. ++++++++++++++++++++++++++++ thathad2hurtbad: Haha... Damn it Robert But that does seem like a good and relativly safer way to produce a good green flame. ++++++++++++++++++++++++++++ Mephistos Minion: Damn these colours and their use of chlorates and perchlorates. I cannot wait for someone to be able to ship them here. I have been talking to customs and they can't find anything prohibiting it. Greens here are Zn based. What annoys me is I can get the PVC and Prlond and all that, but no damn chlorates. +++++++++++++++++++++++++++++ Pont: Barium carbonate is readily avaliable in Aus and it can be converted in to its nitrate salt. I have 500g at the moment but its pure as I got it as Barium nitrate. Look at pottery supplys they sometimes even have Strontium salts and Bismuth salts for dragon eggs. +++++++++++++++++++++++++++++ Mephistos Minion: Yeah I have bout a kilo of BaCO3 and am doing a trial conversion at school on monday. The ones I want are Per/chlorates +++++++++++++++++++++++++++ maximusg: Yeah Perchlorates would be very nice down here. I am going to invest some time and money into making a functioning chlorate cell over the next few weeks, now my study load has decreased. I have a seemingly stupid question to ask, but what is Red Gum when refered to in pyro? I keep getting an image of a large tree, is it chracoal made from Red Gum or is it an elastic gum of sorts? +++++++++++++++++++++++++++ optimus: "I have a seemingly stupid question to ask, but what is Red Gum when refered to in pyro?

Here's a page about accroides resin: http://www.kremer-pigmente.de/intl.catalog/37080e.htm TheSidewinder: And to add to the above, Red Gum is used as both a fuel and a binder in pyrotechnics. If it calls for 5% or so, that *usually* means it's being used as a binder (instead of, say, Dextrin). Higher amounts *usually* mean it's a fuel. But that's only a generalization, there are exceptions... M ++++++++++++++++++++++++ Mephistos Minion: Those trees that used to be called "blackboys" contain it. +++++++++++++++++++++++
Mumbles Posted November 19, 2006 Posted November 19, 2006 I have no idea why you think it takes a while to dry. Anything I bind with redgum is dry in a few days max. It's alcohol bound, it should be dry very quickly.
