WV-Pyro Posted June 5, 2006 Posted June 5, 2006 I have a quick question. I just recieved my Al powder from pyroaluminum. My question is; should this stuff burn when I light it? When I set some on a sheet of paper and lit the paper, it just kind of glowed real slowly and most of it didn't even burn. Just wondering if this stuff should burn more quickly when I light it? Thanks
Swany Posted June 5, 2006 Posted June 5, 2006 It isn't going to be like magnesium. Mr. Pyro: RDX is a waste of chems , however, go ahead and try it once, as it is quite impressive. I would use the WFNA for nitrating something hard to nitrate, or that could use the conc. acid. Your yeilds would be around 90% with that and a nitric acid ester, meaning about 2.3:1 product:starting material ratio.
mr.pyro Posted June 5, 2006 Posted June 5, 2006 Thanks for the advice, I just want to try it once and knead it into some plastic explosive. I specifically made this nitric for rdx and I can always make some more. I have to find an exact synth for hdn, and thats whats holding me back, all the topics on rougesci, scimadness, etc are hdn-->rdx.There seems to be a thread on it on the old forum, just no exact synth.

Swany Posted June 6, 2006 Posted June 6, 2006 There seems to be a thread on it on the old forum, just no exact synth. Just add hexamine to a nitration bath, or dissolve it in nitric acid until pH is about 5-6, then crystallize. It is basically hexamine with HNO3 attached to amines, I am guessing. So, hydrolysis could be a problem, as in, it could acidify whatever explosive you use it in. You can just nitrate straight hexamine with your acids. It's fairly straightforward, but this should perhaps be continued in the HE section?
mr.pyro Posted June 6, 2006 Posted June 6, 2006 Yes, that is a good idea, I was thinking about starting a RDX/HDN thread. I tried a differnt synth today that also failed.
d4j0n Posted June 6, 2006 Posted June 6, 2006 Well for the grog I'm mostly concerned with my bigger-than-1/4"-rocket-nozzles and plugging larger tubes for fountains and smokes and such. I bought grog from C&A once, someone gave me the suggestion as to which one to buy and it worked beautifully, but I can't for the life of me remember which one it was. I don't think it was 40 mesh...more like courser-than-sandbox-sand type mesh... I don't get what they mean on C&A when they say like 30x50 mesh or whatever...between 30 and 50 mesh?
TheSidewinder Posted June 6, 2006 Posted June 6, 2006 Whoops! I just went to the garage. The 2 bags of Grog that I bought are 30 Mesh. And yes, I think when they said 30x50 they meant 30-50. But 50 mesh is probably too fine. M
Pretty green flame Posted June 6, 2006 Posted June 6, 2006 Hey guys, i'm kinda in a dilema. Can anyone name this "CH3-CHOH-COOH", i really have no idea what this is. Thanks for your help.
Mumbles Posted June 6, 2006 Posted June 6, 2006 2-hydroxypropanoic Acid. It's more commonly refered to as Lactic Acid.
TheSidewinder Posted June 7, 2006 Posted June 7, 2006 2-hydroxypropanoic Acid. It's more commonly refered to as Lactic Acid. Chemistry Geek..... M
Chris Posted June 7, 2006 Posted June 7, 2006 2-hydroxypropanoic Acid. It's more commonly refered to as Lactic Acid.Chemistry Geek..... M General knowledge . I'm actually a bit concerned If that doesn't sound familiar. After all, it is chemistry we are dealing here with.
Rogue Chemist Posted June 7, 2006 Posted June 7, 2006 I nearly was able to do research on what would essentially be magnalium with neodymium added, but after getting the goahead to start, I found in the literature that it has already been done, so I was not allowed to work on it. Could have had some interesting uses/properties...
d4j0n Posted June 8, 2006 Posted June 8, 2006 I can't seem to figure out what is to be baked to dextrin, corn starch or corn meal. Never seen corn flour in stores.
FrankRizzo Posted June 8, 2006 Posted June 8, 2006 Corn *starch*. The flour is used for thickening meat-less chili, making corn chips, tamales, and other intestinal fireworks.
Mumbles Posted June 8, 2006 Posted June 8, 2006 I believe in europe, what we know as corn starch in the US, is called corn flour. I know where you live, and you want corn starch.
Pretty green flame Posted June 8, 2006 Posted June 8, 2006 I believe in europe, what we know as corn starch in the US, is called corn flour. I know where you live, and you want corn starch. Corn starch is Corn starch, even in Europe , atleast that's where i live. Although i have seen people use corn flour and have great succes with making dextrin.
Mumbles Posted June 8, 2006 Posted June 8, 2006 Well, I was specifically thinking of the UK. I thought it was the same throughout the continent. Perhaps someone from there could comment. I am fairly sure it is something different.
Draco_Aster Posted June 8, 2006 Posted June 8, 2006 In Australia it is commonly known as corn flour. I remember in my noob days I just couldn't find ''corn starch'' untill I read an article somewhere (roguesci ?). There is no actual difference between the two. I don't know about corn meal.
Givat Posted June 8, 2006 Posted June 8, 2006 Listen guys, in my country we can't buy pure PVC from pyro shops in a reasonable price.So I looked for some factory who use PVC as raw material. One of the factories was happy to help me and sent me info on is PVC to see if this will be good for my use.The problem is that I don't sure if this is pure enogh or eve nhow pure is this PVC from the info they gave me - so I'm hoping maybe one of you guys can help me determine if this is PVC good for pyro. http://www.apcforum.net/files/060524-2.jpg (In order to see the file you need to right click it and "Save Target As...". after this change the name to "060524-2.pdf" and it will open with acrobat reader) thanking you in advance p.s.This PVC will cost me about 5-7$ a kilo, so if it's good for pyro maybe people should try to buy from factories too.
FrKoNaLeaSh1010 Posted June 8, 2006 Posted June 8, 2006 Am I the only one who has realized that compared to magnesium fueled color stars....any organically fueled comp seems pale and otherwise shit? I always thought organically fueled had a nice color until i tried magnesium ones....they have three times the flame envelope and are a lot brighter and more colorful.
Mumbles Posted June 8, 2006 Posted June 8, 2006 Yep. Metal fuels are becoming more neccesary within the world too. In the origins of pyro there was no such thing as incadescent lighting. The sky has literally gone from black to a dark blue. Thus you need brighter stars to make them more visible. I always thought the samething as you. My favorite red star for a long time was organic. I recently tried Ruby Red MgAl stars, and it puts the other one to shame. It makes it look pink in comparison.
mr.pyro Posted June 9, 2006 Posted June 9, 2006 Well I went to my old highschools graduation ceremony tonight and got to see some nice shells from the fireworks show there. As well I went shopping at Frys and got some Asprin, which is now ASA. 2 bottles of glycerin, cotton balls, and some epsom salt that I plan on using as a dessicant. And from walmart I found some sodium silicate which I have been looking for forever. As well this past week has been good, Rdx was made successfully as well as EGDN and I distilled about 120 ml of HNO3.
_Po_ Posted June 9, 2006 Posted June 9, 2006 I haven't posted in a while, just thought I'd say something. What that something is, I'm not completely sure. Oh, my dad found a big roll of good quality brown paper yesterday. It weighs a good 10kg. There we go...
