thermite trouble

— Posted by minibus on 2:12 pm on Feb. 3, 2002

I found ferrooxide (I am not sure if it is ferro II oxide ) and mixed with with a very little amount of very well grounded aliminum powder (it has a silver color and supposed to be 99% pure) and i heated on the spoon till the spoon gets red (means more than 150 degrees I guess) but nothing happened?! Even the ratios are wrong they should have been reacting, as far as I know from chem. lessons.. can anyone enlighten me?

— Posted by Nquizitif on 6:57 pm on Feb. 3, 2002

Well you’re missing a very important part of the recipe – something to start off the reaction which requires higher temps than you said.
See if you can get some magnesium strips to stick in it and light these, these are lit at much lower temps but the reaction of the magnesium strip burning gives off temps high enough to ignite aluminium and iron oxide mix.

However, i have tried this a couple of times and it hasn’t worked so i can’t really talk from practice! Try it out and tell me if and how you got it working.

Try some of the older posts in which i asked such questions before! Maybe search for ‘thermite’ in the titles for ease!

Good luck!

HAHAHAHA!!!! owww my sides hurt! lmao!!! oh jeez what a newb! lol “i heated it over a teaspoon” ahahah!!! my god!!, no thermite rules! you sux!! :biggrin: oh god! haha!!! also it doesnt even sounds like this shit that you used for AL was even anything close! LOL “it has a silver color” hahah!!!

— Posted by Sicopath on 1:46 am on Feb. 4, 2002

Several things wrong,
You have to heat the mixture in a cast iron pot until the mixture becomes a red color.
You need a magnesium strip to light the thermite.
you need a hot blowtorch to light the magnesium strip.
Thermite does not blow up, it flares and burns through stuff.

Milenko, I really feel the reduction-complex out of your words.. I bought Al powder from a chemical store that sells to universities and labs.. we checked the purity of it from several catalogs and add-on guidance book. Now, if u wanna laugh at smth, choose smth that wont make ppl laugh more at your smart-arse stuff.. I just asked for help, not moronity..

— Posted by r3ntin on 10:56 am on Feb. 4, 2002

try maybe starting it with KMNO4 and glycerine. glycerine must be kinda pure though, none of that beauty shite.

— Posted by Zambosan on 3:17 pm on Feb. 4, 2002

Hey r3ntin… I had that same thought years ago when I was trying to ignite thermite.  It burns hot, but not hot enough to ignite thermite, unfortunately.  However… there is hope! 🙂  I also tried magnesium, but it turns out you need a good deal of magnesium to really get a chunk of thermite to go.  You can get magnesium firestarters at camping stores & shave of a bunch of it & either use it “straight”, or create a subigniter by mixing it with sulfur and a *little* bit of cornstarch to bind it together.  However, it’s actually even easier to get a sparkler or three, clip the wire at the base, jam ’em into the thermite charge and light them off.  They *must* be the gray metallic ones… these are made of thermate, which is thermite sensitized with another oxider (usually a nitrate, military TH4 uses barium nitrate which is toxic due to the heavy metal).  These are a pain to light too, but will burn plenty hot to initiate a thermite redox reaction, and make for a nice time delay to boot.  Caution: get the f**k away from the thermite charge!!! This reaction is unbelievably fast, and burns hot as hell!!!  You should be rewarded with a few lumps of white-hot molten iron if all goes as planned.  If you have trouble getting iron oxide, jeweler’s rouge (red iron oxide) is a potential source… it’s what I used.

right i know you is all gonna probbly  call me so much nasty shit for sayin this that ill be forced to migrate to a dark secluded place where i cant get the shit beaten out of me 🙁

…but how do i make ferrous Fe3O iron 3 oxide basically, i mean its meant to be rust but rust is only iron oxide not iron 3 oxide,

pleez help me out on this:biggrin:

— Posted by Hergor on 4:54 pm on Mar. 4, 2002

thermite works with FeO as well.

i don’t know how you could make Fe3O out of FeO but Fe3O can be bought in form of ‘triferrous-monoxide-fertilizer’ or just ‘iron-fertilizer’ from garden stores…

usually rust (mainly FeO) contains Fe2O3 and Fe3O4, too. those give you an extra ammount of oxygen, so it oughta work… 😉

— Posted by darius on 4:59 pm on Mar. 4, 2002

thanks a lot man , looks like il have to be a lil mor persistent with the stuff then cos it aint goin nowhere!!:biggrin:

— Posted by darius on 5:05 pm on Mar. 4, 2002

know its low replyin to my own post but i forgot to ask before:
is there any way in which i can light the thermite using household materials and stuff,  cos i am in the u.k and it is really difficult to get hold of Mg and first fire compounds etc.
thanks for the help again:)

— Posted by Hergor on 5:07 pm on Mar. 4, 2002

i don’t know, maybe acetylene (welding gas) works.

it (thermite) needs to be heated above 1600 degrees celsius [around 2900 degrees fahrenheit] i think…

— Posted by Darkie on 5:19 pm on Mar. 4, 2002

Any one ever made thermite before? how did it go?

Also, do i need to melt the Al and FeO together or just leave it as a pile of powder?

— Posted by darius on 5:26 pm on Mar. 4, 2002

yup i made the shit and if youve read above a bit youll find i dint get too far with it,

but SHIT NO DONT MELT IT jeez man if u start melting them together your gonna start the reaction and melt a hole through whatever you tryed to melt them in!:)

yeah i heard that the shit can burn through an engine block.

this is stoopin low replyin to my own message but i forgot to ask: is there any other way that i can light thermite without Mg or first fire

like can i use household stuff cos i am in the u.k and cant get hold of any of the stuff you guys sid to use…

Try sparklers or the old fashion type of flash bulbs(contain Mg)

— Posted by dellexo on 4:32 pm on Mar. 6, 2002

By the way,you can bye the stuff in the U.K.Do a search for Cadweld,this is thermite but it comes in different grades.One turns to copper used in cable joining and one that is used for welding rail tracks wich turns to steel.

— Posted by darius on 4:32 pm on Mar. 6, 2002

cheers dellexo, but i tried sparklers and it didnt work , i even mixed sparkler dust in with the thermite so it would all go up.
…but still nothing, maybe it isnt in the right proportions?

i used something like 60% FeO and 40% Al

— Posted by zack2482 on 8:48 pm on Mar. 7, 2002

Hey i was wondering you heat the thermite in a cast Iron pot but over what. (a stove, fire).

I’m pretty sure either will do, it doesnt have to be an exact temprature, but i could be wrong, and i’m talking about cypher, pyro131313, although he knows i’m only playin’ 🙂

— Posted by zack2482 on 10:51 pm on Mar. 8, 2002

thanks alot man i apriciate it

— Posted by Strayel on 6:17 pm on Mar. 9, 2002

Make thermite a bit easier, try

Nice one mate:biggrin: A nother site which sells AL powder in the U.K. is http://www.cfsnet.co.uk Bought some last week,8 quid for 1Kg :biggrin:

get steel filling put in water and a little bit of salt, then place to COPPER wires into the suloation. conect the two piece to  a battrey charger and a let it go for about three or four days. You drain the water and get this black shit. You heat it until it goes bright red(when hot) dark red (when cold) “FE03”

— Posted by Orion85 on 10:26 pm on April 2, 2002

wait. so a sparkler will light thermite? thats a lot easyer than trying to steal magnesium, and iv never heard of a chemistry store around by my town. So is it true? I don’t know what temp sparklers burn at. yea-and which sparklers if they do work?

— Posted by guzzetti on 7:54 pm on April 3, 2002

What are the poportions of Iron oxide to Aluminum. What can I subsitute for Rust and how do i make it. Email me the answer.Plese.

— Posted by Badassmf on 11:59 pm on April 3, 2002

in order to set termite off it has to be REALLY hot your not gonna fucking set off thermite with a blowtorch you need Thermite,a magnisum strip, and a blowtorch

stick the strip in the thermite light it with the torch and get the fuck away when i say this i mean dont set the shit off while its in your hand cause it wont burn your hand it will fucking vaporize it

— Posted by mrjingles on 9:11 am on April 7, 2002

hey it seems like evryone thinks that u need a blow torch to light mg , i stole some from school and lit at lunch all i has was a normal bic lighter and it did the trick it took a while though, around 30 seconds or maybe a lil more but a sparkler would light it in a jiffy or use a jet lighter them lighters that burn heaps hot with a fully blue flame….

— Posted by Joshbdaman on 9:35 am on April 7, 2002

I have all my thermite made…40%AL 60% Fe03…. To set it off, could I use a torch? You know, the shit you use to cut metal by using a very fuckin hot flame. It literally melts the metal.

— Posted by paladinpress on 9:42 am on April 7, 2002

For what you have josh yes, that shit aint gonna go off with not Bic BUT I assume you have AL of less then 200 mesh I have made AL powder in a coffee grinder and then only parts that would like is the dust that would come out but it was to hard to collect but I had a buddy taking chemisrty last year and we set off what I belive was 400 mesh with just ***tiny bit **** flash powder then the shit just went off, But what I do not get is you guys post saying you have this shit but ask us if you can set it off with a bic or will you have to use soemthing else which you guys allways say you have if you have why have you not allready set ot and then come here and TELL us about it not ASK us about it

— Posted by Joshbdaman on 9:55 am on April 7, 2002

For one thing, I doubt I would like to explane to my dad why the nozzel of his torch was burnt off. 2, the mf if heavy! It carry this huge ass gas tank and the equipment. 3, I don’t want to have my hand melted off. 4, I can fill of the black hole known as my head. and last but not least, I want to expariment of shit to see what happens, but I want to know what will happen first so I don’t half a peice of metal shot through my brain 🙂 I think I’ll stick with sparklers :biggrin:

(sorry for the caps)

— Posted by paladinpress on 10:00 am on April 7, 2002

My suggesttion to you is the first time you light  it use a hood and gloves but before that rob some caly molds from art calss and put 10 tablespoons full on the molds and try and light thatset the mix lean and the falme about four inchs and try that  but put the nozzle paralle to the flat side of the clay mold.

— Posted by MadBomber2 on 10:35 am on April 7, 2002

just get sum magnesium strips and a blow torch to set it off and if u did it right (which is obviously not gonna happen cus ure a noob) it will burn through stuff not explode so next time u make a weapon of some sort make sure u know what it fuckin dus and if it is stable cus we dont wanna c u burn a hole through the top of ure fucking head.

I Like what you wrote it was accurate and concise showing safety and enough compasion for the safety of a “Noob” but I have to laugh the fact you have post 12 times although that rarely can show intellegnce

— Posted by pyro131313 on 1:23 pm on April 7, 2002

exactly how much stuff does therme burn through? if i had 100g of thrmite how far wuld it burn through a concrete floor?

— Posted by paladinpress on 1:36 pm on April 7, 2002

Through a concrete floor I would not say more then two inches because the nature of concrete itself but I would bet on some major cracking, through other metals is where It is best.

— Posted by soulreaper666 on 9:08 pm on April 9, 2002

you guys are all wrong, it needs to be 2 to 1 ferris oxide to aluminum by volume, and you only need a piece of magnesium tape to get it goin(about 5000 degrees f)

— Posted by IcedMetal on 9:54 pm on April 9, 2002

Why does everyone keep repeating the same fucking thing.  Guess what folks, the one dude that said magnesium strip does NOT NECESSARILY need to be lit by a blowtorch was correct, I have done the same thing with a Zippo, it just took awhile but Zippos is very stable and reliable.

— Posted by MadBomber2 on 3:05 pm on April 10, 2002

So u r saying that u set off thermite with a god damn zippo? No way I have like 80 of em’ just laying around. I gotta check this one out.

— Posted by Egg411 on 3:30 pm on April 10, 2002

i dont think concrete will burn, though i dont know.  but how i hate the fact that everyone says to use a blow torch.  just use a fucking lighter with a heap of magnesium to get it going,  just set the heap of magnesium in the middle so the heat can rise up to the thermite to get it started.  if that doesn’t work then try setting of a small nuclear bomb,  that should create enough heat to burn it

— Posted by IcedMetal on 7:31 am on April 11, 2002

Get a butane lighter if you can buy one, extremely useful for any pyro/explosives anarchist. I’m not sure if thats what its called but it emits a blue flame. It lights magnesium so EZ and you don’t have to carry a blowtorch around during your little act of terror.
