Hexamine Blasting Cap Composition

Materials

Hexamine (Not the blue stuff, thats Trioxine. Hexamine comes in white pellets, Available at Gunshows and Military Surplus Stores )

Citric Acid (Avaliable at many stores that supply goods for canning foods)

Hydrogen peroxide (Drug store varients are too weak for this composition, Instead obtain at least 30-35% Hydrogen peroxide. This is used commonly to bleach hair, get it at a beauty supply shop)

Mortar and Pestle

Pint Jar with securely closing lid

Coffee Filters

1: Grind the hexamine with your mortar and pestle to a fine consistancy then place 1 teaspoon of it in your pint jar

2: Add to this 2 teaspoons of of dry citric acid.

3: Add 1 ounce or about 4 and 1/2 teaspoons of hydrogen peroxide

4: Cap the pint jar and vigorously shake for 10 minutes to make certain you have a well mixed solution. Please do note that larger batches then what I have described can cause heat and detonation. So just keep to small batches and if you notice any heat in your small batch during shaking stop shaking the solution and place it under a steady stream of cold running water.

5: Place this solution in the refridgerator for around 8 hours. You should see white parcipitate form in the bottom of the jar

6: Filter the Solution through a coffee filter, then wash the jar with rubbing alcohol and wash the collected composition with it.

7: Discard of the solution

8: While still in the pasty form scrape it off the coffee filter with a wooden toungue depressor. load into your cap casings, this recipe will make one cap of sufficient power to detonate most ANFO mixtures. If you must save the mixture in a dry form ensure you wet it down with alcohol before attempting to handle it. as it is shock and friction sensitive you dont want to become like Kurt *Stumpy* Saxon do ya ?

HMTD, is another organic peroxide, like AP. HMTD however is less stable than AP, and less powerful. It's something good to get experience with but not something that is as nice as AP for safety and etc.

[THErAPIST]

For one, ANFO mixtures should be detonated with a cap that also has a booster charge. HMTD is MORE stable than AP except that it is more sensative to impurities than AP and it also forms unstable salts when it's in a metal casing.

HCL is also used at times to make HMTD but you've REALLY got to wash the HMTD to make sure that all acid is washed away. The VOD on HMTD is slightly lower than that of AP, and AP is more brisant, but it's easier for some poeple to make.

Personally Ive never heard of any problems detonating ANFO with this mixture, Would sensitizing the ammonium nitrate with nitromethane instead of something else be why ?

[THErAPIST]

Detonating ANFO, being Ammonium Nitrate and Fuel Oil, with just HMTD as a blasting cap won't be extremely reliable unless the cap contains more than a few grams of HMTD, or unless that cap has a boster charge. This is because ANFO can become dead pressed. when ANFO becomes dead pressed it can't detonate all of the charge because the front of the detonation wave doesn't carry enough shock and heat to detonate the extremely compressed explosive.

Something other than Fuel Oil can sensatize Ammonium nitrate better though so that HMTD will be plenty. NitroMethane is one such thing. The resulting mixture being called ANNM. ANNM is not only much more powerful, but it's also easier to detonate and much much harder to deadpress. This is especially true if 5% fine aluminum flake is added in with the ANNM. The Aluminum raises the level of heat upon detonation.

I'm not saying that ANFO can't be detonated with just HMTD, I'm just saying that it's not as reliable as it would be if one were using a booster also.

Also in your preperation you don't mention washing the HMTD with a solution of water and baking soda... Baking soda should be a definate in washing any explosive compound because it neutralizes any residual acids that can get into the crevices in the crystals. This is especially true with HMTD because ive seen the results of what happens when allt he acids aren't washed away. just it setting there all on its own drying it has detonated (not personal experience) because all the acid wasn't washed out or neutralized.

Having the reaction vessle in a bowl of water and ice while mixing the acids and such is also a good idea. If the reaction isn't cooled enough when adding the peroxide it can also run away. Doesn't happen often at all, but it can happen.

Thanks alot =D. *blush*

Heheh, Im sure I sound like an idiot but I had been under the impression that what we had been making the whole time was ANFO. I do apologize for making such a mistake.

Also many thanks for the advice on the saftety issues, I had no idea.

[THErAPIST]

Tis not a problem. After almost having part of my hand taken off by AP I appreciate any help or advice that I myself get, and I'm happy to help most people out. Before you ask, I didn't have my hand ripped appart or anything.. I just had it turn purple, it was numb for a few hours, I got the hair burned off of both arms up to the elbow, I had part of my eyelashes burned a bit, and I couldn't hear jack shit for about 30 minutes. That was from about .5g of AP if even that much.

We were talking about ANFO though, I was just making an example is all :wink:

ANNM could be considered ANFO....To someone who doesn't really know this stuff, NM is used aas a fuel for some things, and any impurity in the NM is usually oil..So it could be a "fuel oil"..

[THErAPIST]

yeaaaaaahhh.. na.

theres a big difference between the two. ANNM is used in some circles as an improvised c-4 equivalent.. It can't really be considered ANFO, as it's nothing the same really.

if people don't know then they just learn the correct teminology that's all :D

[kbk]

I agree, I was just saying that he may have gotten confused because it is used as a fuel...I know the differences between the two...Not everyone does so I was trying to clear things up.

[Douchermann]

I don't think its used completely as a fuel i thinks its used with something like alchohol too (nitromethane) Fuel oil by deffinition is keroscene, its not deisle, its not gas and oil its keroscene (i know most of you know that, but i have a friend who doesn't and he always argues with me about it, and any time we argue i don't have a dictionary on hand)

[THErAPIST]

in the sense of a blasting explosive known as ANFO, diesel, kerosene, and a mixture or 50% gasoline and 50% oil all comes into use under the term fuel oil. this isn't technically correct, but when using ANFO as a blasting agent, any of the 3 things can be used and has enough accuracy at the time.

ANNM couldnt be considered ANFO though as ANNM has a velocity that's twice that of any Ammonium nitrate and gasoline & oil/ diesel/ kerosene mixture

as a side note, i was asked by a judge to blow a stump from his yard a week ago... i really dun know if i want to do that though. I would use ANFO using kerosene if i could, or diesel which is a hell of a lot easier to get here for some reason. but tats only IF i did it. I'd also throw a few sections of chain link over the stump with a tarp over that weighed down at the edges by bags of mud as a blast mat to contain any debris that would be thrown...

ah the interesting points in life as they serve to confuse us all...

[Douchermann]

Lol that would be something id sorta choose not to do unless the judge is okay with that kind of thing.... in that case do it all you want and if you get caught by the cops the judge will probably set you free :D
