Once mixed, is there a shelf life for tannerite (aluminum powder and ammonium nitrate)? Does it lose effectiveness over time?
yes, it will clump by absorbing atmospheric moisture leading to failures to detonate after several months. the components are meant to be stored separately in hermetically sealed containers in cool, dry, place.
A little off topic but I was at a backwoods range and saw a dude roll up, grab a tub of tannerite, mix and shake it up a bit. Then he put it out in the field about 20yd out and started spraying at it with an AR. He missed a bunch but he did hit it a couple times, but no detonation. He shot more and got increasingly frusturated that it wouldn't explode. He got maybe 3 or 4 hits total. He mentioned I should try hitting it, and I put a .308 round right through it and nothing happened. I shrugged at him and said maybe it wasn't mixed right or got wet or something. By now he was totally steamed, and grabbed his pistol of some sort walked right up to the damn thing and shot it at his feet.
It went off that time no problem, shredded his pants up good, legs were all scratched up and bloody and he fell right on his ass.
He was okay, considering he about got his dick blown off.
>buys it from the store
>doesn't order 500lbs online for a severe beaver problem
U wot mate?
AN is super easy to buy. Just about any feed mill will sell you under 500 lbs without taking your deets, it's the powdered Al that's hard to get in decent quantity.
In this vein, anyone know what the recipe for the rimfire sensitive formula is?
That shit is way spendier than the rego stuff, more than I'm willing to pay, but sensitive to .22 LR and no. 4 birdsong sounds super fun.
No. Your only worry is that AN absorbs moisture readily from the air. If it's sealed in an air tight container then this is not an issue. Mixing the AN and AL does not create any kind of chemical reaction, so mixing does not have any effect on shelf life. The AL just acts as fuel and the AN acts as an oxidizer when the mixture is set off.
Legally speaking: You aren't supposed to store or transport the mixed product. It's supposed to be destroyed on the same day you mix it.
Mixtures can be between 5% to 20% AL. I have heard that the lower % AL mixtures are more sensitive, but I have not tested this.
Protip: If you're on 4chan, you're probably on a watchlist. According to the Snowman, everyone is on a watch list for something or another. Watch lists kinda become useless when you have millions of random people on them for stupid reasons. Buying fertilizer is not all that suspicious. I can practically guarantee that you have purchased "suspicious" chemicals in the past without realizing it. It's likely that you're already on a list for shit that you never even thought about.
Once mixed the shelf life of flash powder ( which tannerite is ) in a tightly sealed no oxy dry enviroment is 3-6months.
But the problem is it can become sensitive or insensitive depending on the mix
It isnt an explosive.... Until mixed.
There is no federal law about transporting ingredients.
Or else thousands and thousands of chemicals in everyday use whould have to be tracked and regulated.
Because it's legal for US citizens to make explosives as long as they destroy them on the same day at the same location etc. etc.
It's not considered an explosive until you mix it. The individual components are totally legal to own and all that.
No. A destructive device is a destructive device. You can buy gunpowder legally, but if you pack it into a pipe and screw the caps on with a fuse, it's an illegal grenade.
Actually it is.
In pyrotechnics a flash powder is any metallic fuel and an oxidizer.
The metallic is aluminium and the oxidizer is ammonium nitrate.
It is much more stable than say. Perchlorate based mixes.
But it is still a flash powder mix.
It's a bomb though right? It has a case and explodes.
>yield is shit
How much would you need to make an equivalent to a 120mm shell?
Is there a legal way with bigger yield for a similar price?
>It's a bomb though right? It has a case and explodes.
No. If it was considered a bomb it would be a destructive device. Read up on the various definitions for clarification.
Fireworks are explosives with some kind of casing as well.
Well that and compounds that are shock sensitive or heat sensitive, instead of requiring shock and heat together are hot garbage for fighting. Do you really want your car bomb to go off before it reaches the target because of a lucky rifle shot?
>Use the tannerite to initiate the acetone peroxide.
Lol, what. TATP is insanely sensitive. It will go off if you drop it on the ground or touch it with a lit match. Tannerite is far less sensitive than TATP.
Using TATP for anything is ill advised. As far as I know, it isn't used in any professional or legitimate military capacity, and I don't think it ever was.
You need to have a magazine that meets the requirements.
Then it is just like an ffl application.
Get a b license. Start a stump and obstacle removal business.
Fill out papaer work.
Get visit from feds.
They will inspect your magazine.
If you pass the backgrounds they will issue your FEL.
You don't need a FEL to make explosives for non-commercial use and the ATF will be reluctant to give you one.
An FEL also has little to do with making destructive devices i.e most bombs.
Tatp has not been used in military applications. Because it is so sensative.
But it has been used in paramilitary and terrorist groups because it is easy to make.
You can make it less sensative. But yeah it is a ticking time bomb. But it works great as an initiator for less sensative mixes like ANFO.
Iive made 5gal of ando. Filled a glass graduated cylinder in the center of the bucket with TATP, closed the lid. And place a 1lb of tannerite on top of it. Centered on the TATP.
Made a nice boom when hit from 300yrds with a 300wm.
does adding oxidized iron powder to tannerite affect it in anyway?
Yea a magazine.
As in a container for the storage of explosives.
A FEL is the only reliable way to get access to detonators and stable compounds used in comercial blasting.
No reputable comapny will deal with you if you dont have one.
The display pyro and special effects company I worked with for 10 years had a FEL.
Why? Because we used blasting caps all the time. ( bullet effects)
>Yes the ammonium nitrate will clump and become inert as soon as it is exposed to moisture in the air
Jesus, what do you people think it is, some kind of super sponge? The AN is exposed to air when the customer goes to mix it in the first place. If it's left exposed to air for a long period of time, it will absorb moisture. A few minutes isn't going to make any difference.
Assuming I read the law right, any explosive that is not a nuclear or chemical weapon in any quantity you so desire.
As long as you use it within 24 hours and make it on site.
>I cannot predict local or state ordnances prohibiting the use or possession of explosives, this is strictly federal law
You say that like there are not books of regulation controlling every aspect of a magazine and its construction.
The easiest... A type 2 or type 5 portable magazine.
A shipping container with a 2 inch pine floor and double 5/8 drywal. The door at one end welded shut.
And the entire container painted red.
Mounted on a concrete slab, remote from any inhabbited structures, and marked with a placard ( mounted at an angle. )
And protected by barricades of earth or. Of thick concrete walls.
Lastly the entire structure must resist a round of M2 ball from 100ft fired perpendicular to the wall of the magazine.
So some times you need to weld1/4 steel to the container if it isnt a thick enough wall.
so i guess you could say your friend has an explosive temper?
As a follow on: I use anfo and an-al (tannerite) legally and legitimately to clear log jams out of a creek that runs through my family's farm.
I mix everything on site. I use a hammer drill and a half inch drill bit to bore a hole in the logs, insert a (made onsite, homemade) electric blasting cap, then fill with the explosive mixture. Retreat to safe distance, complete circuit, watch logs splinter.
The guy didnt have it mixed well. . im betting ther was a well mixed section At the top.
Whe. He shot it with a pistol he was shooting down on that well mixed part.
Also the reason he didnt get hurt as bad as he should have. The a&b were not well mixed.
listed mine backwards.
Should be 7 parts KCLO4 to 3 parts German with 1 part sulpher.
Which is close to what you have listed. .
In pro pyro we dont use a stoichiometrically balanced mix, which would be 3 parts KCLO4 to 8 parts german gray.
Any big jobs I ask the Sheriff to supervise.
Since he likes blowing shit up too he usually does. Occasionally I'll even get some 'assistance' in the form of the Fire Marshal, Sheriff, 2 deputies, and the 'bomb squad' trailer (a horse trailer with hazmat placards) bringing out some TNT sticks.
Fuck black locust trees btw.
Doesn't change the fact that an-al mixed with anfo is the most used IED mixture. Especially adding in you make your own blasting caps. If the government decided they didn't like you you'd have no chance.
Wont cut the log, just make a lot of noise.
Hell back in the day when my grandpa was buying dynamite over the counter he was still having to pack sticks in bore holes, and dynamite is literally nitroglycerin soaked into something wrapped in wax paper.
Models and other art stuff.
They also carry iron oxide powder, used in paints, pottery, and thermite.
Also cobalt and other heavy metals that can be used as poisons or fire coloring.
Explosive forces generally have to be contained to be effective. If I were to lay a stick of c4/dynamite whatever, on the ground, sure it'd blow a hole, but it wouldn't do much cause all the explosive force is going up, into the open air. Now if I was to dig a hole, drop the explosive in it, and tamp it real good (Pack dirt around it) then the hole it would make would damn near be three times the size.
Potassium perchlorate in a .223 brass, crimp the mouth and seal a model rocket ignitor through the enlarged flash hole with RTV sealant.
The perchlorate takes fucking forever to make but will set anything off, and the detonators fit down my half inch bore holes nicely.
I hate working with dynamite.
The nitroglycerin gives me headaches.
We only use it as a booster if we dont have cast boosters. ( austin powders orange caps)
To set off anfo.
I did a lot of road blasts, and some contract work with mines ans snaller quarries
Never made ETN, will give it a look. How hard is it, and is it something that can be done safely on a tailgate?
I prep the casings for my detonators well ahead of time and only mix the actual explosives on site. Usually do 50 at once since they fit nicely in the plastic .223 ammo boxes, and since the yield of perchlorate is enough for about 15 detonators I usually use 2 per hole and typically have to blow the log in a couple different places.
Not that hard, although you might want to keep some ice around.
When ETN meets aluminum, in foil form or powder form, it becomes way more sensitive to heat and shock. Nobody has any idea why this is. Other than that, it's essentially the same as its cousin PETN, except Erythritol is easier to find than Pentaerythritol.
Very carefully smash the mouth shut with linemans pliers that have electrical tape on the jaws. Its fast and violent enough you dont have to create a pressure vessel, just keep it in.
listen dipshit, there are 2 seperate laws that control what you're proposing
the first law governs explosives and chemicals, and the second law governs devices that launch, amplify, direct, and/or initiate the explosives/chemicals in such a way as to cause injury or death.
explosives have a very legitimate purpose in everyday life, and the government understands that, they just want to keep kids, terrorists, and morons like you from easy access...but you can play with a few things here and there and skirt pretty close to felony territory without arousing the mighty hammerdick of pounding-in-the-ass federal prison.
destructive devices are a whole 'nother fucking ballgame and are expensive as fuck and hard to obtain. They are for serious collectors and people that know what they're doing.
you obviously dont.
so stay the fuck away from my fucking hobby before you blow your tits off and they regulate my toys harder
Yeah... Thats a lot more juice then my handheld box delivers.
Try ptfe and 25% by weight al.
It is a good mix for caps.
For more stubborn explosives pack cap with ptfe/al for 3/4 and picric acid for the last 1/4.
Picric acid and humidity dont like each other.
I blow log jams only once or twice a year, but theyre monster clusterfucks. I use the ATV battery because I need my truck and ATV to get me and all my tools down there to work on it.
>for every day of blasting is at least four of chainsaw work so the logs actually go somewhere when theyre blown free
Picric acid and humidity love each other.... That just makes it crapy for what your doing because you need because damp picric wont detonate reliably.
Yes powdered Teflon.
It is an energetic polymer.
Oh trust me i know. The blasting is 30 seconds of easy. The rest of the work is what sucks.
Do you know how much it sucks to do a road cut?
Its a week of drilling and clearing trees.
A day of explosive prep.
5seconds of blasting
1 week of haul away
Its a shitty filler because it needs a fairly high initiation ratio.
Too much AN based explosive with 1 detonator and you get a small explosion that throws the rest of your explosive everywhere.
It does have its uses though. Its low detonation velocity makes it an excellent excavation explosive, and its cheap and safe to handle.
A lot of road and quarry blasting is done with slurry ANFO for these reasons.
We use anfo for road cuts but we use cast booster with it. Never just anfo alone.
One of my professors way back in college was developing anso. An+ soy oil. For use as a green explosive. For doing work in areas that had environmental issues with the use of fuel oil.
For the anon that wants to wave a pipe not-a-bomb around as a protest.
Can I suggest that a sealed pipe full of stable explosive, and nothing else with no means of actually detonating it wouldn't probably be classed as a bomb.
Your dick must be one huge callous void of any nerve endings. Are your blind and how hairy are your palms?
You ideally want 34-0-0 AN
If it's prilled, it's probably coated with a fire resistant material
For best effect, grind the AN in a dedicated blender that has never seen organic material ever
Mix at a 10% weight ratio with aluminum powder that has a mesh size of at least 400. 1000 is optimal.
Pack tightly inside a container that will not easily rupture. Baggies and Tupperware may work occasionally, but harder containers exponentially increase the reliability
Calculate your NEW and figure out your standoff using a respectable K factor
Don't build a bomb
Attaching an ignition source will land you in prison
>insert a (made onsite, homemade) electric blasting cap
How exactly do you make one? How do you set it off? I'll be buying a chunk of land in a bit, and I know there'll be stumps to remove.
On a humid day with powdered AN, you'd be surprised what a few minutes can do. I've come back to a mortar full of water before. Prill form is less susceptible but i think some are coated for this reason.
Perchlorate... and an ignitor... for a detonator?
Absolute bullshit. Potassium perchlorate is just an oxidizer. Not explosive without fuel. An ignitor would do nothing. Ammonium perchlorate can be explosive but is incredibly insensitive.
>Shooting tannerite to initiate TATP
Why? The acetone peroxide is a primary explosive. Almost anything will set it off.
Rig up a cable leading to a chandelier bulb with gunpowder (nitrocellulose) inside and complete the circuit when it's time.
RE Factor- 1.6
Also Called- Erythritol Tetranitrate
Synthesis- ETN is made by nitrating erythritol through the mixing of concentrated sulfuric acid and a nitrate salt. Ammonium nitrate is commonly used for this type of reaction. (Potassium nitrate and drano can work) The erythritol is added to the mixture to begin its nitration.
The Problem- The availibility of erythritol(C4H10O4) is the question. Where can i find it? Are there any alternate synthesis routes involving less easy-to-find reagents to find than erythritol itself? How about the direct synthesis of it?
Brief Explosive properties- Long shelf-life.One quality this explosive has, that PETN does not, is a positive oxygen balance. Having a positive oxygen balance means that ETN possesses more than enough oxygen in its structure to fully oxidize all of its carbon and hydrogen upon detonation. This can be seen in the equation below.
C4H6N4O12 → 4 CO2 + 3 H2O + 2 N2 + ½ O2
Whereas PETN decomposes to:
C5H8N4O12 → 3 CO2 + 2 CO + 4 H2O + 2 N2
Hexamine is widely commercially available and if nitrated will give RDX.
This. Not only transport but storage as well, unless you have the proper explosives permits.
To answer your question, the mixed explosive should have the same shelf life as the ammonium nitrate component alone. If you keep it dry and sealed, it should be good for years. Expose it to moisture or humidity and it'll go bad in short order.
But regardless, the hazards associated with storing live high-explosive materials aren't something you should take lightly. Just look at the Forestal fire as an example of how fucking hazardous this shit can be.
