bad way
I'm not a fan cheddite. Also, I wrote it here. Explosives based KClO3 are dangerous and weak. Further experiments will not be repeated. There are many
other, more powerful and much safer mixtures. KClO3 is (like bombs) very bad way. It is better to do nothing. LL

I tried burning a little bit of Vaselate and it did nothing, it burned a little when heated lots.
It turned molten and when I accidentally dripped a little bit of this molten cheddite onto the workarea a loud bang was heard.

forgotpassword: It would really help if you said what composition your "vaselate" was...
90:10 KClO3:Vaseline does tend to burn fairly vigorously if ignited with a hot flame, once it catches it actually releases a fair amount of heat. The
traditional crapbook wax/vaseline/chlorate mixture might actually be of some use as a thing for starting fires or something.
Also, didn't "Cheddite" originally refer to a nitrobenzene or nitrotoluene (nitroaromatic) and chlorate mixture? Wiki and memory say so...

Just as the bad idea to mix chlorate with vitamin C (ascorbic acid)...It sets some HClO3 free what is a good way to get ClO2 gas and spontaneously set
the mix into fire after undetermined laps of time --> not advisable to store.
Here they propose into this mix to use NH4NO3 and chlorate what is known to be a bad idea because of NH4ClO3 transient formation and resulting
NCl3....so very unsafe patent!

Moai
For those of you who like to tear and split wood. Laboratory of Liptakov developed a plastic explosive on the basis of ammonium perchlorate. (type
Moai ) VoD about 3200 m/s. Minimum water absorption, long-term stability. Content
NC 3 is not required. Everything else in the picture. Sensitivity to No.8. For the cumulative charge is not applicable. Low VoD. The ripping rock,
wood, bricks, wall composition is sufficient .... .......LL
To increase the VoD can be replaced by a part of the composition ETN, PETN, MHN, maybe MEKP, or EGDN, NG. But it is not tested. This would have to
give someone more experienced.

Nice work! and I like the face you molded onto the putty
I was thinking, what VOD would KClO3 and Sugar have, say a 50/50 ratio?
I would say a near full detonation could be achieved, as it is quite sensitive, it can be hit with a hammer and detonate when finely powdered.

KClO3
Do you try to ratio saccharose 25,2 and KClO3 74,8%. Oxygene balanced is +0,052. OB saccharose = - 116, KClO3 = + 39,5. But I thinking, that this
mixture will be not detonation. Without 5% aluminium powder. You can try...........LL

What was mesh size of the ammonium perchlorate used?

plastic
Hi,
ammonium perchlorate for plastic - mesh - sieve about 0,1 - 0,2 mm. Tested primary initiation, only 0,5g pressed LA , full detonation. Diameter 22mm
in wood. Interesting. The problem is only the price perchlorate.
Plastik can be used as an improvised incendiary way. The speed is about 1 cm / sec. Another possibility is to use as combustion fuel directly to the
resistor to initiate the LA. Or rocket engine. High temperature burning...........LL

AP plastic
Here is another example. It is interesting excluded elemental copper. It comes from TeACP. The composition was calculated to OB around zero. Parts by
weight per 100g: AP74, TeACP17, PIB4, 5W40-4, MB1. OB = + 0.137. With aluminum 1 = -4.6. According to deposit copper on all parts of birch was
complete detonation. I presume. Plasticity same as in the test above......LL

shock tube
If it is an unknown composition always equivalent No.8. Thus as 0.5 to 0.7 g ETN. However. It is only equivalent. For clear and comprehensible idea. I
can not really write what I use. It is an ecological initiator. Patent pending. And many tests. Equivalent is No.8 to No.10. ......LL

Cheddite 90/10 Ammonium Perchlorate/white petroleum
I was reading this pdf and i saw this simple mixture, Cheddite 90/10 AP/WP.
seems pretty solid. With a det. velocity of about 2500 m/s and create a cloud of chlorine. I haven't been able to experiment with it. I would guess
that it would have characteristics similar to AN/Al mixtures. Low brisances and difficult detonation. I haven't been able to find any in depth
research on this specific mixture. If anyone knows of any in depth literature on this specific subject or hands on experience with this mixture. I
would appreciate it. If any of my speculations are wrong please correct me. Just want to see if this is worth testing.
Videos of similar mixtures.

I have read the thread and i could not find comprehensive knowledge or in depth test results for this exact mixture. There are some potassium
perchlorate and ammonium perchlorate related mixtures but there aren't the same, they usually contain aluminum or charcoal. I would like information
on 90/10 ammonium perchlorate/white petroleum. Any other mixture would not share the exact same performance as 90/10.

Hi Keith- Welcome to sciencemadness.org!
Please read this FAQ about posting, it will help you decide where and how to bring up topics that interest you, and explain why I merged your thread
into the existing cheddite thread.

Cheddites are often said to be quite sensitive.
What does that mean in practice?
Im talking about Chlorate/fuel mixture only, without any added nitroesters.
Can they be used for bullet sensitive tannerite substitutes?

Important question is, which fuel will used. If someone use some fuel with dirty additive, some (high reactive) organic type dirt or add something for
increase power, Can happens, that cheddite will exploded or burned self. For example over 30C during storage. It is, I mean, the main dangerous.
Basic mix KClO3 + pure mineral fuel (WAX, grease, WD40 = solvent oil) is not sensitive on friction. You can try on the anvil. On own ranch....

Just looked at several sets of figures for drop hammer testing, friction testing on chlorate based cheddites. Some of them are more sensitive than
unphlegmatized PETN.
If you really want to make exploding rifle targets, go to boomershoot.org and check out their history of target mixture development for their annual
spring shoot. They have made several tons of this over 14 years time without a manufacturing accident (yet, you never know- they mix a lot of this
with amateur help).
Project Ethylene Glycol
Ammonium nitrate, Potassium chlorate, cheap ethylene glycol antifreeze from Wal-Mart. It works for any center fire rifle I have tried from .22 Hornet
up, no expensive Aluminum powder required. Don't try to store it, use on day of mixing. Will occasionally shoot for really brisk rimfire rounds too.

Thanks, but i need something that can be handled and stored for some hours.
Ammonium chlorate is not prefered.
I just wondered if some Miedziankit style stuff can be made sensitive enough.
Maybe with some manganese oxide or similar additive

Main reason not to store overnight is legal.
Look at the link. The people in Idaho make these targets before their 3 day long event, store them in an approved HE magazine but do not keep them
much longer than that. I don't think these are ammonium chlorate sensitized, they will fire immediately after mixing, but take quite a while to self
destruct. I would guess chlorate and glycol are quite touchy enough, but without testing? Can't say.
Spilled target material from grazed targets left outdoors in sunlight/moist air have spontaneously combusted after about a week, starting grass fires.
