Hey permies,

I'm wondering if anyone can help me with identifying this firebrick or insulation in this rocketstove... I want to get some because of how thin it is, but I don't know what it is, so I don't know what to get...



HELP !
Thanks

John John John... bro... you have graduated from standard steel to stainless and although stainless isnt no tungsten it sure as heck better than going backwards to aluminum. goodness my friend that was the most silliest idea i have seen to build an aluminum rocket stove. i know you are not thinking about that are you? if you want the bricks thats one thing and its the soft white insulative fire bricks and you can order them online or get them from your local brick and mortar, brick and mortar store. i love your trial and error and seeing you thinking of using real high temp metals is cool but i swear if you build an aluminum rocket stove i will come find you personally and slap you with a fish.

you know this system is so weak, an open air fire from a match whoops his temps he is getting from that weak system. i cant even call his system a rocket stove.

What?

Its not mine, and I'm not building one from aluminum.

Back to subject:
I want to know what type of insulation this is. Does anyone know what tyoe of insulation this is?

https://m.youtube.com/watch?v=vMMO65b8y6k#

So far I've read down into the comments and he said its "pottery kiln insulation. You can cut it with a knife". So what is that composed of, and where do I get that?

Stay on subject

Thanks Fstyles . That's the answer/info I'm looking for hopefully. I will have to check out that link in a minute, I'm on my blackberry.

One guy said you could use ceramic tiles? That would be relatively easy for me to get also...
Input?

Cheers

i was concidering the ceramic thing for a while until the research informed me of ceramics temperamental temp shock sensitivity. i think i wouldnt do the ceramic tile thing since they are prone to temp shocks and can fracture very easy during fast heat ups and cool downs. if you do want to experiment with ceramic tile you will have to cut them into 2'' or 3'' slices to avoid the temp shocks and in my mind is not worth it. but go ahead give it a shot i wanna see pics though.

Looking at his video the insulation appears to be ceramic fiber board. The stuff comes in various grades, thicknesses, and etc., available from refractory supply houses and even on Flea-Bay. A lesser material is vermiculite board, which has less insulation value per given material thickness.

John Mc D : There is no insulation outside of the much cooler running fire box and that is very much the point that the anti-metal people have been trying to make!

As soon as you insulate around the outside of the metal eventually you will get higher temps and metal fatigue. It is only that the Chimneys Metal shown in the video

is un-insulated that allows it to shed enough heat to survive!


This is an early prototype model from September 2013, a project since abandoned, If you click on YOUR link -then immediately below the video display screen you will

see in the lower left corner the words Bristol Rocket Co if you click on those words you are sent to the You-tube home page of Bristol Rocket Co


This should start the latest video showing the latest model ! 1st) the certificate of design registration ~ 00:25~ minutes is not the same as a patent, it only stops other

manufacturers from making products that look substantially the same,* and has nothing to do with performance !.

Note that at ~02:05 the speaker makes the claim that he has decided to manufacture the Bristol Rocket Co.s version of a Rocket Stove from mild steel "because mild

steel is so much better at high temperatures than stainless steel" .

This is not a scam, this is a sad inventor with a problem in design and equipment who refuses to see ether failure or reality !

Chalk up one more to the Huge Boatload Of Steaming Stinking CRAP to be found on U-tube . For the good of the Craft . Big AL

* a certificate of design is so useless that an honest patent lawyer will never file for one !

or it could be kaowool board which can also be found at the same website. kaowool board

looking at the sucky aluminum unit with such low burning temps he could being using just about anything with out it getting hot enough to burn so your guess is as good as mine... i would not use that video as an example or suggest using the materials he is using.

F Styles, you're right, that's the best example of what not to do! Angled feed, where we can see a good flameback and smokeback. It's known not to work. Bigger than system size feed, with no cover. Bad again. Insulated, while the heat riser is not, that would tend to revert as being the heat riser, due to the insulation and 45° angle. Non insulated riser.

The only good point, aluminium melts around 660C° but alumina melts at 2072C°, and that protects the aluminium behind of oxide formed, as long as this one is not insulated.

John, look at kaowool, board 607, ceraboard. Mind you, the later is reserved to profesionals who know what they do with ceramic dust. Realy realy dangerous stuff. If you don't have a business number, you can't buy any. Exept may be on ebay. Or bulk in china. But you don't want to.

THa apostol guy is here

If you want to ask him exactly what this is.

I saw him on that thread too. But that's a 5 year old post, so I guess he's been making rockets for at least 5 years, but I might not reach him here, after that much time. Especially sice he uses metals, and you guys don't reccommend metals, he may be long gone outta here. People will go where they are recognized and appreciated. So he may not be here anymore lol

I marked this thead as resolved already. I would delete it, if I knew how..

Thanks anyway guys
Cheers

i dont know John, they may forever keep this pooched thread just in case if you have a bad burn day you can always come here and open his video and chuckle knowing whatever system you built is better than his. Or it may end up being known as the "curse of John Mcdoodle" you dont want the curse. i think i must go wash my eyes after viewing the video.

There's no Delete button in either view.... The thread will fade away on it's own once everyone stops posting in it

come on i was having a good laugh giving John a hard time... of course there is no delete button. John you crack me up buddy. we can always haunt john every once in a while by posting a comment to keep it breathing. the "McDoodle curse" will haunt you if you build a low temp (aluminum) metal stove.

Here is some insulation that you might actually be interested in, as you can make it any thickness you want. Is it toxin free? I have no clue.

Rutland is a standard name brand of refractory cement, and perfectly safe to use. This product, though, is not an insulating refractory which is what is needed. The price is also pretty high unless you have no local source. You can get a 50 pound bag of dry castable (more than twice as much as that bucket) for around $55 depending on your location.
 
I agree. Here's the link: http://richsoil.com/email
