Believe it or not I believe I viewed this just as I was in the middle of building my first stove, or I had just completed it.

Aside from moisture, Is the use of Vermiculite in a RS going to be a deal breaker if moisture isn't going to be an issue ?

I looked at both the melting point of Perlite and Vermiculite, Vermiculite has a higher melting point. Wouldn't this make it a better choice over Perlite, because of the higher temperatures in the Riser tube. :?:

Also, is it possible the higher temperature rating, the higher in R value of the insulation.  :?:

You're not going to melt either one and I would say they interchange equally well. Vermiculite is more expensive, here, so I use perlite. Higher temperature will only shorten the life of your stove. 1300F is plenty hot. Hotter is damaging.

Kevin, Thanks for the additional information on the interchange of either one. I have spent a bit of time on the net trying to find out which one is better to use for insulating and why? drunken 

I have even read the MSDS date sheets on the two and different Forums talking about Perlite VS Vermiculite, there were prose and cons with the use of both of them.

The conclusion I was starting to form, is that either insulation would work well if moister wasn't going to be an issue. I was just curious in knowing, if there were any rock solid reasons as to one being better to use over the other?

If cost is the only real difference in the two, Its not that difficult of a decision to make, if your trying to save a few pennies when you can. cheers

Hi all, i wonder if there is an argument for using refractory material in RS building, i know the guys who make their own forges etc use this material and they can melt cast iron in their home shops. The only down side i can see is the material does break down over the years or as an alternative fire bricks cut and shaped to suit, cheers Dave NE

Hello Dave, Here is two links that may help you?

http://www.refractoriesinstitute.org/aboutrefractories.htm

http://www.engineeringtoolbox.com/melting-temperature-metals-d_860.html

I would think the use of refractory material in your RS build design, would depend greatly on your intended use of your RS. :?:

You might try starting a new topic post in Ideas and research, This may help you with deciding on the incorporation of refractory material into your RS? :?:

In one of Kevin's many videos he has out, he had mentioned a video play list. To me it sounded like an excellent way to keep everyone's RS build videos in order by date.

I still been trying to figure out how to find this list ? I know this would sure help save me a little time in searching, when I want to reference something from a previous build.

Maybe a new topic post could be start explaining all this, to help others like myself.  Very Happy

Go to my channel and scroll down. I can't remember how many playlists I've posted. Need to do more, but I just don't have time.

The study of Rocket stoves is fascinating. While I begin to gather ideas and materials for my first rocket stove, I continue using my TLUD barrel to make biochar. I figure it will last through another 10 or 15 burn cycles.
I found that on cold days the stove temperatures dropped and the process cooled too much to sustain gasification and afterburn. My first fix was to add a surround to the stack flue. This past week I built a jacket for the barrel to increase inner heat. This Jacket is 1.25 inches from the barrel and will get filled with Perlite. I will fire it first time next week when I get more fuel ready.
I wonder whether the increase in heat will necessitate control of fresh air to keep the unit from over heating.
I tried to post a picture, but three attempts failed.
What an education all this is giving me!
