I would think that, while American hazel might be blight resistant they produce material of a much smaller diameter than the European vartiety. I mentioned before that are many blight resistant varieties to be found at Burnt Ridge Nursery. However as I understand it, most of those were developed via breeding efforts in Oregon and reportedly their resistant may not hold up under disease pressure in the east. You want stick with varsities developed closer to where developed to be resistant in the region you reside in. The Northern Fruit and Nut Growers and the Indiana Fruit and nut growers associations are a good source of info.

Yes, quite helpful. Thank you.

So it would be fine in the oven design posted above?

However it is not suitable for use in a flame path when food is also present.

The design I am using is also sealed. It is a "white oven".

I'm sorry but I am unfamiliar with the rocket pizza oven build.
I use a Walker black and white oven for pizza making.
What part of the build do you want to use superwool in?

I am hoping I would use it, in some way, in the construction of the stove (the J-tube) itself, surrounding the burn chamber, and lining a heat riser.  In the plans provided the stove, the  combustion chamber is made of fire brick and and ceramic fiber board.  The heat riser is made of ceramic fiber board cut to shape and held in place with a metal frame.  It would be much easier and cheaper to make one  where superwool is lining a round conduit such as shown here:

If you go to minute 1:44 of the trailer linked to below you will catch a glimpse of the j-tube as per the original RSPO plans.  Again it is made out of firebrick for the burn chamber lined on the outside with ceramic fiber board and fiber board for the heat riser all encased in sheet metal and supported by a metal frame.  I think I would still use the fire brick and combustion chamber design but would want to use a riser lined with the Superwool rather than the straight walled ceramic fiber board.

Superwool is perfect when used in a riser., although after heating beyond 1400F, a mask should be used if handling a used riser.

Are you familiar with the rocket pizza oven build? What would a mod utilizing Superwool look like?

So, I was thinking after mucking my way through the first 2/3rd of the standard rocket oven build and shuddering at the imperfection of it all, "what if I used a 30 gallon drum nested in a 50 gal drum?"  Seems like it could work, obviously a reduce volume capacity is a fact. Any logistical red flags aside from the reduced volume?

So can this material be used for the a rocket stove and integrated with the Rocket Pizza Oven? I am at the point now where I need to consider constructing the rocket stove component and I am not enthused about the expense of ceramic fiber board.

We did a small area in in low lying / ephemeral pond area.  We coppiced primarily willow and cottonwood. In addition we planted more willow with the live stick method. The purpose of coppicing these species was to begin have several areas producing 6 to 12 foot long sapling-like material which can be used to make fascines and lots of live stakes to help control erosion along a stream bank along the northern edge of the property.  It was very evident that deer are going to be an issue. Every stool that was protect by piling sticks and branches over them (i.e. minimally thwarting deer browse have shoots that are over 5 to 6 ft tall). Everything that was not protected is knee high.  

Here is not interesting research I found on coppicing / copparding  / pollarding in relation to deer browse.  Basically, the higher the cut, the less deer damage.
