I am seeing yellow and white interiors, which is good. Tell us a little more about the cellular concrete outer slabs? I think you have something there  

I had some leftovers of our new house, they were scrap but I managed to save some.  Here is some info on it, its so easy to work and ultra light weight:

Thanks for the input!!

I choose to make it out of high alumina bricks because is what I had handy.  The outer shell is cellular concrete.  Ive done a couple of one hour+ runs on the forge and the outer shell stays around 90º (pretty much ambient temp).

Ill move up the cone, to keep it from melting.

Something I see that I think may be a problem is having your cone inside the box like that. I think it will melt away quite quickly. I'm sure someone with more experience will correct me if I'm wrong soon, but I would pull it back in a bit. Also, the hard brick are durable for the bottom, but aren't as insulating and suck a lot of heat out so you are wasting a lot of gas to heat them on the sides and top. Do you need them there? Can you remove them and still be in your 300 or so cubic inch size? What are your current cubic inches?

You are right in the cone remark, it became red after a while. Although the burner tube did not heat that much.  I will pull it up an inch or two. 

Im around 280 cubic inch
