Will cladding crush ceramic blanket?

Posted by Jason

Rado,

I enjoyed your CD and have progressed on my oven project to the point that I have started thinking about the concrete cladding stage. As I understand, the concrete cladding is applied after a ceramic blanket. My question is whether the concrete will crush the lightweight ceramic insulating blanket, or will it be fine? Also, should I put 1 or 2 inches of blanket on the dome?

If anyone else is getting firebrick in Southern California, I found 2600g/cc fire brick with 40% Alumina content, and 3200 deg. F ratings for $2.71 a piece. Email me to find out where. I was amazed because they were over half off everywhere else I looked. Anyway, I am excited about the oven.

Thanks again Rado.
