Looking for a cheap solution to building a burn core  RSS feed

I've been experimenting a lot with burn cores made from Ytong Blocks. When I did a test with a batch box core, I saw the blocks falling apart due to cracking on the inside, probably caused by the vast temperature difference between inside and outside.

I've been using the ytong blocks for their cheapness and ease of handling.

I was wondering though, if I was to line the ytong on the inside with ceramic boards like on the link below, would the system hold?

Any suggestions on cheap and durable building materials are greatly appreciated!

@Ivo,
That material could be the right kind to line the AEC blocks. It will withstand the heat, is insulative but isn't very durable, I would say.

Being not very durable meaning it'll fail in short notice?

Would the same material lined with some kind of refractory hold?

Not being durable in the sense of easily damaged by sticking in fuel.

@Peter:

Thanks for your reply.

Check following link out:

Is this something too good to be true? If it is thrustworthy it is a damn cheap way to make your own firebricks in any shape wanted. It involves some "chemistry" and work, but should be doable...

Very curious in getting some feedback on this.

Regards,

Ivo S.
