Then you crush it and make grog (chamote) with it.

Interesting product. Temp wise it would stand up in a RMH.
Here is the thing about refractory mortar.
It sets up rock solid and it will crack on the joint with the rapid temperature changes in a batchbox.
Clay can crack on joints as well but is easily reapplied with a wet finger...
Believe it or not with proper support on the outside, dry stacking bricks works very well.
Another disadvantage to refractory is trying to clean it off to reuse a brick.
Clay mortar falls off into your bucket. Add water and rehydrate to use again.
In some high heat locations fireclay can turn into pottery and not rehydrate.
As soon as you are away from the core and riser, you can use regular Portland cement to build your bell if you wanted.
Nope, not really.
