I have been thinking ceramic smoker.
This is my plan.
Make a backwoods style, cabinet, 3 grills.
But instead of double walls, I can make it one wall of 1 mm stainless steel.
Also I will make ceramic block/lining, size 8" height, width 4" to 10", thickness 1/2" or 1". Ceramic lining can be inerted inside around the wall.
The side opened door will be also lininged by ceramic block.
For same weight and size, this cabinet smoker will have bigger grilling area.
and If one block is broken, you can simply change that block.
Production cost of 1/2" and 1" thickness will have less difference.
But shipping cost will be higher.
What do you want.
1/2" or 1" thickness
