Q: Hello Dr. BBQ,
Could you please tell me what is the material used in Japanese-style BBQ as an insulator and refractor (looks like a cement based material of some sort).
Thank you,
Slaven
A: Hi Slaven,
It seems the popular ones call it “Space Age Ceramic.” I think there is also one that is made of a concrete based product. The old ones were made of clay but didn”t hold up well to high temps or any abuse.
