This barbecue is made of diatomaceous earth from Suzu city, Ishikawa Prefecture.
It has a good capacity for heat accumulation and storage. Its charcoal consumption is therefore less important than for a conventional barbecue.
Diatomaceous earth emits infrared rays that promote immediate cooking without altering the umami flavors they contain.
The barbecue is light and is placed directly on the table, within reach of the guests who can then grill as they please fresh meat or marinated, fish, or vegetables.
After several uses, it shows cracks due to fire charcoal. This is normal. There is no problem as the heat remains concentrated inside the barbecue hearth.
