In the far east recently I saw tiny barbeques about ten inches square, the
base being made from what i think was some kind of clay and had a stainless
steel rack to sit on the top.

They could easily be placed on a kitchen hob, so that you could have an
indoor barbi.

They were too heavy to bring one home. I'm wondering if anyone has seen
them for sale in the u.k.?

Or if anybody had adapted anything to make a miniature barbeque that one
could use indoors in the kitchen placed on the gas hob?
