It is a Thai cooking stove made out of clay, there is a flat section in the middle with holes in it. On the bottom there is a window which can be turned into the wind or away from the wind depending on how much air you might want. Fanning this window works wonders when starting a fire, the ash falls thru the holes into the bottom section. The top has 3 rests that support a wok or Thai BBQ (I'll let others tell you about that) as well as a removeable section that can be left out so that you can feed the fire while cooking. This works well with birquettes, wood, or coal depending on what is available. One night we just tossed a bunch of coals from the camp fire in it as we too lazy to start it from scratch.
