Fire ring
From Wikipedia, the free encyclopedia
A fire ring is a device used to contain campfires and prevent them from spreading and turning into wildfires.
A fire ring may be nothing more than a short, wide section of metal tube, partially buried in the ground. Slightly more advanced fire rings may be partially covered with metal bars so that the fire may be used for cooking. These types are seen at many campsites. Fire rings in urban areas, such as on beaches, may be made of poured concrete. Makeshift fire rings can be constructed out of a ring of stones where pre-constructed rings are not available (care should be taken as some stones can explode when heated due to trapped gas pockets or thermal expansion).
