Each Fire Pit Art® creation is made from one quarter inch thick mild carbon steel and has an applied iron oxide patina on the outside. The interiors are hand rolled with a dense high temperature resistant coating and have a one and one half inch diameter rain drain in the bottom. There is no required maintenance even in cold, harsh environments and can be left outside year around. These fire pits are safe on wood or composite decking if they rest on a one and one half inch thick (or thicker) stone base that should be approximately three feet square. Artisan crafted fire screens with a wood loading hatch are available for most models. All designs are easily adapted to propane or natural gas equipment. Each fire pit is hand crafted and individually numbered on a small brass plaque attached to the base ring.
